Colourless acrylic and vinyl primer. Intended for all civil-engineering bases. Used for priming absorptive and porous structures both inside and outside. It is widely applied in civil engineering due to its high quality. Through the number of applied layers, we can adjust the base’s absorptivity. It is ideal for gypsum plaster, limestone plaster, frail paints, tiles and plaster finishes. Thanks to the low molecule, the penetrating primer is able to penetrate elevation paints and bind them with the base.
