Product Overview

Daptex Plus is designed to meet the tough standards demanded for professional window and door installations while effectively filling and sealing large cracks, gaps and voids. Unlike polyurethane foams, it will not over expand, is toolable, moldable and cleans up easily with water. It remains soft and flexible when dry so it will not bow, buckle or distort frames. The innovative latex polymer foam technology provides water resistance and is paintable with latex paints once cured. Daptex Plus helps reduce energy loss as well as pest infiltration and is ideal for sealing air leaks to improve energy efficiency and reduce heating and cooling costs.

Customer Reviews

Rated 3.1 out of 5 by 97 reviewers.
Rated 4.0 out of 5.0 by Better than expanding foams Great find! Saw this product several times in stores and figured it was just another expanding foam. These foams do a good job when used properly and in the right application, but they are pain to use. The other day I was searching the web for an interior window sealant for a gap between a hurricane window and concrete wall. (No, nothing structural. Installation contractor did a good job of installation except for the interior of a bathroom window over the bathtub. He used a lot of caulk to cover his sins; the caulk was beginning to mold and mildew despite routine cleaning.) Backer rod wasn't right, there wasn't enough working space for grout or mortar, and the gap was too deep for caulk. My search lead me to a website where a contractor was using the DAP foam. The contractor in the YouTube video was successfully showing my application. Next day I purchased a can and today used it. SUCCESS, except now I am waiting for it to cure so I can add a small bead a caulk over it. Guess I'll do some other things like cleanup. September 28, 2016
Rated 5.0 out of 5.0 by This is great! This is a great gap filler for Windows, Doors and Walls. It's far better than Great Stuff and others because it stays more flexible than the competitors, which are rigid and hard to handle. It is very controllable as well which is very beneficial in cavity fills where the insulation must tightly fit. September 23, 2016
Rated 4.0 out of 5.0 by Does what I expected it to do We keep about 3,000 to 6,000 cans of this on hand and use it on 30 to 50 jobs a day. Primarily we use this product to seal between wood framing and wood door jambs at install. It does a good job gaps up to 1" and does not expand a great deal. Clean up is much easier than with expanded poly products. August 18, 2016
Rated 1.0 out of 5.0 by terrible results Purchased this product at more than twice the price of similar products. Used to seal up small wire and plumbing openings in my camper. After 5 days it never set up or cured. Has no strength and would be impossible to paint. Don't understand how DAP (usually good products) could market such a poor product. Now I have to try and clean it all out and do over with something else. August 4, 2016
Rated 1.0 out of 5.0 by Very Weak It installed the way the instructions indicated. It looked pretty good after it set; it filled a 3/8" gap nicely. Unfortunately, it has little mechanical strength. Painted it after letting it set for couple of days, and had to be very careful/gentle so that the paint brush didn't wipe it out of the joint. I was hopeful this stuff would work. Most foam insulation is hard to work with; it over-expands, is very sticky, and you have to use the whole can once you open it. Daptex is easier to work with and you don't need to use the whole can. However, it's too weak, it's like caulking with cotton candy. Not sure I'll use the rest of the contents of the can, even though I could, and I won't buy another. September 30, 2016
Rated 1.0 out of 5.0 by ABSOLUTELY A WASTE OF MONEY Simply look at every review written about this product. 90% of them will tell you the truth. You might as will drive down the road and throw your money out the window . This product failed before I even pushed the nozzle. July 30, 2016
Rated 1.0 out of 5.0 by DONT BUY Don't buy, this product cures to a soft marsh mellow like substance. Does not adhere well to surfaces. I had to remove and use another foam sealant. Tried to review twice and both reviews rejected, hope this one sticks. i wish I had read the reviews before i purchased. September 23, 2016
