ABSTRACT:
A method for accomplishing the above and other objectives has steps of applying a mild solution of acid to surfaces of grout and tile, letting the surfaces dry for approximately 12 hours, applying a grout colorant and sealing material, referred to as grout-treating material, to the grout and such surfaces of tile as the grout-treating material contacts in an application process, allowing grout-treating material on grout and tile surfaces to dry, cleaning the grout and tile surfaces with a non-solvent cleaner and then merely scraping and vacuuming or sweeping the grout-treating material from the surfaces. A small portion of the grout-treating material which might stick to surfaces of some types of tile in the event of errors in applying this method can be scraped off easily or removed with a scrub pad. The preferred acid is 3-to-15 percent oxalic acid in a solution with water. Similar proportions of muriatic acid or sulfanilic acid can be used as substitutes for oxalic acid. A preferred grout-treating material is marketed under the brand name of Lady Dy Colourant and Sealant. Some other solvent-based grout-treating materials also can be used. A kit for using this method has a gallon bucket, a measure of oxalic acid, a tile brush or paint brush, a pair of vinyl gloves and a quart of Lady Dy Colourant and Sealant.
