WOCA Diamond Oil has a 99% high solid content which provides an ultra-hardwearing, nearly waterproof surface. This product is used for the initial application of oil, and subsequent coats. This oil penetrates the fibers of the wood, hardens and strengthens the wood from within, providing a durable wear surface. Floors treated with WOCA Master Oil can be easily spot repaired unlike conventional polyurethane coated floors. Coverage: 215 sqft/liter for soft woods, 270 sqft/liter on hard woods.
