Substrate type
Reinforced layer with mesh, embedded in adhesive ALPOL AK 527, AK 531, AK 532, AK 533 or AK 534, primed mineral wool in ALPOL TERMO STROP systemand cement and cement-lime plasters, seasoned concrete surfaces, gypsum plasters and gypsum boards.
Substrate preparation
The substrate should be dry, clean, stable, sound (reinforcing layer at least 3 days after embedding mesh in adhesive, plaster – 28 days after application, seasoned concrete). Remove brittle, loose and peeling material with poor adhesion, patch damages with ALPOL AZ 130 quick-setting mortar or ALPOL AZ 135 levelling mortar. Strengthen loose substrates with ALPOL AG 700 deep-penetrating primer. To reduce substrate absorption, if necessary, use primer for absorbing substrates ALPOL AG 704. At least 24 hours before plaster application, treat the substrate with ALPOL AG 701 primer. Pre-primed mineral wool does not require additional treatment.
