What is the most common method of chemical stripping for paint removal?

The most common method of chemical stripping for paint removal involves using a caustic lye solution. This approach utilizes alkaline solutions that effectively break down the chemical bonds in paints and coatings, allowing for easier removal of layers. Caustic lye is particularly useful for removing multiple layers of paint and works by saponifying the oils in paints, thus softening and loosening the paint film for easier scraping or washing off.

Chemical strippers are favored in many scenarios because they can be more efficient and less labor-intensive compared to mechanical methods. While acetone can act as a solvent for some types of paint, it may not be as effective for all coatings and can evaporate quickly, limiting its effectiveness. Sandpaper and heat guns are mechanical methods that can be used to remove paint but often require more physical effort and may not offer the same level of efficiency for thicker layers or specific types of paint as chemical strippers do.
