Spray Foam Solvent

[V153]

What's one to use to dissolve 'Great Stuff' foam sealant? Some knucklehead glued my C500 together with it. Got the deck free from the hull mosta the way around. But the nitwit blasted a tona the stuff up all around a so-called "repair" in the deck.

Acetone? Or will something milder work? Laquer thinner?

Google has some interesting results if you search:

dissolve great stuff foam

None of them had anything much to say about getting rid of cured foam. The minivan that backed over a full can sounded like a nightmare. Can exploded & according to the van driver, it seemed to be snowing...... :laugh: No pix of the van, too bad....

Back to your problem, it sounds like a job for a grinder w/ a twisted wire wheel...............

Sounds like a job for Armstrong Foam Remover (your arm + a sharp cutting tool + manual labor). One of the virtues of urethane foam is that it's not affected by petroleum based solvents, that's why it's OEM and Coast Guard recommended for securing below deck fuel tanks.

W/out pix, I don't know what or where you're having trouble digging the foam out.

A long narrow cheese grater style rasp:

But the wood working version NOT the food version ^^^ :facepalm:
