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 3.5 out of 5 by 72 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 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
Rated 1.0 out of 5.0 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 5.0 out of 5.0 by Great for specific applications only Great for specific applications but NOT for every application. Holds up to weather VERY well if allowed to set for 24 hours and then painted with a premium latex paint as stated in the directions; I also followed the latex coat with an oil base flat enamel and got excellent weather resistant results with an exterior project, much better than than the exterior caulk that was used initially. I really love GS for some projects, however, I prefer the DAP foam for others, especially when a quick aesthetic finish is desired or required and clean up needs to be a breeze. I used a dry wall knife and got a great seal and sleek look on interior areas, which I later coated with premium latex. When coating with latex paint I found that the brush should be very WET or the foam will stick to the paint and pull away from the bead, although those areas are easily touched up, it can be a time stealer and with a little care, can be avoided. If the user follows the directions on the can it should work as stated. January 29, 2012
Rated 1.0 out of 5.0 by Not "Water resistant" Purchased this stuff without doing my research and I sure regret it. Outer layer of foam formed a dry shell, but inside after a week was still absolute mush. Description says "Water resistant" yet advises to clean up with soap and water. Left a terrible residue that never completely dried after clean up. Save yourself some time and money and go with Great Stuff. Great Stuff produces much more foam per can. The two products don't even compare. Daptex is absolute garbage. January 25, 2015
Rated 1.0 out of 5.0 by Run away from this garbage It only foams after it drips, dribbles and runs. Utterly worthless and ruined a paint job. Buy something else. January 26, 2015
Rated 2.0 out of 5.0 by Not "Great Stuff" Turns into chalk if you touch the cured product. Does not expand much after it leaves the nozzle. Perhaps this is by design, wont swell and warp your project. November 13, 2014
