Replacing Foam Insulation

Replacing Foam Insulation
Probably the most difficult plumbing repair I have ever completed.
A leak in my spa, under the lounger.
Installing 2" fittings onto, and I use the term loosely, flexible PVC pipe, with a pipe connecting on the back side, in a space no bigger than your oven.
Oh yea, also while laying on the ground!
So I had to pull out some of the original spray in insulation. Would like to replace!
Have seen some 2-part foam kits, about $65 but they are only 1.25 sq ft and I'm guessing I will need 3 cu ft.
In a prior swim spa, I tried to use the arasol spray foam but it would not cling well or fill large areas.
Just looking for ideas/options!

The best can foam I have used is touch-n-seal brand. No-Warp Foam Window & Door Insulating Sealant | Touch 'n Seal
I doubt it's exactly what you are looking for, as you would probably need to apply it in layers, and let it cure before applying another layer... but as far as professional foam go (you need the applicator gun) that are diy friendly, it ranks at the top, imo.
If you wanted to try the mini component kit, here is a link. But 1.25 cu ft isn't much.

Thats the kit I was looking at for $60.
Would need 20 cans for same volume !

After 10 years of spas this is the last one, way too much work to keep them up and running!

I would NOT use the single can type foam. It doesn't handle large voids very well. The type where A and B are mixed together work much better. More expensive, but much better and would be very similar to what was used when your spa was built.

I feel your pain. My first spa I had for 25 years. Great spa but after that long exposed to ozone and chemicals the plastic got brittle. There is almost no plumbing repair on a hot tub that's easy.

I'll pick up one of the AB kits and do what I can.
Considering the spa dealer wanted $80 per hour (3 hours min, two travel, one work) which per my repair took several hours (to do it right) and did not include the reapplication of the foam I guess Im still on the plus side.
BTW, I gladly told that company to stuff it, no way I was going to pay $80 per hour to glue up some fittings. In retrospect it was a lot more work than I anticipated but I bought a special bottle of Tequila to celebrate so everything is very good!

Spa repairs like that are a specialty and the guys that work on them know it. You were lucky you were able to find the leak. It can be quite tedious to dig thru that foam.

What really pissed me off on this was that the spa is only 3 years old ( bought it less than 1 year old) and it had a 5 year plumbing warranty. But despite the original confirmation that the warranty would transfer they renigged on the claim stating since we moved the spa ourselves that if voided the warranty, sorry total bull krap.
Third and last Master Spa!!
