Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for removing a fibrous topcoat wall, and its purpose is to provide a method for smoothly repainting a right wall finished with a fibrous topcoat material. It is in.

To remove the traditional seed-right wall, use a brush or hand broom to soak water into the wall, and then trowel the wet wall.

They used to scrape it off with a spatula, but due to the absorption of water by the wall base and drying of the surface, it took a lot of effort to evenly moisten the top layer of the wall, and when it was removed, the areas that dried quickly became dusty. Topcoat 11, which uses a synthetic resin emulsion as an adhesive, does not easily soften when wet with water, and if it is forcibly removed, it may damage the wall base. However, many problems remained, including the fact that repairs were extremely troublesome.

Original F! In view of these circumstances, as a result of extensive testing and research, A:b etc. were applied by applying an aqueous solution containing 1 water-soluble glycol ether and a water-soluble glue to the wall surface finished with a fibrous top coat material. By scraping off the wall coating layer moistened by the paint, it was surprisingly discovered that the scales could be peeled off extremely smoothly from the right wall without damaging the wall base.

The reason why the method of the present invention gives favorable results is as follows.
Water-soluble glycol ether and water-soluble glue are added to the water to give the treatment liquid appropriate lipophilicity and viscosity, increasing the adhesion of the treated water to the wall surface and the solubility of the synthetic resin adhesive contained in the right wall. This is thought to be due to the fact that it suppresses the penetration of treated water into the wall base and its surface drying, allowing the treated water to be evenly impregnated into the wall coating layer. The common ones are ethylene glycol monomethyl ether, ethylene glycol dimethyl ether, diethylene glycol monoether ether, triethylene glycol monoethyl ether, ethylene glycol motsubutyl ether, diethylene glycol motsubutyl ether, etc., and the amount used is based on the constituent components of the right wall. In particular, the water-soluble glycol ether and water should be blended in a weight ratio of 1:1 to 70, depending on the type of adhesive.

The water-soluble thickening agent used in the method of the present invention is carboxymethyl cellulose, methyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxyethyl cellulose, polyacrylate, etc. It is blended in a range of 1 to 10% by weight.

In carrying out the present invention, ethylene glycol is added at a ratio of 2 to 10% to a treatment solution containing water, water-soluble glycol ether, and water-soluble glue to prevent freezing in the winter and rapid drying in the summer. Furthermore, an anionic or nonionic activator can be added in a proportion of 0.01 to 5% to increase the permeability of the treatment liquid into the wall coating layer.

In the method of the present invention, the treatment liquid can be applied to the wall surface finished with Hl or fibrous topcoat using a trowel, brush, roller, spray gun, etc. After leaving it for 5 to 60 minutes, scrape it off with a trowel, knife, cutter, spatula, etc.
It is possible to remove the top coat and create a base for repainting.

This will be specifically explained below using examples.

The numerical units are shown in Chongchu.

Example 1 50 parts of ethylene glycol monoethyl ether, 1 part of carboxymethyl cellulose, 2 parts of methyl cellulose, and 3 parts of ethylene glycol were mixed and dissolved in 250 parts of water,
The above treatment solution was applied with a brush at a rate of 17F/approximately 400F to the right wall, which had been troweled with a wall material made of wood flour as the main material and carboxylic methyl cellulose as a glue, on the wall base consisting of an intermediate coating. If you leave it for 20-20 minutes and then scrape off the wall surface with a trowel, you can remove the topcoat wall very easily without damaging the wall base, and then trowel the topcoat wall directly on the bottom surface. was completed.

Example 2 50 g of ethylene glycol motubutyl ether, 3 parts of sodium polyacrylate, and anionic activator "Desol mp"
Mix and dissolve 5 parts of JO (manufactured by Kako Atlas) in 250 parts of water, apply acrylic resin emulsion and carboxymethyl cellulose as adhesive to a wall material made of colored sand on a wall base made of gypsum plaster, and dry. The treatment solution was applied to the treated wall using a trowel at a rate of about 500 f/d, and after being left on the SO for 20 to 20 minutes, the wall surface was scraped off with a trowel. It was possible to remove the topcoating machine and apply the topcoat wall directly to the surface.
