Properly seasoned and treated cement and cement-lime plasters, concrete substrates and cement floors. Walls made of ceramic and silicate bricks and blocks as well as of cellular concrete blocks.
Substrate should be clean, stable and sound. New plaster work and concrete should be set and seasoned. Remove loose, peeling and old material of poor adhesion. Any chipped areas should be patched with ALPOL AZ 130 quick setting mortar or ALPOL AZ 135 levelling mortar. Treat the loose substrate with ALPOL AG 700 and ALPOL AG 703 deep penetrating primer to reduce absorption, if necessary
