How to open sealant with a gun. How to use a sealant gun - step-by-step instructions for a beginner

Sealant is very often used in construction, everyday life, car repairs and other areas. But it itself is sold in inconvenient cardboard cases or plastic packaging. You can get sealant from there, but it’s not easy to apply it nicely. The sealant gun allows you to simply and accurately apply this substance even to the most difficult to reach places. This article describes what kind of pistols these are, what types exist and how to use them in general.

Construction sealant gun

The sealant gun has such components as a guide, a trigger device connected to a piston system, and a handle. This mechanism itself is empty and is of no practical use without sealant. The latter is purchased separately and inserted into the gun. Only then is it used for its intended purpose.

Using a caulking gun is simple and profitable. The composition is consumed less and more efficiently, it is easier to lay and pour into cracks, so in construction and in many other areas you cannot do without this mechanism. The sealant, depending on the type of device, can be used in both hard and soft tubes. And some designs also allow you to fill mixtures you prepare yourself.

There are many types of caulking guns available on the market. Their operating principle is approximately the same - the sealant is squeezed out due to the applied force, pressure from the rod part or under the influence of air.

By type of design, pistols are divided into:

closed (cased);
semi-hull;
skeletal.

In addition, they are often distinguished by the method of supplying the sealing mixture. Exist:

mechanical (manual);
electrical;
pneumatic;
battery pistols.

Despite the fact that sealant guns are special mechanisms for construction, both professional lines and types for amateurs (home use) are manufactured. Their main difference is cost and reliability. Household varieties break much faster, but they are cheaper. And those that are produced for professional use are always focused on durability.

Skeleton type pistol

The most basic and cheapest type of dispenser is the skeletal one. Such pistols are always manual (mechanical) and easy to use, but their use requires some physical effort. Intended exclusively for sealants in solid tubes with a movable bottom. The movement of the sealant occurs through the pressure of the advancing rod.

A skeleton pistol is made from steel. This indicates its reliability and long service life. There are simple and reinforced skeletal structures. In terms of components they are identical. The only difference is that in the reinforced model the parts have a significant thickness of steel, which means they are less likely to break.

Important! The heavy-duty skeleton caulking gun requires more grip in the palm of your hand when operating, so it may not be suitable for everyone. You should try it in the store before purchasing!

Working with a skeleton caulk gun

Half body sealant gun

Cylindrical or half-body caulk guns have a solid bottom (where the tube is inserted). Thus, the tube with the mixture is positioned more securely, does not warp even during operation, and the rod never jams when the piston moves.

This device is recommended for household use. It is simple, rarely breaks, and much easier to use than a skeletal one. It's more comfortable to hold and easier to pull the trigger. And if you buy a model good quality, then the service life will be unlimited.

Closed caulk gun

If the composition for the job is made independently, and not purchased separately in tubes, then a closed sealant gun is used. Such mechanisms can be professional or semi-professional. They are equipped with a special pipe into which the prepared mixture is poured. Then the pipe is closed and used for its intended purpose.

Air sealant gun

On sale, it is the pneumatic sealant gun that is in greatest demand. The main advantage is ease of use. To use this pistol you do not need to exert much physical effort.

Important! A pneumatic sealant gun can have a housing. These types are made for refilling formulations diluted independently.

The case of this design is usually metal, which ensures reliability. A tube with a sealing mixture is inserted into it, and both plastic and soft tubes can be inserted into this type of gun - the functionality does not change.

The operating principle is based on the displacement of compressed air. And thanks to the pressure and flow regulator, you can control the amount of mixture squeezed out during operation.

Battery gun

The cordless caulking gun is designed more for professional activity. It is rarely used in everyday life due to its high price and some operational features. The fact is that in such models it is possible to configure operating parameters (quantity, speed of the supplied mixture) in order to make it easier to use the device. However, in everyday life this is not particularly necessary and only raises additional questions and delays work, but for construction, on the contrary, it expands possibilities.

This gun runs on a battery that can be recharged. The design has a comfortable handle and trigger mechanism. The base is iron, but the handle, for example, may have a plastic body. The cordless gun is suitable for sealant in hard and soft tubes or for filling a diluted mixture yourself. The kit may come with several attachments (if not, you can buy them separately), there is also a battery, a charging device, and instructions.

Professional devices

Electric sealant guns are professional devices that are not so easy to find on sale. They are purchased by builders for long-term use for their intended purpose. It can be immediately noted that in terms of reliability they have no equal. They operate on electricity, but otherwise are similar to the battery type.

