Substrate preparation
The substrate should be stable, load-bearing, dry, grease-free, frost-free, dust-free, free from efflorescence in salt and loose parts. In the case of building insulation with concrete sandwich panels, it is necessary to assess the condition of the texture layer. The putty filling the joints between the boards must not come into contact with polystyrene. The plaster fragments with poor adhesion should be removed and filled with Weber KS112 adhesive mortar. Strongly absorbent and sanded surfaces should be thoroughly cleaned and primed with PG229 deep penetrating weber primer. Smooth surfaces should be thoroughly cleaned and primed with a primer with the addition of PG215 quartz sand Weber.
