GacoFlex E5320 2-Part Epoxy Primer/Filler 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.

Features & Benefits

• Excellent adhesion to most surfaces
• Improves GacoPro Roof Coating adhesion
• Helps prevents asphalt bleed-through

Coverage

When used unreduced as a block filler, the coverage is 70-100 sq. ft. per gallon (6.5 to 9.3m² / 3.78L). When reduced with one pint of water per gallon (0.5L per 3.78L) of mixed GacoFlex E5320 and applied to smooth concrete, the coverage is 200-250 sq. ft. per gallon (18.6 to 23.2m² /3.78 L).

NOTE: Actual coverage may be less due to surface profile, losses due to overspray and wind, and residual coating left in the container.

GacoFlex E5320 2-Part Epoxy Primer/Filler may be applied by brush, roller or spray;

• On single ply membrane roofs, apply one coat at the rate of 1 gallon per 500 sq. ft. (combined material will need to be thinned 10%-20% with water to achieve this spread rate).
• On metal, apply one coat at the rate of 1 gallon per 300 sq. ft.
• On asphalt-based surfaces including smooth cap sheet, apply 2 separate coats of 1 gallon per 250 sq. ft. For granulated surfaces, apply 2 separate coats of 1 gallon per 200 sq. ft.

Allow the first coat to dry for a minimum of 2 hours before application of the second coat. Allow to dry a minimum of 6 hours before application of top coat. Dry time is dependent upon temperature and humidity.
