Yes, SealantPro can be used as a breathable primer for a topical sealer (acrylic, urethane, epoxy, etc.), paint, and adhesives, epoxies or mastics. It is best used with a breathable topical sealant to create an extra layer of protection from clouding and film separation. Likewise, the life of a painted concrete surface is greatly extended by applying SealantPro first—decreasing the eventual separation of paint from a concrete surface caused by excessive moisture working its way through the substrate. The same is true for adhesion of hardwood flooring, carpet, linoleum, tile, backer-board, etc.
Because SealantPro is designed to discourage water and other liquids from penetrating the substrate, it is not an ideal base for concrete stains, many of which are water-based and in fact designed to penetrate the concrete. Some solvent-based stains have been seen to penetrate “enough,” but are not recommended. SealantPro can be applied after hydrophilic concrete stains to prevent fading over time, but is not recommended for use atop hydrophobic stains, as it would not be able to penetrate the surface as it is intended.
