Hi there everyone Im about to make my own diy concrete background.
And have read a few diy articles where they sometimes sudgest using expanda foam
So the other day I went to bunnings and got this Bostik expanda foam but after reading it on the back it says expanda foam should not be immerced in water ????
Does anybody know if this expanda foam will be ok or will it turn my water toxic
and if this is not the right expanda foam what brand should I get
Any information on this would be much apreciated
Cheers Martin
