What Customers Are Saying

Customers praise the product for effectively sealing gaps and improving energy efficiency, with many reporting noticeable temperature control improvements and easy application. The wide spray applicator and expansion properties are frequently highlighted as key strengths. However, a notable minority report serious adhesion failures on vertical surfaces, with foam sliding or falling off despite following directions. Several also express frustration over coverage claims not matching actual performance and inconsistent propellant pressure. While most find it effective for small to medium projects, adhesion issues and perceived overpricing concern some users.

Don't Bother

Would Not Recommend

This product is a very poor option and did not perform anywhere close to what I expected from reading the DAP product description and application guidance.. I've since covered the whole mess with unfaced insulation that actually works as advertised. Of course, I expect application errors to be blamed and there to be nothing wrong with the product.

Followed directions to the letter

Would Not Recommend

Followed all directions to the letter, made sure the surface of the OSB was clean and dry, the temperature was correct for air and surface, shook the can like instructed, attached connections, and started spraying only about 1/2" thick...then got to listen for 15 minutes as the foam expands and fall off the wall to a slop on my floor. Trash product that did little more than make me waste $200 and leave a mess to clean up. Thank DAP for another trash product and zero hope for you to resolve othe...

I won’t waste your time with another long review. Everyone seems to nail it on quality. I will just say…”YOU GET WHAT YOU PAY FOR”. DAP is a good company, BUT I think you may want to rethink this product.

I wouldn't recommend this crap to my worst enemy.

Would Not Recommend

This is the worst stuff I've ever dealt with and I wish I had a time machine so I could buy the real 2-part stuff from the beginning. It comes out sputtering and clumpy and barely covers 50 board feet, not the 95 it advertises. Do yourself a favor and buy the real 2-part stuff first so you won't have to spend EVEN MORE money attempting to fix the first pass. I am so angry that DAP would even think to sell this nonsense. Their 2-part kit is just so much freaking better.

Not so great

Would Not Recommend

I have used many two part foam kits with good results. Yes this will seal and stick to about anything. I needed to cover 90 bd ft and needed two kits to get it done. The sprayer provided with the kits is clumsy to use. Foam was slow to cure. Just plan on half coverage and you will be fine.

Worked as expected.

Would Recommend

Follow the instructions, it comes out fast so test it before hand. It is a bit messy, but east to clean up after it sets if you protected areas. Everything in one package, get a mask this stuff has a strong smell till it sets up.

[This review was collected as part of a promotion.] Easy to use but not really work well.. permanent seal the wall and tiny hole but easy to fall down and not stay. Keep falling off even if re-apply many times
