Abstract

PROBLEM TO BE SOLVED: To provide a wall surface renovating method capable of rapidly renovating a wall surface under a state for making most use of the features of an old wall paper.SOLUTION: Damaged parts such as peeled portions and scratches of a wall paper stuck on a wall surface are removed, while the wall paper parts existing on unexposed parts such as decorative covers for receptacles are cut off and they are stuck on the wall parts with the wall paper removed. Then, a pigment-based paint containing a resin emulsion of 30 to 40 wt.% containing a styrene acryl resin of 10 to 20 wt.% and a pigment of 30 to 50 wt.% is sprayed onto the wall paper flattened by the sticking by airless spray to form a new wall surface.

Description

  The present invention relates to a wall surface regeneration method for reproducing, for example, a dirty or damaged wallpaper, and more particularly to a wall surface regeneration method that allows an old wall paper to be reproduced on a wall surface without being peeled off.

  Generally, when the old wallpaper is peeled off and a new wallpaper is pasted, the following method is used.

  First, when peeling off the old wallpaper and pasting the new wallpaper, the old wallpaper is peeled off using a spatula or the like, and the wall surface is flattened using a spatula or the like so as not to leave any peeling. At this time, if there is a dent or the like on the wall surface, the dent is filled with a material such as a putty or a clay agent, and then a new wallpaper is pasted.

  However, such a method has a problem that not only it takes a long time to peel off old wallpaper, but also a large amount of old wallpaper is generated as industrial waste.

  Therefore, there has been proposed a method of pasting a new wallpaper from above without removing such an old wallpaper (Patent Document 1). According to such a method, since it is not necessary to remove old wallpaper, there is an advantage that it is possible to shorten the work time for remodeling and to prevent the generation of industrial waste.

  However, the method described in Patent Document 1 also causes the following problems.

  That is, in the method described in Patent Document 1, for example, the background wallpaper is a material having a user's favorite uneven pattern, or a sound-absorbing material having micropores on the surface, or the like. In such a case, when a paste is applied from above and a new wallpaper is pasted, the uneven pattern of the base and the sound absorbing effect are lost. In addition, when applying glue on the underlying wallpaper, it is necessary to apply a normal glue paste with a roller or brush. Not only does this take place, but it also requires a new wallpaper to be pasted before the glue dries out, so the work must be quick.

  Therefore, in order to solve the above-described problems, an object of the present invention is to provide a wall surface regeneration method capable of quickly reproducing a wall surface in a state in which the characteristics of old wallpaper are utilized.

  That is, in order to solve the above-mentioned problems, the present invention regenerates damaged parts such as peeling and scratches on the wallpaper affixed to the wall surface, and flattens the surface. And a step of spraying a pigment-based coating agent having 30 to 40 weight percent as a pigment and 30 to 50 weight percent as a pigment to form a new wall surface.

  In this way, a thin coating film can be formed by spraying on the surface of the old wallpaper with the optimal component percentage of the resin emulsion and pigment, without significantly changing the pattern of the underlying wallpaper or the sound absorption performance, etc. The surface can be regenerated cleanly. Moreover, since the pigment-based coating agent can be sprayed by airless or the like, the working time can be remarkably shortened.

  In such an invention, the resin emulsion contains 10 to 20 weight percent of the resin.

  Furthermore, a styrene-acrylic resin is used as such a resin.

  In addition, in the case of flattening the wall surface, it includes a step of partially peeling the damaged portion of the wallpaper, and a step of cutting off the wallpaper of the non-exposed portion such as the decorative cover of the outlet, the lighting fixture, and pasting it on the peeled region Like that.

