Abstract
A floor panel for forming a floor covering comprises a substrate consisting of at least two substrate layers differing in density and, on at least one pair of opposite edges, is provided with coupling parts of the so-called push-lock type. Vertically active locking surfaces, where they cooperate in the coupled condition of two of such floor panels, define a tangent line which is horizontal or does not deviate more than 50 degrees from the horizontal. The locking surfaces are situated closer to the upper side of the first substrate layer than to the lower side of the first substrate layer.
