Regularly inspect sealed surfaces for signs of wear or damage. Clean the wood with a gentle soap solution to remove dirt and debris. Avoid using harsh chemicals that can damage the sealer. Reapply the sealer as needed, typically every one to three years, depending on environmental exposure. Store wood products in a dry environment to prevent moisture buildup.

Do not apply sealers on wet or damp wood, as this can lead to inadequate adhesion. Avoid using products not designed for outdoor use, which may fail under harsh conditions. Ensure surfaces are clean and free from old coatings before application. Do not skip testing a small area first to check compatibility and appearance. Lastly, avoid ignoring manufacturer instructions for optimal results.
