United Coatings™ Surface Seal SB Roof CoatingDescription United Coatings™ Surface Seal SB Roof Coating is a solventbased, sprayable thermoplastic rubber coating, which cures to form a seamless rubber membrane. It is highly reflective, provides extra protection, and is highly flexible to accomodate temperature-related expansion and contraction of the roof system. Surface Seal SB (white only) is an ENERGY STAR® qualified reflective product that will help to reduce building temperatures. Surface Seal SB (white only) is listed by the Cool Roof Rating Council for solar reflectance and thermal emittance. Available in white and custom colors. Ideal for application on most commercial roofs in temperatures as low as 32°F, providing product is stored at room temperature prior to installation. Sizes Available: 5 gallon (18.9 liter) pail 54 gallon (204 liter) drum Uses United Coatings™ Surface Seal SB Roof Coating is a liquid-applied seamless sealant membrane used in the retrofit of most commercial roof surfaces. United Coatings™ Surface Seal SB Roof Coating is designed to protect and restore aged modified bitumen, BUR, metal, wood, concrete, and EPDM roof surfaces, and to increase a roof’s reflectivity. Advantages - ENERGY STAR® qualified reflectivity can dramatically decrease building temperatures (white only)
- Highly reflective and listed by the Cool Roof Rating Council for solar reflectance and thermal emittance (white only)
- Ideal for modified bitumen, BUR, metal, wood, concrete, and EPDM
- Designed to be applied at temperatures as low as 32°F
- Strong; forms a flexible seal that will not become brittle
- Flexible; will expand and contract with roof
- Enhances the adhesion of GAF Liberty™ and Freedom™ Self-Adhering Membranes. Great for use in high wall flashings.
