To prevent staining and efflorescence thought to be caused by the migration of water containing staining agents and soluble salts in stone, it was considered that the migration of the water in the stone must be controlled. It was believed that this could be achieved by treating stone surfaces with a barrier penetrant which has water repellency. Experiments testing five parameters were carried out. Although the scope of this research covered short term observation of the effect of barrier penetrant treatment and long term stain prevention was not confirmed, on granite the silicone type acrylic derivative polymer barrier penetrant and the alkyl-alkoxy silane type barrier penetrant were seen to prevent changes in appearance and to prevent efflores- cence. Staining and efflorescence of stone for buildings occurs frequently and a solution to these is urgent for stone work quality assurance. Knowledge obtained in this research is essential information.
