The Ronseal Ultimate Decking Oil Teak 5L is a premium exterior wood oil that deeply nourishes and protects garden decking in a rich teak-toned finish, helping to prevent your wood from drying out while enhancing its natural beauty and grain. Its advanced formula is designed to last twice as long as standard decking oils, resist greying, splitting, scuffing and knocks, and becomes rainproof in about 90 minutes, so your deck stays durable and attractive with less frequent maintenance. Suitable for use on both hardwood and softwood decking, this water-based oil soaks into the timber to provide long-lasting weather protection and a subtle, matt finish that highlights the warmth and character of outdoor wood.
