You’ve decided that oil is a good finish, and lucky for you, it’s one of the easiest to apply.
The first thing you should do is identify the type of wood you’re working with. Really porous woods may not do well with oil because the wood soaks it all up leaving very little on the surface. Getting an even coat is difficult.
Once you’ve identified your wood, sand the surface gently to remove any dirt or grime before you apply the oil. Work from coarse sandpaper to fine to ensure you won’t have any deep scratches left on the surface of the wood.
Apply the oil gently with a high-quality rag. Lower quality rags can pill and leave those annoying little pieces of fuzz everywhere. Wipe up the excess and make sure to clean your clothes carefully.
Allow the proper amount of time to dry before adding a second coat. The drying time will depend on the product you’re using. Be sure to read the instructions thoroughly.