How to insert sealant into the gun?

Before using a construction sealant gun for its intended purpose, it is necessary to put the sealant into this simple structure. So how do you insert caulk into the gun? Full instructions are described point by point below.

Preparing the sealant.

Cuts with a knife top part safety valve (threaded) at the front of the cylinder. Then the applicator is screwed onto the thread (it is always included with the sealant package).

In each individual case, it may be necessary for the sealant to come out in a thin or thick strip. This point is easy to adjust. The tip of the tube tip is simply cut off higher (where the thin part is) or lower (where the tube flares out). Always cut it at an angle of 45 degrees!

Preparing the pistol.

In order for the sealant to fit into the gun, you need to make room for it. The rod with the piston is simply pulled up, pressing on the fuse (spring plate).

Installation of sealant.

When the gun is prepared, then the sealant is installed in it. For many, this causes difficulties the first time, because the pipe with sealant is larger (if you take into account the tip) than the space allocated for it in the gun. But there is one trick here - the sealant is always installed with the spout facing forward. In other words, the plastic packaging is directed into the hole in the end of the gun body. This way, the entire barrel fits completely into the gun without much effort.

If a casing gun is used, then the package of sealant is simply placed inside and secured with a threaded tip. Soft-pack sealant is used in much the same way. One of the wire plugs is cut and placed in the body gun. Then screw on the applicator and use it for its intended purpose. If you make the composition yourself, then you need to pour it into the body of a closed sealant gun and screw on the spout.

How to use a caulk gun?

To use a professional caulk gun or a simple one, you must first press the safety catch to move the stem until the valve stops in the movable bottom of the caulk. By pressing the trigger of the gun a couple of times, you can notice that the working composition is moving and compacting in the barrel.

Now you need to direct the sealant nozzle to where you want to lay the compound. The amount of sealant that will come out of the spout is regulated by the force of pressure on the trigger.

Interesting! Beginners who have not used such devices before should first experiment on any surface.

To understand how much pressure and speed is needed to make a thin or thick straight line of sealant, and how much is needed to fill certain cracks, you need to practice. In addition, to different types pistols need to adapt. Depending on the type, more or less effort is required to use the mechanism, so practice will never be superfluous.

Brands and cost

A construction sealant gun can have different prices. It depends on the type, brand, country of manufacture, so there are many options.

« Makita "- Japanese brand. A semi-professional battery-powered, closed-type version will cost $350-365. Its weight is approximately 2.3 kg, the volume of mixtures is 600 ml.
« Soudal “- a professional closed-type pistol will cost 150-167 dollars. It is also designed to hold up to 600 ml.
« PC-COX " - English brand. Her pistol, called the Powerflow Comb, has a 600ml capacity and a clear body for convenience, and is priced at $45-$55. However, all attachments for it and some other components must be purchased separately. If you add up these details, the total price will reach 150-160 dollars.

But these are all professional and semi-professional models. For household needs, you can purchase budget, simple options.

« SPARTA » used for tubes up to 310 ml. Price 1.2-1.5 dollars.
« Hilti » is a company from Liechtenstein. Makes professional, semi-professional and household models. A half-body DSC for the CP 620 costs up to $100. HDM line from $35 to $100. And case-based CFS-DISPs cost about $50.
« Bison » – simple, but famous brand, makes good 310 ml half-body caulk guns priced under $3.
« BIBER » – a skeleton option priced at about $3.5. A semi-hulled model will cost $5.5.
« WolfCraft " is a German brand. There are many options for their products, but for example, a semi-body, mechanical pistol with a volume of 310 ml will cost up to $15.

The KRAFTOOL, HAMMER and STAYER trademarks are expensive sealant guns used for household needs. Their main advantage is the strength and durability of the structure. But such a tool will cost 10-20 dollars.

As you know, a device designed to work with sealant is called an applicator and has appearance, similar to a pistol or syringe. All instruments are divided into amateur and professional. In any case, despite the intensity of their use, this is either a mechanical device or its pneumatic modification.

Types of sealant guns

Household pistols for home use are exclusively mechanical, and their design is different, since this affects the service life of the tool. For sealant packaged in foil, use a cylindrical gun. If it is located in a cartridge, then it can be applied using a pressure gun, which is structurally designed like a large syringe. If you purchased the sealant in a bucket, then you do not need a gun; it is enough to have a spatula or trowel for the job.

