JPH0975877A - Cleaning method for wall surface of building - Google Patents

Abstract

PROBLEM TO BE SOLVED: To clean a wall surface of a building without generating a problem of scattering all over around dust and cleaning fluid by coating the building wall surface to be cleaned with an aqueous temporary protection coating material, peeling off a coating film and cleaning the wall surface. SOLUTION: When a wall surface of a building is cleaned, the wall surface of the building to which dust, fungi, moss, smoke soot, rust and the like adhere is coated with an aqueous temporary protection coating material to form a coating film. After forming the coating film, the coating film is peeled off to remove the dust and the like adhered to the wall surface. An aqueous temporary protection coating material is the one composed of a film forming resin dissolved or dispersed into water, and any kind of such a coating material can be used without restrictions as far as being provided with the required conditions of not infiltrating into a base, not damaging a film during storing and carrying and preventing the film from corrosion, being peeled off easily after achieving the purpose and the like, and a vinyl resin, butyral resin, acrylic resin, polyethylene resin, silicon containing resin or the like is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel method for cleaning a wall surface of a building.

[0002]

2. Description of the Related Art Dust, mold, moss, etc. adhering to the outer walls of buildings such as houses, office buildings, factories and various facilities
As a method for cleaning and removing oil smoke, rust, etc., for example, a physical method using sandblast, power brush, disk sander, scraper, etc., a method of pickling with hydrochloric acid, sulfuric acid, etc., washing with water, washing with a detergent The method of washing, and the method of washing with a solvent such as kerosene or trichlorethylene are adopted.

However, these methods require a great deal of labor and time for the removal work, and it is necessary to take measures to prevent the removed dust and the like from scattering around, and further, pickling and washing with a detergent. However, there is a problem that it is difficult to dispose of the waste liquid by the method described above, solvent cleaning, or the like.

[0004]

DISCLOSURE OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, which is characterized in that a wall surface of a building is coated with a water-based temporary protective paint and is peeled off to clean the wall surface. There is a place to do it.

[0005]

That is, the present invention is characterized in that a wall surface of a building to be cleaned is coated with a water-based temporary protective paint, and the coating film is peeled off to clean the wall surface. A method for cleaning a wall surface.

In the present invention, the building is not particularly limited. Examples include general housing, lodging facilities, government buildings, public facilities, educational facilities, hospital facilities, temples, office buildings, commercial buildings, recreation facilities, factory facilities, warehouses, etc. , Wood, plywood, plasterboard
Examples thereof include a board, a particle board, a concrete, a mortar, a plaster, and a plastic. Those in which paint is already applied to these materials are also included. INDUSTRIAL APPLICABILITY The present invention can be applied to cleaning the inner wall surface, the outer wall surface of these buildings and the surface of ancillary equipment.

The water-based temporary protective paint used in the present invention is known per se, and it has hitherto been known that a coating film is formed on the surface of metal, plastic, rubber products and the like, and mechanical and chemical damage is caused during storage and transportation. It is used for the purpose of temporary protection against rust and antifouling and is peeled off in a continuous film state after the purpose is achieved. However, to date such water-based temporary protective coatings have never been applied to buildings and used to remove their stains.

The water-based temporary protective coating is a coating obtained by dissolving or dispersing a coating film-forming resin in water, does not attack the base material, does not scratch the coating during storage and transportation, does not corrode, and easily after the purpose is achieved. There is no particular limitation as long as it has requirements such as peelability. Specific examples thereof include vinyl resin, butyral resin, acrylic resin, polyurethane resin, silicon-containing resin, polyester resin, and the like, and if necessary, color pigments, extender pigments, dyes and the like can be appropriately mixed.

In the present invention, the water-based temporary protective coating is applied to the wall surface of a building to which dust, mold, moss, oil smoke, rust, etc. are adhered, and the dust is removed.

The coating method of the water-based temporary protective coating is not particularly limited, and may be brush coating, roller coating, spray coating, etc., so that the coating can be applied uniformly to the surface to be coated. It can be arbitrarily selected according to the structure, shape and size of. The coating film thickness is a cured coating film of, for example, 50 μ to 5 mm, particularly 100 μ to
2 mm is suitable.

In the method of the present invention, since various stains of the building are adsorbed on the surface of the coating film of the protective coating,
By simply removing the coating film, various stains on the building can be removed, and the purpose can be achieved.

[0012]

[Advantages of the Invention] Advantageous effects as compared with the prior art are as follows.

1. Since it is only necessary to apply the water-based temporary protective paint and peel it off, the labor and time for the removal work are simplified.

2. Dust and the like are rarely scattered around during the work of removing the coating film.

3. Since no acid, detergent, solvent, etc. are used, their waste liquid treatment is also unnecessary.

[0016]

[Example] Approximately 5 years after construction, water-based acrylic resin temporary protective coating is applied to the porcelain tile and dust-exposed concrete outer wall surface to which dust, dust, etc. have adhered, to a film thickness of 100.
It was coated with a roller so as to have a thickness of μ to 200 μ. When the coating film was peeled off by hand after drying, most of the dust, dust and the like adhering to the outer wall surface moved to the surface of the protective coating film temporarily, and the outer wall surface could be washed cleanly.
