Abstract
A method for stripping cured paint from a surface using a stripper composition containing a caustic alkali and a film forming liquid coating which is sprayed on the stripper composition to form a film on the surface of the stripper composition, the liquid coating containing a volatile thinner and a parafin formulation or a liquid vinyl-solvent, the coating being separable from the stripper composition to allow for removal of the composition and softened paint by scrapping or washing with a high pressure water wash. A further method is to mix a solvent free liquid vinyl coating with a stripper composition and an additive to form a homogeneous mixture that can be sprayed onto the cured paint and removed by peeling to remove the softened paint.
Claims3
A method for stripping a cured surface coating of paint from a surface, said method comprising the steps of:
- applying a potassium hydroxide stripper composition to the cured surface coating of paint,
- spraying a clear liquid-vinyl film over the surface of the stripper composition to form a thin vinyl coating on the surface of the stripper composition to prevent drying of said composition,
- permitting said stripper composition to react with and decompose said surface coating of paint,
- peeling the vinyl coating from the surface of said stripper composition, and
- removing the stripper composition and coating of paint from the surface by scraping or spraying water under pressure on said stripper composition.
