In any case, it is essential to achieve a suitable anchoring that the surface to be treated is completely clean and dry, that is, free of dust, grease, oil, plaster, cement or paint stains. If cleaning in an aqueous medium is carried out, it is ESSENTIAL that the surface is dry before applying the coating.
In concrete floors, it is advisable to carry out the preliminary cleaning by mechanical or chemical means, rinsing with plenty of water in both cases and letting it dry.
The product can be applied by brush, roller or spray gun, making it convenient to apply successive layers of little thickness each.
Better results are obtained with three thin layers than with two thick ones, the final amount applied being the same. The average yield obtained is around 3-5 m2 per kg, varying very significantly depending on the porosity of the substrate.
