Description
ChimneySaver CrownPrep is a specialized water-based acrylic conditioner designed to prepare and consolidate porous cement or mortar crown washes. This innovative product ensures superior durability and adhesion for repair coatings like CrownSeal and CrownCoat, delivering long-lasting results for your chimney repairs.
Masonry chimney crowns are often constructed with mortar rather than the recommended concrete. Mortar-based crowns tend to have sandy, porous surfaces that trap dust and organic matter, which can compromise the performance of repair products. CrownPrep addresses this issue by conditioning the surface, making it ideal for the application of water-based, mastic-type repair coatings.
Key Benefits:
- Prepares & Consolidates Existing Crowns
- Improves Adhesion & Durability of Repair Coatings
- Easy Brush Application
- Environmentally Friendly Solution

Directions For Use:
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:
Apply two liberal coats of CrownPrep wet-on-wet to the entire crown with a paint brush. Wait 5-10 minutes for CrownPrep to tack-up, 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.Technical Specifications
