In this case, an aqueous coating agent is used. Then, moisture may penetrate into the base material of the wooden floor and cause problems such as warpage, deformation, and cracking. Therefore, a method of exclusively applying an oil-based urethane resin coating agent has been used. However, the coating film of the coating agent has a reduced gloss due to wear due to use, adhesion of heel marks due to shoe soles, etc., or penetration of wear and dirt into the coating film due to the incorporation of earth and sand, resulting in an aesthetic appearance with time. Because of the deterioration, it was necessary to periodically remove the dirt and restore the initial appearance. Therefore, in order to repaint the flooring-finished floor surface, (1) a method of completely shaving off the paint film with a sander or a mesh and applying a new oil-based urethane resin coating agent;
(2) A top coat method in which an old paint film is roughened with a mesh of about 100 and a new paint film is applied.
(3) A method of applying an oil-based urethane-based resin coating agent directly to a flooring-finished floor and then applying a water-based resin finishing agent other than urethane-based resin has been performed.

Although it depends on the frequency of the replacement, it is necessary to replace the flooring in about 18 years in the case of replacement every 6 years. In addition, when shaving with a sander or mesh, a large amount of dust is generated, the working environment is very poor, causing problems due to scattering to incidental facilities, and the next application until the scattering of the dust into the air stops. There was a problem that the workability was very poor that the user could not move to work. There was also a problem that the collected dust had to be discarded as industrial waste.

再塗装方法を提供するものではなかった。In the top coat method (2), a new paint film (top coat) is placed on an old paint film (base).
When repainting, to improve the adhesion between the old paint film and the new paint film, scrape the old paint film with a mesh,
An operation for roughening the surface is required, which causes a problem of dust generation similar to the method (1). Also,
As a result of shaving the old painted surface using a polisher equipped with a mesh, there was a problem that fine scratches on the painted surface, which are referred to as mesh marks, did not disappear even after overpainting a new painted film. Also, in order to keep the adhesion as good as possible, the top coat should be a two-part curable paint if a two-part curable paint is used for the base, and the top coat if the base is a one-part curable paint. It is common to use a one-component curing type paint, but in many cases, there is often no history of whether the base material was a two-component curing type or a one-component curing type. there were. Further, in the case of the methods (1) and (2), oily urethane-based paint is generally used as a newly applied paint, which contains a large amount of an organic solvent, thereby increasing worker's health. There was a problem that had an adverse effect. Also, in order to avoid adverse effects on the health of workers, the method (3) using a water-based resin finish other than the urethane type has been conventionally performed. However, in general, scuffs (small scratches) and heel marks (shoes) have been used. Inferior durability to oil-based paint, etc.
Further, since the thickness of the film is small, there is a problem that the durability of the coating film due to abrasion is short. As described above, any of the conventional methods has many problems and does not provide an effective repainting method for maintaining the aesthetic appearance of the wooden floor.

The present inventors have conducted intensive studies and found that instead of scraping the coating film with a sander or a mesh on a floor where a urethane resin coating agent is applied on a wooden floor, a urethane resin coating agent on the floor surface is used. After cleaning with a specific cleaning method, and then applying a water-based urethane resin coating agent instead of an oil-based urethane resin coating agent, it is extremely difficult to cope with the underlying coating film, which was difficult with conventional oil-based coating agents. The present invention has been found to provide good adhesion, solve problems such as dust generation, poor adhesion, and poor working environment, and provide a floor surface gloss that is superior to the aqueous resin finish method in terms of durability. Reached. That is, the present invention relates to a method for repainting a surface of a wooden floor applied by using a urethane resin coating agent, wherein the surface of the urethane resin coating agent applied to the wooden floor is washed with water. , Followed by finishing with an aqueous urethane resin coating agent. The wooden floor referred to in the present invention includes a flooring made of a natural wood muku and a flooring made by bonding a decorative veneer of natural wood to any base material, and also described below. Flooring-finished floor refers to a floor that is finished using a floor material manufactured by bonding a decorative veneer of natural wood to the surface of a base material such as plywood. In the present invention,
The target is a floor in which a urethane-based resin coating agent is applied in advance on a wooden floor, but if the urethane-based resin coating agent is not applied, an oil-based urethane resin coating agent is applied and the wood-based floor is applied. Must be sealed in advance. In general, oil-modified urethane resin coating agents include oil-modified one-pack type and moisture-cured one-pack type and two-pack reaction type. On the other hand, when the aqueous resin finish is coated on the painted surface of the urethane resin coating agent, as in the method using the aqueous resin finish,
It is necessary to completely remove the aqueous resin finish by using a release agent suitable for the finish.

ことで実施できる。[0007] The present invention is characterized in that an existing coating film is washed with washing water and then finished with an aqueous urethane resin coating agent. The washing is performed by a normal washing method using washing water. Used. In this case, it is preferable to use, as the washing water, washing water which has high washing properties and does not cause yellowing of the painted surface or leave no washing components. As a washing method, preferably, a polisher equipped with a pad or an automatic floor washer, particularly a method using a red pad or a blue pad as a pad and attached to a polisher or an automatic floor washer is suitable. In addition, when an automatic floor washer is used, the residence time of the washing water on the floor surface is shortened, and the workability is improved, which is a preferable method. Such a cleaning method can be implemented by cleaning the surface of the existing painted surface and polishing it appropriately.

かい傷を除去するものまですべてを包含する。In the cleaning, instead of scraping off the existing coating film with a sander or a mesh as in the conventional method, the cleaning is performed to the extent that a part or all of the existing coating film can be confirmed with the naked eye. Is enough. This cleaning solves the problem that fine scratches on the painted surface, which are referred to as mesh marks, do not disappear and remain noticeable even after a new coating film is applied. Conventionally, if a part of the existing coating film remains, if it is subsequently re-painted with a finishing agent, there is a problem that poor adhesion occurs at the remaining portion, lowering the overall value. For this reason, in order to completely remove and remove the existing coating film so as not to remain, unnecessary work and, in some cases, even a flooring substrate were required, and the work required careful management. On the other hand, the method according to the present invention only needs to be cleaned so that the existing coating film remains, and the degree of cleaning is such as to remove physical stains that leave the entire existing coating film. Includes everything to remove wounds.

Buffing with a buffing machine is particularly preferable because fine scratches on the painted surface can be removed and gloss can be restored, and the initial high aesthetics can be restored and maintained. After cleaning the floor surface, it is then repainted with an aqueous urethane resin coating. As the aqueous urethane-based resin coating agent to be used, an aqueous one-pack type polyurethane is preferable, and an air-dry type or an oxidation-curable polyurethane is particularly preferable. The amount of the aqueous coating agent applied at one time is 30 to 15
0 g / m 2, preferably from 50 to 120 / m 2.
It is preferable to apply using a short hair mouton mop or an applicator developed for applying a coating agent for a wooden floor. As a repainting method that is practiced daily, a method is used in which a stain such as an attached heel mark or a trace of an adhesive tape is sprayed with a washing water containing a detergent component to the spot, and the spot is wiped off with a suitable cloth or the like. Thereafter, it is preferable to perform an empty wipe using a mop or the like. The cycle of the repainting method is carried out as needed. By the recoating of the present invention, good adhesion and the problems of dust generation and poor working environment, which were problems in the past, are solved.
