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 3.6 out of 5 by 69 reviewers.
Rated 4 out of 5 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 2 out of 5 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
Rated 1 out of 5 by What would you use this for? In the process of remodeling 100 year old home. While replacing windows, I thought I'd try this product. It was 2-3 times the price of GS, but was water based and looked like a good yield per can. I bought 4 cans. The only good things I have to say about this product is that it's easy to clean up and has virtually no odor. It has the consistency of whipped cream and skins over, but never really "sets up". I can imagine it getting blown out if you get any pressure behind it. The can says the yield is 510 feet of a quarter inch bead, but if you can get that out of it, you are a magician. It comes out of the can very slowly and only for about 10 seconds- then you have to stop and rinse the tube and nozzle out with hot water. I only got half-way around a standard 32x46 window before I finally put the can down. I'm going back to Great Stuff Window and Door. I can't see this product being good for any application. Don't waste your money. I'm taking 3 of my 4 cans back. October 24, 2011
Rated 1 out of 5 by A very poor product Granted, this product is supposed to remain soft after curing, but considering it will not cure at all makes it worthless. What little does "cure" remains too soft to take a coat of paint and crumbles at a touch. I was very disappointed in this product. June 2, 2014
Rated 1 out of 5 by Disintegrates when you touch it This stuff says on the label "For exterior applications, foam must be painted with a quality latex paint after fully cured." Well, I just let this stuff cure for over 30 hours and tried to paint it... it disintegrates into a white powder with the lightest touch. I can't get any paint on it, it crumbles as soon as the paintbrush touches it - this stuff is completely useless, I'm going to have to scrape it away and start from scratch. December 28, 2013
