We studied to select the best consolidant and water-repellentsynthesis resins on the weathering caused by many factors(temperature variation, ultraviolet light, moisture, salt etc.) for using internal or external of stone cultural properties. The specimen〔granite(Pochon-suk), granite(Hwangdung-suk), tuff(in Kyong-ju)〕was treated by Wacker OH, Wacker OH 100, Wacker 290L, D.W.R, SS-101and tested in the five kinds of test and analyzed. After all test, D.W.R is the excellent results on the measuring of the property of matter. Especially, water-repellent efficiency is the best.
