Stripping away of old finish:
1. Mechanical stripping:
This involves using sharp blades or scrapers to physically lift the old finish from the wood surface. Depending on the material, the application of a stream of hot air from a heat gun as the surface is scraped may facilitate the removal of the existing finish. The other mechanical method for removing an existing finish is to use abrasive materials commonly referred to a “sand paper.”
2. Chemical stripping:
There are many chemical compounds sold as paint strippers or finish removers. Most of these contain Methylene Chloride or N-Methyl-2-Pyrolidone (“NMP”) as an active ingredient. These compounds are generously applied, usually by brush, over the existing finish and the adhesion between the wood and the finish will be broken. If the existing finish consists of several coats, multiple applications may be required.
