APPLICATION

PRIMER

None required for wood or urethane foam. Standard sealer system should be used on concrete surfaces other than limited flashing details. Use Gacoflex E-5320 on steel or aluminum, U-5677 on copper and E-2465 on glass and synthetic surfaces.

MIXING

Mix with a INDCO type folding mixer (use extension for 55 gallon (208 L) drums) before application to assure uniform color and consistency.

APPLICATION

Apply by brush or roller as received. Thinning up to one pint per gallon (.5 L/3.8 L) is permissible if viscosity increases. For spray application, use as received. For cold weather application, keep material stored above 65ºF (18ºC). Maximum time between coats is 72 hours. If this time interval is exceeded, prime between coats with GacoFlex U-5677 or E-2465 primers.

CLEAN UP

Clean spray equipment with T-5130 thinner. Recirculate through lines and gun until residual Ure-Cap U-68 is removed.

CURE

Applied coating will cure in 24 hours with 70ºF (21ºC) and 40% relative humidity. Lower temperatures and humidity will require longer times to cure.
