Acrylic Coating

White, water based acrylic roof coatings provides the highest reflectivity and the best longevity at the most economical price.

Water-based acrylic roof coatings have little odor. A roof coating can be applied without disrupting the occupants in the building. This makes acrylic coatings ideal for buildings that function as schools, residences, food preparation areas, hospitals and offices.

Energy Efficient Roof Coatings

Energy-efficient roof systems are in demand. Rising energy costs and the effects of urban heat islands have made white, reflective roof systems the product of choice for most roof maintenance applications. Using energy-efficient roofing materials results in cooler roof surfaces and less energy spent for air conditioning.

Because of media attention about ENERGY STAR ratings and reflectivity, roof coatings frequently are specified as finish coats for built-up and modified bitumen roof systems and maintenance coatings for existing roof systems, including built-up, modified bitumen, metal roofing, spray polyurethane foam, concrete and single ply.

Cool to be White

Application of water-based acrylic coatings do not require extraordinary personal protective equipment. The equipment usually required is no more than a pressure washer, paddle mixer and airless sprayer. This makes it easy for roofing contractors to enter into the coatings application market.

Various Options for Acrylic Roof Coatings

• Acrylic Coating over Smooth Built Up Roofing
  • An asphalt emulsion must be applied to stabilize the surface. Asphalt emulsions add additional surface waterproofing capabilities.
• Acrylic Coating over Granulated Modified Bitumen
  • A bonding primer can minimize blisters and pinholes in the topcoat.
• Acrylic Coating over Metal Roofing
  • Galvanized metal is an excellent substrate for acrylic coatings. Solvent based alkyd coatings can adversely react with zinc and lead to flaking of the alkyd paint from the roof. Do not use acrylic coatings over a Kynar® coated sheet. Rust primers are available that seal rusted metal surfaces to ensure moisture and oxygen cannot penetrate and cause the metal to continue to rust.

What is an Acrylic Coating?

An acrylic coating is liquid coating system based on an acrylic resin. Generally, a latex-based coating system that cures by air drying. Acrylic coatings are formulated with pigments, acrylic polymers and water. Pigments, such as titanium dioxide, produce the white color, which provides the desired ENERGY STAR-compliant reflectivity.
