The gun for mounting foam is an important detail in repair work related to sealing joints and cracks.
It is quite difficult to do without a gun for mounting foam. Getting to many work surfaces while performing repairs will be almost impossible, and this, in turn, will significantly reduce the quality of work.
The foam mounting gun must consist of metal parts.

Rules for using a pistol.
1) Shake the container thoroughly for 20-30 seconds to mix the components.
2) Screw it to the gun (on the adapter) before the hissing sound. The balloon should be located upside down.
3) Turn the adjustment screw counterclockwise by a quarter turn and pull the trigger. Make a "test shot" achieving a normal foam consistency.
4) Clean the treated surface thoroughly and be sure to moisten it with water for better curing of polyurethane.
5) Bring the barrel to the seam, pull the trigger and apply foam inside the opening working in layers. In this case, the tip must be completely immersed in foam.
6) The volume of the exiting foam is regulated by the stroke of the trigger.
7) After finishing the work, the bolt of the flow regulator should be completely blocked.
It is not necessary to remove the balloon if there is mounting foam left in it. In this form, the gun can be stored for several weeks. With long breaks in operation, it is recommended to clean the gun with a special cleaner.
Barrel length
The choice of the length of the gun barrel is limited to three standard ranges:
* from 10 to 15 cm - used for working with easily accessible surfaces;
• from 15 to 20 cm - universal gun for all types of work;
* over 20 cm is a highly specialized tool for sealing hard-to-reach surfaces.
