Abstract: There is provided a one coat system. The system, among other benefits, encapsulates lead paint, encapsulates and covers existing graffiti, prevents the leaching out of the harmful lead paint salts and graffiti from the encapsulated areas, and prevents the penetration into a substrate of future graffiti. The system includes a film forming mixture and a curing and activator mixture. The film forming mixture has a water based epoxy group of components, a water based polyurethane solution, a solvent based polyurethane group of components, and an oil based additive. The curing mixture has a water based epoxy group of components and oil ester based, iso-cyanate free, catalyst-curing agents. The film forming mixture is between about 93 and about 105 parts by volume of the system. The curing and activator mixture is between about 76 and about 83 parts of the system.

Abstract: A cleaner composition for removing graffiti including ink, marking pen marks and paint from a variety of substrates or surfaces. The base composition for all five embodiments comprises N-methylpyrrolidone, propylene carbonate, isocetyl alcohol, an ingredient selected from the group consisting of dipropylene glycol monomethyl ether acetate and dipropylene glycol methyl ether acetate, a thickening agent and a surfactant. Each species or embodiment varies the range of these ingredients and some embodiments include other ingredients, such as dimethyl sulfoxide, a tertiary amine and mineral oil and lavender oil. Each embodiment is directed to a different type substrate or surface to maximize the removal of graffiti on that surface without any deleterious effects to that surface.

Abstract: The present cleaner removes graffiti, paint and other coatings, if any, from a surface. The cleaner comprises N-methylpyrrolidone; propylene carbonate; hydroxy propyl cellulose thixotropic thickening agent; an ingredient selected from the group consisting of diethylene glycol monoethyl ether acetate, dipropylene glycol monomethyl ether acetate, dipropylene glycol methyl ether, diethylene glycol ethyl ether and isocetyl alcohol; and a surfactant.

Abstract: A system and method are provided for treating a surface to both cover existing graffiti thereon and to facilitate removal of subsequently applied graffiti. A two part, water-based epoxy is initially applied to the surface. After drying thereof, a top coat system including an aliphatic urethane color component, a catalyst and a hardner is applied directly over the epoxy and permitted to dry. Upon drying, subsequently applied graffiti may be easily removed by the use of a solvenated cleaner.
