SikaCoat-333 elastic acrylic roof coating

A water-based acrylic liquid membrane that primes itself and reflects sunlight, helping reduce heat build-up. Use it on flat and sloping exposed roofs, external walls and roofs with many details such as drains, roof lights and penetrations. It bonds to concrete, mortar, roof tiles and metal (steel, zinc, aluminium), bridges micro cracks, and goes on by roller, brush or airless spray.
