Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for forming brick or tile-like joints on walls, etc., in which bricks or tiles are formed on thick and flexible sheet materials made of paper, synthetic resins, or foams thereof. Paste a die-cut material with a joint pattern such as the following, and then trowel or spray a hydraulic coating material such as cement, mortar, or plaster, or an air-curable coating material composition such as lime or dolomite plaster. After construction, after the coating material has developed an appropriate strength, water or a synthetic resin emulsion is applied in an appropriate manner to remove the punched material from the wall surface, and after water has soaked into the coating material, By peeling off the punching mold material, the peelability between the punching mold and the cured coating material is improved, eliminating chipping of the coating material, and making it easier to form joint patterns on bricks, tiles, etc. after peeling off the punching mold material. This is about how to make it appear reliably.

The method of the present invention is used as a decorative finishing method for walls, floors, etc. by laying bricks, tiling, etc. on a flexible sheet material such as synthetic resin foam with a thickness of about 0.5 to 5.0 wn and having an appropriate strength. In addition, a molded material made by punching out a joint pattern with an appropriate design is pasted on a wall, floor, etc., and a layer of cement, gypsum, lime, dolomite silaster, etc. is applied over the molded material to the same thickness as the molded material. After troweling or spraying a coating material made of an inorganic material composition, the molding material is peeled off to form a joint pattern with an appropriate pattern on a wall or floor for brickwork, tiling, etc. There is a close relationship between the strength after construction on walls, floors, etc. and the optimal time to prevent the mold material from peeling off.For example, when the paint material is still soft immediately after construction, the peelability between the mold material and the paint material is poor; In addition, the area around the top surface of the molding material and the portions forming corners of bricks, tiles, etc. after peeling are likely to be chipped, and the surface of the coating material is likely to be damaged during the peeling process.

Therefore, it is safer to peel off the mold material after the coating material has developed a certain degree of strength.

For compositions using Portland cement as a hydraulic substance, the curing time varies depending on the temperature and humidity at the time of construction, but is usually 20°C.
It has been found that the coating material is least likely to be damaged when the mold material is peeled off after 5 to 6 hours, preferably after 12 hours.

However, the actual construction usually takes place the next day or later.
Furthermore, there is a possibility that work cannot be done the next day due to rain or other reasons. If the coating material is left for a long time after being applied, the pattern material may be damaged during the work of removing the material and may not be able to be removed from the coating material, or if the material is removed by force, some corners of the material that correspond to bricks or tiles may be damaged. may be missing.

Of course, assuming such a case, it is important to select the material of the molding material, and for this reason, 2 to 3 times expanded polystyrene resin or the like is optimal.

Against this background, we investigated a possible method that would allow the mold material to be easily removed even after a considerable period of time had passed after the paint material was applied, and also eliminate the missing parts of the paint material. By applying the resin emulsion to the surface of the coating material at a rate of 50 to 300 t/m2 using an appropriate method, the coating material absorbs moisture and temporarily softens, making it easy to apply even after the coating material has developed considerable strength. Moreover, it was found that the mold material could be peeled off without damaging the coating material.

This water dampening can not only prevent the drying out of hydraulic substances, but also act as a sealer to even out the water level on the surface of the coating material when a synthetic resin emulsion is used. This is effective in saving the amount of top coat applied and preventing color unevenness due to uneven suction on the surface of the coating material when the top coat is transparent and is a rear lacquer.

Example: ALC plate (foamed foam concrete board) whose surface was smoothed with Portland cement mortar was made with a thickness of 2.
Paste the punched shapes onto a double-foamed polyethylene sheet, leaving the brickwork joints, and apply Portland cement-based colored mortar over the entire surface to almost the thickness of the shapes (applied amount: 5 kg/m2'). Adjusted smooth with a trowel.

After the colored mortar was applied, a solution of 0.5 parts of clean water added to 1 part of an emulsion of 40% acrylic synthetic resin solids dispersed in water was added using a roller for 1502 hours.
/m2 was applied to the surface of the mortar. The acrylic emulsion applied to the colored mortar soaked into the mortar and did not stick to the hand even when lightly touched with a finger.

Foaming at this point? When the polyethylene punched mold material was peeled off, the mold material and the hardened mortar layer had good releasability, and moreover, a mortar layer with a brickwork appearance could be easily formed on the ALC plate without missing some corners or the like.
