Specifically, the present invention provides an aqueous solution for treating materials, such as wood, metal, masonry, brick, and composition oil paintings board, which have been covered with lead based paint, to remove the paint therefrom. Briefly stated, the solution comprises a solvent that does not dissolve the paint and is compatible with water;
A film former for retarding evaporation; a viscosity builder hand-painted oil painting to prevent slumping during application of the solution to vertical and overhead horizontal surfaces; and an alkaline compound for reacting with pigment containing portions of the paint to loosen any crusted lead compounds, or other pigments, present on the surface thereof. Such crusted lead compounds oftentimes remain on the surface of aged paint following erosion of the original vehicle by oxidation and weathering.
It has been discovered that problems heretofore cheap oil paintings encountered with solvents conventionally used in paint removers are overcome by use of a low volatile, relatively safe solvent, together with additional ingredients, as described hereinafter. One such solvent is known to be a coalescent or solvent in acrylic latex paint, but is not known to be a solvent for the vehicles used in oil-based paints. That solvent is ethylene glycol monobutyl ether.
