いものである。As is clear from Table 1 above, a modified acrylic compound having a functional group that reacts with both the stone 1 and the mortar on the surface to which the mortar is adhered, such as the back surface or the side surface of the stone 1 as in the present invention. It was found that the sample of the present invention coated with No. 2 had better stain resistance and stronger adhesive strength with mortar than the comparative sample. By the way, in the construction of the stone material 1 of the present invention as described above, in order to protect the surface of the stone material 1 (prevent stains), paper tape or masking is applied to the four sides of the surface of the stone material 1, and the paper tape or the masked stone material 1 is applied.
Is adhered by mortar, but it takes a lot of work to apply a paper tape or masking on the four sides of the surface of the stone material 1 at the time of construction, if the construction area is large,
On the surface of the stone material 1, a paint (stripping paint) that can be peeled off after hardening is applied in advance, or a peelable sheet (rimmable sheet) is attached. The peelable paint is intended to protect from external mechanical and chemical damages during storage and transportation, and to temporarily prevent rust and prevent contamination. After fulfilling the purpose, it is stripped off as a continuous free film. There are various types of peelable paints such as vinyl-based, copolymer-based resins, ethylcellulose-based paints, but it is desirable that these solvents and additives do not adversely affect the object to be coated, and polyurethane-based or acrylic-based paints are desirable. .. Then, the stone material 1 is attached with mortar, and after the joint construction between the side surfaces is completed, the paint or sheet applied to the entire surface of the stone material 1 is peeled off. This makes it possible to omit the additional king of paper tape or the like during joint construction. Further, it is useful for protecting the surface of the stone material 1 at the time of construction and preventing dirt after the construction, and also for protecting the stone material 1. By the way, when the stone material 1 of 400 mm x 400 mm size is stuck on the wall surface by about 2.4 m 2, the masking time by the paper tape at the time of joint construction needs about 1/2 of the joint construction time, and the joint on the surface of the stone 1 There are 4 to 5 parts of the agent protruding, but if a coating that can be peeled off after hardening (stripperable coating) is applied to the surface of the stone material 1 beforehand, or if a peelable sheet (removable sheet) is attached The joint construction time is about half, and there is no problem with the joint agent squeezing out from the stone 1 surface.

Therefore, it is possible to prevent contamination from the mortar side on the surface that becomes the adhesion surface of the stone material with the mortar, and, even though it was made to improve the stain resistance in this way, Since a modified acrylic compound having a functional group that reacts with both is applied,
The adhesiveness with mortar is improved.
