Review: Easy application, solid product. - Easy application. Cures quickly and makes a solid continuous seal along the cap. First coat paints on like paint to ensure all cracks and crevices are filled. Short time later it tacks up to allow for a heavier finish coat. I actually put 3 coats on my chimney cap and still had product left over. If it holds up well this would be a very recommended product.
Review: Superb Product... - This product worked to perfection! 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.

### ⭐⭐⭐⭐⭐ Seems to be a good product
*by T***R on 21 October 2018*

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!
