TOPCOAT® Flashing Grade
Spray Formula
Description
TOPCOAT® Flashing Grade Spray Formula is a light gray, water-based
100% acrylic elastomeric sealant which is applied to seams, fasteners, flashings,
and penetrations prior to the application of the TOPCOAT® Elastomeric
Roofing Membrane. It is identical to regular TOPCOAT® Flashing Grade
Formula with the exception of viscosity. It is designed to be easily applied with
an airless sprayer. Like the TOPCOAT® Elastomeric Roofing Membrane,
it has superior adhesion, flexibility, and resistance to ultraviolet degradation.
Uses
Flashing Grade Spray Formula is designed for use on metal, wood, and concrete. Provides
a seal along seams and around fasteners on metal roofs and excellent sealing around
curbs and counter flashings. Do not apply at temperatures below 42°F. Substrate
temperatures must be below 120°F when applying product.
