Waterproof materials are widely used in conservation for stone and earth cultural relics. This paper attempted to introduce some popular waterproof materials in the conservation for wooden wares. After the treatment, the properties of samples were tested on the changes of color, contact angle, water absorption by capillary, water absorption in submerged environment, mildew - growing text and the influence for next treatment. The experiment indicated that the waterproof materials applied had some effects, especially the WD -10 with high consistency. The wood wares still grew mildew in moist environment for a long time, so it was necessary to apply some antiseptics and anti-mildew agents or other conservation materials together. The waterproof materials will not affect the next treatment.
