Cement, cement-lime and lime plasters. Walls made of ceramic and silicate bricks and blocks, cellular concrete blocks and others, concrete surfaces, Styrofoam layer in thermal insulation systems.
For bonding EPS boards
The substrate should be clean, dry, stable and sound. New plaster work and concrete should be set and cured. Remove loose, cracked and brittle plaster and widen the cracks. Patch small pits with ALPOL AZ 130 quick setting or ALPOL AZ 135 levelling mortar, apply ALPOL AT 310 plaster on larger surfaces. Remove contamination and peeling paint from sound plasterwork. Dedust the surfaces. Treat loose substrates with ALPOL AG 700 deep-penetrating primer. If necessary, to reduce the substrate absorption use ALPOL AG 703 or ALPOL AG 708 primer.
For embedding mesh in EPS
Styrofoam surface should be dry, clean, stable and sound. Any gaps between boards should be filled with Styrofoam strips cut to size. Grind the surface with a metal grater or hand sander
