Deck treatment

Almost done powerwashing the deck -- about 1,500 SF. Deck is constructed of what I believe to be pressure treated wood. Looking for advice on what to use for finish. Waterseal? Deck stain? It was unfinished/unprotected by the previous owner. Will one coat cover and protect? I don't want to do this for another four years.
TIA

Thompsons and the like are less than useless. If you're going to put something on it, a *good* solid pigmented deck stain is the best, IMO. If it's in *really* good shape you may get away with a semi-transparent stain. This is one area that you get what you pay for. With 1500sq. ft. you're going to pay.

Good luck with that.

Any experience with Behr (easily available at HD)? I like the semi-transparent look, but am I likely to buy some extra time with a solid?

Yes, I have it on some PT furniture I built 5 years ago. It does were off after while and you need to recoat it every couple years. Remember it is outdoors and maintenance is Mandatory, no getting around that.

--------------------------------------- If it is actually P/T lumber, I pass.
If not, consider Cetol.
One coat will not be enough. You will do it annually. It will be costly since at 1,500 sqft, the deck is larger than many homes.
Have fun.

I'm not a fan of Behr. I prefer SW or BM, for most paints. For decks I understand there are better out there, but this stuff can get *expensive*. It's been said that you'll spend $10/year/gallon. If you want it to last four years, spend $40/gallon.

AMEN! I just put some Olympic waterseal on for a client. She had purchased it and told me to clean the deck and install that. I bit my tongue, kept my mouth shut, and just did it for her. I'm sure I'll be called back next year for a replay.

Both solids and the top-of-the-line semi-transparents (with extra oxides to shield the wood from UV) will buy you extra time and -definitely- are worth the slight extra price at purchase time. I, too, prefer the semis for the actual grain showing through.
OTOH, if you -like- redoing your deck finish annually, you could probably get away with a cheaper stain/finish.

I recommend Flood (www.flood.com) CWF-UV5. (They have a weaker product, too.) Comes transparent, if your wood is in good condition, or a few tints if it is not and you need to hide stuff. Guaranteed 3 years on horizontal surfaces and 5 years on vertical surfaces. Goes on easily with a roller. Five gallons is about $100 and should cover 1500 sq. ft. easily. YMMV

Semi-transparent Cabot Decking stain (comes in several colors). Soak the end grain areas well. Ideal deck sizes are about 400 sf, just to keep maintenance under control. If there were any mildew/moss/algae, you may want some additives to the stain. Good luck--You got a big job ahead.

I put Olympic Maximum tinted waterproofing sealer on a new cedar fence about 4-1/2 to 5 years ago. We also cleaned our deck and used the same product on it. Until then we had been in the two year cycle of using the plain old Olympic sealer on the deck. We sold the house but we drove by it about a month ago and the fence still looked great. Maximum isn't the Olympic stuff you buy in the five-quart can for $17. We paid about $140 for five gallon cans but it looks like it is worth it.
