How to fix expanded polystyrene

Polyfoams including expanded polystyrene, compete to mineral wool for the right to be called the best heater. On the main characteristic – teploizolyatsionnost – they exceed mineral wool, however concede to it on fire safety. As polyfoams sustain combustion, it is extremely desirable that they have been isolated by layers of non-combustible materials, for example, plaster or brickwork. The expanded polystyrene concluded in stone wall is ideal heat insulator.

It is required to you

  • - expanded polystyrene;
  • - primer;
  • - tiled glue;
  • - socle level;
  • - electric drill with set of pobeditovy drills;
  • - mixing nozzle;
  • - dish dowel;
  • - tanks for primer and cultivation of glue;
  • - set of the construction tool (hammer, palettes, rollers and so forth).

Instruction

1. Expanded polystyrene fix to the basis glue and special fasteners – dish dowels (fungi). Clean wall from flows of solution, dirt and dust. Progruntuyte its any primer suitable for this purpose (for example, AS-5 half-imine). If material of wall has the increased absorbency (shlakobeton), progruntuyta wall two times. It will prevent absorption by the moisture basis from glue. Before continuation of works give time to primer to dry.

2. For support of the lower number of plates attach to wall socle levels – the With-shaped profile from perforated metal. The lower edge of level has to coincide with the line of joint of socle with wall. Fastening is carried out by dowels in number of 3 pieces on 1 meter of length of level.

3. Stir glue (polimin P-22, ceresit CT 85 and so forth) in strictly certain amount of water by means of electric drill and mixing nozzle. Some grades of glues demand stirring with break. You carry out this procedure in strict accordance with the instruction.

4. Apply glue on polystyrene foam leaf with strip on its perimeter at distance of 2-3 cm from edge, leaving small admissions for production of air from the central area of plate. In the center of the sheet glue is applied locally, the sizes of the missed the mark sites have to be about 10 cm.

5. Beginning from bottom corner of wall, establish plate by long edge on socle level and densely drive her into the corner. Control vertical position of surface of plates the level or plumb. When laying the second row provide discrepancy (overlapping) of joints in comparison with the first row. Cutting of plates is carried out by long sharp knife.

6. Having established several plates, fix them by dish dowels, previously having drilled openings of such depth that the dowel entered wall not less than on 50 mm. The plate of dowel has to be installed aflush with the surface of heater. It can be provided, striking with the hammer with necessary force plate of dowel or having slightly flattened out plate surface in zone of contact with dowel before its installation.

7. After heater is attached to all wall, apply on its surface adhesive layer with width equal to width of armoring lattice, level it the wide palette. On corners of walls and window openings impose perforated corner on heater edges – for protection of edges of expanded polystyrene from mechanical damages.

8. Impose on adhesive layer armoring lattice and prikatayta its roller. Over grid put and you vyrovnit the palette one more adhesive layer. After all wall is proarmirovana and is missed the mark with glue, give it time to harden then to progruntuyta surface. After primer drying the wall surface will be ready to plastering.
