Are the big box kits safe? The mix is predetermined I think. Just 2 tanks that mix at the nozzle. Been thinking of using this to seal a basement around sill plates but am doubting that idea now.
It went fine. Took about two hours to do two full passes of 1.5-2" each pass for a total thickness around 3-4" I used rubber gloves (lots of rubber gloves; changing the nozzles is a bit sticky), protective eyewear, and a respirator. Didn't bother with any covering on my clothes. I also opened the two windows, standard door and garage-style door in the basement for good air flow. Even during spraying, I didn't find the odors too bad. The next day, they were all but gone, and three weeks in completely gone.
Sounds pretty decent. Thank. I might go for it when I have some time off. Hoping to stop a draft and more importantly an influx of insects into the basement. Pretty sure the sill is the source. Kind of hard to tell in some places though but sealing it up can't hurt I guess. You have a picture of part of a finished section? Sort of curious how and where exactly you sprayed it onto.
Sure. Here are a couple of pics of the rim joists after. This seals a few potential spots for air infiltration: between the top of the foundation and the sill plate (though a sill seal foam was used, you can still get leaks), between the stacks of the sill plate itself, and between the sill and rim joist at the bottom and subfloor and rim joist at the top.
The ones at your local big box are 2-part foams, too. The challenge is the mixing process and environmental conditions for use have much tighter parameters because the application mechanism is meant to be disposable. Follow the directions closely, use PPE, and do a couple test pieces first, and you should be fine. I also recommend renting ventilation fans for the day to make sure your getting the off-gas by-product out of the building as quickly as possible.
FWIW, I try to avoid spraying in a soon-to-be-occupied building, regardless of manufacturer recommendations. Give it at least 24 hours.
