GacoFlex A4207 BleedTrap

Sealer for Asphalt Roofing

GacoFlex BleedTrap is a single-component, easy-to-apply water-based sealer for use on asphalt roofing substrates containing bitumen, including built-up roofing (BUR), all types of ModBit, and smooth or granulated asphaltic roofing membranes. It was developed to encapsulate the oil that commonly exudes from asphalt substrates and effectively traps it within the sealer to inhibit bleed-through to GacoFlex Silicone Coatings.



INHIBITS BLEED-THROUGH. BleedTrap Sealer traps the oily liquids that exude through a conventional silicone coating and prevents dark stains caused by asphalt bleed-through.

WORKABILITY. BleedTrap Sealer was designed to be part of a full system of integrated GacoFlex products and to be used in conjunction with GacoFlex Silicone Coatings.

EXCEPTIONAL FILM BUILD. The exceptional film build of BleedTrap Sealer provides a smoother surface for easy top coat application of GacoFlex Silicone Coatings.

CLEANS UP WITH WATER. BleedTrap Sealer is an single-component, water-based sealer that cleans up easily with soap and water.
