I’ve had my cabin in Dorrington for 18 years now. Every two to three years I have cleaned and applied a couple different stain/sealant products. But no matter how carefully I prepare, following every recommended step, my deck’s appearance declines rapidly in a year or two. So after talking to a landscape architect, and reading many websites, I took a totally different tack two years ago. I sanded my deck smooth using the same equipment used for hardwood floors. I applied nothing. I am just letting it turn naturally gray. Two years later my bare deck looks good, not great. But it looks FAR better after two years compared to any of the stain/sealants that I have used previously. Time will tell, but for now I’m very pleased that I did not apply anything.
