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.

Rated 3.3 out of 5 by 78 reviewers.
Rated 4.0 out of 5.0 by Does what it says. I like this product. It is certainly different than the solvent based products. Much softer when dry with the consistency of a loaf of soft bread. I used both the DAP and other products on my project with different results. The project was overhead, filling gaps behind the HVAC registers and tapering for smoother airflow. It was also to keep out bugs that crawl through the cracks. The DAP foam was much easier to apply and stayed where I put it. Though its not sticky, when you apply it, it stays. The other product wanted to fall out, and then trying to caress it back in place didn't work as it then stuck to whatever I was using to try to push it back up. As the project was overhead, the DAP worked better as the can does not need to be held upside down like others. It does take longer to dry (two days for me), but once dry provided a finish like the top of baked bread instead of the lumpy bumpy finish of the other. But the DAP is not as structurally sound once dry. You can easily poke a finger into it or pull it out. I'd estimate that its about 4 times softer than a solvent based product. If you need sturdy, you're better off with something else. It tooled fine once dry. But let it dry completely or you'll make a mess. Water cleanup was great. No need for acetone. Overall, I'd like to see this stuff dry up to a sturdier end product, but it seems to be holding up fine so far. February 18, 2013
Rated 1.0 out of 5.0 by Only lasts five years The 5 yr. expected lifetime of this product is much less than many other foam sealants. While the use of an open-cell foam may have advantages, the labeling does not make clear how relatively weak the seals will be using this product. August 24, 2015
Rated 1.0 out of 5.0 by Bad product ever Horrible product. Wait 24 hours, it is still not set up. Can I return product and get my money back? November 1, 2015
Rated 3.0 out of 5.0 by Easy to use but does not set hard I have used this on my new front door and basement windows. With the front door, I ran out of big gap filler foam and picked this up in a rush. Weather was dry and in the mid-seventies. It did not perform well in large gaps and much of it was still not set when I put the brick molding back on. Because it sets slowly, gravity pulls the foam down the large gaps and it oozes at the bottom. So, you are left with no foam up top and more foam oozing at the lowest point. I had to re-spray a few times. It has ~50 years to dry now or I made a mistake. I used this later on my basement windows as the instructions call for a 'low pressure' foam. As the other brand expands 50% and this product only 10%, I went the Daptex again for these smaller gaps. I foamed the jambs of the windows easily and crimped the nozzle to get above the header and below the sill. Weather was in the 80s and humid; the foam dried within 4 days but not to a really hard consistency. The other brand sets to a hard rubber-like consistency while this one to a 'cupcake' as another reviewer put it. Since I installed the windows, my basement has been noticeably more insulated. Probably a combo of both the foam and windows. We'll see how the winter goes. What I do like about this foam is how re-usable the straw nozzle is. The other big brand of foam dries quickly and you have to use the whole can in one go. With the Daptex foam, I can put tape over the nozzle and use it days later. Especially with the basement windows which all six took two weekends to install, I used one less can than I would have. The foam is also much easier to clean and remove than the other big brand.

Rated 1.0 out of 5.0 by Horrible Product I am usually not one to bash a product but I tried it twice and both times ended up very frustrated. It doesn't set up well enough and both times the top applicator part came out and wouldn't go back in. The material comes out everywhere and about 3/4 of the can was wasted. Do not buy!

Rated 1.0 out of 5.0 by Sets up like milk foam Waited 24 hours per the instructions and it did not set up. Still had the texture of milk foam throughout. Put my tools in the dishwasher because label said water soluble clean up. It polymerized and ruined all my tools. August 29, 2015
Rated 5.0 out of 5.0 by Perfect sealant and insulator. I wouldn't use anything else for sealing gaps. Low expansion (about 10%) means nothing gets pushed or warped, and nothing will leak out the sides; it stays where you put it. It's non-adhesive, so it cleans off of finished surfaces easy without staining. After setting, you can scrape excess away with just your fingers, leaving a nice even surface that won't block molding and can be painted. If you're concerned about spray foam affecting appearance, this is perfect for the job. Like the label describes, this does not an adhesive, expand to great measures, or have structure. It's simply a clean and workable foam sealant. To the persons that gave this a low review: Have your requirements and expectations straight when choosing a product, and read the label. If you require a product to expand, have structure, or be an adhesive, then buy a product that does that. Read, ask, learn, then pick the right tools and materials for the job. April 7, 2011
Rated 2.0 out of 5.0 by Be careful where you use it Pros: - Easy to apply, expansion is gentle and controlled - Low odor - Easy cleanup Cons: - After 48-hours @ >60 degrees F a 1/2" bead of Daptex Plus had the consistency of a cupcake. I dug it out effortlessly with my finger. Recommendation: - Probably fine within cavities, otherwise use something harder. April 21, 2012
