Helpful Tips

  • 1

    Proper surface preparation is key. Remove any old caulk from the seam or joint by cutting or scraping it away. Then clean the area with soap and water to remove dirt, dust, grease or debris. Rinse thoroughly. Make sure the area to be sealed is clean and dry to ensure good adhesion.

    Want straight lines? Apply painter’s masking tape to either side of the joint before applying the sealant. Remove the tape before the sealant skins over – about 2-5 minutes. To remove, lift the edge up at a 45° angle and pull away from you.

    To get a professional-looking finish after the sealant has been applied, smooth the bead of sealant with a caulk finishing tool dipped in water. Do this before the sealant starts to skin over, about 2-5 minutes.

Frequently Asked Questions

A. DAP® ALEX PLUS® 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.

A. 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.

A. 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.

A. 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.

A. 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.

A. 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.

A. 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.
