Waterproofing the inside of a wooden box can be achieved by applying a coat of waterproof sealant like epoxy or polyurethane. First, sand the interior surfaces smoothly, then clean off any dust. Apply the sealant evenly with a brush or roller, ensuring all corners and edges are covered. For extra protection, consider adding multiple coats once the previous layer has dried completely. This will guard against moisture and extend the box’s durability.
