Questions & Answers

Can it fill wall cracks
ByMay 31, 2025
1 Answer | 
Answer This Question

Thank you for posting your feedback on DAP Alex Plus Acrylic Latex Caulk Plus Silicone. As is the case with all of DAP's sealants, they are designed for "bead" application. The application that you describe (crack filling) would appear to be a "surface defect" repair, which would typically be made with a repair filler. As indicated on the product package label and supporting product literature: "Not for filling surface defects." At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477, so that we can obtain some additional information from you about your project and to discuss more appropriate repair product options.

          Does this product adhere to tiled wall edges that have been previously water sealed using sealers such as 511 impregnator?
          ByMar 25, 2025
          1 Answer | 
          Answer This Question

          Thank you for posting your inquiry on DAP ALEX PLUS. As a general rule, sealers should be treated as bond-breakers (surfaces/materials that other sealant/adhesives are not expected to properly bond to). Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

                  Horrible Product
                  Terrible product. I used it to caulk the inside joints of my shower and let’s sit for two weeks. The cock turned to butter after two showers. I tried this twice and got the same result. This stuff stinks. It isn’t worth the money and I would never recommend it!!!!!

                  Thank you for posting your feedback on DAP Alex Plus Acrylic Latex Caulk Plus Silicone. DAP Alex Plus is designed, tested, labeled, and marketed for use as a trim and molding sealant. It is not designed, tested, labeled, marketed, or recommended for use as a kitchen and bath sealant.

                    Labeled wrong
                    I bought 6 of these to do some repairs around my home and they all were marked the wrong color! I needed clear and they were white! Imagine the mess I had to clean up when I started caulking, thinking that it was gonna dry clear because I’m a 65 year-old woman the first time I’ve ever did this, but I know about Claire and it was!white! They went a pretty good chunk of my retirement money that month very disappointed! I don’t think I’ll ever buy your product again!

                        Great for helping get our campus spruced up!
                        I got to try DAP for free and I was so excited for the opportunity! Working on a campus with dark “statement” walls means that the students accidentally end up damaging walls as a normal part of wear and tear. I broke my wrist and damaged two fingers right before I could start the project! Fortunately, I had a great office mate take over for me. This wonderful guy went around and filled in the “nooks and crannies” as he called it, before painting the spots back. It worked so well!

                          Great product for the price point. Easy to apply and clean up. Takes paint well and does not shrink. Apply correctly and make sure to fill the voids completely.

                            Will not recommend this caulk
                            I used this product to seal a very small gap around my newly installed air conditioner from inside my house and within 3 days it cracked Allaround the unit on 2 air conditioners. Now I have to remove this and apply a better quality caulk dap caulk used to be better in the past but your company most likely cut corners to save money, making this product inferior for a simple sealing task I will not buy dap products anymore as There are Better quality products out there

                              Just got done installing and caulking baseboards in bedroom. This caulk was easy to apply and smoothed out well with a wet finger. Blended well with the painted off white baseboards. Dried quickly and looks great. On to the next room.
