Description

TITLE OF THE INVENTION
Coating Compound For Resurfacing Damaged Wall/Tiles And The Method Of Using The
Same FIELD OF INVENTION
The present invention related to coating compound for renewing and resurfacing in tile or wall. More particularly, the present invention relates to renewing and resurfacing damaged wall/tile and floor structure. The present invention also relates to a method of applying the coating compound on damaged wall or tile. BACKGROUND OF THE INVENTION
For wall or wall tiles used in commercial and residential buildings, the wall tiles are easily broken, cracked or damaged, and need to be either replaced or resurfacing after a long period of use. Sometimes, a person may no longer like the design of the wall tiles and may wish to change to a desirable design. Thus, these wall tiles need to be either removed or coated with some other design on the surface of the damaged wall tiles. The conventional method of removing the damaged wall tile is rather time consuming, requiring a lot of patience and effort. At times the wall tiles cannot be removed easily, heavy machines are needed and the structure of wall may be affected. Accordingly, a need for a wall resurfacing remains so as to efficiently replace the design of the wall. An example of wall tiles that need to be resurfaced for instance are wall tiles of most toilets of the commercial buildings. The wall tiles always remain dirty especially the grooves between the tiles or the filt joint. This has led to a very intensive cleaning using chemicals with corrosive characteristics. These chemicals are generally harmful to human body and therefore it is a hazard to the cleaners. US Patent No. 5,620,768 issued to Hoffman A three-layer surface repair patch assembly for covering a hole in a wall under repair, the assembly comprising: a deformable yet relatively rigid sheet means, the sheet means having an inward-facing side and an outward -facing side, both sides of the sheet means being free of adhesive prior to engagement of the sheet means with an inner and outer mesh means, the inward-facing side of the sheet means remaining free of adhesive after engagement of the sheet means with the inner and outer mesh means, the sheet means being disposed between the inner mesh means and the outer mesh means, an inward-facing side of the inner mesh means being coated with pressure- sensitive adhesive material for instantly adhering to the surface to be repaired under manual pressure, an outward-facing side of the inner mesh means being free of adhesive, an inward-facing side of the outer mesh means being coated with pressure-sensitive adhesive material for adhering to an outward-facing side of the sheet means and for adhering an outer margin of the outward-facing side of the inner mesh means under manual pressure, the inner mesh means includes an outer margin disposed between an outer periphery of the sheet means and an outer periphery of the inner mesh means, the outer mesh means includes an outer margin disposed between the outer periphery of the sheet means and an outer periphery of the outer mesh means, the sheet means being held in place when the assembly is attached to a wall by adherence of the sheet means to the inward-facing side of the outer mesh means and by adherence of the outer margin of the outer mesh means to the outer margin of the inner mesh means, no pressure-sensitive adhesive material migrates from the inner mesh means to the inward-facing surface of the sheet means, no pressure-sensitive adhesive material migrates from the outer mesh means to the inward-facing surface of the sheet means, the assembly being held in place when the assembly is attached to the wall by adherence of the inward-facing side of the inner mesh means to the wall.
US Patent No. 5,075,149 issued to Owens et al discloses a three-layered patch with a metal plate disclosed between two polyester sheets. The metal plate is held in place between the two polyester sheets with a semi-solid adhesive such as urethane. The semi-solid adhesive fixedly attaches the two polyester sheets together as well as fixedly attaching the reinforcing metal plate between the two sheets. Owens is not useful for repairs which require the application of bonding material or plaster to the repair patch because the bonding material or plaster cannot readily pass through the mesh due to the presence of the urethane adhesive.
US Patent No. 7,716,893 issued to King Harry discloses a wall resurfacing kit for allowing users to quickly and easily resurface a damaged wallpapered surface, said kit comprising: a plurality of mesh screen sheets, said plurality of mesh screen sheets being made of fiberglass and further being directly attachable to said wallpapered surface; a reinforcing member being applied directly onto said plurality of mesh screen sheets such that said reinforcing member penetrates through said plurality of mesh screen sheets, wherein said reinforcing member directly couples said plurality of mesh screen sheets to said wallpapered surface; and a set of instructions indicating a decoration mode, said decoration mode being used to decorate said wallpapered surface; wherein said plurality of mesh screen sheets are coextensively shaped and offset from each other when applied to said wallpapered surface; wherein said mesh screen sheets are arranged in an offset pattern so that a first pair of outer edges of each said mesh screen sheets do not over-lap while a second pair of outer edges of each said mesh screen sheets over-lap when applied to said wallpapered surface.
US Patent No. 4,370,363 issued to Peter Schulz discloses a method for glazing the surfaces of silica bricks used in coke ovens, which comprises forming a suspension of water-glass powder and glass powder in a concentrated water-glass solution, applying the suspension in solution to the surfaces of silica bricks, drying said bricks, and then baking said bricks to form a protective layer which will prevent the penetration of liquid and gaseous substances into the brick. US Patent No. 4,370, 363 also discloses a coating compound for silica bricks, particularly silica bricks intended for use in the construction of pitch coke ovens, where it is necessary to protect the bricks against penetration of liquid and gaseous substances and impede the formation of graphite incrustations.
US Patent No. 4,122,225 issued to Holmstrom et al discloses method for coating tile having an exposed decorative surface subject to wear including high areas subject to greater than average wear and low areas subject to less than average wear comprising the steps of: providing a plurality of base tiles, each tile having pre-formed front, back, and side edges, in a continuous succession with the front and back edges of adjacent tiles abutting one another; while said front and back edges are abutting, spraying a first coating of protective material onto said exposed surface from one or more points vertically within said preformed side edges so that the exposed surface shadows said side edges from the spray; at least partially curing said first coating; applying a second coating of protective material primarily onto the high areas of said exposed surface; and curing the protective material. US Patent No. 4,122,225 also discloses a coated tile comprising a base layer having a decorative exposed surface having high areas and low areas defining said exposed surface, and disposed upon said exposed surface of said base layer a coating of protective material which has an average thickness on the high areas of the surface of said base layer which is greater than the average thickness on the low areas of said surface.
