Here in the Pacific NW, we have a problem with dampness. My deck was completely gray, and now with a lot of bleaching, I've gotten rid of the mold/mildew. The deck is ready for the brightener, which I already have. I put a little bit of the brightener in one place, and it made the pressure treated wood (probably southern pine) look like new.
I don't want to brighten it though till I know what to use the protect/stain the deck with. I want low maintenance. Cabot SPF 48 is supposed to last 3-4 years. Penofin for pressure-treated wood seems to have to be recoated fairly frequently, as does TWP.
I've heard of PlastIron. Do they still exist? I've gone to their website at:
, and it doesn't seem to work, and they've not responded to my email/contacts.
What is there out there that protects pressure-treated wood decks for a really long time?
