  • Patent number: 4900364
    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.
