...and am now looking to finish/preserve it. The deck boards are pressure treated southern pine. They are wet with the recent downpours.

What is the best way to preserve it? I was thinking Thompson’s water seal and a stain.

Should I wait for the wood to dry out before applying any finish/preservative and if so how long until it’s dry enough?

Is there an all-in-one stain/sealer?

You should replace the pressure treated SP with teak. Then, no worries

depending .. let it dry, typically PTW is wet from the get go.. it has to dry and no Thompsons is not a good choice,. Its a paraffin base. You will want a good penetrating oil sealant , Checkout a product called ” ONETIME ” Or
One Time , Film finishes of any kind do not hold up exterior and have to be sanded and stripped and renewed. Penetrating products , not the case .
For me this was a lesson hard learned, had to strip and re do over 40 pieces .

Actually your better off to leave it as is, and every year or so , give it a spray down with some deck brightner or bleach .

I had exactly the same experience as Charles. I now use opaque water based stain, which goes on like thin paint. It will look pretty good for 4 or 5 years before having to redo. Of course, that doesn’t help you if you are wanting a transparent finish. In that case, I agree with Charle’s advice. I read an article in Consumer Reports several years ago that pretty much stated wood treated with Thompson’s Water Seal didn’t hold up any better than untreated wood over a year’s time. I don’t know about now.

Thompsons is cheap which is nice but doesn’t hold up well. I did a deck in it and noticed two things. 1- u can only get one coat on it cause the second won’t absorb well 2- after about 2 months of med use it was starting to flake.
I’ve built a lot of decks and redone a lot but I haven’t stained many. If I was you I’d go to my local mom and pop hardware store and see what the recommend finishing with. They’d already know what holds up in your specific weather as well
Also I don’t resommend not finishing it with anything. Treated lumber is rot resistant not rot proof. It will eventually rot where as if it’s finished once a year or so it will last for as long as u care for it
Also I recommend u let it dry out for a few months. The longer it drys the better it will absorb the finish

I just finished a deck replacement on my home with a smooth finish pressure treated Douglas fir. I researched sealants to death before I figured out what I was looking for. I used a semi transparent stain and sealer from Olympic called Elite Woodland Oil. It has enough solids to provide some UV protection and it’s an oil base that absorbs some into the wood. I’m very happy with the results of mine, and the best part is it is thin enough that you can spray it through a cheap Harbor Freight HVLP gun if you have enough compressor. Total finishing time was about 3-4 hrs for a 10×10 with stairs.

the best way to PROTECT it is to wait. the lumber needs time to dry out some.
how long to wait would depend on location.
seems northern climates its typical to wait a year, but ive built decks in early spring- that get full sun all day- and felt it was good for finish by end of july.

Thank you all for the replys. I checked the reviews of all the different sealers/stains on the market and they all have their positive and negative reviews. I can’t rely on those reviews, so that is why I ask the question here. The one thing that everyone seems to agree on is “to wait a few months before applying any deck sealer”. I’m inclined toward Olympic, but it is expensive and has negative reviews. I too feel that an oil base sealer is needed. I guess I have a few months before I have to commit to a finish and that will put me into the coldest time of my season here on the Gulf Coast. Some products say not to apply below 50°. So far, I have spent around $1000 for a 16’x16’ deck, or about $4.00 a square foot.

Ron,

I highly recommend Flood CWF-UV5 which you can get at PPG stores. I use it for fences, decks, outdoor furniture, etc. Great stuff!
