It depends on whether you are looking for aesthetics or durability.
A topcoat will provide greater durability and protection than wax finishes over time.
While wax finishes are lovely, they typically show wear (fingerprints) and are not permanent, requiring semi-annual to annual maintenance.
Wax is a low durability finish. It’s fine for a decorative piece that will receive light traffic. It is absolutely not strong enough for tables, kitchen cabinets, or other surfaces that will see frequent use.
Wax takes a bit of elbow grease to apply.
Furthermore, nothing adheres well to wax, which can impact future finish changes. Even though there is internet chatter about removing wax with 3rd party products or mineral spirits, the risk of a failure in re-coating over a wax finish is very high and sometimes impossible.
If you love a wax finish, try General Finishes Satin Finishing Wax. If you want the look and feel of wax with more durability, use our General Finishes Flat Out Flat Topcoat. For even more protection, use General Finishes High Performance Topcoat.
