Hard Adirondacks that are unfinished may often turn a delicate silvery grey. You are going to want to mud these Adirondacks once annually, ever-so marginally, having a 150 or 180-grit sandpaper. This really is just with the aim of "knocking down" any uneven blurry grain that may naturally occur as an effect of exposure to the elements. It will likewise eliminate any larger materials that can cause splinters and separate out. In addition, it offers an even and smooth appearance to the Adirondack furniture. Don't sand through the gold to show the natural shade of the timber. The motive just isn't to remove the patina that is silver but to just keep it smooth and looking grand!
