  The problem to be solved is a surface that improves the original moisture conditioning and prevention of condensation and imparts design properties to a plaster coating material containing a lime component of 40% by weight or more and a synthetic resin component of 10% by weight or less. Provide finishing methods.

The invention of claim 1 contains, as a base, 40 to 80% by weight of slaked lime or calcium carbonate or a total amount of both components, 25 to 40% by weight of filler, 5 to 10% by weight of pigment, and synthetic resin. 10% to 150% by weight of aggregate with a particle size of 0.1 to 1.5mm , avoiding cracks in the coating film, and the gloss of the coating film to a plaster coating material characterized by 10% by weight or less of emulsion as a resin component After blending and coating to make it low, the aggregate is formed by scratching the aggregate with a plastic mallet or wooden mallet, and when the surface loses luster and dries, it is flat with a metal bowl This is a surface finishing method characterized by rubbing to make the surface glossy, and the anti-condensation function is enhanced by increasing the surface area, and even if condensation occurs, the flow of condensation cannot be determined. In addition, it is a design that gives a polished glossy appearance and contrast, and can be adapted to contemporary designs.
The invention of claim 2 applies a plaster-tone coating material containing 40% or more of a lime component having a gloss or color different from that of the finish after the surface finish of claim 1 and having a synthetic resin component of 10% or less. In addition, the surface finishing method is characterized by producing a rubbed gloss, and the design can be produced with the streak formed in claim 2 in the contrast of color tone.

  The present invention increases the humidity control and dew condensation prevention functions of the plaster coating material and can produce a design.

  In the present invention, an aggregate is mixed with a plaster-like coating material, and after applying the aggregate, the aggregate is formed by rolling the aggregate with a plastic basket or a wooden mallet. It is in a state close to polishing, and in addition to the above stucco-like coating material as a whole, it is glossy or it is a method of contrasting the streak obtained in the previous process by applying a different-tone stucco-tone coating material in detail below explain.

  The stucco-like coating material containing 40% or more of the lime component and 10% or less of the synthetic resin component is the first element that becomes 40% or more of the total amount of either slaked lime or calcium carbonate or both components and becomes a stucco-tone coating material. . Synthetic resin is blended for the purpose of compensating for the water resistance and drying properties of the plaster coating material for synthetic resin components of 10% or less, but the blending does not lose the water vapor permeability of the coating film or the moisture absorption / release properties of the coating material itself. Means a blend.

  The moisture absorption and desorption of the wall may depend on the plaster-like coating material, and the material with high moisture absorption / release properties may be used for the base, and the plaster-tone coating material may not impair the water vapor permeability. The present invention is a method corresponding to both, and is useful in both design and effects.

The plaster coating material contains either slaked lime or calcium carbonate or both components in a total amount of 40 to 80% by weight, and the filler is calcium carbonate powder, marble powder, silica sand powder, etc. 5% to 10% by weight as a colorant, 5% to 10% by weight as a pigment, 2-5% by weight as a thickener, dispersant, antifoaming agent, etc. What is 10% by weight or less is blended in order to improve application workability for obtaining design properties, water resistance, and crack resistance.
Commercially available products are Jolipat Italian II-JP-70, JP-65, JM-65 (Aika Industry Co., Ltd., trade name) Fiorentino (Fukuko Co., Ltd., trade name), Venetian (Everfast Co., Ltd., trade name) ) Etc.

  The aggregate used in the present invention is preferably within 0.1 to 1.5 mm. Within this range, the depth of the streak can provide a thick pattern and effect, the coating film is too thick, and the coating film will not crack. The aggregate and the coating thickness are appropriately selected depending on the aggregate to be used. When the particle size of the aggregate is small, it is necessary to reduce the coating thickness. Most preferred is 2 liters of cold water stone. Although the amount of addition varies depending on the amount of streak, it is 10 to 150% by weight based on the plaster coating material, and the coating film has low gloss.

  The plastic casket or wooden casket used in the present invention is only required to have the above-mentioned aggregate caught on the casket to form a streak. Moreover, what is not wrinkles, such as blocks, such as a polystyrene foam, can be substituted.

  Apply sealer to the base as necessary.

The above-mentioned plaster-like coating material is blended with an aggregate and smoothed with a metal jar such as a 0.5 to 2.5 kg / m ² stainless steel jar.

  After the above processing, the scissors are moved in the direction of placing the streaks with a plastic scissors or wooden crates. The point is to roll the aggregate between the aggregate and the heel. At this time, since the unevenness of the ground is affected, if you want to avoid this, adjust the ground.

  Then, when the surface is about to dry, rub it with a metal scissors. More specifically, rub at the edge of the heel and hold it smoothly. The time when the surface dries can be determined by the loss of gloss of the coating film from the wet gloss immediately after application.

Apply 0.1 to 0.5 kg / m ² of a stucco-like coating material with a gloss or color different from that of the finish, apply it thinly, and then rub it with a metal scissors in a semi-dry state that is not sticky to the hand. . The difference in gloss is different from the natural finish because, as long as the plaster coating material is not low gloss, the above-mentioned finish mixes the aggregate and the gloss is lowered. Further, by changing the color, a change in gloss and a change in color tone occur due to the unevenness of the finish.

In the above process, the effect varies depending on which process is stopped. First, the scratched pattern formed on the coating film has a large surface area, and moisture absorption and desorption can be obtained. Depending on the underlying material, cracks may occur after drying. Secondly, there is no such fear when the surface is rubbed with a metal bowl when the surface is about to dry. Thirdly, when the process is performed up to the last process, the design is most effective.
These can be adapted to the user's preference as appropriate, such as design and moisture absorption / release properties.
Hereinafter, it demonstrates in detail with an Example and a comparative example. The room temperature was 25 ° C. and relative humidity 65%.
