Hi
we have a lazy spa Helsinki it’s got a pin sized hole in a seam of the main body which I wouldn’t be able to put a patch on, the tub and the air holes have let water in to the liner.
we have had other spa’s in the past and have tried repairing them which doesn’t seam to last.
Thinking of trying to fill the spa liner with expanding foam, which be great for keeping the water temperature. I know it would make it rigid but it never gets deflated it’s constantly used.
just wondering if anybody else has tried expanding foam
And as always it just out of warranty
