The article deals with the effect of wood surface coating types (nitro-cellulose lacquer, polyurethane lacquer, acid varnish and water-based clear varnish) and the number of coatings on dimensional stability of beech wood. Wood surface coatings applied for wood finishing have highly different abilities to lower wood response. Their effect depends on the type of a binding agent, film density and its thickness. Diffusivity of wood surface coating films is an important parameter when choosing the best coating system for a product as to its application. Dimensional response of beech wood to climatic changes was the lowest with acid varnish finishing and the highest with the samples finished with water-based clear varnish. Half adjusting time, MEE, ASE were used as criterion indicators
