TOPCOAT® Surface Seal SB
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. Surface Seal SB is an ENERGY STAR®
qualified reflective product that will help to reduce building temperatures. 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
Surface Seal SB is a liquid-applied seamless rubber membrane used in the retrofit
of most commercial roof surfaces. Surface Seal SB is designed to protect and restore
aged modified bitumen, BUR, TPO, metal, wood, concrete, and EPDM 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.
