Primer based on acrylic dispersion with quartz sand and antiseptic additive. Contains adhesion-enhancing additives. Intended for internal and external works: – for priming dense, weakly moisture-absorbing mineral surfaces (monolithic concrete and blocks, silicate bricks and blocks, ceramic bricks and blocks, etc.) before filling, smoothing and decorative thin-layer plastering; – for priming ceramic plates before gluing new plates on old ones; – as a waterproofing primer before gluing ceramic tiles on plasterboard; – for priming floors (concrete, plaster, wood, tiles, etc.) before pouring self-leveling compounds; – for priming oil and alkyd coatings before filling, plastering or gluing tiles and plasterboard. The primer increases the adhesion of dense and non-absorbent surfaces with mineral plasters, fillers, glues, is resistant to the effects of alkalis, water resistant, vapor permeable, does not contain organic solvents. Tinted red.
