Trade Professional Information
- Required Tools: Sealant gun, masking tape, utility knife, cleaning supplies (water), Everflex Supaprime primer (optional)
- Trade-Specific Tips: Ensure surfaces are clean, dry, and free from contaminants. Priming is not typically required, but for optimal adhesion on certain substrates, use Everflex Supaprime primer. Mask joint edges for a neater finish. Avoid overfilling the joint and tool the sealant before it skins. Clean up with water while the sealant is still wet.
