Spray Foam

We purchased a camper recently and the previous owners attached a screen and "sealed" the cracks with a spray foam insulation polyurethane / foam. It was "gold" color. We removed the screen house and peeled, better than we could, the foam insulation of the bomb ... However, sticky residue and hardened foam is stuck to the outside of our travel trailer. Any product that can remove it? Really hate the thought of sanding it and then paint a travel trailer for 3 years! HELP!

Any solvent strong enough to remove the foam also attack the paint ... sorry to say but thats what will happen.

The acetone will dissolve the foam ... but it will also remove the paint ... and may not be apparent because it immediately.

Your better approach is probably going to be good old fashioned elbow grease, if you do not want to repaint. You could try to scrape off the foam with a plastic putty knife. plastic mind you ... no metal ... it will be less likely to scratch the paint. A nylon pot scrubber would be another choice. But the foam may have attacked the paint, depending on the type it was .... if you can find repaint anyway. Try the plastic putty knife first ... and see what youve got.

By the way .... If this play was the screen attached for some time, you can have some difference in the color of paint, what was inside, contrary to what might be faded ... outside it.

Good Luck

While exact wording of the expanding foam will help. Or similar products available in any store in the house ... Then the solvents can help, but no matter what you try, you might still assume that the paint job is already, or will be damaged.

Cut the foam with a knife or a saw. On a sheet of placing one or two drops of nail polish remover (acetone). The foam should dissolve. Also, try lacquer thinner. It should do the same thing. Both can be obtained in larger quantities at a paintstore or WalMart. When it comes to the sticky stuff, scrape as much as possible to the surface and dampen a cloth (which has happened) and wipe off the goo (do not wear heavy rubber gloves). It depends on the paint job on the trailer (if it is baked on enamel on metal) of your chance to dissolve with either product is reduced.
Be fully aware of these products are flammable and you need to do this work outdoors.
Paint the foam that shows the end product with a 100% acrylic latex for exterior.

I would use WD-40. Spray it on a small area and let it soak in a scrubber and then use nylon (like you use on the dishes) to get rid of the loose foam. After getting clean, use a paste wax to seal the area to prevent oxidation.

You may want to ask someone at the hardware store where you bought what to use, I would try Goo Gone or Goof Off .. this could take some of the paint too, but you can try this option if you remove some of the paint,,, strips off around the area where the paint was removed (around the screen Internal) painting small area, almost the same color, or use a different color to emphasize it, no need to paint the camper together, it will probably look good, you can always paint over it, if you do not like the color

My lighter do. Better to first try a small spot Good.
