This proprietary water-based acrylic conditioner conditions and consolidates nearly all porous cement/mortar crown washes prior to application of products such as CrownSeal and CrownCoat. CrownPrep is used prior to application of CrownSeal, CrownCoat, and other water-based, mastic-type crown repair products. CrownPrep improves durability and adhesion of repair coatings. Masonry chimney crowns are commonly made with mortar instead of the recommended concrete. The surfaces of chimney crowns made with mortar are generally sandy and porous which often harbor atmospheric dust and organic matter. This product ensures longest lasting results of repair coatings such as CrownSeal and CrownCoat. Note: Surface and air temperature should be a minimum of 45°F but not greater than 95°F at the time of application. Do not apply if temperature is expected to drop below 45°F within a 4-hour period. Do not apply to frozen or frost covered surfaces. Do not apply to wet or water saturated surfaces and/or when rainfall is eminent.
