  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 is a mortar-like coating material containing 40 to 80% by weight as a lime component, either slaked lime or calcium carbonate, wherein the synthetic resin emulsion is 10% by weight or less as a resin component, and a filler. Was mixed with a plaster-like coating material containing 25 to 40% by weight of pigment and 5 to 10% by weight of pigment, and an aggregate having a particle size of 0.1 to 1.5 mm was applied to the base and smoothed with a metal jar. The surface finish is characterized by striking the surface of the post-coating film with a brush to form a pattern by raising the coating film , pressing the raised part with a metal rivet, and rubbing with a metal hoe when the surface is about to dry In addition to increasing the surface area of the humidity control and dew condensation prevention functions of the plaster coating material, the flow of dew condensation cannot be determined even if dew condensation occurs. 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 is a plaster coating material containing 40% by weight 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% by weight or less. It is a surface finishing method characterized by applying and rubbing gloss, and can produce a design with the unevenness formed in claim 1 with gloss or 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 blended into a plaster-like coating material and applied, followed by tapping with a brush to raise the coating material, press down the raised coating material, give a partial gloss, and further to the plaster The method will be described in detail below with a method of contrasting the streak obtained in the pre-coating process with a stucco-tone coating material that is glossy or different in color from the coating material.

Lime component contained 40 wt% or more, the synthetic resin component is plaster regulating coating material is 10 wt% or less first as a plaster regulating coating material comprises 40 wt% or more as the total amount of either or both components slaked lime or calcium carbonate Is an element. Synthetic resin is blended with a synthetic resin component of 10% by weight or less for the purpose of compensating for the water resistance and drying deficiencies of the plaster coating material, but the blend loses the water vapor permeability of the coating film and the moisture absorption and desorption of the coating material itself. Means no formulation.

  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, thick patterns and effects can be obtained, and the coating film is not too thick to crack the coating film. The aggregate and the coating thickness are appropriately selected depending on the aggregate to be used. Most preferred is 2 liters of cold water stone. The addition amount is 10 to 150% by weight with respect to the plaster coating material, and the coating film has low gloss.

  Apply sealer to the base as necessary.

A mixture of the above-mentioned plaster-like coating material with an aggregate is smoothed with a metal jar such as an application amount of 0.5 to 3.5 kg / m ² stainless steel jar.

  Immediately after the above treatment, the surface of the coating film is hit at the corner of the brush as shown in FIG. 1 to raise the coating film. This processing is performed according to the entire surface, local area, or random preference. In this case, the brush is preferably a so-called plastering brush. The number of brush rows is appropriately selected according to preference. Moreover, you may use the brush for exclusive use of this invention which makes a brush shape square shape and has several rows.

  After that, press the raised part that was struck with a brush and rub it with a metal scissors when the surface is about to dry. 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 surface of a film that has been struck by a coating film to form a pattern has a large surface area, while moisture absorption and desorption can be obtained. On the other hand, there is a possibility that fine cracks may occur in the raised part, and the raised part is weak against external stress. Secondly, there is a feature that fine cracks do not occur when the surface is rubbed with a metal scissors when the surface is about to dry, and even if condensation occurs. 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.
