Abstract

PURPOSE: To form an attractive wall surface by filling a filler into nail holes produced after temporary fixing nails are removed, drying the filler, and wiping off a portion protruded to the outside to close the nail holes. CONSTITUTION: An inner wall material 1 is stuck on a bed material 3 through an adhesive agent 2, and temporary fixing nails 4 are driven into the front surface of the inner wall material 1 at proper positions. After the adhesive agent 2 has been dried and cured, the temporary fixing nails 4 are removed. A filler 6 of the same system as the inner wall material 1 is forced into the nail holes 5 formed after the nails 4 have been removed to a proper depth. After the filler 6 has been dried approximately, the filler 6 over the nail holes 5 is wiped off to terminate the closing of the nail holes 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of forming a wall surface using an inner wall material having a substrate such as a gypsum board or a calcium silicate board.

(Prior art) When forming an interior wall by attaching a plurality of interior wall materials to a base material, it is not desirable to fix these interior wall materials by direct nailing because the nail heads are exposed on the wall surface, which is undesirable in terms of appearance. Generally, a method is used in which an adhesive is applied to the back surface of each inner wall material in advance and the inner wall material is adhesively fixed to the base material.

In this case, it is necessary to fix the inner wall material so that it does not move until the adhesive dries and hardens, so as a means of fixing, drive temporary nails from the surface side to the base material, and after adhering sufficiently, pull them out. things are being done.

(Problem to be solved by the invention) However, on the surface of the interior wall material that has been covered in this way, nail holes remain after the temporary fixing nails have been removed, and these nail holes are
When the interior wall material is wood board or fiberboard, the nail holes shrink due to the elasticity of the material and are not so noticeable, but in ceramic products such as plasterboard, these nail holes are quite noticeable and spoil the aesthetics. To remove a peg, the hard synthetic resin part that is the nail head is held in place with a tool and pulled, but it is difficult to match the pulling direction with the direction in which the nail was driven; This results in a hole that widens towards the mouth, and there is no restorability.In addition, in brittle materials such as gypsum boards, the nail holes expand more rapidly, and gypsum boards are considerably heavy. Therefore, when driving temporary nails, there is a risk that the inner wall material will move to one side and the nail hole will become wider.

However, filling the nail hole with adhesive caulking material to close the nail hole on a stretched wall surface will warp and destroy the nail hole edge and enlarge it, and it is not recommended to use oil-based materials. Because of the risk of smearing on the decorative surface, it was generally considered that there was no other option but to leave the numerous remaining nail holes as they were.

(Means for Solving the Problem) On the other hand, the present invention provides a solution that is similar to the gypsum board or calcium silicate board that is the substrate of this inner wall material, especially for the nail hole after removing the temporary nail. A filling material made by softening fine-particle powder with water.

Apply the filling material into the hole to an appropriate depth while applying pressure that is not likely to destroy the edge of the nail hole, and after the filler is almost dry, slightly wet the protruding part on the outside. These nail holes can be closed by wiping with a damp cloth or dry cloth.

(Embodiments of the Invention) The order of implementing the method of this invention will be explained with reference to the drawings.

(1) Using a gypsum board, calcium silicate board, etc. as a substrate,
The inner wall material 1, which has a synthetic resin layer or wallpaper layer on one side and has a finely uneven decorative surface, is attached to the base material 3 via the adhesive 2, and temporarily fixed to the appropriate place on the surface of the inner wall material 1. Drive in each nail 4 (Figure 1) (2) After the adhesive 2 dries and hardens, remove the temporary nails 4. (Figure 2) (3) Nail hole 5 formed by removing the temporary fixing nail...
Separately, water is added to a powder material of the same family as the substrate, that is, a material of the same family as gypsum (lime sulfate), calcium silicate, etc., such as limestone powder, with an appropriate binder powder added. After piling up the softened filler 6, gently push it into the nail hole 5 to an appropriate depth with your fingertips or a spatula (Fig. 3). (4) When the filler 6 is almost dry. In this state,
Wipe off the filler 6 on the nail hole 5 by wiping from the side to one side with a cloth. (FIG. 4) In this way, each nail hole 5 is closed: and since these closed portions are scattered on the uneven decorative surface of the inner wall material, they are hardly noticeable in appearance.

In addition, the above-mentioned filling material 6 is prepared in advance. A color similar to the uneven decorative surface. Needless to say, it can be used.

(Effects of the Invention) The present invention has the above configuration, and the filler 6 coated into the nail hole 5 to an appropriate depth is made by softening a powder of the same type as the substrate of the inner wall material 1 with water. Because of this, it has good adhesive properties, and at the same time as it is applied, the moisture seeps into the material structure of the substrate exposed on the inner peripheral surface of the nail hole 5, and becomes integrated with the material of the filler 6. join to.

In this case, the water in the rod-shaped part of the nail hole 5 rapidly moves outward, resulting in a hard kneaded state with a slightly coarse density, but the degree of shrinkage is low, so filling performance is good, and the rod-shaped part of the nail hole 5 The part that protrudes outward from the rim of the mouth dries in a soft state and shrinks slightly, but a dense sticky part is formed, and even when this part is wiped with a cloth, the part will come off all at once. There is no fear.

As described above, according to the present invention, it is possible to create a beautiful wall surface in which each nail hole is closed when covering an interior wall material using a gypsum board, a calcium silicate board, etc. as a substrate, and It has many advantages, such as the fact that it is extremely easy to close the holes.

[Brief explanation of the drawing]

The drawings are explanatory cross-sectional views showing the order in which the method of the present invention is carried out, and FIG.
The figure shows the same removed state, FIG. 3 shows the state with filler applied, and FIG. 4 shows the state with excess filler wiped off. In the figure, 1 is an inner wall material, 2 is an adhesive, 3 is a base material, 5 is a nail hole, and 6 is a filler.

Claims (1)

[Scope of Claims] An inner wall material with a finely uneven decorative surface formed by providing a layer of synthetic resin, paper, etc. on a substrate such as a gypsum board or a calcium silicate board is attached to a base material via an adhesive, and In the case where temporary fixing nails are driven into the surface and held and fixed, and then the temporary fixing nails are removed after the adhesive has hardened, each nail hole after these removal is filled with a filler made by softening a powdered material of the same type as the substrate with water. A wall surface forming method characterized by applying paint and wiping off the protruding parts on the outside after it has almost dried.
