Below is some information you need to take into account before you start up your power sander or heat gun. For bigger sanding jobs, you'll want to use a power sander. Belt, disk or drum sanders can be used. Although sanding removes a painted surface quickly and easily, it has one basic disadvantage - it also removes some of the wood surface underneath the paint. If you are working on a fine piece of furniture, sanding is not recommended.
Fine sandpaper clogs up quickly, making it ineffective as a paint remover.
Chemical paint removers are much more effective and easier to use. Special electric paint removers or heat guns use heat for paint or varnish removal. Scrape away the paint immediately after it is heated. Use a broad paint scraper for removing the heated paint right behind the electric softener. Keep moving often to avoid browned or darkened spots on the surface from excessive heat.
