How to Remove Oil-Based Paint

Skill Level:Novice

Time:About a day (depending on the size of the job)

Oil-based paint is very durable, which makes it the best option for many projects. Unless it is in really bad shape, in most cases you do not need to remove paint to paint the surface it covers. You can scrape and sand the surface and paint over it for a nice looking finish. If it is in such bad shape that it all needs to be removed, you need paint remover. Dry paint cannot be effectively removed with paint thinner. Removing oil-based paint can be easy, without harming the surface underneath with the right method.

Step 1 - Prepare Before Removal

Plan to work outside or in a well-ventilated garage, as you will be working with paint remover, which releases toxic fumes. Lay out the drop cloth for working on the piece.

TIP:Our painting consultant Edward Kimble, author of Interior House Painting Blog, suggests “Working in a well ventilated area is a good idea, but to be safe a respirator is required. I have seen people be overcome with fumes to the point of loss of consciousness.”

Step 2 - Apply Remover

Wearing the rubber gloves, apply the paint remover in a medium coat over the paint. Follow manufacturer's instructions for timing, which is normally 30 minutes to an hour. You will see the paint start to bubble up, which means it is letting go of the surface beneath.

Step 3 - Strip Paint

When time is up, strip the old paint off with a plastic paint scraper and discard the paint in a garbage bag. When all of the paint is removed, wipe down with paper towels to remove residue.

TIP:Edward cautions, “Wet with remover, paint is technically hazardous waste and needs to be disposed of properly. If allowed to dry, the waste can be disposed of safely.”
