Great quick fix!
[This review was collected as part of a promotion.] This is a great quick fix for cracks or holes around our house. We used it to fill in around where the pipes come through our blocks and the floor/wall of the house. It drys fast and expands to cover the area. I think it is great value for a can and I was able to get every spot I needed filled. I like that I don't have to mix anything and can use one can to get the job done. It also seals air from coming thru and deters critters from wide open spaces. Definitely will purchase if needed again.
Great foam for fixing air gaps
[This review was collected as part of a promotion.] This DAP wall and cavity foam is great for the intended advertised purposes and more! Not only have I fixed air gaps around the house with it, I also refoamed the inside of an old bass boat with it, and this stuff is great, especially with the wide spray applicator. I've used spray foam before with the regular straw applicator, and they're trash compared to this with the wide spray. I'll never buy a regular spray foam again. I'll definitely buy and use the DAP widespread applicator foam from here on out.
Professional quality that can be done ourself
[This review was collected as part of a promotion.] I was gifted the DAP wall and Cavity Foam and immediately put it to use. The insulation is effective and easy to apply, i appreciate its ability to maintain temperatures within a suitable range for heating and cooling systems. Great coverage, and seal ans spray quality. I recommend purchasing an extra bottle to practice. Once you get the hang of it and figure out the proper spray technique, it's easy to use. We successfully used it in a well house to seal the edges on the roof and gaps that the larger bottle couldn't reach. The can contains a substantial amount of product, and when used correctly, it can go a long way. Does an amazing job for the price.
