The crown of our chimney was severely damaged by a earthquake three years ago and I didn't think to check the chimney for damage...until two months ago when the rains began pouring into the fireplace. After a thorough inspection and online research I decided on CHIMNEYRX...and it was fabulous. Online purchase was easy...delivery on time...instructions clear and concise...and VERY helpful. Very easy to apply and when completed...looked like a pro. Things I did that might be helpful to others...dip your brush in water and shake excess water before applying material...makes for much smoother application and fewer brush strokes. If product begins to dry upon application...it was nearly 90 degrees and dry when I applied...spray your brush with water spritzer used to moisten chimney crown before applying product...again...makes for superior application with minimal brush strokes. Cleanup was very easy and materials are adhering like a fortress. Haven't had heavy rains to test it thoroughly, but I have NO doubt this product will be the answer to all my problems. To ensure a waterproof chimney, I also sprayed a masonry sealant on the bricks...easy to do and should last for years. Review: Seems to be a good product - Went on easily, the stiff nature of the product meant it went on easier than paint, so no concern about it running or dripping, just didn't have that problem at all. I had a large and very rough chimney crown to seal so my coverage was much less than they advertise due to the roughness. Still, overall, the entire 1 gallon bucket covered what was about 18 square ft of crown with a bit left over. I might have used 3 quarts or so. The chimney was 56 years old and part of the roughness was from prior partial repairs so different parts degraded differently and there was much material to be removed. Still, the repair with this product was successful and it looks great. The next guy that has to use three ladders to go up and inspect the chimney crown in about 20 years will really admire my work! ## Features - ELASTOMERIC WATERPROOF SEALANT: Creates a durable, flexible waterproof membrane that seals and protects chimney crowns from water intrusion; this chimney sealant prevents leaks, cracking, and deterioration, ensuring long-lasting protection - FLEXIBLE CHIMNEY REPAIR SEALER: Perfect for sealing small cracks and surface flaws in chimney crowns; this long-lasting, flexible sealer won’t crack or chip over time and requires no mixing or special bonding agents; not for gaps or cracks over ¼” - VERSATILE & EASY TO APPLY: Ideal for chimney crowns, corbels, parapets, and masonry sills; no primer needed, just brush on two coats of this waterproofing sealant for a strong, weatherproof barrier; can be tinted with mortar dye for a seamless look - SURFACE PREPARATION: Ensure the surface is clean and dry; use a stiff poly or wire brush to remove loose particles; protect the roof with drop cloths to prevent spills; this chimney crown sealer is solvent-free and safe for the surroundings - DRY TIME & COVERAGE: This waterproof coating sealant cures in 2-4 hours, depending on temperature and humidity; it covers about 40 square feet per gallon ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00UZLZLE4 | | Best Sellers Rank | #18,982 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #32 in Industrial Coatings | | Brand | CHIMNEYRX | | Brand Name | CHIMNEYRX | | Color | Light Gray | | Compatible Material | Masonry Materials (Brick, Concrete, Stone) | | Customer Reviews | 4.8 out of 5 stars 1,234 Reviews | | Item Dimensions | 8 x 8 x 8 inches | | Item Form | Liquid | | Item Weight | 10.2 Pounds | | Item dimensions L x W x H | 8 x 8 x 8 inches | | Manufacturer | SaverSystems | | Material | Elastomeric Resin | | Material Type | Elastomeric Resin | | Model | 300014 | | Number of Items | 1 | | Part Number | 300014 | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Chimney Crown | | UPC | 072348971113 709057920018 | | Unit Count | 128 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Material:** Elastomeric Resin - **Brand:** CHIMNEYRX - **Style:** Compact - **Item Weight:** 10.2 Pounds - **Item dimensions L x W x H:** 8 x 8 x 8 inches ## Images ![ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon - Image 1](https://m.media-amazon.com/images/I/614zeR1lb6L.jpg) ![ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon - Image 2](https://m.media-amazon.com/images/I/71Hcil17HpL.jpg) ![ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon - Image 3](https://m.media-amazon.com/images/I/61qeq0N-7mL.jpg) ![ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon - Image 4](https://m.media-amazon.com/images/I/612xLCS8p8L.jpg) ![ChimneyRx 300014 Brushable Chimney Crown Repair – Elastomeric & Waterproof Coating for Crowns & Masonry - Fast-Setting & Long-Lasting Protection Crack & Leak Prevention - 1 Gallon - Image 5](https://m.media-amazon.com/images/I/71FtxeU0hGL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb Product... *by K***O on July 31, 2019* This product worked to perfection!