  According to the present invention, the step of flattening the surface by regenerating a damaged portion such as peeling or scratching of the wallpaper attached to the wall surface, and 30 to 40 weight percent as a resin emulsion on the flattened wall surface, Spraying a pigment-based coating agent having 30 to 50 percent by weight as a pigment to form a new wall surface, so that a thin coating is applied to the surface of the old wallpaper by an optimal blending percentage of the resin emulsion and the pigment. A film can be formed. As a result, the surface can be reproduced cleanly without greatly changing the uneven pattern or sound absorption performance of the underlying wallpaper. In addition, since the pigment-based coating agent can be sprayed by airless, the working time can be remarkably shortened, and the wall surface can be regenerated at low cost.

The figure which shows the wall surface reproduction | regeneration process which shows one embodiment of this invention

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The wall surface regeneration method in this embodiment utilizes the uneven pattern, texture, silencing characteristics, etc. of the existing wallpaper by spraying the wall coating agent over the existing wallpaper affixed to the wall or ceiling of the indoor space. It is designed to be finished on a clean wall surface and is carried out by the following steps.

  First, in the first step, advance preparation for applying paint to the wall surface is performed. In this advance preparation, for example, a common hallway, a passage, a material storage, etc. are cured, and materials are carried in that state. Then, the indoor doors, lighting fixtures, furniture, etc. are removed, the wall surface with the wallpaper attached is all exposed, and the area other than the regenerated portion of the wall surface is cured with a vinyl sheet or curing tape.

  In the next second step, first, oil stains and the like are removed from the wall surface to be regenerated with a sponge or the like. At this time, if there are scratches on the wallpaper, peel off the scratched or dirty part into a rectangular shape and paste the wallpaper prepared in advance on that part, or the back side of the decorative panel on the outlet Then, the wallpaper pasted on the hidden part (non-exposed area) with the lighting fixture is cut out, and the cut-out wallpaper is pasted on the area where the scratched part is peeled off. At this time, the wallpaper is pasted so that there is no gap in the cut rectangular shape. In addition, if there is a dent on the wall surface, a material such as clay is used to fill the dent and flatten the surface. In this way, if the wallpaper in the non-exposed area is peeled off and pasted on the area where the scratches are removed, the same water-repellent performance, sound absorption performance, and film thickness are used. However, the atmosphere does not differ from other parts only in that region. In addition, even when there is no wallpaper of the same material due to out of stock or the like, the wallpaper of the same material can be pasted in the area of the scratch portion.

  In the third step, after the wall surface is flattened in this way, an operation of removing oil from the wall surface is performed. In this oil removal operation, a surface treatment agent called a sealer is applied to cover the oil, etc., or water is attached to the wallpaper with a lightly dampened sponge or spray, etc. Remove oil with alcohol or alcohol.

  After performing the preliminary work in this way, in the next fourth step, the wall surface coating agent is sprayed airlessly and thinly applied. At this time, the spraying thickness is set such that the yellowing or dirt of the base can be concealed, and when the base is a sound-absorbing material, the pores are not buried. Such a thickness is impossible with a brush or a roller, but in this embodiment, the percentage is such that it can be sprayed with airless, so it is very thin and can hide dirt. .

  Here, as the wall surface coating agent used in the spraying treatment, a resin, pigment, solvent, additive, and water-containing one are used.

  The wall coating agent will be described in detail. As the resin component, an emulsion obtained by emulsifying styrene / acrylic resin in water as a binder is used. As these components, if the percentage as a resin (solid content) is large, the paint can be strongly solidified on the wall surface. However, since the viscosity increases as the component percentage increases in this way, the coating becomes thicker and the base becomes thicker. There is a possibility that the pattern and texture of the wallpaper will be lost and even the sound-absorbing porosity will be blocked. On the other hand, if the percentage is too small, the viscosity becomes weak, and the pigment may adhere to the body when the body is brought into contact with the wall surface. For this reason, it is preferably contained in the range of 10 to 20 weight percent as a percentage of the styrene / acrylic resin, and preferably in the range of 13 to 17 weight percent. The emulsion containing the styrene / acrylic resin is in the range of 30 to 40 weight percent (preferably 33 to 37 weight percent).

