Surface Preparation&Application

Before the application, foreign substances that prevent adhesion such as dirt, rust, mold oil on the application surface should be removed, plaster and concrete residues and wastes should be cleaned from the application surface. Lower surfaces that are not strong enough to support themselves, such as cracks and weak surfaces, need to be repaired. Cleaning must be performed with pressurized water, a wire brush or sandblasting methods, as appropriate. The surface must be dry and clean. Active leaks and water leaks, if any, should be resolved before application. To improve the adhesion of absorbent surfaces, the surface must be primed with PROF U-AP. PROF W-SF is ready-to-use, requires no thinning, must be mixed in its own bucket with a high speed blender for 5 minutes. Once the mixture is ready, PROF W-SF must be applied to the surface in 2 perpendicular layers using a brush, roller or a suitable sprayer. Wait at least 4 hours between coats. Care should be taken to apply between +5°C and 35°C.
