Sealing untreated wood involves using a water-repellent sealant or wood preservative. Apply evenly with a brush or sprayer, ensuring full coverage. Allow adequate drying time between coats. Regular inspections and reapplications are crucial to maintain protection against moisture and decay.
The most common type of wood protector is a polyurethane varnish, which is basically like covering your wood cabinets in thin–but strong–plastic. You can put a poly varnish on floors, cabinets, and pretty much any wood piece that you want to protect.