There are several types of pistols:
manual with a cylindrical body;
manual skeleton;
pneumatic.

Manual with a cylindrical body is the cheapest and short-lived; it breaks after using one or two tubes. It is extremely inconvenient to work - the rod moves poorly, the cartridge tries to “escape”.

A manual skeleton gun costs a little more, it is more comfortable to use and more durable, and the rod moves smoothly without distortions. The most reliable and convenient is a tubular gun (syringe). In it, the sealant is ideally located inside, there is no movement, and the rod moves easily and freely. This design can work with sealants contained in bags.

Pistols are divided according to the type of cartridge compartments, and are classified into sheet and frame. It should be noted here that sheet guns fix the cartridge body worse than frame guns. Before purchasing, it is important to determine how easy and comfortable the pistol is in your hand. It is advisable to make several clicks on trigger, feel whether the brushes are comfortable to use. Separately, it is worth paying attention to reliability; as experience shows, models with handles and a trigger lever made of molded aluminum are lightweight and quite durable.

The pressure screw is the simplest device for squeezing out sealant.
Non-reverse pressure guns are most often used professionally. It is more convenient to work with this tool because the piston moves exclusively in one direction forward until the sealant runs out. But when you know in advance that a small amount of sealant will be needed or you know about a break in work, then you need to use a gun with a reverse stroke, which allows you to stop squeezing out the sealant at a certain stage of the work. In this case, after completing a small job, the cartridge is removed from the compartment, the tip is closed and stored until the next use. You should also pay attention to the expiration date of the material; often expired sealants are the cause of leakage in the filled joint.

Professional guns include pneumatic and cordless tools. The time between failures of these devices is long and lasts several years. Air guns operate using compressed air and are driven by a trigger. Many models are equipped with a pressure regulator. The most expensive gun is a battery-powered one, which has the ability to adjust both the pressure and the rate of supply of sealant. This model is very easy to use; you just need to release the handle and the sealant flow starts immediately. It is universal, suitable for both tubes and bags.

How to use a caulk gun

Not many of our compatriots know how to use this tool. Let's learn how to properly use a caulking gun. To begin with, it is enough to have a cylinder or cartridge, as well as the gun itself, which consists of three main parts: a frame, a pusher and a trigger. So, the sequence of actions is as follows:
1. pull out the pusher as far as it will go;
2. take the sealant, cut off the plastic tip on which the markings are indicated;
3. pierce the membrane, which is located under the plastic cap, with a suitable object;
4. securely insert the tip into the intended hole;
5. press the latch, pushing the pusher all the way into the hole in the bottom of the cylinder.

When using a “syringe” gun, you need to unscrew the ring into which the spout is inserted, then remove the inner insert and place the spout in the desired place. By pressing the compensation lever, we pull out the rod as much as possible. After this, cut off the metal ring from the bag and screw the ring onto the spout. Upon completion of work with the gun, it must be rinsed with warm water.

And finally, a few nuances in working with a pistol.

How to apply sealant efficiently?

To ensure that the seam is even, you should use the following recommendations. It is better to cut the top of the cap of a tube with sealant using a stationery knife at an angle of 45°, so that the diameter of the resulting hole coincides with actual size seam Next, lightly press the trigger so that droplets of silicone appear from the hole in the tube. To apply the sealant evenly, it is necessary to hold the gun at the same distance from the wall. Filling should not be done quickly so that you do not end up with broken strips with air bubbles inside. The creation of a beautiful seam occurs thanks to masking tape glued to both sides of the gap, which is removed immediately after applying the sealant along with its excess.

There is another way to perform a high-quality, especially fillet weld. To do this, you need to carefully moisten the side surfaces with soapy water. It is necessary to prepare a wooden or plastic stick in advance, one side of which is cut off in such a way as to set the shape of the future seam. In this case, the final formation of the upper part of the seam is created not by the nose of the tube, but by the passage of the above stick along it. If it happens that you squeeze out excess sealant, then it’s not at all scary; after drying the seam with a hairdryer, you can remove all the remaining sealant from the side surface with the same stick washed in soapy water.

To distribute the sealant evenly and accurately, you can use a device called a gun. Proper Use the mounting gun not only increases the capabilities, but also the economical consumption of the substance. In this article we will examine the issue of proper use of a sealant gun.

