You can protect your outdoor wood shutters from the elements and enhance their overall appearance by finishing them with the appropriate coatings. Before you begin the application process, understand a pair of important points. Exterior shutters are exposed to consistent moisture and varying temperatures. You must apply a secondary topcoat of varnish or polyurethane wood sealer after you apply the stain, or the wood will ultimately take on a weathered, gray appearance. In addition, you must eliminate the old sealer prior to application, or you will have problems with absorption.
