Rated 3.5 out of 5 by 10 reviewers.
Rated 1.0 out of 5.0 by Avoid at all costs Let me start by saying I have never posted a review of any product or service ever. I was so displeased with this product that I am actually taking the time post. I used this product on crown moulding in 4 rooms as well as floor boards and trim around door frames. One or two days after applying and painting, the product shrunk leaving cracks everywhere. I had to go back and re-caulk one to two more times before it finally dried with no cracks. Do not waste your time or money on this product unless you like doing things two to three times. Spend the extra money and go to Sherwin Williams. I did for the upstairs and only had to do the job once. March 10, 2015

Rated 4.0 out of 5.0 by Always use + silicone for caulking molding I have made the mistake in the past of caulking crown molding with straight latex caulk. Save yourself the touch-up work and use this from the start. December 23, 2014
Rated 5.0 out of 5.0 by I am satisfied with my purchase. My last purchase was this morning and I am satisfied with the lumber I purchased and the help I received. The caulk I purchased a couple of weeks ago worked find as well. October 21, 2014
Rated 1.0 out of 5.0 by mediocre at best Ease of application and product consistency are very good, but this product will last about two years at best before it cracks and splits. I've used this product on painted floorboards and when it cracks it's a major hassle having to re-paint two different colors after re-caulking. My best results have been with elastomeric types that can last up to 7 years or so. March 21, 2011
Rated 4.0 out of 5.0 by Excellent Product Using Caulking Every Day. This Caulk Dries Fast and looks Great. I Would Recommend this to any Professional in the Business. September 16, 2014
Rated 5.0 out of 5.0 by Alex fast dry!!! This is a great caulk product, I have used it in many application throughout my home. My house is 160+ yrs old and I'm doing lots of work. Alex plus Fast dry is great to help keep projects moving. It is easy to use, quick to dry, fast to paint, and a great fast product. I would recommend this to anyone for use in their home.

Rated 1.0 out of 5.0 by Slimy mess No way. This product was a wet, slimy mess that would not hold in vertical or overhead gaps around a window. A complete waste. I'm a fan of Alex Plus and thought the fast dry would be no different, but all I got was a huge mess. I do not recommend it to anyone in any situation. Pathetic. August 4, 2013