Peculiarities

The sealant gun got its name because of the similar principle of operation to the prototype. In addition, this tool looks like a real pistol. The guide imitates the barrel of a weapon. There is also a special device called a trigger. There is also a comfortable handle.

The tool is focused on the ability to squeeze out the silicone substance from the tube, which usually comes in a cylindrical shape, or other packaging. Main difference with others mounting guns in its design. For example, a power mechanism is not necessarily present. Caulk tools come in a variety of varieties, but those that have a manual mechanism are just as effective as automated ones. Automated models are considered professional. For household use, they are more convenient when you need to seal a lot of small seams.

The design of the sealant tool is divided into types. However, a pusher, a compartment for a tube, and a holder are present in any product. Let's take a closer look at the features of household models that are equipped with manual mechanisms.

Since substances are mainly sold in tubes, a manual sealant gun is manufactured in such a way that this particular packaging option is suitable. A special feature of the tool is its movable bottom. It moves easily along the body of the product. The tip of the mechanism is universal, allowing you to place a variety of attachments inside. These parts give the extruded substance the desired shape.

The bottom of the gun moves due to the action of the piston. This mechanism is set in motion when the trigger is pulled. The pusher applies pressure to the bottom of the container, which causes the substance to move and be squeezed out through the nozzle. This pistol format is considered universal, and therefore can be used with different substances.

Types of pistols

The variety of sealant tools is great.

As mentioned above, the easiest way is to divide products into two large categories:

professional;
amateur.

The main feature of professional devices is versatility. Professional pistols come with numerous attachments. They allow the use of various types of sealants.

Amateur models are distinguished by a variety of types and reasonable prices. This group includes many varieties. The products are easy to use. Let us examine in more detail the types of pistols included in the first and second groups.

The group of professional models includes pneumatic and battery types. A closed-type pneumatic version that operates in the presence of a source of compressed oxygen, such as a compressor. Thanks to the supply of oxygen and by pulling the trigger, the required pressure is achieved. The mechanism promotes smoothness and continuity of incoming material. Pneumatic tools are characterized by high performance and continuous supply of consumables.

Continuity is ensured by the oxygen pressure regulator. You need to work quickly with an air gun. Therefore, without the proper skill, its use is unlikely to be convenient. However, the tool is reliable, as it is most often equipped with a metal body that fits various containers. The closed version does not need to be refilled; the empty container just needs to be replaced with a new one.

The device has positive and negative characteristics.

Positive:

multitasking;
comfortable;
aesthetics and accuracy of the applied sealant;
duration of operation period.

Main disadvantage air gun– attachment to the compressor.

A cordless sealant tool is a specialized power tool. The tool is characterized by high performance, safety and efficiency. The operating principle of the tool is similar to piston types. The only difference is that the force on the piston is created using an electric motor. The piston presses on the container or cartridge containing the sealing compound. The optimal operating speed of the device is selected by a switch, and the force is developed sufficiently to squeeze out the required amount of mixture.

The main advantage of the guns is the automatic variation of the amount of sealant supplied. Possible speed change - up to 7 modes.

The main advantages of the automatic tool:

seam uniformity;
dosed supply of the mixture;
saving the effort of the operator who performs the work;
independence from additional stationary devices.

Such advantages make it possible to carry out work in any hard-to-reach places with minimal consumption of mixtures. If the device's battery is powerful, the working time will last for a long time.

Negative quality is that it is important to choose the right adhesive sealing composition. For example, some substances are toxic or flammable and may ignite, which is unsafe for the operator.

The cost of battery pistols is quite high. There is an opportunity to save money if you purchase products in online stores. Various models from many companies are presented here.

The models included in the amateur group of devices have an acceptable price. For example, an ideal option for various types of mixtures is a skeleton gun. The model is durable and inexpensive. The tube with sealant fits perfectly into the structure made of rigid ribs. The piston rod provides a smooth, dosed supply of the substance.

The skeleton of the product is made of thin but high-quality steel. The rod is a faceted rod, which is also made of steel.

The skeletal version on sale is presented in a reinforced form, the design of which is similar to the prototype. The only difference is in more durable and reliable materials.

Half-frame pistols can be found on sale. They are inexpensive but unreliable. The design is almost one-time use for one tube of mixture. The tool often deteriorates with little effort.

The pistol with a cylindrical body is easy to use. In conjunction with the tool, bulk sealants can be used. This option is also ideal if silicone sealants in tubes are used. Any instrument requires preliminary preparation. This stage, however, like the production stage, requires knowledge and skills. Let's look at the features of using different types of pistols in more detail.

