What a good idea! Instead of buying new replacement boards for your deck why not check out the flip side first? The boards are probably just as good looking on the other side as when they were first purchased … and with a little effort (ok, maybe a bit of effort) you could turn that frown upside down by putting the good side right side up!
Update: I heard from a source that this might not be the best idea after all. The thought is that you should lay the boards with the curve of the grain pointing up because over time the boards may cup and hold water when it rains.
What do you think?
