Masonry Water Repellent

Masonry water repellent is preventative maintenance that will protection your chimney over the years. Our Masonry water repellent comes with a 10 year manufactures warranty. (Verify it is 10 or 12 years). We have been in the industry for over 15 years and have gone back to applications done 10 years ago and tested the chimneys applied and found the water proofing was still effective.

There are two different types a water repellent. They are a film and a penetrant. We always apply a penetrant. The benefits of this method are that it is vapor permeable and will still allow the chimney to breath. It is also VOC compliant and will not damage any plants or surrounding materials. This water repellent is water based and will absorb into the masonry. When water is applied to the masonry it will bead up instead of absorb into the masonry. A film applies a thin layer over the masonry. This layer will not allow the chimney to breath and can trap moisture. It does not allow water in or out. It can also change the color or the masonry and give it a shine. We do not use films we only used penetrants.
