Note: Where maximum solvent resistance is needed, apply two coats a minimum of two hours
apart. Let cure for two days with a daily maximum temperature of 70°F (21°C) or higher. For 60°F
(16°C) days, allow one week. Full cure and dry time can be longer when there is poor air
ventilation such as in tanks or enclosed reservoirs.
Application: Product may be applied by brush, roller or spray. On smooth surfaces, use a 1/4” to 3/8” nap
roller or nylon brush. When applying E5320 as block filler for porous concrete, use a 1” to 1-1/4”
nap roller. If blow holes form as the primer dries, make a second pass with a relatively dry roller;
allow 5 to 10 minutes between passes. Contact Gaco Western for application utilizing
equipment. Do not apply to surfaces which are below 50°F (10°C).
- 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.
NOTE: Application rate is job-specific. Additional material may be required.
