Abstract
A flooring material (1) comprises a base portion (2) having a coating portion (3) which imparts improved stain resistance to the flooring material (1) and is positioned in contact with an upper surface of the base portion (2). The coating portion (3) creates an upper surface of the flooring material (1). A particulate material (6) is embedded in the coating material (3) and at least partially penetrates the base portion (2). The particulate material (6) provides a roughened effect to the upper surface of the flooring material (1) and protects the coating from wear. The coating (3) merges into the base portion (2) where they meet at joint (4) to form a stratified portion (5).
