GacoFlex E5320 is a two-component, water-based epoxy primer that is ideal for use on most roofing surfaces including metal roofs and flashings. This easy-to-apply primer bonds to properly prepared roofing surfaces and improves adhesion of GacoFlex silicone coatings and other top coats, especially on weathered surfaces that are difficult to get completely clean.
On asphalt-based surfaces it may help prevent bleed-through, and when top coated will help prevent corrosion. When mixed with ordinary sand, it’s a masonry block filler.
