Nowadays, the building materials market is so diverse that everyone will find what they need, both in quality and price. One of the most used materials in construction is sealant. With it, you can protect the joints between materials from moisture, as well as eliminate some defects. The only problem of the sealant is the difficulty in removing it from the tube without special equipment. In this article we will explain how to use a gun for sealant. Using this tool will increase the speed of work and make it more enjoyable.
No matter what type of gun, the basic device is the same for everyone. It has a body, a stem, through which the sealant is squeezed out, a trigger and a retainer that holds the stem. The task of the work is to squeeze the contents out of the package. This process is very simple: you pull the trigger, which, in turn, drives the rod. Next comes the pressing of the rod to the bottom of the package with a sealant, which serves as a piston, and it easily comes out.
Types and classification of guns
Guns for sealant are divided into several parameters: appearance, complexity of the structure of the body, the method of filing a hermetic substance.
|By design features|
|Semi-hull||Semi-hull - they are not designed for long-term use. Such pistols are suitable for small household work, they are not very durable in operation and are relatively inexpensive.|
|Skeletal||Skeleton pistols, like semi-body guns, cope with same scope of work. They differ in the fact that the skeleton gun is more convenient to use. It consists of two ribs and a stem, which allows a tube with a sealant to firmly fix in it, as a result of which the quality of work will be better. The cost of a skeletal pistol is higher than a semi-corps gun, but it will also last longer.|
|Case||Case Guns are intended for those who are engaged in repair or construction works quite often. They differ in their versatility, they can be used both for sealant in solid tubes, and for sealant in soft packaging. Their cost is higher than all the others, but due to the fact that the consumption of sealant with a body gun is minimal, it is considered more profitable.|
|By way of supplying sealant|
|Mechanical||Mechanical is the most affordable option. Supply of sealant in such pistols occurs only at the expense of physical strength of the hands. Mechanical pistols are purchased for small household purposes.|
|Pneumatic||Pneumatic - used with an average amount of work. Its principle of operation is such that the sealant exits due to the pressure of compressed air. In the gun of this type there is a special valve that allows you to dump the excess sealant and minimize its loss.|
|Electric||Electrical - allow you to make a more even joint and reduce time performance of work. But to use them requires an appropriate experience. In addition, the cost of such a gun, compared with mechanical and pneumatic, much higher.|
When choosing which gun to buy, you need to build on how often you are going to use it and what your financial capabilities are.
Installing sealant in the skeletal gun
No matter what type of sealant gun you choose, the instructions for use are the same for everyone. So, how to properly prepare the gun to work? Let us consider each stage in turn:
For a soft package, only a body gun is suitable
When using a sealant in a soft package, choose only case guns. The scheme for use is simple:
Using a gun for sealant
There are several rules for using a gun for sealant:
After work is finished, the spout of the packaging is cleaned of sealant residues and closed with a special cap. Thus, you protect the sealant from drying out. In a closed form, without losing its qualities, the sealant may last for about three months. The gun itself is also wiped. If this is not done, the gun can quickly become unusable. The metal case is cleaned with a special solvent for the metal. Plastic surfaces are wiped with soapy water.
Do not forget to ventilate the room well where you do repairs.
Given the above tips and advice, you can easily perform all the work associated with sealing, without resorting to paid services of construction companies.
