A thermoplastic compound useful in filling pores and voids in wooden materials, particularly edge regions, wherein the thermoplastic compound comprises a blend of two copolyesters and optionally fillers, wherein the first copolyester has a melting point of 140&deg; C. to 260&deg; C. and a glass transition temperature of &minus;10&deg; C. to 80&deg; C., and wherein the second copolyester has a melting point of 120&deg; C. to 190&deg; C. and a glass transition temperature of &minus;70&deg; C. to 10&deg; C. Also, a method of filling pores in a wooden material comprising using a thermoplastic compound having a softening point of 140&deg; C. to 200&deg; C., an open time of 2 to 15 seconds, and a viscosity number of 30 to 150 ml/g, with the thermoplastic compound preferably being a blend of two different copolyesters, wherein the application of such thermoplastic compounds enable the surfaces of chipboard panels and the like to be smoothed in a continuous one-pass process. In particular, immediate aftertreatment such as milling is possible through the use of the thermoplastic compounds.
