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 (décor) 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.

The invention claimed is: 1. A floor covering comprising: a first panel having a laterally mounted interlocking first element comprising a groove formed at an edge of the first panel with lateral groove flank surfaces extending obliquely outwardly, and an undercut at a groove entry; the edge of the first panel above the groove entry being offset from the edge of the first panel below the groove entry; the first element including a water activatable adhesive material, wherein said adhesive material is in a passive state at room temperature and transitions from the passive state to an active state at room temperature upon contact with water or water moisture and stabilizes by extraction of water; a second panel with a second laterally mounted interlocking element comprising a tongue extending from an edge of the second panel and having lateral tongue flank surfaces tapering obliquely, the tongue including a neck portion engaging the undercut, wherein the edge of the second panel defines a recess above the neck of the tongue, the edge of the first panel below the entry to the groove and the edge of the second panel below the tongue are spaced apart when the first panel and the second panel are engaged, the second element including said adhesive material; the groove flank surfaces and the tongue flank surfaces and the tongue flank surface receiving said adhesive material, and said adhesive material is coated on said first element groove, said second element tongue, or both said first element groove and said second element tongue; and wherein the first and second panels comprise a timber material, said first and second panels having complementary lateral positive mechanically interlocking elements configured for mutual snap-in engagement between each other. 2. The covering according to claim 1, wherein the adhesive is laterally applied to a contact surface of the groove flank surfaces and the tongue flank surfaces adjoining a primary surface of the panels. 3. The covering according to claim 1, wherein the adhesive material is selected from the group consisting of a polyvinyl acetate, a starch-based adhesive, a protein-based adhesive, and mixtures thereof. 4. The covering according to claim 1, wherein the edge of the second panel defines a recess proximate and above the neck of the tongue.
