Elastomeric Coatings: Problem Solving For Masonry Substrates
Yesterday Bill & Kevin Burnett wrote a post for the San Francisco Chronicle that addresses What to check when paint won’t stick to stucco. We figured we would add our two cents.
Elastomeric coatings were developed in the 1950s to answer the problems of paint cracking and peeling on masonry substrates; concrete, concrete block, cinderblock and stucco. Most substrate materials, particularly masonry, will contract and expand when exposed to heat, weather, moisture in the form of humidity and other climatic conditions. Elastomeric coatings are formulated to handle the expansion and contraction without cracking, often lasting for years longer than regular house paints.
