Adirondacks that are bare will most likely turn a soft silvery grey. You may wish to sand these Adirondacks once per year, ever so marginally, using a 150 or 180 grit sandpaper. That is only with the objective of "knocking down" any uneven fuzzy feed which may naturally occur due to exposure to the elements. It will also eliminate any larger materials that separate out and may cause splinters. In addition, it gives a look that is sleek as well as to the Adirondack furniture. Do not sand during the silver to expose the natural colour of the timber. The aim just isn't to take out the aging that is silver but to just maintain it easy and looking great!
