Abstract

The invention relates to a wooden floor, consisting of a hardenable adhesive (12) which is painted onto a floor base (10) in a continuous layer, and covering elements (16) consisting of wood or a wood material that are joined to the adhesive in its entirety by their surface (14) to be glued. According to the invention, the adhesive layer (12) has a thickness of 0.5 to 5 mm and the combined tension and shear strength of the adhesive (12), in its hardened state, is les than that of the floor base (10) and is at most 1.2 N/mm2, in order to obtain a floor covering with excellent dimensional stability.
