RubberRock T-200 is an environmentally safe dual component spray applied 'instant-set' protective coating specifically designed to provide heavy-duty waterproof protection for roofing restoration and new construction. When cured the product forms a seamless and fully adhered surface membrane. RubberRock T-200® strongly adheres to most roof substrates, providing waterproofing performance that is not affected by strong sunlight or airborne contaminants. It bonds extremely well with TioCOAT® to provide a bright white surface that will not delaminate.
