Read the Label - CrownPrep

CrownPrep is a water-based acrylic conditioner. It conditions and consolidates nearly all porous cement/mortar crown washes prior to application of products such as CrownSeal and CrownCoat. It improves durability and adhesion of repair coatings by up to 200%(ASTM D7234).


Weather Conditions: 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.

Surface Preparation: Surface to be conditioned must be structurally sound, not loose. Surface must be clean and dry. Chimney crowns should be properly cleaned with a wire brush and swept to remove dust before using CrownPrep in order to consolidate soft, sandy mortar crowns. Protect roof and masonry from inadvertent spills.

Application: Stir before use. Apply two liberal coats of CrownPrep wet-on-wet to the entire crown with a paint brush. Then apply CrownSeal or CrownCoat as per label instructions.

Note: No need to mist crown with water before application of crown repair product.

Drying time: No drying time needed. Crown can be coated with either CrownSeal or CrownCoat within minutes after applying CrownPrep.

Coverage: 100-150 sq ft (10-15 average chimney crowns) per half gallon depending on surface texture and porosity.

CLEAN UP: Wipe up inadvertent spills and drips on non-target surfaces immediately with a clean damp rag. Rinse brushes with soap and water before product dries.


Keep out of reach of children. With adequate ventilation, respiratory protection is not generally required during normal use and handling. The use of protective gloves and chemical splash goggles is recommended. Wash thoroughly after handling. Keep from freezing. See SDS for additional information.

FIRST AID: If inhaled: In all cases of doubt, or when symptoms persist, seek medical advice. Move the affected person away from the contaminated area and into the fresh air. Ensure fresh air breathing. Allow the victim to rest.
If swallowed: Rinse mouth and drink water; never give anything by mouth to an unconscious person. Obtain emergency medical attention. Do NOT induce vomiting unless directed to do so by a physician.
For skin contact: Remove affected clothing and wash all exposed skin area with mild soap and water, followed by warm water rinse. If skin irritation occurs, get medical advice/attention. Wash contaminated clothing before reuse.
For eye contact: Immediately flush eyes thoroughly with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If irritation persists, seek medical attention.
