Applying varnish to wood surfaces serves multiple critical functions, with one of the primary purposes being to provide a protective finish against scratches, moisture, and other environmental effects. Varnish forms a hard, durable layer on the wood that shields it from physical damage, thus helping to maintain the wood's integrity over time. This protective barrier reduces the likelihood of wear and tear that can occur from everyday use, ensuring the longevity and appearance of the wood.

While varnish can enhance the wood's color and grain, its fundamental role is not solely focused on aesthetics. Furthermore, varnish does not change the wood's shape; instead, it adheres to the surface, allowing the wood to retain its original dimensions. Lastly, the drying process of varnish is primarily a chemical reaction rather than a measure to expedite drying. The application of varnish requires careful timing and environmental considerations to achieve the best results, rather than simply being aimed at speeding up drying.
