The Ultimate Protection Decking Stain Willow 5L from Ronseal is a high-performance exterior decking stain in a stylish Willow shade that not only enhances the natural beauty of timber but also delivers robust protection against weathering and everyday wear on outdoor wood. Its advanced formula is designed to last twice as long as standard decking stains, resist scuffs, scratches and heavy foot traffic, and includes added slip resistance for safer surfaces, while soaking deep into both softwood and hardwood decking to help maintain durability and colour throughout the seasons. Rainproof in around 90 minutes once applied, this water-based stain showcases wood grain with rich colour, helps keep decking looking fresh year-round and is ideal for restoring or protecting garden decking exposed to the elements.
