Conventionally, when applying a stucco-like coating to the surface of a building or building material, the plastering method is mainly done by mixing natural stone aggregates such as silica sand or Kansui 5 sand with Portland cement and adjusting the composition to a high viscosity. However, materials using only cement as a binding material are generally focused solely on the aesthetics of the surface shape, and have no relation to the physical properties of the coating film. It was being handled.

However, as the construction industry changes due to the shorter construction period and improved functionality of buildings and the modernization of building materials, that is, as the use of concrete and cement-based building materials increases, adhesiveness, which has not been much considered until now, has changed. Waterproof,
Various problems related to advances in physical properties such as weather resistance have been highlighted, and conventional materials made only by adjusting cement are no longer able to deal with these problems.

This invention was made in order to create a construction method of matching materials that shortens and modernizes construction, and is especially suitable for very thick stucco on surfaces such as unevenness, unevenness, junk, damage, etc. of the base for painting. It is intended to form a coating film in the shape of a surface, thereby adjusting the unevenness and improving the concealment of rough substrates.
At the same time, after forming a coating film that firmly adheres to the base, it has extremely high physical properties such as waterproofness and weather resistance, and is also resistant to external injuries and vibrations and shocks of the base itself, making it a revolutionary product. It was completed using a traditional method.

That is, in forming the cement-resin finishing material layer, the present invention includes: (1) a first step of coating a synthetic resin emulsion on an arbitrary base; (2) consisting of Portland cement, synthetic resin emulsion powder, and aggregate. The second step is to apply an inorganic paint in the form of a slurry, (3) the third step is to press the top of the coating film in (2) with a trowel or roller before drying, and (4) to apply synthetic resin varnish or enamel. The fourth step is to achieve excellent workability and coating film properties by appropriately adjusting each material described below.

The synthetic resin emulsion to be applied to any substrate in the first step of the present invention includes acrylic ester, methacrylic ester, vinyl acetate, styrene, ethylene, dibutyl maleate, beoba, vinyl propionate, butadiene, acrylonitrile, and vinyl chloride. It is a general term for aqueous dispersions of thermoplastic resins such as epoxy, urethane, and thermosetting resins such as acrylic acid amine esters, but it is particularly important for the suction ability to the substrate and the adhesion performance of inorganic paint in the second step. In order to improve the emulsion particle size of the synthetic resin, set it to 0.03.
This effect cannot be obtained unless the emulsion is maintained at ~0.2 micron, and the coating amount of the emulsion is also approximately 30-50 g/m.
If it is not 2 (however, depending on the solid content), there will be a decrease in waterproofness, a decrease in adhesion, and furthermore, efflorescence will likely occur in the coating film.

The inorganic paint used in the second step is essentially composed of Portland cement, synthetic resin emulsion powder, and aggregate, and water is added to this to form a slurry that is used for painting.

Synthetic resin emulsion powder is made by drying emulsion-polymerized synthetic resin without forming a fusion-polymerized film.When mixed with water, it exhibits an effect similar to that of an aqueous dispersion, but there are various types. However, in the present invention, a powdered vinyl acetate resin emulsion having good compatibility with Portland cement is most suitable.

That is, when the present inventors prepared the paint with fine river sand using conventional methods, a stucco-like paint film was formed, but pinholes and cracks appeared everywhere, and moreover, it was difficult to see from the outside. It was not good because it was fragile to scratches and stress.

Therefore, by using relatively coarse aggregate, it is first strengthened against external scratches and stress, and furthermore, by having an appropriate particle size distribution, pinholes and cracks are reduced, and the composition is set to meet the purpose of the present invention. did.

In particular, the particle size distribution of the aggregate is such that aggregate with a diameter of approximately 0.3 to 0.8 mm, aggregate with a diameter of approximately 0.8 to 1.2 mm, and aggregate with a diameter of approximately 1.2 to 2 mm.
.. 5mm aggregate at a weight ratio of 1:0.3 to 2.
They are mixed at a ratio of 0:0.5 to 1.5.

When the above ratio is exceeded, for example, the diameter is about 0.3 to 0.8
If there is less aggregate of mm, the surface becomes rough and cracks are likely to occur, and the coating film is full of gaps, making it difficult to adhere to the surface.
It has poor waterproof properties, and if there is too much of it, in addition to the above-mentioned drawbacks, the makeup will not look sharp and will lack the luxury of makeup.

In addition, if the aggregate diameter is 1.2 to 2.5 mm, the paint film will crack everywhere, resulting in a decrease in waterproofness, making it impossible to create a luxurious design, and if there is too much aggregate, it will be difficult to install it on the wall. There is a risk that the adhesive will peel off violently, resulting in a decrease in adhesion.

Furthermore, the aggregate with a diameter of about 0.8-1.2 mm is in the particle size range between the aggregate with a diameter of 0.3-0.8 mm and the aggregate with a diameter of about 1.2-2.5 mm, and the overall particle size composition is It covers.

The aggregate in the non-liquid paint used here has been described above, but the form of the composition forming the inorganic paint is approximately 2 to 20 parts by weight of synthetic resin emulsion powder and aggregate based on 100 parts by weight of Portland cement. If the amount of the synthetic resin emulsion powder is less than about 2 parts by weight, the caking properties of the paint will decrease and desired adhesion will not be obtained; If the amount exceeds 20 parts by weight, the drying of the synthetic resin emulsion components is delayed, which tends to cause primary efflorescence to occur in the dry parts of the coating film.

If the amount of aggregate is less than about 70 parts by weight, cracks are likely to occur due to drying shrinkage of the inorganic pigment, and if it exceeds about 150 parts by weight, aggregate scattering becomes large and waterproofness and adhesion are significantly reduced.

The third step consists of pressing the top part with a trowel or roller after applying the inorganic paint in the second step and before drying, preferably within 1 to 3 hours after application. There are no particular limitations to this, but it involves moistening the surface to be pressed with water and pressing lightly, forming a small flat shape at the acute angle of the convex surface.
Since it has a so-called trapezoidal cross section, the pattern may vary slightly depending on how it is pressed.

There are no restrictions on the type of synthetic resin, and either solution or water-based resins can be used freely.In short, the inorganic paint film comes into direct contact with the atmosphere in the stages up to the third process. Therefore, it is useful to prevent efflorescence of the coating film, discoloration due to efflorescence, etc., and to further improve the aesthetic appearance of the finishing material layer of the present invention.
