The invention discloses a wood surface varnishing technology. The wood surface varnishing technology comprises the following steps of: firstly scraping dust, oil stains, spots, glue marks and the likeon the wood surface by using a scraping knife, clearing burrs on the wood surface, and polishing the wood surface along wood grains by using above-No.1 abrasive paper till the wood surface is smooth;mixing and stirring big white powder, rosin water, boiled tung oil and the like to form color oil meal, dipping cotton staple in the oil meal, repeatedly applying the oil meal to the wood surface, and polishing the wood surface along the wood grains by using No.1 abrasive paper after the oil meal is dried completely; preparing putty by using gypsum powder, the boiled tung oil, water and the like,then adding pigment to form oil color putty, and polishing the wood surface along the wood grains by using the No.1 abrasive paper after the oil color putty is dried completely; mixing lead oil / or ready mixed paint, gasoline, gloss oil, clean oil and the like, sieving with a bamboo basket with a square bottom and a round mouth, and brushing along the wood grains; and varnishing three times undernormal conditions, wherein the varnishing method is the same as the method of brushing the oil color. Varnish can be more evenly brushed on the wood surface according to the wood surface varnishing technology; and the wood surface varnishing technology avoids the conditions that the varnish falls off, and the varnish brushing is uneven.
