Silicones provide excellent coverage for micro cracks in exterior plasters and coatings, thereby extending the longevity of paints. This protects the structure from rain, humidity, fungus and moss. 

Our formulations have been found to be particularly effective for clay tiles, asbestos replacement cement sheets and pre-fabricated cement blocks/slabs. ELKAY can offer products that are solvent-dilutable, as well as water-dilutable.
