Document Type and Number:
Japanese Patent JPH11514036
Kind Code:
A
Abstract:
A method for removing soiling and graffiti markings from a barrier coat previously formed on an underlying surface is provided, wherein the method preserves rather than sacrifices the barrier coat. The method includes applying a solvent system which includes at least one substantially non-toxic organic solvent such as 1-methyl-2-pyrrolidinone to an area of the barrier coat. A method is also provided to improve the resistance of a protective barrier coat to graffiti markings and other soiling over time and thereby facilitate any necessary cleaning of this barrier coat. The improvement in the case of wax coatings is achieved by including in the wax, at least one protective chemical agent selected from the group consisting of wax-soluble/water-insoluble UV light absorbers, wax-soluble/water-insoluble free-radical and peroxy-radical scavengers, and wax-soluble/water-insoluble wax antioxidants.
