The Ronseal Ultimate Protection Deck Stain Dark Oak 5L is a rich, deep brown decking stain that not only enhances the natural woodgrain of your outdoor timber but also provides robust, long-lasting protection against weather and everyday wear. Designed for use on both hardwood and softwood decking, this water-based stain soaks into the wood to help resist scuffs, scratches and heavy foot traffic while remaining slip-resistant and tough through winter conditions. It lasts twice as long as standard decking stains, becomes rainproof in about 90 minutes and showcases a stylish matt finish that keeps your deck looking attractive and well-maintained all year round.
