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.

      Horrible stuff
      Do not buy this product. I put it around my sink and even though it did dry clear, when it gets wet it is white again. When it goes white, it softness and separates. This has been in my sink for a few months now but I just couldn't take haw disgusting it gets and pulled it out. Note: The dry time states 7-14 days cure time. How can a product for things such as a window require 14 days dry time. Rain, dampness, humidity, need I say more. I had to give it 1 star but deserves none.

          If you're using this in a dry environment it works great. If however, you're using it where it's going to be damp after you applied it, don]t use this product. I used it to seal the rotted basement door jamb I had removed and installed a composite lower jamb kit and the brick moulding on a basement door that is beneath my deck. It rained about 6 hours after I completed the job. I had the deck above the door covered with a tarp to keep the rain at bay. This product literally ran out of the joints where the jamb kit meets the good part of the jamb and where the jamb kit meets the aluminum threshold. The seal on the brick moulding was fine until you got down the the lower last foot. Again this product was like clam chowder running out of where I had applied it. I did re-apply it and the weather cooperated and it seems fine and it's all painted. It does say paint-able in 30 minutes so I assumed it would work. In Nevada it would have worked fine.

          Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX PLUS. As indicated on the product package label and supporting product literature: "Do not apply if rain or freezing temperatures are forecasted before full cure can occur. Cold weather and high humidity will slow down cure time." Additionally, DAP Alex Plus is designed, tested, and recommended for general purpose sealing applications, such as trim and molding. The application as described will likely present moisture challenges that would require the use of a more specialized product, such as DAP Premium Polyurethane Construction Adhesive Sealant. 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 regarding your experience and to arrange to provide you with a more appropriate product for this project.

          What a disaster
          I decided to take on the project of replacing my basement exterior door's rotted lower jambs using a replacement composite frame saver kit. I used this product to seal the replacement lower jambs to the existing jambs and the aluminum threshold. Paintable in 30 minutes? I could not finish the exterior part of the job because it was to dark and would get back to it in the morning. Well it rained about 6 hours later and the clear caulk not only is still white but it's very soft and running out of the areas I applied it to, and I smoothed out and the ares I applied it to. Now I'm no expert but it does say for interior / exterior use. If it's paintable in 30 minutes doesn't that infer it's dry or dry enough to paint? Maybe I used the wrong product or this product was defective. I just won't use this product again. Now I have a mess on my hands. The jamb replacements are done, the interior trim back on, and I won't be taking it all back apart to re caulk the job. When the rain stops and I get the new brick moulding mounted, I won't use the remainder of this product to seal it. I will find a better product that does what it says it does. They say cardboard makes a great enclosure until it gets wet.

          Thank you for posting your feedback. We are sorry to see your low star review on DAP Alex Plus Acrylic Latex Caulk Plus Silicone. As is the case with all acrylic-latex (water-based) formulas, they dry solely by the evaporation of water. Accordingly, environmental conditions and application amounts will dictate dry times. Thick (deep) applications, applications subject to lower temperatures/higher humidity, damp/wet application surfaces and/or application areas with poor air circulation will dry at significantly slower rates. Thin applications, applications subject to higher temperatures/lower humidity, dry/absorbent application surfaces and/or application areas with high air circulation will dry at significantly faster rates. When more challenging applications are present or faster through cure times are required, DAP would recommend that you consider our line of fast cure sealants, such as DAP AMP Window, Door, Trim & Siding High Performance Sealant. DAP AMP Window, Door, Trim & Siding High Performance Sealant will be surface dry and ready for paint in approximately 30 minutes and through cured in 24 hours, even in cooler and/or more humid application conditions. Of note, DAP AMP Window, Door, Trim & Siding High Performance Sealant and similar fast cure sealants require solvent (mineral spirits/paint thinner) for clean-up. Should you have any additional questions or require assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
            Smooth and easy
            Got it as part of promotion, It had perfect smooth finish. I tried without any attachments too, found it so smooth even and easy to use. Instructions were clear too.. waiting for it to dry to see if it cracks or not?

              Thank you for posting your feedback on DAP Alex Plus Acrylic Latex Caulk Plus Silicone. We are sorry to see your low star review on our product. DAP Alex Plus is a water based (acrylic latex) formula, the sole drying mechanism is the evaporation of water. Dry time can be significantly impacted by cool or humid application conditions, application to damp surfaces, applications where air contact is limited or by thick (deep) applications of the sealant. Please note that full clarity is only achieved once all of the water contained within the product has evaporated. Of note, DAP For roofing applications, DAP offers a line of specialty use sealants.

              Done with this junk...
              I don't know why I have used this product for so long. It really never works well and will always crack on you within a year. The first picture is where wainscoting meets the wall and it cracked within a few months. There is no movement between the two elements. The second picture is where some new crown molding meets the ceiling. I applied this and waited 6-hours and it crazed badly. 30-minutes ready? Now I have to deal with this mess. You never get your time back. Pay for a better product.

              Thank you for posting your feedback. We're sorry to hear about your experience with DAP ALEX PLUS. Based on your commentary, it would appear that the applications that you are using the DAP ALEX PLUS sealant on may require higher performance products such as DAP DYNAFLEX 230, which is an elastomeric joint sealant with 3 times the amount of flexibility offered by DAP ALEX PLUS. 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 experience. DAP
                Became powder
                I used this product in my walk-in shower this time. After leaving it dry for few days and then took hot showers few times, it became soft like Putty and then like powder and came off! I thought, perhaps it was not specially designed for showers and bathroom room, so I bought the Kwik Seal Plus 10.1 oz. White Premium Kitchen and Bath Siliconized Caulk that is more expensive! However, it turned out to be the same (see picture). Can anyone suggest what I should use now?

