Removing Foam from an Engine Box

[Sam_Steele]

I am replacing engine noise insulation with some new fire resistance insulation and so I set about ripping out the old foam. That was the fun bit...now I am left with a thin layer of foam stuck to the inside of the wooden engine box. I have tried removing it..
Using a knife - still leaves a residual amount which I can sand off - but takes ages
Using a sharp scrapper....very slow and not much good.

Any other ideas that would remove it quicker

You culd experiment with your 'offcuts' and see if you can find a suitable solvent - but beware of fumes and any action on fibreglass...

And under the residual foam lies the real fun - the glue. If what's left now is anywhere near an even surface I'd leave it in place and put the new stuff over it.

It's not really even - but I wondered about sticking/screwing a thin sheet of plywood to it if the solvent idea doesn't work. The glue did seem a night mare to sand

I was wondering about a solvent...any ideas as to which one?

if its foam. its polyuerophane based and theres almost nothing to disolve it without going over to chemical war.
its a good a base as any to glue on once the powdery stuff is sanded away
consider it a primer

I've had some limited success with a small hand held curved surform. It's like a baby cheese grater and the holes are so coarse it's very difficult to clog them. It might leave a few gouges in your wood but it might just even things up enough for you stick the new sheets over it.

I recently replaced the foam on our Sigma with a modern fire resistant laminate. I agree with Anchorite, rough it down and then glue on the new stuff. If you really want to use a solvent then try acetone but use all sensible protective/safety measures.

Hi Anchorite,

You were so right - the foam was the easy stuff it was the glue that was the problem - so i resorted to what you said and it worked....thanks