How to use?

To properly apply glue using a gun, the substance must be suitable for the tool used. For household purposes, a syringe or tubular gun is more often used for substances sold in tubes.

The material is packaged in tightly sealed packages, so one end must be carefully cut off from the container. The tube is equipped with a special cone, but it is usually sealed. This soldering from the tip of the cone needs to be opened. The cut should be slightly smaller than the required seam size. It is convenient to remove the soldering with a stationery knife. The cut will be correct if it is made at an angle of 45 degrees.

The prepared container must be inserted into the gun, and the cut part must be inserted into the tip of the gun. Remove the rod by pressing on the lever. You need to install the prepared cartridge in the free space. In order to place the container in place in the skeleton, apply several pressures on the lever. That's it - you can use the gun. After use, the used tube must be removed from the tool, and the gun itself must be rinsed thoroughly. The instructions suggest using ordinary warm water for these purposes.

The cordless tool works slightly differently than the manual version. It is enough to charge the cylinder with the existing mounting adhesive. The feed can be adjusted by pressing the trigger.

The cartridge cone must be inserted exactly into the place where the glue is applied. Pull the trigger to activate the piston. Installation with an acrylic substance involves uniformly applying a “sausage” of the required thickness to the treated area. The surface to be treated must be grease-free; do not forget to wear gloves before starting work.

If there is sealant left in the tube after finishing work, it may reuse, you just need to put on the tip and close the packaging tightly. If during work the sealant sticks to your finger, you need to put your finger in a container with a soap solution and apply the same solution to the seam.

You will learn more about how to properly use a sealant gun in the video.

Not many novice remodelers know how to use a caulk gun.

And for some, this tool may seem like a very complex device.

But it does not require any special knowledge and is quite simple to operate.

To start working with sealant, you only need to have a container with the appropriate material and a gun.

The design of the pistol itself is simple. It has a trigger, a frame and a metal pusher. To insert a bottle of sealant into the tool, you must perform the following steps.

If you look at the pusher, you can see a metal retainer (plate with a spring) on the trigger side.

You need to press this lock, and then pull the pusher out to the maximum possible distance.

Then you need to take a bottle of sealant and cut off the tip from it, taking into account the markings. You also need to pierce the membrane under the plastic cap.

When inserting a balloon into the gun, you first need to insert the tip into the hole on it. Then you need to press the latch again and push the pusher into the hole at the bottom of the cylinder until it stops.

Actually, all this must be done to start using the tool. To squeeze out the sealant, you must gently press the trigger of the gun.

Construction stores now have quite a large selection of sealant guns. First of all, the price of this type of tool depends on its functionality.

What types of sealant guns are there?

Sealant guns come in closed and open types. They all have a piston for extrusion and are made to fit different tube diameters.

All kinds of sealants are very common in modern construction. They are used almost everywhere and are made from various substances.

The scope of application of sealants is not limited only to hydro-, noise-, and thermal insulation.

Sealants, depending on the composition, are used to seal seams between logs, in bathrooms, kitchens, etc.

Sealants are also used to seal the seams between panels used to construct residential and non-residential buildings.

The sealant is usually packaged in a special metal or plastic tube (cartridge). In tubes, the sealing compound may be under pressure.

When there is no excess pressure in the housing, the sealant is squeezed out of the tube by the piston.

How to use a sealant gun: types and application features

For novice builders, it may be a discovery that there is no need to suffer so much at all, since there are many simple devices for these purposes - quite peaceful pistols. By the way, there are also pneumatic and even electric models. You just need to know how to use a caulk gun.

Pistol models

How to use the right silicone sealant

The principle of its operation is to squeeze the sealant out of the appropriate container. But, as in any business, there are subtleties here. Let's start with the fact that their range is so wide that everyone can choose one according to their financial capabilities, but how not to make a mistake.

Devices for sealing materials are divided according to the following indicators:

type of compartments for tubes;
design features;
material supply system.

Based on the type of compartments, they are divided into sheet and frame, and the latter are more in demand, since they hold the tube much more tightly.

According to the sealant supply system, the gun comes in several types - each with its own pros and cons.

Mechanical manual

This model is the most affordable option for a tool, although, unfortunately, it is not very durable.

They are great for household jobs when you only need a couple of cartridges. But imagine what it would be like to squeeze out masses using only the physical force of your hands on a large object.

