For insulation of a raw wall, you can order the implementation of professional thermal insulation in a construction company. The cost of this kind of work is quite high. A more economical option is to protect the room from moisture and cold on its own. The most popular material among home masters is a polystyrene foam is a moisture -proof insulation. This material is sold in rolls having a 5 mm thick, which is easily glued to the surface of the walls and masked with wallpaper or drywall.
You need to calculate the required amount of material in order to insulate the internal walls. Also, do not forget about small gaps (0, 5 cm) between neighboring sheets of polystyrene foam.
Follow the cutting of the panels in advance. In the absence of opportunities for using the machine in order to cut the foam, perform the insulation cutting using a sharp knife or hot nichrome wire. All insulation work must be carried out inside the ventilated room in order to get rid of the unpleasant odor.
You need to prepare the surface of the walls for pasting with polystyrene foam. Clean all pollution and from the old decorative coating. If there is such a need to seal all the cracks using the mounting foam, and hubble all the bumps. You can use a mixture of tile glue with a plaster solution with uniform parts.
The primer of the flat wall must be performed in several layers using the “concrete asset” or “Activation of soil”. Pay close attention to the corners that need to be thoroughly processed by lubricating with an overlap (5-6 cm) adjacent angles.
After which the processed surface must dry. Next, it is necessary to apply a thin layer of several millimeters starting putty. Based on the basis, you can fix the insulation panel using a special adhesive composition for polystyrene foam.
The glue solution must be applied to the side of the panel and press it to the wall surface. Using the force, make ironing cutting cutting using a rubber roller. Each sheet must be applied to the neighboring leaving a gap 2, 5 cm, so that then it will not be a small seam.
Wait until it completely does not dry out the glue according to the instructions from the manufacturer. Next, you need to close the seams using the mounting foam and cut off the excess using a knife.
A thin final layer of putty must be applied to polystyrene foam. After drying it, you can proceed to gluing the walls with vinyl or non -woven wallpaper. With the formation of minor irregularities on the insulated wall, the finishing material will hide these defects.
