Gaco Flex E5320 2 Part Epoxy Primer Filler Kit 2 Gallon

GacoFlex E5320 is a two-component, water-based epoxy primer that is ideal for use on most roofing surfaces including metal roofs and flashings. Both part A and part B come in 1-gallon increments and together equal 2 gallons. 

This easy-to-apply primer bonds to properly prepared roofing surfaces and improves the adhesion of Gaco Flex 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.
