Works great
We love using this silicone to finish off our trim and get it ready for painting. It cleans up real nice and paints easy.

It comes off
I am disappointed in this caulk. I cleaned the surface hours before, put it on, let it dry up for several days, and when I’m ripping the tape off it comes off on the edges. This means the ceiling paint will rip off too when I’m taping it. I’ve never experienced this before.

Thank you for posting your feedback. The issue that you describe, regarding your use of masking tape, is not related to a product performance issue, rather it is as a result of the application technique employed. When using masking tape, the tape should be removed immediately after tooling and prior to the applied sealant skinning over (surface drying or drying through). If you wait until after the sealant has skinned over or dried through to remove the tape, you may pull up the sealant with it (as the tape typically becomes embedded under the applied sealant). At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information regarding your project and to offer some additional application guidance.

    My go to caulking to close up gaps!
    Very easy to apply and I generally use this caulking to close up gaps no more then 1/8 wide. I recently learned the secret to having clean caulking lines and it’s to go over the initial caulking bead with a wet finger and then using a wet sponge to clean up the line. This caulking is paintable after it dries.

      Poor choice
      I sealed the relief joints of a pool deck with foam backer rods and this caulk. A day later I painted the sealant with paint to match the deck. After a week the sealant shrank and rain has eroded the sealant staining adjacent areas with white residue. It is a mess.

      Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX FAST DRY. DAP ALEX FAST DRY is a general-purpose trim sealant, is not designed, tested, labeled or recommended for use on "traffic surfaces" (general flooring, sidewalks, driveways, patios or pool decks). Traffic surface applications require the use of more specialized products, such as DAP Premium Polyurethane Adhesive Sealant or DAP 3.0 High Performance Self-Leveling Concrete Sealant. For a recommendation on the proper products and methods for this type of work, please feel free to contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

        Product turned liquid
        Caulked around shelves on wall. Product is very thin and shrunk down after drying requiring second caulking. Used about 1/10 of tube. A few months later when I went to use tube it had liquified and came out like white water.

          It is the best painters caulk we ever used. It goes on smoothly, dries quick, looks good.

          Great product
          [This review was collected as part of a promotion.] I used my sample of Alex fast dry acrylic while repairing some flooring and drywall behind my dishwasher. Due to water damage, I had to cut out 6 inches of drywall (from floor up). The acrylic worked great for sealing gaps around the new piece. It spreads evenly, smoothly and did not clog. I will use this acrylic in the future.

            Great products for around the home touch ups and projects
            [This review was collected as part of a promotion.] I used the product for sealing a window that had openings letting wind and water through, and I needed to do something to seal the area. I wanted to use this product since it was indoor and outdoor use (I also had to seal a couple spots under the window on the inside and outside) and it worked well. I did not have any issues while using this and it was an easy application, dried quickly, and didn't leave a huge mess to have to clean up afterward. I had see this product before but didn't use it for anything in the past. Now I know I like it I will probably keep some around for when I have more of these projects as I'm going through doing small fixes to the place. I included a picture that has the before where you can see right through parts of the window that were open and the after, now sealed. I am happy with this product and don't have any cons since I did not come across any issues during use.

              Smooth!
              [This review was collected as part of a promotion.] I received a sample of this caulk just as I was starting an outdoor project. I installed windows and lots of exterior siding. The caulk is rated for indoor/ outdoor use. My sample tube went quickly, due to the size of the project. I was very pleased with the smoothness and ease as it came out of my caulk gun. I wound up buying 6 more tubes to finish the project. The price is very reasonable, takes paint well and cleans up easily. I am not sure how the caulk will last long term, but with the silicone component to it, I do expect it to last a good while. I would certainly recommend this product. Now, if you will excuse me, I need to go buy one more tube...
