The invention relates to a novel covering, especially a floor covering or similar, based on panels (9, 9') made of wood or a derived timber product, especially (decor) laminated panels of wood or derived timber products, with a carrier on the underside and a wear layer on the visible side. Said panels are adhesively supported, can be arranged laterally and adjacently, and are provided with laterally, optionally mutually latchable or clickable positive locking elements such as grooves (92) and tongues (91). The covering is characterised in that the groove(s) (92) and/or the tongues (91) of individual panels (9, 9') or individual surface areas thereof (921 925; 911 915) is/are provided with a filling, and a coating (95) with an extrusion (96) or similar made adhesive properties during the lateral adjacent assembly of the panels (9, 9') which is carried out by means of the groove(s) (92) and tongue(s) thereof, and/or made out of an adhesive activator which initiates or activates adhesive properties. The invention also relates to the panels used for the covering and production thereof.
