る。Conventionally, when applying mortar coating to a building, the lath base material is usually applied between the pillars of the building, then waterproof paper is pasted on the surface, and then metal is applied on top of that. A lath net is stretched and then mortar is applied onto the lath net.

る施工法を採用しているのが実情である。However, this construction method not only requires a lot of manpower and time, but also causes the applied mortar layer to lift up from the base material. There is a strong demand for such a mortar base material to which a mortar layer can be attached.Of course, it is necessary to develop a base material that can be coated with mortar directly on the surface of rough-hewn wood, which is commonly used. Although various attempts have been made, the problem that peel strength decreases as drying accelerates after applying mortar remains unresolved, and the above-mentioned waterproof paper and system still cannot be used when applying mortar to buildings such as houses. The actual situation is that a construction method using netting is used.

’ｋ ’ｌｙ％供するものである。In order to solve the above-mentioned problems, the present invention has conducted various studies on the adhesion with mortar, and as a result, it was found that the mortar coating surface of the base moon is a rough color, and the cement component is severely eroding the adhesion with mortar. Based on the knowledge of be.

て構成してなるものである。The following is a concrete explanation based on the drawings showing the embodiments of the present invention. An adhesive (21'i) is applied to the surface of the base material (1) to form granules with an apparent diameter of about 0.5 to 2u. The surface of the base material (1) is made up of granular cement (3) by scattering cement (3) in a line to such an extent that the surface of the base material (1) cannot be seen.

知の防水剤を塗布することが一層好ましい。As the base material (1), a wood board such as scraping equipment, plywood, or a board made of wood chips is used, and as the adhesive (2), an emulsion type material with excellent adhesion to both wood materials and cement components is used. IE:a is mainly composed of acrylic resin, and adhesive (2) is applied to the entire surface of base material (1) from the viewpoint of waterproofing, or other well-known waterproofing agent is applied. It is more preferable to do so.

る。Granular cement (3) is 10 parts cement to 1 part water.
．． 700-1000 while gradually feeding 5-168
．． If the cement is stirred at /I for about 3 to 6 minutes, the cement becomes granular, and it can be obtained industrially by drying the granular material and then passing it through the desired mesh. When making the above-mentioned cement agglomerates, for example, if about 10 to 301 parts of calcium carbonate are mixed in, it is possible to obtain a granular material that is lightweight, has good water absorption, and has good sawing and nailing properties. This is even more convenient as a base material of the present invention.

。The base material (1) is coated with adhesive (2), that is, an emulsion whose main component is acrylic resin, and atomized cement (3) is applied to the base material (1).
) After spraying, heat dry m (5 to 100°C for about 6 to 50 minutes).

となる。The size of the sweet grain cement (3) is determined by its apparent diameter, taking into account adhesion to the base material (1), surface roughness after adhesion, and various aspects of production such as cutting and nailing. is about 0.5
A roughness of ~2 Tsuru is suitable; if the roughness is less than 05, the adhesive strength with Kamortar, which has a relatively smooth surface roughness, will decrease, and if the roughness is larger than 2M, cutting and hammering operations will become unsmooth. Become.

。In this way, the mortar base material in the present invention has an adhesive (based on acrylic resin) on the surface of the wooden base material (1).
Since it is made by fixing the granular cement (3) with a diameter of about 0.5-2 fl through the mortar 2), the mortar coated surface (the surface of the base material) becomes a rough and rough surface.
In addition, since the rough surface is a cement component, it has a high affinity with mortar and has extremely good bonding strength (adhesion) with mortar, increasing peel strength, and can withstand changes such as wind, rain, dryness, etc. It can maintain bonding strength with mortar for a long period of time. Moreover, since the apparent diameter of the granular cement (3) is approximately 0.5 to 2 u, it can be cut, and cracks will not occur when nailed.
