Oil is recommended for timber due to its ability to enhance and protect the wood's natural beauty and durability. When applied to timber surfaces, oil penetrates deeply, nourishing and moisturizing the wood fibers, which helps prevent cracking, splitting, and warping. The oil forms a protective layer that repels moisture, reducing the risk of decay and rot. Unlike varnishes or paints, oil allows the timber to breathe, preventing peeling or blistering over time. Furthermore, reapplying oil periodically is straightforward, making it a practical and sustainable choice for maintaining timber's appearance and structural integrity, thus prolonging the life of wooden surfaces.
