Which of the following is a method of finishing wood?

Waxing is indeed a recognized method for finishing wood surfaces. This technique involves applying a wax product to the wood, which serves to create a protective layer. Wax can enhance the natural beauty of the wood by adding a subtle sheen and warmth, while also providing some degree of water resistance and protection against dirt and dust.

Waxing is particularly valued for its ease of application and the fact that it can be easily reapplied or removed, allowing for maintenance without stripping previous finishes. This makes it a popular choice for furniture and decorative wooden items.

While varnishing, staining, and polishing are also methods used for finishing wood, they serve different purposes or provide different types of finishes. Varnishing, for instance, generally creates a hard protective film on the wood, while staining is used more for coloring the wood rather than providing a protective coat. Polishing often involves applying a compound that enhances surface shine but doesn’t necessarily provide a protective finish like waxing does. Therefore, waxing specifically stands out as a method focused on maintaining and enhancing the wood's natural look.
