Tremco Primer #1 (Not for use in the United States)
Usage: Porous surfaces, urethane sealants (Dymonic, Dymonic FC, Dymeric 240, Dymeric 240FC).
Quick-drying, one-part, moisture-curing primer used as an adhesion promoter for urethane sealants on porous surfaces such as concrete and wood.
Apply generously with a clean brush or cloth.
At 70 oF (21 ̊C), allow 30 to 45 min for primer to become
tacky before applying sealant. Do not allow primer to dry completely. The tackiness window is approximately 2 to 4 hr depending on temperatures and wind speeds.
Primed areas should be sealed the same day the primer was applied.
Coverage Rate: 100 to 600 ft2/gal
