Insulation of walls with foam plastic at the moment is a very popular way to make living in a house with freezing walls more comfortable, while also lowering the costs associated with heating the home. This operation is performed in several basic stages, each of which is very important.
First you need to prepare the surface. If it is a question of external walls, then there should be only plaster without any decorations. It is necessary to walk on them only with a primer akvastopom. Then the measurement and selection of the necessary materials follows. Here everything is quite simple, you need to measure the height and width of the walls, and then take away from these values the parameters of window and door openings. In addition to polystyrene, corners are also needed to strengthen the corners and their leveling, plastic painting mesh, with which the putty will be reinforced, special dowels that will be required to fix the sheets of foam, they are usually taken at the rate of 6 pieces per square meter.
If we consider the insulation of walls with polystyrene, we should separately touch upon the choice of this material, as well as the glue for it. With glue it is not difficult to determine, it is necessary to buy it with a calculation of 25 kilograms per 3 square meters of surface, and this is calculated that it will be used for gluing and puttying. Next, you need to choose a foam, and here it is important to know that it can be different in density, this determines its cost. For outdoor work, the thickest material is 50 mm thick.
Warming of walls with foam plastic can be called a fairly easy process that does not take too much time. First, mix glue in a container. Then you can apply it to a sheet of foam plastic with a trowel spatula in a uniform layer, and then walk the comb, which will achieve uniform application. On the wall should be similar actions. After that, the foam can be pressed against the wall, it is good to knock on it, this can be done with hands or with a special device. Further, the sheets should be fixed by means of special dowels, with one fastening placed in the center, and the other four in the corners. Similar actions are performed on the entire surface, which should be insulated.
It is worth saying that the insulation of the walls with polystyrene foam does not end there on its own, then follows a more complicated stage - putty. To begin with, it is necessary to glue a metal painting corner to all corners and slopes , since these vulnerabilities require the most active protection, in addition, after such a procedure, puttying will be much easier. You should smear glue on the corner, drown in it a corner, and then align using the rule.
The warming of the walls by oneself at this stage is a little more complicated, since it is necessary to apply a thicker layer of putty than usual, this is done so that it can drown a special reinforcing mesh. Create a smooth and even surface is possible only by applying several layers.
It is worth saying that the insulation of the walls with foam plastic allows you to save up to 30% of the energy that goes to heating, and this is a fairly good indicator.
