Beware: 30 seconds almost too much ...bag expanded quickly and blew before getting completely in the hole, spraying on shoes and legs a bit..even shot thru between fence a bit..WOW...I would say at 20 seconds quit and start cutting open bag..NOW to get crap off skin, read the warnings as well. I think I will stick with my old construction ways next time..LOL

Hmmm, was thinking of using this for 3, 10ft 4x4 posts to hold up string lights. Not sure it will stand up to the strain of the wire between the house the the posts. Planned to put them 2 ft in ground, so needs to hold 8 ft. Was also going to use those pointed post braces on the base in the ground. Should I use concrete instead? Is this application considered "structural" - as they mention in the video?

I see you didn't mention price. Foam $20.00 a bag, concrete $4.50 a bag. If your setting a fence with 15 poles that's quite expensive.

Used some today and just looks like foam out of a can. I’m wondering if it’s going to turn orange and get brittle?

I'm starting to think s good ol bag of concrete sounds a lot easier. We'll see I'm going to try it now.

Should have been more suggestions on use like squaring, up lifting a few inches out of hole before pouring etc

I use it to make targets Just pour in a halloween mask.

Looks to be little more than expanding foam, which is not known for its structural strength.
