Homogeneous, thin liquid with a milk white color, consisting of a dispersion of acrylic copolymers with a finishing additive. After application to mineral substrates, IsoGrund penetrates deep into the pores and has a hydrophobic effect, solidifies the pore structure and forms a thin film that is very strongly connected to the substrate. This balances the absorbency of the substrate and improves the adhesion of further coatings. Environmentally friendly product with no environmentally harmful effect. Does not contain any organic compounds.


New plaster, concrete and other mineral substrates should be bound and matured. Remove old, loose, brittle and peeling layers with poor plaster adhesion and greasy areas. If the surface requires any repairs, repair defective areas with mineral mortar, depending on the nature of the surface.

Typical substrates that can be primed with IsoGrund: Concrete, aerated concrete, cement plaster, plasterboard, wood, wood-based panels and other absorbent substrates.