Pneumatic

The gun works thanks to compressed air pressure (3–6 atm). This model is very common when performing medium-sized construction work, since using a gun of this type is quite simple.

This is facilitated by various limiters and regulators that manufacturers equip them with. A pneumatic tool allows you to obtain an even seam of sealing compound of the required thickness. The tool is equipped with a special valve through which excess material is discharged, that is, there is virtually no loss of sealant.

Another advantage is the ability to use it for different containers. Considering that these models operate on compressed air, their body is often made of metal.

Rechargeable

These models are distinguished by their autonomy, since they are equipped with a battery pack, usually lithium-ion. Squeeze out the sealing paste using a handle that is sufficiently sensitive to pressure.

In fact, the speed and accuracy with which the sealant is applied is controlled by the force of pressing the same handle.

Electrical

The electric version and the previous one differ only in the power source - electric ones are powered from the mains.

They provide speed and accuracy, high level savings. They are approached different types containers. You must understand that these professional devices are not cheap, but for simple repairs, in fact, such a model is simply not needed.

Self-contained guns are equipped with a pressure regulator that allows you to regulate the flow of sealing material. Moreover, the “auto-reverse” function eliminates its residual extrusion: when the work is finished, the rod moves back and reduces the pressure.

And finally, according to the characteristics of the device, devices are divided into:

semi-body - works with a tube volume of 310 ml, they have a simple mechanism of a rod and a stand for the cartridge, so they break down quite quickly - they are only enough for 2-3 tubes.
This type of tool is not convenient enough to operate - it is difficult to hold in your hands;
skeletal - designed for work with the same volume, but has a more complex mechanism, consisting of a rod and three stiffeners.
They are more expensive than semi-hull ones, but also more durable;
tubular (closed) – more versatile and suitable for working with different volumes of acrylic and silicone compositions, 600–1600 ml, so it needs to be refilled much less often. By design, it consists of a cylinder, which serves as a cartridge, and a rod.

How to use a caulk gun

The most important point is considered proper preparation the spout of the tube - this determines how well the sealant will be applied.

The cutting angle must be 45°; as for the width, it is chosen in accordance with the thickness of the seam.

For those taking their first steps in this field, it is recommended to start with a cut with the smallest diameter, and then increase it as necessary.

Refilling a plastic cartridge

The exit opening on the tube is cut off.
Sometimes it is simply pierced, however, it should be noted that this causes increased resistance to the extruded material.
To fully extend the rod of the device, you must press the latch.
The tube is placed in the gun and the rod is pushed in to the very bottom of the paste package. In this case, the latch is held in a pressed state.
To squeeze out the paste, press the trigger of the device.
If it is necessary to pause work, press the lock again and the rod extends a little back. Thanks to this, pressure on the tube is eliminated, which prevents spontaneous leakage of the paste.
The sealing material is applied by evenly moving the device's nose along the seam until the entire cavity is completely and efficiently filled. As a rule, with proper pruning, this is quite easy to do.
Having completed the work, close the tube spout with the cap intended for this purpose.

How to fill sealing compound in soft packaging

Refilling soft packaging is almost the same as refilling plastic packaging.

Note a few different points.

Unscrew the fixing nut from the top of the instrument tube and remove the spout. If the tool has already been used, it may need to be cleaned.

There is not much choice in how to remove silicone sealant in a dried state.

This can only be decided mechanically, and this is done quite simply.

The tool rod is retracted all the way back until it stops.
The packaging is cut at the top either with a knife or using side cutters, then inserted into the body and the spout and fastening nut are restored in their places.
When stopping work in hand guns, the pressure is relieved by pulling the rod back.
In more advanced models, this happens automatically.

Sealed gun

A caulk gun is a tool that allows you to use a special sealant on any design surface. According to their classification, these pistols are divided into amateurs and professionals. In addition, regardless of the category to which this gun belongs, it can be either manual or pneumatic.

The sealants are then sold in special containers called “tubes.”

These pipes come in standard sizes or gun sizes, which also come with a specific standard. The price of a seal gun depends on the type of tool you are dealing with, which could be:

- R academic skeleton;

- R academically with a cylindrical body;

— N olukorpusnym;

- And pneumatic.

In this article, we will analyze each of these types of guns and finally find out which sealant is better and worse.

Details of seal types

Hand gun. Let's start with one of the most common pistols.

