Hard Adirondacks that are unfinished will often change a soft silvery gray. You are going to want to sand these hardAdirondacks once annually, ever so marginally, with a 150 or 180 grit sand-paper. This is solely with the objective of "knocking down" any irregular blurry materials that may naturally occur as a result of exposure to the elements. It will likewise eliminate any bigger fibres that separate away and may cause splinters. In addition, it provides a look that is sleek and even to the Adirondack furniture. Don't sand through the gold to show the natural shade of the wood. The intent just isn't to take away the aging that is silver but to only keep it sleek and looking great!
