Can you apply wax over poly?

Yes, you can apply wax over a polyurethane finish, but it's important to ensure that the poly is fully cured before doing so. Wax can add a layer of protection and enhance the gloss of the finish. However, keep in mind that wax may require periodic reapplication and can alter the appearance of the polyurethane. Always test on a small, inconspicuous area first to ensure compatibility.
