Abstract
Surface of the wooden cultural heritage has been protected from moisture by natural oils (such as perilla oil and tung oil), which accelerated degradation. But we can find seldom the research on the processes and performances of oil coatings. In this study, the water resistant performances by wood direction were compared to 3 types of natural oil and 2 types of oil stain, and the effect of additional indoor conditioning and temperature of oil were appraised in longitudinal direction. The natural oils block moisture about 79.2% comparing to the control in longitudinal direction. Especially the tung oil showed the outstanding water resistance about 90.5%. The water resistant performances decreased about 8.8% by additional indoor conditioning for 2 years. Heated oil improved the water resistance about average 5.0%.(Max. 9.6% with linseed oil).
