Fastening the foam to the wall: the simplest way
The covering of the walls with polystyrene is carried out in three main ways:
- With the use of dry or wet glue;
- With the use of dowels;
- With the use of dowels and glue, with further finishing with heavy facing materials.
Each of these methods can be used for the insulation of a residential building. The use of an adhesive is actual for internal insulation of living space. Stronger fastening for such purposes is not required, because the finish finish will not have enough weight. Important! The glue must not contain parts of the solvent, which can damage the insulation material.
Doors are most often used for ceiling work, where maximum reliability is required. How to fix the foam to the wall using both glue and dowels? This method is considered acceptable for outdoor works, when the insulation will be finished with tiles or an additional layer of plaster.
Bonding the material to the walls
So how to glue the foam on the walls? This type of installation allows not only to insulate the living area, but also to level out small wall irregularities. As a rule, special dry glue or gypsum plaster is used for interior works. But before the walls are covered with foam plastic with the use of dry mixes, the wall surface must be prepared in a qualitative way, which is necessary for maximum adhesion to the material.
Important! Pasting walls with foam means the relative evenness of the rough surface of the wall, because this will affect the finish of the room.
The most optimal sticking of foam on the walls is done with polyurethane foam in the mounting bottles. With this composition it is possible to fix the insulation material on any rough surface with the ultimate speed and quality. It is worth noting that this material has all the qualities to be considered the leading in this field.
Use of polyurethane in mounting
The polyurethane composition allows the master not only to perform assembly work with maximum simplicity and speed, but also to save a certain amount of money. The fact is that the cost of such a composition does not greatly differ from the cost of a simple dry mixture, for the preparation of which it will take additional time and effort.
Important! The use of polyurethane should be accompanied by the use of a rinse aid so that the composition does not dry out at unused time.
Before gluing the foam to the wall, care must be taken to ensure that it is leveled. The main disadvantage of this composition is that it is not able to hide irregularities, as it can be done by using the thickness of the application of dry glue. But this disadvantage is easily not noticed in the total number of positive characteristics.
How to attach the foam to an exterior wall? In this type of installation work, a polyurethane mixture can also be used. This compound is excellent resistance to temperature changes, which is considered the most important requirement for outdoor construction work. In addition, working with this adhesive does not require special skills and tools, because the balloon is fixed in a simple mounting gun, which is available for every master.
