A concrete mounting gun is a special tool designed for fastening various structures, parts and elements to monolithic concrete surfaces. The device offers a fairly broad functionality, different types of action, and can work not only with concrete, but also reinforced concrete (even with high-density reinforcement), cinder block, brick, etc.
Thanks to the use of a mounting gun, you can significantly reduce the time and effort required to complete the task, especially when it comes to impressive volumes of work.
The construction gun for concrete allows you to quickly and reliably fasten various equipment (ventilation, plumbing, electrical, etc.), hydro/sound/heat insulating, wall and finishing, roofing materials using dowel-nails.
A dowel gun for concrete makes it possible to significantly increase installation productivity and does not require pre-drilling of fasteners. Typically, pistols are produced quite massive (up to 5 kilograms) in order to increase the efficiency of the process. According to the principle of operation, a concrete gun can be gas, pneumatic, powder, electric, etc.
You can use the tool in the most inaccessible places; you should choose it in accordance with the volume of intended work, operating conditions, requirements and current characteristics.
Device characteristics
Depending on the model, the properties and performance of construction guns for dowels may vary, but they also have parameters common to all:
- manual or semi-automatic method of feeding the cartridge;
- weight of a loaded pistol - 3.1−5 kg;
- electric, powder, battery or gas powered;
- single-charge or multi-charge device for supplying elements for fixation;
- device length - 345−475 mm;
- trunk diameter - 8.2−12.5 mm;
- operating temperature range - from -31 to +53 ° C.
Choosing a compressor for a nailer
To operate, a pneumatic nailer requires a compressor, and this device must be purchased separately. When purchasing a nail gun, it is recommended that you carefully study its instructions and find out if the tool has specific requirements for the air blower.
It is better to choose a compact compressor for a nailer so as not to weigh down the structure.
Most often, nailers work with compressors up to 8 bar. Such units provide sufficient performance, but at the same time they cost quite moderately and do not look very bulky.
Areas of use
Nailers are used in construction for driving dowels, studs, nails and pins into various types of surfaces. It is mainly used for working with surfaces based on:
- plastic;
- concrete;
- natural and artificial stone;
- wood;
- ceramic and silicate bricks.
This tool is suitable for voluminous work involving repeated repetition of monotonous actions.
The dowel gun is used for the following purposes:
- Laying communications in the interior of the building. The speed of driving in elements for fasteners directly affects the quality of installation. If the clamps are installed slowly, they may become skewed. This will lead to a decrease in the functioning of Internet cables, antenna wires and the electrical network during their operation. Quick fastening of dowels using a nailer guarantees precise and even fixation of the elements. To achieve the optimal result, it is necessary to carry out the markings and calculations correctly.
- Siding covering the facade of a building. Decorative finishing involves fastening a large number of elements to the walls with nails.
- Installation of soft roofing. This process requires uniform and high-quality fastening of all elements, which is quite difficult to do manually. The adjustment system in the mounting gun allows for optimized work.

Gas mounting gun for dowels - disadvantages
And yet, a gas nailer cannot be called ideal. Craftsmen working with it will also have to put up with some disadvantages. The first thing that catches your eye is the presence of exhaust gases, which you should not breathe at all, so the room in which the work is carried out must be well ventilated. The combustion chamber periodically needs to be cleaned of carbon deposits and soot.
Compared to an air pistol, models powered by gas are still larger in size, and the price of a shot is more expensive. The cost of a gas installation nail gun can be several times higher than analogues with another drive. However, this price is justified by its versatility, because it’s not for nothing that gas and powder devices are classified as professional.
Features of operation
Dowel-nails used in construction guns differ from conventional fasteners in their special configuration and structure. They are a nail with a washer located at the tip, which ensures a tight connection between the fastener and the surface.
To obtain a high-quality result, you need to understand how to use a construction gun correctly. The tool is used as follows:
- the place where the dowel will be located is preliminarily outlined;
- the charged device is brought close to the surface and a shot is fired;
- the rod goes deep into the material, the washer moves and fixes at the nail head.
Dowels with porous surfaces cannot be used. The fastener may fall into the material or not securely fasten.

Gas nail gun – advantages
The gas-powered unit has a number of significant advantages over other models powered by pneumatic, powder or electric drives. Obvious advantages are the complete autonomy of the unit from external energy sources. In this regard, only cordless nailers can “compete” with gas models, but they are not enough for such a large number of shots, and the shot force is only sufficient for small fasteners and soft substrates, such as wood, plastic and drywall. The ergonomics of a gas nailer also benefits because it is not tied to an energy source by any hoses or wires, like a pneumatic gun or electric models. This is why roofers prefer gas-powered tools.
