The waiting period for oil applied to wood to completely harden and become water-resistant depends on the type of oil used and environmental conditions. Generally, it takes 8 to 24 hours for the oil to dry properly and, once all necessary coats have been applied, 15 to 21 days for the finish to reach complete cure. It's important to consult the technical data sheet for precise information on the curing time of the oil used. During this period, no maintenance should be performed on the wood.
