DIY spray insulation

[CarolWilks 0]

I’m considering spray insulating the sill areas between the floor joists. I had watched a YouTube vid and it looked simple enough. Was looking at the DAP product for this.
I was wondering if anyone here has done this, and was there any issues with fumes? And should I wait until warmer weather to tackle this, when ventilation will be less of an issue. Any constructive input welcome.

Thanks in advance,
Mike in Maine.

Your plan for ventilating and using a respirator is right. Froth paks can be frustrating when they clog, so having extra space ready helps. If you later decide to insulate the attic too, I found a handy online calculator that answers how many bags of blown in insulation do I need without guesswork. It sized my job perfectly, including settled depth and bags.
