    Frequently Asked Questions

    Why is caulking important before painting?

    +

    Caulking seals gaps where water and air can enter the building envelope. Without it, moisture can get behind the paint causing premature failure, rot, and higher maintenance costs over time.

    What type of caulk do you use?

    +

    We use premium elastomeric sealants for flexible joints and polyurethane sealants for high-movement areas. All sealants are paint-grade and compatible with the finish coat for a clean appearance.
