Substrate type
Concrete walls or those made of gypsum, ceramic, silicate and cellular concrete components. Gypsum, cement, cement-lime, lime plasters and gypsum boards.
Substrate preparation
The substrate should be clean, stable and sound, not chipped and free from nicks and dust. Remove remains of paint and other contamination. Treat the loose substrate with ALPOL AG 700 deep penetrating primer and ALPOL AG 703 primer for absorbing substrates to additionally reduce absorption, if necessary. Degrease concrete substrates and increase their adhesion with ALPOL AG 702 plaster primer. Protect all steel components (frames, conduits, barriers etc.) from direct contact with gypsum, due to its corrosive action.
