Porous substrates (mortar, rouge concrete, cement, brick, etc.). It is convenient to apply the first coating as porosity sealer of IMPERMAX diluted with approx. 10%of RAYSTON solvent, and never under direct sun or heat., making special attention so that support is not hot. This priming can be made by roller, extending the product so that it penetrates, saturates, and seals pores. The quantity of product to apply at this stage is approx.0,5 Kg / m2. It is important to wait until this first coat is dry before applying the second coat, also breaking bubbles that may have come up so they do not interfere with the treatment.
