This is a water-based, transparent, silicon, ready-to-use interior satin gypsum primer. Pure acrylic resin-based interior primer, which resolves the problems experienced in printing surfaces with high absorbance and dusting property (plaster, satin plaster and plaster of paris) and which can also be used comfortably on all surfaces such as grout, exposed concrete, gas concrete and brick. With its strong binding property and micronized particle structure, it penetrates profoundly in the surfaces, binds the free agents on the surface and creates a robust subsurface with reduced absorbance and higher binding strength for the finishing paint coat. It does not create a film at all. It prevents early drying and decreases paint consumption. Due to the silicon content, it reduces the moisture absorbing property of the surface and increases vapor absorbance. It is odorless and environment-friendly. Recommended for exterior use.
