Larch Lye Treated Brushed White Oil by Mafi is originally a warm honey colour with a beautiful vivid surface appearance, full of character. Mafi’s Lye Treatment on the surface of the wood creates a soft grey/white wash tint, producing a unique pale colour. Mafi floors stand out due to their longevity and robustness, and are 100% all-natural, free from harmful substances such as formaldehyde. This hand crafted, engineered board consists of three-layers with the top and bottom made of the same species, ensuring perfect balance. The middle layer is 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.
