When choosing as a heater for walls erected from aerated concrete blocks, foam sheets, the walls should be well cleaned of all kinds of pollution and dust, as well as to leve them. Foam is glued using special glue. For this, a toothed spatula is used. Then the foam is applied to the wall without significant efforts and fixed in addition, using plastic dowels (dowel-zones), which have a very wide hat.
Glue should be applied to the foam and the wall. This should be done when the blocks have any irregularities, since the glue will act as a leveling composition. In addition, it is worth smearing it and the joints that are between the sheets of foam. Sheets of insulation must be fixed with displacement. After gluing them, you can already perform plastering and staining the surface of the walls.
And when choosing mineral wool, it is worth removing pollution from the walls. It is also “planted” on a special glue and fixed on the wall using dowel-zone. Minvata sheets are fixed in a run. On top of them, a mesh made of fiberglass is attached with the same adhesive composition, which will help further avoid the appearance of cracks on the paint and plaster. Next, another layer of glue is applied. After drying it, you can already perform the final finish. Often, vapor -permeable plaster and paint is used for this. Do not warm aerated concrete walls only in the southern regions.
