How can wood be protected from moisture?

Applying sealants or finishes is an effective method for protecting wood from moisture because these products create a barrier on the surface of the wood. Sealants and finishes, such as varnish, polyurethane, or water-repellent preservatives, penetrate the wood fibers and fill the pores, preventing moisture from entering and causing damage like warping, splitting, or rotting. This process helps maintain the structural integrity and aesthetic appearance of the wood over time, making it suitable for both indoor and outdoor applications.

While storing wood indoors can help reduce its exposure to moisture, it does not provide direct protection to the wood itself. Untreated wood is especially vulnerable to moisture damage, and painting with oil-based paint may offer some level of protection, but it is typically not as effective as dedicated sealants or finishes designed specifically for that purpose.
