Mafi Cor Ash Grey Oil is a modern and hard-wearing floor with a light grey appearance. Mafi floors stand out due to their longevity and robustness and are 100% all-natural, free from harmful substances such as formaldehyde. This handcrafted, engineered board consists of three-layers with the top and bottom made of the same species, ensuring perfect balance. The middle layer is a conifer and runs across the grain for added strength. The layers are glued together with an all-natural glue of water, lime and plant acid.