                  Cracks, utter garbage
                  Cracked everywhere I used it on a bathroom and kitchen remodel. Used to be great, now I will never use it again. Had to redo all of the caulking two months later.

                    Ultimate piece of garbage
                    A month in and it has cracked every single caulking line. Every! Single! One! Every single corner corner, too. Every single flat joint, too. What a piece of garbage. "Excellent flexibility". Really??!?! 40 years? How about 40 days? I don't want my money back, I want the hours I spent applying it back!

                      Love DAP for all kinds of applications. I have used many cases inside & out on my old farmhouse I've been refurbishing. It fills in nicely & smooths well, holds paint well, & it just is a very good product that I like a lot. And I like getting it delivered to my door too! I've used it around windows, woodwork, bathtub, filling in all the spaces in the outside asbestos shingle my house is covered with, fixed a few leaks, around counter top, you name it. It stays put. I think it might be holding my whole house together! LOL!

Because you did not provide any details regarding your experience, it is difficult to provide you with a proper reply or any product usage guidance. As is the case with all acrylic-latex (water based) sealants, volume loss will occur as the product dries, this is a normal characteristic for this type of formula. Only non-water/solvent-based sealants are capable of "low/no volume loss" performance; however, these types of sealants will require the use of solvent (mineral spirits/paint thinner) for clean-up, likewise, some of these sealants are not paintable.

                        Tired of this horrible product!
                        You CANNOT get a clean bead when the tip is cut any smaller than 3/16 of an inch. I’ve installed windows and painted for decades, and have caulked thousands of windows, doors, and walls. If you’re a pro and used to high quality sealants, this product will drive you up a wall. Additionally, caulk continues to seep out despite the fact that there’s no pressure being appkied by the gun. Useless!!!

                            My favorite caulking for all jobs!!
                            I use this caulking for so many different applications. Any gaps less then 1/8” are good to be filled with this caulking. I typically wait a few hours before I actually paint over it. Use a wet sponge for the cleanest application. Run a small bead of caulking and then go over it with a wet sponge and you get a very clean and even caulking line.

                              Whole room cracked within days. Ruined paint job.
                              I will start this off by saying that I am a contractor that specializes in high end cabinetry and finishes. I have used this product before without issue but will absolutely never use it again. I spent the better part of a week prepping and painting a room in my own house to be used as a nursery only to have every single caulked joint in the room crack wide open in less than a week. Paint and primer were standard latex off the shelf at Home Depot. Primer went on before caulk. The only thing I can think of is that this was a bad batch from the factory. I don’t even care about the $40 box of caulk. It’s the repair time I’ll never get back. Very frustrating.

Because you did not provide any background or details about your use of the product, it is difficult to provide a proper explanation for the issue that you have described in this format. Based on your commentary regarding "cracking" in such a short period of time, it would appear that the application (joints/materials) that you are using the DAP ALEX PLUS on, may be experiencing a significant amount of movement/instability. Joints/materials that are prone to experience significant expansion/contraction forces may require higher performance products, such as DAP DYNAFLEX 230 or DAP EXTREME STRETCH. These types of more specialized elastomeric joint sealants offer several times the amount of flexibility offered by DAP ALEX PLUS.

                                Bad caulk, didn't last a year!
                                We prepped our house, pressure washed it and let it dry. We re-caulked every crack, joint and seam with this caulking. After a year, it has come apart and has failed. We have included 3 pictures of the many seams we have to redo. We are now having to remove this caulking and re-caulk again, after painting the whole house and garage. Very disappointed in Dap in not making a good product. The caulking we bought says it has a 35 year durability guarantee. It didn't even last a year. Now, scrape this junk off, re-prime and try to blend the paint where it doesn't look too bad. Does anyone know a good company that makes good caulking?

                                  This is a good cheap caulk, I use it primarily for filling gaps between trim and walls before painting.
                                  I have also used it for window applications to which it performs well. The caulk does shrink a little but is paintable in 30 minutes. I usually wait an hour or so. I can cap it and it still works great a few months later. Clean-up is easy compared to full silicone caulk. Caulk dries an off-white color with a matte finish.

                                    I've been using this product for at least 25 years. On our most recent jobs, we kept having consistent problems with the paint cracking/withdrawing (I would not really call it a crack, because the paint withdraws as it drys, forming what appears to be a crack, more like what you might expect when trying to paint over a pure silicone caulk). This has happens occasionally with siliconized caulks, but I've never seen anything like this - about 50% of all joints are affected. We've bought this caulk from both here and places other than Home Depot, so it appears to be a problem with the caulk's formulation itself. From what I've read on professional forums, DAP's quality control has diminished in the past decade, and many professionals won't use DAP products, period, and I will never use DAP products again, and I'd advise others not to too. We contacted DAP, and all they could say was return them to the seller. Also, they told us one batch number we bought from HD on July 4th expired at the end of that month, so we where apparently using it past it's "shelf life" in September, but the tubes had no date on them, so how where we to know HD was selling us an about to expire product! By the way, this happened with both flat paints and semigloss, and the cracking stopped when we switched to a different brand. Yes, the caulk was completely dry.

                                        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. Using a damp lent free cloth to clean up will leave a professional finish.
