Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a covering method for securing a covering on the wall surface of a building and preventing the occurrence of cracks.

Conventionally, methods for covering walls include pasting wallpaper or applying organic or inorganic coating materials.

However, the current situation is that such methods cannot prevent cracks in the underlying wall surface, or even strengthen cracks that have formed in the old wall surface.

There is also a method of pasting tiles or decorative plywood, but these are expensive and time-consuming, so there was a need for a mounting method that was easy to install and had luxurious and sophisticated performance.

As a result of various studies in order to eliminate the drawbacks of Narijo, the inventor of the present invention has found that when applying a coating base material made of glass fiber fabric to the wall of a building and then applying a coating material to the surface, The present invention was completed by discovering a new fact that the disadvantages of the above can be eliminated.

According to the method of the present invention, it not only strengthens old cracks in the wall, but also suppresses the occurrence of new cracks, and even if some cracks do occur, they have the effect of hardly affecting the surface. It is something. Moreover, the effects of the present invention are not limited to this, as the coating base material made of glass fiber is flame resistant, so it is resistant to fire, and it is also highly safe because it does not generate toxic gas even when heated strongly.

It also has excellent abrasion resistance, impact resistance, and chemical resistance, and is resistant to moisture, making it suitable for use on walls in bathrooms, kitchens, etc.

As the glass fiber fabric serving as the base material for coating, any suitable weave such as plain weave or twill weave can be used, and the thickness of the fabric is not particularly limited.

Although such a glass fiber fabric can be used as it is as a base material for painting in the present invention, even better effects can be obtained if it is treated with a resin such as impregnated or coated with a resin.

That is, in the present invention, when adhering a glass fiber fabric to the wall surface of a building as a base material for painting with an adhesive, if the glass fiber fabric is used as it is, the adhesion may not be sufficient, but if the glass fiber fabric is used as it is, the adhesion may not be sufficient. By using , sufficient adhesion can be achieved.

Furthermore, the walls of buildings are usually made of concrete or cement-based materials such as cement celtal. Therefore, when the cement wall surface is new, the glass fibers may be corroded due to their alkalinity, but the resin treatment imparts alkali resistance and prevents corrosion.

This has the advantage that cement-based adhesives and coating materials may be used.

Furthermore, the resin treatment prevents the woven fabric from becoming loose, and especially when it is a plain weave, it prevents the stitches from shifting. This contributes to improving the paintability (ease of painting) in the painting process, and has the advantage that no misalignment occurs during the painting process.

The resin used for resin processing of the glass fiber fabric may be a solvent solution, an aqueous solution, or an aqueous dispersion of a thermoplastic resin or a thermosetting resin. Examples of resins include polyvinyl acetate, polyvinyl chloride, polyacrylic ester, synthetic resin, polyester resin, phenol resin, urea resin, melamine resin, starch, and glue.

Adhesives for attaching glass fiber paint base materials to the walls of buildings include solvent solution adhesives, aqueous solution adhesives, or aqueous dispersion adhesives using thermoplastic resins or thermosetting resins. Any of these can be used, and inorganic adhesives such as cement can also be used. Examples of adhesives include polyvinyl acetate emulsion adhesive, polyacrylate solvent solution adhesive, epoxy adhesive,
These include rubber adhesives, methylcellulose adhesives, starch adhesives, white cement mortar adhesives, and resin-containing cement mortar adhesives. Further, the adhesive may be attached using an emulsion paint, a solvent-based paint, or a combination thereof with the above-mentioned adhesive.

Any coating material such as organic, inorganic, emulsion, water-based, or solvent-based can be used as the coating material to be applied to the surface of the glass fiber paint base material attached to the wall, but emulsion paint or A resin-containing cement thread coating material is preferably used. Such a coating material may be applied directly to the surface of the base material for painting, but it is also possible to apply an adhesive containing an adhesive to the base material for painting in advance, and then apply the coating material.

M-type GEL can be applied by brush, roller, or spray, and may be applied once, but it is better to apply it twice.

Next, the present invention will be explained in detail with reference to Examples.

Example 1 Thickness i made using glass fiber filament with a diameter of 7μ
Glass fiber fabrics made of plain weave rovings of mm and 2 mm were adhered using polyvinyl acetate emulsion to an old cement mortar wall that had several cracks with a width of 1 to 6 mm and a length of 10 to 200 mm.

After drying, a white emulsion paint was applied to finish.

As a result, the old wall with cracks was beautifully finished, the cracked areas were reinforced, and the wall was able to withstand the impact of a hammer.

Example 2 The same glass fiber fabric used in Example 1 was immersed in an ethylene-vinyl acetate copolymer emulsion and dried.

This resin-treated glass fiber fabric was pasted on the wall of a new cement mortar using an ethylene-vinyl acetate copolymer emulsion, and after drying, a cream-colored alkyd resin + TV F& material was applied to the surface. As a result, 6
Even after several months had passed, there were no changes such as floating or peeling.

On the other hand, when a glass fiber fabric was pasted on a wall without being coated with resin and alkyd resin paint was applied in the same manner as above, after 6 months, glass FRm fabric was attached.
The material was attacked by the alkali of the new cement mortar, becoming thinner and having poor adhesion, and floating in several places.

Example 6 The resin-treated glass fiber fabric used in Example 2 was mixed with ethylene-vinyl acetate copolymer emuldimine at a solid content of 10% of the cement on a wall made of cement mortar. A cement paste prepared by kneading with fine aggregate was applied to the surface, and before it was sufficiently dry, the cement paste was applied to the surface with a roller and dried, and then an acrylic resin solvent-based paint was applied to finish.

6) Even after 3 months had passed, there was no need for swelling or swelling.

Example 4 An adhesive based on acrylic vFt1 finger was added at a rate of 15% to the wall surface of the resin-treated glass fiber fabric used in Example 2 in almost the same condition as that used in Example 1. Embedded using emulsion paint.

After drying, I finished it off with two coats of emulsion paint. As a result, the cracked wall surface was beautifully finished, and the cracked area was reinforced and was able to withstand the impact of the bombs.
