  • Technical Data
  • Is this caulk available in other colors?

    No, it is only available in white

    Can I apply a layer of this caulk over 100% Silicone in order that I may paint?

    No, this product will not adhere over 100% Silicone.

    Can this product be used in exterior conditions?

    Yes. After cure the product can weather temperature from -30 to 180 F

    What is the maximum joint size for applying DAP® ALEX® acrylic latex caulks?

    The joint size shouldn’t exceed ½” wide by ½” deep. If the joint depth exceeds ½”, insert foam backer rod material into the joint before applying the sealant.

    Can DAP® ALEX® acrylic latex caulks be used outside?

    Yes, DAP® ALEX® acrylic latex caulks can be used in both interior and exterior applications. For exterior applications, they should be applied in temperatures above 40°F, and not when rain or freezing temperatures are forecasted before a full cure can occur. Cold weather and high humidity may slow down cure time.

    What is the recommended clean-up for DAP® ALEX® acrylic latex caulks?

    Before drying, they can be easily removed with soap and water. After the caulk has dried, it will need to be cut or scraped away.

    Where can I use DAP® ALEX® acrylic latex caulks?

    DAP® ALEX® acrylic latex caulks are ideal for filling and sealing gaps and cracks around window and door frames, molding, trim, baseboards, corner joints, and more. They have excellent adhesion to painted and unpainted wood, aluminum, vinyl, metal, brick, drywall, concrete and masonry.

    What are paint shiners?

    Shiners are unsightly glossy spots that appear when some flexible sealants are painted. DAP® ALEX PLUS®, ALEX FAST DRY® and ALEX FLEX® will not gloss or discolor paint.

    Why is ALEX FLEX® ideal for Molding and Trim?

    Sealing molding and trim can be a tricky project if the wrong sealant is used. Multi-piece crown molding can have up to five or more moving parts that must be sealed. Seasonal changes can cause wood trim to expand and contract, stressing seams year round. DAP® ALEX FLEX® provides maximum flexibility and adhesion for a crack proof seal, as well as fast paintability and no paint shiners, making it ideal for molding and trim projects.
