Abstract
Abstract A wooden floor is laid by placing preformed groups of end cuts of timber on a base, pouring adhesive between the groups of end cuts and polishing the hardened surface of the floor to expose the cross grain of the timber. The groups of end cuts are formed by securing length of timber in a vertical bundle, pouring liquid adhesive into the top of the bundle to fill the gaps between the lengths of timber, and, when said adhesive has hardened, cutting the bundle transversely into slices.
