Expanding foam.

Hi all!
As i’ve mentioned here many times before i’m making a DIY background.
Will any expandable foam I use be okay? (Great Stuff, Touch n Foam etc isn’t available in the UK)
I’m just using one i found on amazon, I’m going to be doing multiple layers of grout and then using a sealing resin on top so none of it will be exposed at all so I’m assuming it will be okay?
I’m just using Haltons expanding foam filler.

I would think it's made of the same stuff, but I'm just guessing.

As long as you seal it it should be ok

Yes, it will be well sealed, thank you
