We purchased a camper recently and the previous owners attached a screenhouse and quot;sealedquot; the cracks with a spray foam polyeurathane insulation / foamIt turned quot;goldquot; coloredWe removed the screen house and peeled off , to the best we could, the insulation foam from the spray can.however, sticky residue and hardened foam is stuck to the outside of our travel trailerAny product that may remove it? Really hate the thought of sanding it off and then repainting a 3 year old travel trailer!!! HELP!
No - only 100% wool yarn felts (though you could probably get by with like 95% wool.) And wool yarn that is marked 'superwash' won't felt eitherSorry :(
Any solvents strong enough to remove the foam will also attack the paintsorry to say, but thats what is going to happenAcetone will dissolve the foambut it will also strip the paintand it may not be apparent it is doing that, immediatelyYour best approach is probably going to be good old fashioned elbow grease, if you don't want to repaintYou might try scraping the foam off, with a plastic putty knifePLASTIC mind younot metalit will be less likely to scratch the paintA nylon pot scrubber would be another choiceBut the foam may have attacked the paint, depending on which type it was.so you may end up repainting anywayTry the plastic putty knife first.and see what youve gotBy the wayIf that screen room was attached for any length of time, you may have some difference in the paint color, from what was inside it, as opposed to what could be fadedoutside of itGood Luck
