Surface Preparation&Application

The surfaces must be clean, smooth, solid and cleaned from all kinds of dust, oil, dirt, rust, mold oil, detergents and wastes that prevent adhesion. If segregation occurs in concrete, damaged and loose parts should be discarded and weak parts removed. If there are cracks or cavities on the floor or wall where the application will be done, they must be repaired using suitable repair mortars. For the application of the primer, the product PROF W – HP is diluted 1:1 with water (1 measuring cup of PROF W-HP: 2 measuring cups of water) and applied on the surface with a stiff brush. Once the primer is applied, allow to dry for at least two hours. It should be mixed for at least 3 minutes with a low-speed mixer in a clean container free of all kinds of non-adhesive substances or in its own package. For maximum penetration when applying the first layer, it must be applied to dry surfaces with a suitable roller, brush or sprayer. The second layer must be applied about 4 hours later. An additional layer may be required on very porous surfaces to provide maximum protection.
