Good product
Worked well, good product

Expands well to fill tennis ball sized holes in walls.
It expands to a tremendous degre, so if you have a lot to do I'd advise doing a bit at a time and build up. Otherwise you'll waste an awful lot when you cut off the surplus. Very good for filling external holes in walls that might attract vermin.

Very good
Very good although a tad messy- I’d advise using a pallet knife for a tidy finish.

Messy/nozzle useless.
Nozzle is very ineffective and doesn’t stay in place making the whole process very messy. Have used expanding foam in the past without any problems. Having said that, the foam that I did manage to squirt in the gap has set and done the job. Just need to trim excess blobs.

One Use Only
If you don't use it all in 1 go, you can't use it again, [1 use only] which is ashame as we had quite a lot left in the can. Saying that, the gorilla foam is excellent sets within 24hrs & is as hard as concrete. Its easy to sand smooth but, I would advise a face mask so you don't inhale the dust.
