Very many categories of repair work carried out in enclosed spaces and associated with the installation of such building structures as door and window blocks, provide for the mandatory sealing of the latter. To seal the existing joints, a special tool is used to fill them with assembly foam. In this article, you will be able to get acquainted with how to apply the foam to the interface, in need of reliable sealing.
Before starting work, you must carefully examine the place supposed compaction, and then thoroughly clean it from dust, debris, stains and other contaminants. After cleaning the working area, it should be moistened with water; at the same time you can resort to the help of a spray gun. The fact is that after moistening the articulation surface, the assembly foam interacts with it more actively and increases in volume more quickly.
In addition, before starting work it is recommended to heat the cylinder to plus 20 degrees Celsius, which can be done by simply lowering it into a container with water heated to this temperature.
Each time before pouring foam, it is necessary to vigorously shake the container so that its contents can mix well and acquire the necessary consistency.
In our Days on the market there are two modifications of cylinders with a single component composition used to seal various joints. These are:
Cylinders have a built-in atomizer with a tube for directing the flow of foam. In contrast, professional foam application involves the use of a more complex mechanism - the so-called assembly gun with a special nozzle for the cylinder.
The handling of these devices is as follows:
Filling gaps with polyurethane foam
During the replacement of the used cylinder the installation slot It is recommended to lubricate the pistol with a special compound that removes all foam residues.
Heat insulation of joints with construction foam
Filling of voids with construction foam
In the intervals between gun inserts, the foam bottle should be placed vertically.
