The Ronseal Ultimate Decking Oil Natural 5L is a high-performance exterior decking oil in a natural finish that nourishes and protects wooden decking by penetrating deep into the wood to help prevent drying, splitting, greying and weather damage while maintaining the wood’s natural look and feel. Its advanced formula lasts twice as long as standard decking oils, becomes rainproof in about 90 minutes and offers resistance to scuffs, knocks and UV fading, giving long-lasting durability and a subtle, enhanced finish that highlights the grain of both hardwood and softwood decking. This easy-to-apply oil is ideal for preserving and beautifying exterior timber decking exposed to changing weather conditions, helping keep it looking fresh and well-maintained over time.
