You might be one of the countless homeowners frustrated with the annual or biannual task of cleaning and sealing your wood deck. I’m right there with you, as I have to deal with my wood deck and the stairs leading to it. It’s a wretched job that can span days. It’s no wonder you might be drawn to the composite decking displays at local home and garden shows.

Over the past three decades, I’ve been lucky enough to obtain inside information about exterior wood sealers. Add to this the knowledge I discovered while researching my “Roofing Ripoff” book exposing the shingle industry. You probably know that the sun’s ultraviolet (UV) rays are harmful, but you might not know the actual mechanism. Once you do, you grasp why deck sealers are doomed from the get go.
