Elastomeric Roofing - TOPCOAT Surface Seal SB

TOPCOAT® Surface Seal SB Membrane



Description

TOPCOAT® Surface Seal SB is a solvent-based, sprayable thermoplastic rubber sealant, which cures to form a seamless rubber membrane. It is highly reflective, provides extra protection, and is highly flexible to accommodate temperature-related expansion and contraction of the roof system. TOPCOAT® Surface Seal SB is an ENERGY STAR® qualified reflective product that will help to reduce building temperatures. TOPCOAT® Surface Seal SB is listed by the Cool Roof Rating CouncilSM 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.


Uses

TOPCOAT® Surface Seal SB Membrane is a liquid-applied seamless rubber membrane used in the retrofit of most commercial roof surfaces. TOPCOAT® Surface Seal SB Membrane is designed to protect and restore BUR, Modified Bitumen, EPDM, Metal, Concrete and Wood roof surfaces and to increase a roof’s reflectivity. Substrate shall not pond water for a period longer than 48 hours. Surface must be free of ponding water, ice, snow, and debris prior to application. Do not apply at temperatures below 32°F. Substrate temperatures must be below 120°F when applying product.
