It is used for priming the substrate before applying plaster in silicone and silicone-acrylic, inside and outside the building. It is used for priming the reinforced layer in thermal insulation systems and on other properly prepared mineral substrates (such as: concrete surfaces, cement plasters, cement and lime plasters). The use of a plastering primer improves the adhesion of the mortar and plastering mass to the substrate and facilitates the work during the plastering expedition. It aligns the course of binding and drying of applied plaster. Reduces and unifies absorbency, and reduces the dustiness of the substrate. Protects the primed surface against the harmful effects of moisture. It prevents the transfer of impurities from the primer layers to the plaster and eliminates the possibility of stains. Creates a colored coating on the primed substrate / in colors that match the color of the plaster w /, which reduces the effect of piercing the color of the substrate through the structure of the plaster.
