CUSTOMER REVIEWS

Rated 3.6 out of 5 by 23 reviewers.
Rated 1.0 out of 5.0 by This stuff is garbage We used this caulk on our woodwork before painting everything white. The coverage seemed good at first, but a year later, it's cracked in many places and we need to re-caulk. Wish we would have used a better quality product! May 28, 2012
Rated 3.0 out of 5.0 by Low cost and easy to apply, but poor flexibility Easy to apply, water cleanup. Commonly used by the DIYer. However note that the joint movement allowance specified on the DAP website for this product is only +/- 12.5% . If your application experiences temperature and humidity swings, it will most likely crack (it has happened to me on numerous window area joints). For a high flexibility use an elastomeric caulk, which advertise over +/- 25% joint movement. The consumer grade would be DAP Dynaflex 230. There are also other professional grade caulks that are better (e.g. Tower Tech 2 or Big Stretch). So in summary, this stuff is only acceptable for interior joints with a constant temperature and humidity. But for just a few more bucks per tube you can use a professional grade caulking.

Rated 3.0 out of 5.0 by Decent for interior trim - does not react well to high temperature locations I have used this product for many years and never had a problem. It paints over well and does not shrink too much when dry. I recently sealed a tongue/groove ceiling treatment using this product and after 6 months it has yellowed and cracked badly in many places. I guess the higher temperatures in the ceiling were too much. Bummer - took me 2 days and 15 tubes to complete. Will have to redo that with a better suited product. May 19, 2014
Rated 5.0 out of 5.0 by READ THE CURE TIME! The cure time is 168 hours! That means this product must not get wet for at least 168 hours if it is to adhere properly. With this in mind we can see that one must remember to keep this stuff dry for the entire cure time if it is to last for 35 years. Do not use this product in bathrooms or kitchens unless paint will be covering it. For unpainted applications you must use a silicon caulk like GE Silicon II. Latex doesn't last long if it gets wet. The only reason for using latex caulk is that paint will stick to it. Paint does not stick to Silicon. January 21, 2014
Rated 1.0 out of 5.0 by Caution when using for exterior jobs. After this product failed 3 days after I applied it I wrote DAP the following: I recently bought and applied your Dap "Acrylic Latex Caulk Plus Silicone" (7079818101) to the exterior of my exterior access door framing and threshold on a sunny day in the low 60's F; hoping a eliminate issues I have. Rain moved in over 36 hours later and afterwards I learned most of the caulk had washed out. Neither the container nor your Technical Bulletin indicated what full cure was however it was implied to be within hours of application. Prior to my re-caulking what do you really mean to be "fully cured" in real time? DAP’s response was as follows: --- On Mon, 1/21/13, from a Product Information Specialist at DAP “The full cure time for DAP ALEX PLUS - Acrylic Latex Caulk Plus Silicone is 7 - 14 days, depending on temperature and humidity levels. We recommend you do not apply the sealant if rain or freezing temperatures are forecasted to occur in the following five days.“ If these conditions are not possible in the near future, you may consider DAP® 3.0 ™ Window, Door, Trim & Siding High Performance Sealant as an alternative. This product may be exposed to moisture just 30 minutes after it is applied. Below is a link to the product's web site for further details and where to buy information: Now, then why market this product for anyplace east of the Mississippi River, given it’s an event to NOT have rain for over 14 days? I rest my case! Also note the following stating that even DAP Dynaflex 230 (costing nearly twice as much as ALEX Plus) requires the same cure time. --- On Mon, 1/22/13, from Product Information Specialist at DAP ”Dynaflex 230 also requires 7 - 14 days to reach full cure, depending on temperature and humidity levels.” January 24, 2013
Rated 5.0 out of 5.0 by does the job good stuff, used for exterior house caulking.. just make sure to have a wet rag handy May 6, 2010
Rated 5.0 out of 5.0 by Great for deco dening I use Alex Plus to deco den and it works great! I use this product a lot! July 12, 2012
Rated 5.0 out of 5.0 by Excellent sealant I used a half dozen tubes to caulk my house just before winter arrived. I used it around paintable surfaces, like door and window borders (non-paintable surfaces like brick or concrete can use a more silicone-based caulk). Please note that you need to apply it in mild weather; once it has cured it will be fine in cold weather. Combining this with other weatherstripping and insulating products has cut my electric bill in half for the entire winter, and has sealed up some really drafty leaks in the house. I would highly recommend it. February 20, 2010
