Can a second coat be applied? Will the product adhere to itself?
Asked by Odonnell87 May 12, 20211
AnswerThank you for posting your inquiry. While one application is usually sufficient for normal joint/gap filling, for deeper joints ~1/4” or more, two or more layers (with a full 24-hour drying interval between applications) can be done. Of note: The maximum fill depth should not exceed 1/2". Second applications can also be made to "touch up" missed areas, low areas or for better cosmetic appearance. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
can i fill a nail hole and put the nail back in the same place?
Asked by doodi May 8, 20216
AnswersHi Doodi, This 'caulk' is little more than paintable toothpaste for very small cracks. It is not designed to hold nails or screws that have pulled out of drywall. I'd suggest switching to a wall anchor - if needed.

Is it accurate for exterior Shed siding
Asked by Karl March 22, 20212
AnswersHi Karl, I would recommend that you consider some higher quality alternatives. This is entry-level caulk and will not hold up for 40 years, despite what the tube says. Decades of real world professional experience have shown me that you can consider 2 better alternatives: DAP Dynaflex Ultra or OSI Quad Max. You didn't state more specifically what you needed to caulk, however, please consider either of these as vastly superior alternatives to the Alex Plus. Both alternatives are sold by Home Depot.

Asked by PassDaSalt February 25, 20211
AnswerThank you for posting your inquiry. DAP Alex Plus is designed, marketed, labeled, and recommended for use as a general-purpose trim/molding sealant. It is not designed, tested, marketed, labeled, or recommended for use as a primary construction/flooring adhesive. For this type of application, we would recommend the use of DAP Weldwood Floor Tile Adhesive. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

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.

Thank you for posting your feedback. We're sorry to hear about your experience with DAP ALEX PLUS. 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. 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 and to discuss alternate product options.

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?

Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX PLUS. Based on the photographs that you have posted (depicting your application), it would appear that the product has been applied to "butt joints". As indicated on the product package label and supporting product literature: "Not for continuous underwater use, filling butt joints, surface defects, tuck-pointing or expansion joints." Product applied in these types of conditions/joint assemblies, will not perform as designed. For joints where more flexibility is required (such as butt joints), more specialized elastomeric sealants such as DAP DYNAFLEX 230 or DAP EXTREME STRETCH would be recommended. Should you have any additional questions or require further assistance, please free to contact DAP’s Technical Customer Service Department at 888-327-8477.

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.
