TIFGRUNT is a water-based dispersion primer for internal and external use. Strengthens the substrate, making it more resistant to abrasion, equalises and lowers the substrate's absorbing capacity. Allows walls to "breathe" - does not form a "film" on the surface. It is used under paints, adhesives, plasters, joints and levelling slurries. The product may be used practically on all mineral substrates - concrete, gas concrete, cement-shavings, cement-lime, gypsum, gypsum-cardboard, etc.
