How long does RemovALL take to remove paint?

The best way to determine this answer is to do a test area. Apply the stripper on a small area of your project. This will tell you exactly how the stripper will perform and how long it will take. The time really depends on what type of coating you’re trying to remove and how many layers of paint you’re trying to remove. Coating removal time will vary anywhere from 2 to 24 hours.
