After you have picked a stain for the wood flooring in your home, you need to varnish the solid oak flooring so that it will repel water and dirt. This makes it easier to clean up. The higher the gloss of the varnish, however, the more likely the mars in the floor are seen. You are better off to go with a natural finish for varnish or a eggshell varnish for the sealing of your wood flooring in your home as this will still be easy to keep clean and will show less marks, dents and any other mars in the wood.
