The mixture of silane and organic resin was evaluated in the laboratory as consolidant of granularly decayed stone. The evaluation was done by testing how strongly the mixture fixed stone granules on a substrate stone piece. As a result, the mixture of silane solution (SS-101) and acrylic resin (Paraloid B-72) proved to be highly superior. The role of the acrylic resin Paraloid B-72, when mixed with the silane solution SS-101, is to increase the viscosity of the mixture properly so that the mixture not only penetrates but also remains sufficiently in the voids among the stone granules and the stone substrate, and to give the mixture gluing ability in the early stage which the silane by itself lacks. The high durability of the mixture after curing depends on the excellent durability of the silane. -- AATA
