Absolutely. Acrymax is being used successfully over substrates that include asphalt built-up, modified bitumen, shingles, transite, aluminum, wood, concrete, masonry, slate, and other common building substrates. Roofs, decks, window sills, stucco and masonry walls are among the components of the building envelope that have been weatherproofed and protected by Acrymax coating systems. Wherever a waterproof, flexible, and durable membrane is required Acrymax is usually the most effective answer.
