Intercoat Adhesion of waterborne traffic paints can be a problem if the application parameters and dry time recommendations are not followed.• For Fast Dry Waterborne paints, the minimum

application temperature is 50°F and rising.

• For both paints, the temperature must be at least 5°F above the dew point and be maintained during the dry through.

• For Low Temperature Application Waterborne paints, the minimum application temperature is 35°F and rising.

• First coat must be completely cured (24 hours) before application of a second coat or new layer.
