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.

Is this waterproof?

I sprayed this between my window gap indoors and had some overflow. No problem I carved out the spillage and realized how soft it was. I dripped some water on it and realized that it literally absorbed all the water like a sponge! The can says it it is waterproof - is it and if its not, is it safe to use in my window gaps which have the possibility of getting wet?
Asked by: oepth
No. I found even the dried foam dissolves in water.

Daptex Plus 12 oz. Window and Door Foam Sealant is rated 3.0 out of 5 by 102.
Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from Very poor performance I tried this as a more convenient alternative to the other foams. It started out well - easy application, easy cleanup. But it never cured to any really solid form. There were gaps in the initial foam application that opened after "curing" and then couldn't be filled with additional foam. Even after 3 days it's still soft and crumbly and it feels porous. I finally removed it from the gap I was trying to seal (using my fingers) and went back to the old foam. Job done the first attempt. Note that the job was an indoors leak sealing attempt in a century home. Average temperature was 18C. No moisture. I really can't think of where this product would be useful.

Rated 1 out of 5 by from This the most disappointing sealer I have ever used I used to along my foundation but it never cured. Moisture, temperature who know exactly but even inside the results were similar. Spongy on the outside and wet inside.

The best thing that I can say about this product is that it did not permanently damage anything. It fails at its intended purpose, and you will waste your time removing the failed application. Thankfully, it cleans up easily with towels and water. Even the dried foam dissolves in water.

I've applied this stuff twice, same results. States it's water resistant on the can. Picture shows product after 3 months installed.
