However, accidents may occur and you may have to remove part of the installed SPF. If this is the case, there are a number of methods that you can use to get remove spray foam insulation. Below are the best tips you can get on SPF removal.

The non-cured materials will wear off in time and depending on the surface you have applied the foam on. You can leave it and allow it time to remove itself naturally.

If the SPF has cured, you need to get stiff-bristled brushes or any other type of rough brush and use it to scrape the foam off. You will need hot water to clean the residue that is left behind after you remove the foam completely.
Use saws for the tough spots

You should also check to make sure that there are no electric lines or pipes that lie beneath the cured Calgary spray foam.
Pry out using older tools

Use acetone in place of water
