Title: Refoaming a Repair
Post by: rosewoodsteel on December 10, 2013, 07:48:30 am
Question-  Can you use spray foam "in a can" to replace dug out insulation after a repair?

I'm not 100% sure, but it does look like the same stuff they use from the factory, just larger cans.  ;)

I think i'd agree with SR. It looks and feels like the same stuff.
I guess the only difference is theirs will be mixed on site by the gallon, ours will be in a tin ready mixed.
If i were replacing the foam, this is what i'd use.

Take a peek inside your spa cabinet...can you add some insulation? We recommend foil-faced bubble-wrap, available at most home improvement stores. It's waterproof, cuts w/ scissors, staples/stuffs in and is R3 per 1/4" (the 'double-bubble' is the best)

There are kits available which are two-part foam. Mixes in the spray nozzle and springs to life. That is what the factory sends me to refoam a tub after any repair or rat damage.

It isn't cheap! I would not be surprised to find that it is available from other sources for less - check it out. The factory part number for a small kit is 70293, does about two or three cubic feet.

There is a much larger kit available -

part number 70869 -which does a huge amount of foam. They list it as eight cubic feet, but I have gotten much more than that out of it.

Be careful with any foam product you use: it can get on your glasses and ruin them, the fumes are bad to breathe, and it MUST be used in warm temperatures only.
