Product Documents
Overview
CrownSeal by Saver Systems is a trowel-on elastomeric coating that forms a flexible waterproof membrane over a chimney crown. It's thicker than CrownCoat, so it suits a rougher crown, and it dries to a natural concrete or mortar look. It needs no mixing and no bonding agent. Buy from StoveSource and pay no sales tax in any state.

What to use with it
- CrownPrep crown conditioner: brush it on first if the crown is soft, sandy mortar, so the coating bonds and lasts longer.
- ChimneySaver water repellent: keeps water out of the brick below the crown.
Working below 45°F? Use Cold Weather CrownCoat. How CrownSeal compares with CrownCoat and CrownSaver is in our chimney crown repair guide.