This is very useful with materials such as silicone or medium viscosity sealants for use in construction and renovation. Generally, these guns are used by non-professional construction workers, so they can be safely classified as hobbyist tools.

This tool can greatly facilitate repairs and quickly complete a sufficient most construction process.

Manual pistol with a cylindrical body. This type of gun is used when working with unpainted sealants, as well as when working with pipes.

Typically this gun is made of fairly durable metal or aluminum. Also a fairly common type of weapon used by hobbyists. However, it is often used by specialists because it is very easy and convenient to handle large areas and repair areas.

Fluffy pistol. This refers to a series of sealing gaskets used by professional builders.

One of the features of this type of gun is a reinforced body, as well as a trigger, which significantly increases the reliability of the tool and facilitates the construction process.

Air gun. An absolutely precise professional instrument.

This is only useful for those who are faced with such work on a daily basis that does this in large quantities. Such a gun will help do the job much faster, with much less effort. It is used in almost universal applications, including pipe processing, volumetric sealants and so on.

Select a gasket gun

Now about the pistol you must choose for yourself.

Firstly, prices for a caulk gun can be completely different and actually depend on the type of tool itself. If you need a weapon for specific occasions, choose a few models on a budget and follow the rules below.

First you need to pay attention to the comfort and comfort of the pistol. Take it by the handle and feel if it suits you.

There should not be much tension on the inside of your hand when you pull the trigger. If you like this model of your pistol, we turn to an external review.

A good and high-quality weapon will have parts of light and durable metal - for example, aluminum.

Don't settle for models with plastic parts and fasteners. Most likely, such a pistol will be aborted after a second operation.

Then, if you want to choose a tool, you need to know how to use it properly. First you have to press the gun handle, the rear lever that is also on it.

Once you have made room for the cartridge, you must remove the metal pin. A tube containing a sealed substance is inserted into this room. In addition, the pistol's fright is pressed and supported on the cartridge, after which the tip is cut off and the submachine gun becomes fully operational.

Now when you pull the trigger, the sealant can be easily removed.

Notice the gun holders in the background - if so, how big is it? — Most likely, we will have to abandon such a purchase and draw attention to another model. To select a gun seal that is tight, you should also check for leaks.

If the gun meets the requirements, the seal of the pipe with the substance will not be compromised, otherwise you will have to refuse such a purchase. Buy a seal gun in any store or online - this is the advantage that today's selection is enough.

Remember that a high quality gun cannot be too cheap because it uses high quality materials and modern technologies, which allow it to last a long time.

Therefore, if we sincerely focus on the most budget models, it is not worth it.

A caulk gun is used not only for interior repairs, but also for some exterior work in home construction. This tool got its name because of the peculiarities of its action. The sealant comes out when the trigger is pressed, and therefore the tool is compared to this firearms. But this comparison, of course, is conditional, since the composition is squeezed out by a piston, which moves after the trigger is pulled. Therefore, it is more of a syringe.

Operating principle

We will look at how to use a sealant gun a little later, but now we will find out how it works. Actually, there is nothing complicated about this: under the influence of pressure on the cartridge, the mixture is squeezed out in the form of a strip, the person directs it and achieves the desired effect. The pressure is exerted by the rod, which moves when the trigger is pulled. It is typical that in pneumatic devices the role of the rod is played by air.

Sealant gun operating instructions

First, a little advice. If at the right time the gun is suddenly not at hand, then in order to knock the sealant out of the cartridge, you can use any available tool. For example, a hammer.

To use the gun successfully, follow these steps, which we have illustrated with pictures.

Step 1: Take care of it first personal protection– at a minimum, wear gloves.

Step 2. Next, prepare the surface to apply sealant. In this case, we cannot advise anything specific, since everything depends on the instructions of the cartridge manufacturer. Everything must be written in back side the last one. To remove the previous coating, use a sharp knife or triangular scraper. Remove remaining crumbs with a brush or use a vacuum cleaner.

In addition, the working surface must be degreased.

Step 3: Next, remove the limiters. If we are talking about a half-body or skeleton pistol, then this procedure will happen quickly. First, make sure that the tube does not have a special bottom-limiter. And if it is still present, then remove it.

Step 4. Let's figure out further how to use a sealant gun. Then pull out the rod in the device. To do this, press the lever and remove the part. Place the cartridge in the place that was vacated by the rod and apply a few gentle pressures on the hook to finally strengthen the container.

