Yes, you can treat untreated C16 carcassing timber yourself to help protect it from decay and insect damage. Treating the wood will provide some level of resistance to moisture and prolong its lifespan, making it more suitable for outdoor use like patio decking. Here are the steps you can follow to treat the timber:
Choose the Right Wood Preservative: There are various wood preservatives available on the market, such as wood stains, oils, and chemical treatments. Look for a preservative that is suitable for outdoor use, provides protection against water, insects, and UV rays, and is compatible with the type of wood you have.
Prepare the Wood: Before applying any treatment, make sure the wood is clean and free from any dust, dirt, or debris. You can use a brush or a pressure washer to clean the timber.
Apply the Wood Preservative: Follow the instructions provided by the manufacturer for the specific wood preservative you have chosen. Generally, you'll need to apply the preservative evenly to all sides and edges of the timber using a brush, roller, or sprayer. Ensure that you coat the wood thoroughly for maximum protection.
Allow Drying Time: After applying the treatment, let the timber dry completely according to the manufacturer's recommendations. This drying time is essential to ensure that the preservative penetrates the wood effectively.
Repeat if Necessary: Some preservatives may require multiple coats for optimal protection. Check the product instructions to determine if additional coats are needed and follow the recommended application schedule.
Maintain Regularly: Even treated wood requires maintenance over time, especially if it's exposed to harsh weather conditions. Regularly inspect the decking and reapply wood preservative as needed to keep the wood protected and looking its best.
It's essential to note that while treating the wood yourself can help improve its durability, it may not provide the same level of protection as commercially pressure-treated wood. Commercially treated wood goes through an industrial process where the preservative is forced deep into the wood fibers, offering longer-lasting and more robust protection.
If you have any doubts about the process or the type of treatment to use, consult with a professional or the wood preservative manufacturer for guidance specific to your situation. Additionally, always follow safety guidelines and use appropriate protective gear when handling and applying wood preservatives.
