Bought two cases......
5 years ago
Bought two cases to do my exterior trim around windows and doors. Applied in 78 degree farenheit weather with 20% humidity between vinyl windows and pre primed spruce trim, let dry for 22 days before painting and every single joint cracked. The gaps were 1/8" wide or less. I'm thoroughly disappointed in this caulking. Not to mention there where air bubbles in the middle of every tube.

Thank you for posting your feedback. We're sorry to hear about your experience with DAP ALEX PLUS. Based on your commentary, there may be a few potential concerns that we would like to address with you. For application where significant joint movement is expected, we would recommend the use of elastomeric joint sealants such as DAP DYNAFLEX 230 or DAP DYNAFLEX ULTRA. 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 so that we can provide you with a sample of either product referenced above.

Cracks
5 years ago
This stuff would be great if it was reliable (imo). It is very easy to clean/maintain, and the silicone is an added bonus for waterproofing and flexibility. I am still dumbfounded, after using multiple tubes indoors to seal my windows, trim, and doors, to find 2 weeks later that 90% of it cracked. Wasted money and several hours of application... will NEVER buy a dap product agaib

I love this product! Typically silicone can be hard to work with, but this combination of materials that make up this sealant are outstanding. I used this around my exterior windows and doors (just moved into a new house) and wanted to not only weatherize them but also keep the bugs out. This product worked great, not only in its coverage, but also its application and cleanup (for the times I over applied). Greatest part about the product... the lifetime on it! Silicone based material will last!

Spent a long time carefully taping the seams to be caulked around my bookcase interior trim. The Alex Plus is easy to install, and paint. Looks good for about 6 weeks, then it shrinks and cracks. Did it twice thinking it would somehow be better the second time.
What a waste of time !!

DAP Technical Customer Service
Thank you for posting your feedback. We're sorry to hear about your experience with DAP ALEX PLUS. DAP ALEX PLUS is considered fully dried within a few days of application (depending on the joint size, temperature and humidity). After the product has gone through this drying phase, additional shrinkage/volume loss does not continue. The "shrinkage" that you are referring to (6 week after application) is not an artifact of the sealant's performance, it is the result of the shrinkage/drying of the surrounding wood material. Excessive joint movement can ultimately lead to cracking (interior or exterior). 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 suggest an alternate (more flexible) product.

DAP wood patch is the BEST!
4 years ago
I've used DAP plastic wood many times, always with excellent results, I decided I should probably write a review. Recently I was renovating my travel trailer camper and the interior walls had extensive water damage around the back & side windows. I used DAP to fill and smooth the large holes & cracks. It took a couple days, several layers and a bit of sanding in between but the end result was absolutely phenomenal! When dry, this product is harder & more durable than the actual wood itself. I highly recommend this product.

Excitement to frustration.
8 years ago
I was excited to get this product for sealing around my exterior home; window, trim, etc. Excellent flexibility (I need that for cedar siding!), adheres to wide range of surfaces, shrinks less (in my opinion it shouldn't shrink at all), waterproof (oh, a must --- I live in the Pacific NW!), etc. What could be wrong about this product? Oh, joy! Grinch time --- there it is in small print in 2 different sections; "Caulk ...dries clear in 7 - 14 days" and "Allow to dry clear before painting" (Seriously? 14 days?). So, when it is cured, it is clear. In 14 days. Really?!?! But the real kicker is "Don't apply when rain/freezing temps, are forecasted before full cure can occur." And, based on their label, that is 7 to 14 days. So, if there is a chance of rain within 2 weeks and you want to caulk, seal, and paint your home --- don't buy this product. Wishing now I would have purchased the "....paint within 30 minutes. Can apply in rain..." alternative brand. :(
No, I do not recommend this product.

Thank you for posting your feedback. We're sorry to hear about your experience with ALEX PLUS. The 7-14-day dry time indication on the package label is intended to be conservative. As this 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 or by thick (deep) applications of the sealant. The purpose of the guidance is to ensure the best chances for a successful application. Under most normal conditions (warm and dry), dry times are much shorter. DAP also offers a line of fast cure sealants for use under more difficult application conditions. 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 and so that we can arrange to provide you with a sample of DAP 3.0 Window, Door, Trim & Siding High Performance Sealant.

Someone's a genius, instead of using a tube of painters caulk and then switching to a tube of silicone, you just use this for both! At a fraction of the cost!! 2 years ago I caulked a tub surround with this on accident, grabbed the wrong bottle. As it was my own house I just left it. To this day , no leaks no mold, no mildew. Being a contractor, and using caulk almost daily, I can tell you this has made my life a lot easier, easy to work with, easy to clean up, and easy to pay for. Someone's a genius

Thank you for posting your feedback about DAP ALEX PLUS. Because you did not provide sufficient background information on your project, such as the application surfaces or width/depth of the applied bead, it is difficult to provide a proper response. Because this sealant is an acrylic latex (water based) formula, its sole drying mechanism is the loss of water (evaporation). The most common causes for slow drying is generally related to one or a combination of factors such as: damp application surfaces, low temperature, high humidity, poor air circulation, premature water exposure (< 24 hours) and/or deep/thick application.

Great product WHEN USED AS DIRECTED AND UNDER IDEAL CONDITIONS. I’ve never had an issue with caulking or silicone, especially from Dap. Every time I see an issue arise, it’s because of the user’s paint/primer, painting too soon on wet caulk, buying the wrong type of caulk for the job, or downright being a jack leg and blaming the product for their mistake. I will continue to buy Dap products only when it comes to caulking or silicone.

DAP Technical Customer Service
Thank you for posting your feedback on DAP ALEX PLUS. The 24 Water Ready Time indicated on the package label is intended to be a "guide" for planning purposes, however, as this is an acrylic-latex (water-based) formula, the sole drying mechanism is the evaporation of water. Dry time can be significantly impacted by cool or humid application conditions, moisture in/on the application surface or by thick (deep) applications of the sealant. As indicated on the project package label and supporting product literature: “Apply in temperatures above 40ºF. Do not apply when rain or freezing temperatures are forecasted within 24 hours. Cooler temperatures and higher humidity will slow down dry time.” Application outside of these conditions will lead to long dry times and slow performance development. Because you did not provide any details regarding your application, such as application surfaces, surface preparation, bead size, humidity, or any information regarding your application technique, it is difficult to provide you with a more detailed reply or any specific product usage guidance in this format. Should you wish to provide this information, so we can better address your concerns, or to recommend a product that is better suited for your project/conditions, please feel free to contact DAP’s Technical Customer Service Department at 888-327-8477.

Alex Plus is my first choice
8 years ago
Alex Plus has been my first choice all-purpose caulk for decades, first in New Jersey where rain and humidity where the primary exterior challenges, and now in north-central Nebraska where temperature extremes and intense sun are the challenges. I consistently get excellent results. My first and most often repeated lesson as an apprentice was, "Understand your medium." Wood moves. Some species more than others. Some environmental conditions cause more movement than others. That's the basic understanding the wood medium part. Caulks dry differently, adhere differently, and harden or remain flexible differently. As long as one understands and selects the right medium for the job, and matches media that are complementary, there will be success. But when one attempts to bind up a board and batten wall with caulk, for instance, product failure and dissatisfaction are bound to follow. The board and batten system was designed to accommodate the movement of the wide boards, so let them move, or find a caulk that cures with the elasticity of a glob of chewing gum on hot pavement.
