Duracoat wood primer
Duracoat Alkali Resistant Primer is a high quality water based acrylic copolymer primer intended for use on masonry surface to minimize unsightly white salts or "efflorescence" migrating through the applied coating system. The primer forms a barrier over alkali substrates limiting the reaction with atmospheric Carbon Dioxide thus reducing the formation of unsightly white deposits or "efflorescence" on the surface typically associated with coating of highly alkaline fresh masonry.
