    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.

    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.

    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.

    I bought ALEX PLUS® clear caulk, but it is white when I apply it.

    DAP® ALEX PLUS® is a latex-based formulation so it goes on white and dries clear in 7 days, depending on joint depth, temperature and humidity.

    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.
