A solution of silane is suitable in consolidating weathered and softened stone. It penetrates deeply into the stone and makes it regain its original cohesion. However, it is not useful for granularly decayed stone because its tackiness is too low to join the granules and it has no ability to fill up the voids between the granules. On the other hand, organic resins have much lower durability than silane, though they have high tackiness and good filling ability. Thus, the author carried out an experimental study on the mixture of silane and acrylic resins as fixer of stone granules. The mixture of silane solution (SS-101) and acrylic resin (Paraloid B-72) proved excellent for this purpose. The superior effect of mixing these products can be explained as follows: In the early stage of the volatilization of the solvent, Paraloid B-72 gives the mixture high tackiness by which stone granules are joined with one another. When most of the solvent volatilizes, the silane starts to cure. Supported by cured Paraloid B-72, the silane continues to cure gradually. Finally when the silane cures completely, it fixes the stone granules very strongly. The fixing lasts very long because of the high durability of the silane.
