Omega RapidPrime is formulated for use as a priming agent under all Omega textured finishes, coatings, and similar products to promote bond strength, color consistency, and uniform suction, while increasing water-resistance and finish coverage. It offers excellent efflorescence and alkali resistance on cement-based surfaced with a pH up to 13, such as new stucco, concrete, and masonry. With its high alkali resistance, RapidPrime can be applied without having to wait for the cement-based substrate to drop in pH, thus saving time and money.
