A wedge levelling system for aligning surface coverings includes a tab with a substantially flat base and a vertical member extending away from a central area of the top surface of the base. The base includes beveled feet portions on opposite sides for insertion under lower surfaces of adjacent surface coverings, with the vertical member extending between the tiles. The vertical member is attached to the base with frangible leg. The vertical member includes an opening spaced so as to be above two adjacent tiles. When a wedge is inserted and held in the opening and presses down, the tiles are pushed downwardly toward a surface upon which they are being laid to properly align the edges thereof until the tiles are set, the wedge removed and the vertical member broken off at the frangible leg portions.

An assembly apparatus for assembling a floor panel can include a platform to support a base layer and a top layer of the floor panel. The platform can include a first wall configured to contact a first edge of the base layer and a first edge of the top layer. The platform can further include second wall adjacent to the first wall and configured to contact a second edge of the base layer and a second edge of the top layer. A sensor unit can determine whether the first edge of the base layer is aligned with the first edge of the top layer, and whether the second edge of the base layer is aligned with the second edge of the top layer.

Included are methods for sealing seams of resilient surface covering including the application of a curable composition at a seam and applying radiation to the curable composition. The radiation may be any suitable source such as UV or visible light.

The disclosure provides a flooring tool including two or more block members each having a length, a width, and a depth, attached to another block member, one or more attachments for holding the block members together, two block members comprising a gap between them, the gap between about ¼ inch to about 1.5 inches wide, one or more attachments for holding a piece of flooring between two block members in the gap and wherein the two block members comprising the gap are between about 8 inches to about 24 inches long, about 1 inch to about 6 inches wide, and about 1 inch to about 6 inches thick.

Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein a total width of tongue varies in a longitudinal direction of the tongue.
