If a painted surface is clean and in good shape, you can usually paint over it without removing the old paint. But if the old paint is broken, peeling, blistering, or otherwise loose, painting right over it is a bad idea. At first, the new paint will cover up the flaws, but it won’t be long before the layer underneath bubbles up and makes your work look bad. So, to get a good base for your next color of paint, you’ll need to spend some time taking off the old paint.<\/p>\n
Most of the time, a wire brush, a paint scraper, or a combination of both are used to scrape paint. This can be hard to do and take a lot of time. If you want, you can just work on the spots that aren’t perfect and then sand the surface to make it smooth. But if you want the smoothest finish, it’s best to get rid of all the old paint first.<\/p>\n
