ABSTRACT:
Oil-based paint containing lead compounds, acrylic-based or other latex paint or a combination of paints in which acrylic-based or other latex paint covers an oil-based paint is removed from a substrate on which the paint is deposited by application of an aqueous solution thereto. The solution comprises a solvent that does not dissolve the oil-based paint and is compatible with water; a film former for retarding evaporation; a viscosity builder to fortify the solution and prevent slumping thereof during application to vertical and overhead horizontal surfaces; an alkaline compound for reacting with the pigment portion of the paint. Advantageously, the solution penetrates the deposited paint, which coagulates and separates from the substrate. Stripping procedures are facilitated, and neutralization of the substrate prior to repainting is avoided. A safe and effective treatment of materials covered with lead-containing paint is carried out in an economical, cost efficient manner.
