A material used for strengthening porous, absorbent surfaces, suitable for plaster, gypsum, absorbent drywall, concrete, and brick. It deeply penetrates the surface, making it stable and suitable for further painting and decorative work. Before applying the primer, remove crumbling, unstable plaster and dust from the surface. Apply plenty and evenly with a brush or paint roller; once dry, it is ready for decoration. Surfaces treated with deep primer absorb significantly less. Dilution: Not recommended Coverage (depending on surface absorbency): 50-150 ml/m² Available sizes: 150 ml, 500 ml, 1000 ml
