There are approximately 40 million masonry chimneys in North America and the most common problems with these structures is water penetration. Water causes over 1 billion dollars in damage annually in the form of staining, loss of insulation value, freeze-thaw damage, deterioration, and ultimately structural failure. All new and existing masonry chimneys are susceptible to water damage and, even if repaired, chimneys will continue to deteriorate if they are not protected. It is important to address this problem before serious damage occurs. Water damage can be prevented by applying a 100% vapor permeable water repellant that keeps moisture out of the chimney system by filling all gaps up to a 1/4″ but allows water vapor to escape which helps condensation from continuing to cause damage. This is the best solution for a variety of exterior masonry applications including, patios, walkways, pool decks, and wall systems.