  As the pigment, titanium oxide is used as a color pigment for making white, and talc, calcined aluminum silicate, muscovite, aluminum hydroxide, etc. are used as extender pigments for giving the coating film thickness. Furthermore, as a pigment for finishing the wall to the desired color, yellow iron oxide is used for ocher, red iron oxide is used for red rust, carbon black is used for black, and phthalocyanine blue is used for blue. When red or yellow, organic red / yellow pigments are used. As the component percentage of these pigments, since the wall surface is generally white, the titanium oxide is 10 to 20 weight percent, the extender pigment is 10 to 15 weight percent, and the calcined aluminum silicate is 1 to 3 weight percent. Percentage, 1 to 3 weight percent of muscovite, 0.5 to 1.5 weight percent of aluminum hydroxide, and 0 to 5 weight percent of yellow iron oxide and red iron oxide. Carbon black, phthalocyanine blue, and organic red / yellow pigments are set to 0 to 2 weight percent, but these component percentages can be changed according to the user's preference.

  As the solvent, di-n-butyl phthalate for imparting flexibility to the coating film, ethylene glycol or the like as a material for enabling the paint to be stored at a low temperature is used. These solvents are about 0.2 to 1.5 weight percent with respect to the whole.

  Additives include pigment dispersants that uniformly disperse pigments to stabilize the dispersion state of pigments in paints, viscosity imparting agents that make paints easy to apply and prevent dripping, and organics for preservatives. Antibacterial / antifungal agents and antifoaming agents for reducing foam in the paint are used. These component percentages include 0.5 to 1.5 weight percent pigment dispersant, 0.1 to 0.5 weight percent as a viscosity imparting agent, and 0.1 to 0.00 weight as an organic antifungal agent. About 3 weight percent and about 0.1 weight percent are added as an antifoaming agent.

  In addition, 40 to 50% by weight of water as a base of the water-based paint is contained as another component, and after spraying in an airless manner, the moisture is evaporated to form a coating film on the wall surface.

  Then, in the next fifth step, the wall surface coating agent applied to the wall surface in this way is allowed to stand for about 30 minutes to 120 minutes to be naturally dried. In this drying process, since no organic solvent such as benzene is used, no harmful substances are generated and no health hazards are caused.

  In the final sixth step, post-processing is performed. In this post-treatment, the curing is removed and the lighting fixtures, indoor doors and furniture are restored. Also, the airless is cleaned and the cleaning liquid is stored in a bucket or the like. About the washing | cleaning liquid stored in this bucket, a powder flocculant is added and stirred, and it solidifies, and isolate | separates into a water | moisture content and a solid substance through a filter. The separated water is then treated by flowing it into drainage so that the solid matter can be disposed of as industrial waste.

  As described above, in the present embodiment, the step of flattening the surface by regenerating damaged parts such as peeling or scratches of the wallpaper attached to the wall surface, and 10% of styrene / acrylic resin on the flattened wall surface. And a step of spraying a pigment-based coating agent having 30 to 40 weight percent of a resin emulsion containing 20 to 20 weight percent and 30 to 50 weight percent as a pigment to form a new wall surface. The percentage allows a thin film to be formed on the surface of the old wallpaper. As a result, the surface can be reproduced cleanly without greatly changing the uneven pattern or sound absorption performance of the underlying wallpaper. Moreover, since the pigment-based coating agent can be sprayed in an airless manner, the working time can be significantly shortened compared with the case of applying with a brush or a roller, and the work can be performed at low cost. Become. In addition, this paint only adheres to the surface of the wallpaper and does not penetrate inside, so it does not damage the gypsum board on the inside, and the surface is coated with resin, preventing scratches and dirt. Prevention, fire prevention performance, etc. can be provided.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used in industrial fields such as renovation for reproducing wallpaper already pasted in an indoor space.
