GRO-MAST™ Industrial Coating is a revolutionary white, high-hiding, reflective, mildew resistant, 100% acrylic, elastomeric, protective coating for roofs and masonry surfaces. It is formulated with the highest quality raw materials available. Because of its high content of acrylic elastomeric vehicle, the retention of the elongation properties helps the product to bridge cracks and very porous substrates. It contains no plasticizers to leach out and cause the membrane to become brittle, offering superior flexibility and elongation at low temperatures. Scientific laboratory testing has established the fact that GRO-MAST™ will endure the elements of weathering for 30 years without deterioration.

The above actual photographs depict how GRO-MAST™ can lower roof surface temperatures because of its reflective qualities. Notice how the egg on the untreated metal surface on the left is fried from the heat of the sun, while the egg on the right on the surface protected by GRO-MAST™ is virtually unchanged from its original state.