Note! In most cases, such cones come sealed. And if you also have it sealed, you will have to cut off the end of the cone to form the required seam diameter. It is important that the cut dimensions are smaller than required for the job.

But if you decide to use a tubular or syringe tool for work, then you should use it slightly differently.

Step 1: First, make a hole in the sealant tube. If you are using packaged material or a “sausage”, then cut off one corner/end with extreme care so that the mixture can easily come out of the bag.

Step 2. Next, place the prepared container with the material into the tool itself, but so that it is the cut end of the container that goes to the tip, through which, in fact, the strip of material will be squeezed out.

Step 3. Of course, before this you need to remove the rod - do this in the same way as with a skeletal-type device.

Step 4. Guns are often equipped with several nozzles with such tips. Choose one of them and screw it onto the cylinder. If you notice that there is no hole on it (the tip), then take a utility knife and cut the tip, but strictly at an angle of 45 degrees. Of course, you also have to guess the size of the future hole in order to get a seam of the required diameter.

Be that as it may, if you have a sealant gun on your hands, then you must also have the manufacturer’s instructions. Take the time to familiarize yourself with it, since manufacturers often equip tools with some improvements and developments that are not provided in standard models.

As we have already found out, if the tool is properly equipped, then there should be no difficulties with its operation. And if you installed the cartridge as described in the instructions above, then you have already done half the work. Therefore, all that remains is to slowly press the trigger and apply the mixture to the desired seam. If you have a semi-body or skeletal type tool, it may take a couple of initial clicks for the required amount of material to fill the void in the tip. After this, make only smooth movements.

And if the model is battery-powered or electric, then by pressing the trigger you will regulate the intensity of the material supply. Therefore, if you are picking up a tool for the first time, then first practice in inconspicuous places - for example, seal a seam in the far corner of the room. After a little practice, you can move on to more visible places.

If you need to trim something or insert material into a gap, wet your fingers a little and run them along the surface. Use soapy water for this so that the mixture does not stick to your fingers. By the way, it is with this water that it is most convenient to remove the formed drips.

Note! The sealant does not require additional drying - in the fresh air it will acquire the required strength in just two to three hours.

And one more good tip: after you finish sealing, mandatory Rinse the instrument with warm water.

Go ahead. To make the seam beautiful, use masking tape - stick it on both sides of the gap and remove it immediately after applying the sealant. To make a beautiful and, more importantly, high-quality corner seam, do the following. First, gently wet the side surfaces with soapy water. First prepare a small stick made of plastic or wood; Cut one side of the stick so that you can use it to set the shape for the seam. Accordingly, the final shape of the upper part of the seam will no longer be formed by the tip of the gun, but by the stick mentioned above.

Note! If you accidentally squeeze out too much sealant, don't worry - there's nothing wrong with it. Simply dry the seam with a hairdryer and remove the remaining material from the side surface using the same stick dipped in soapy water.

Basic classifications

Based on the type of compartments for cartridges (that is, containers with the mixture), the tool is divided into two categories:

leafy;
frame

The latter are more popular because they fix the cartridge more securely. Depending on the method of squeezing out the mixture, guns are divided into four more categories.

Finally, according to the design features, pistols can be:

skeletal (designed for cartridges with a volume of 310 milliliters);
half-body (the volume is the same, but the mechanism is simpler; designed for several cartridges, but extremely inconvenient to use);
tubular, working with any cartridges.

Note! The best option is a skeleton pistol. It costs a little more, but is more durable.

But how to choose the right option? Let's get a look.

Features of choosing a sealant gun

The most important criterion is the amount of future work. If you only need to process a couple of joints, you can safely purchase a skeletal tool. And if you have a more complex task ahead (such as, for example, repairing an entire home), then buy a tubular-type pneumatic tool.

When only accuracy and speed of work are important, the best option is a battery-powered or mains-powered tool. Directly at the time of purchase, see how convenient the gun is for you personally, and whether the elements will interfere with operation.

AND Special attention Pay attention to the hook itself: see if it is fixed tightly enough, what it was made of, etc. Finally, if we talk about specific brands, then, of course, give preference only to trusted manufacturers who have already earned trust.

As you can see, there is nothing complicated about how to use a sealant gun. All you need is the right tool, a quality mixture, a little practice and, of course, a good step-by-step instruction. You have already found the last one - here - so all that remains is to go to the store to buy it.

And finally, another useful video. Good luck with your work!
