Made in the UKCan you stain pressure treated wood?
Yes, you can stain pressure treated wood, but there are important factors to consider for the best results.
Pressure-treated timber is a versatile and durable material commonly used for outdoor projects like exterior wooden buildings, decking, fences, and garden furniture. While it’s designed to withstand the elements, many people wonder if they can enhance its appearance and longevity by applying a wood stain or paint. The good news is that staining pressure-treated timber is not only possible but also an excellent way to protect it further and achieve a polished look. Whether you're planning a DIY project or maintaining existing woodwork, understanding how to stain pressure-treated wood can help you get the best results.
How long should I wait before staining?
Pressure treated timber contains preservatives with high moisture content. Allow it to dry for several weeks to months. A simple test is to sprinkle water on the surface—if it soaks in, the wood is ready; if it beads up, wait longer.
What type of stain should I use?
All of our water-based stains and paints so are ideal for pressure-treated timber. They dry quickly, are easy to clean up, and have low VOC emissions. So they are specifically designed for pressure treated wood to ensure proper adhesion and longevity. See below for our recommended ranges, these include Royal Exterior, Wood Stain and Protect, Timber Eco Shield and Shed and Fence.
How should I prepare the wood?
Clean the pressure treated surface with mild detergent and water to remove dirt and residue. Lightly sanding the surface can help the stain penetrate better.
How do I apply the stain?
Use a brush, roller, or sprayer (check individual product ranges for spraying advice), applying an even coat in the direction of the grain. Water-based stains dry quickly, allowing multiple coats in a day if needed.
How often should I reapply the stain?
Reapply stain to pressure treated surfaces every couple of years to maintain protection against moisture and UV damage. Regular cleaning and touch-ups will help keep the pressure treated wood looking its best.
