Flattening the foam


For whatever reason, I have a wall in my place covered in the insulation foam ("Great Stuff"). As folks here probably know, this foam dries in unsightly blobs. I would like to get it smooth and flat. For small jobs, I could just cut it with a sharp blade. But cutting with a blade parallel to a wall is tough and getting the entire wall smooth is near impossible. Would a sander do the job? Any other ideas?

Flattening the foam


I've seen people work it with a large hollow rasp. Any solution will probably be messy, but I think a rasp is the most efficient method.

Use an old fine tooth hand saw. This will bend and you can use the two adjoining studs as a guide. Very fast and perfectly flat.

A 6" taping knife should get most of it off. Finish up with sandpaper.

Ditto on the hand saw.
