Topic tags/keywords: question

It has been 4 months since I completed the building of my deck. I used PT southern yellow pine in it’s construction and I was waiting for the wood to dry before applying a preservative. I have been checking the dryness of the wood by pouring some water onto the wood; if it gets absorbed, it’s dry; if it puddles on the surface, it is still to wet. The weather has not been cooperating with rain usually every 4 or 5 days; not allowing the wood to dry enough before applying a preservative.
So the question(s) I have are; when can I apply my preservative? Do I have to wait until the wood is bone dry? What preservative should I use; water or oil base? Which is best; Thompson’s water seal, Olympic, other? What is the best way to apply; sprayer, paint roller, other? I want something with a stain in it to darken the wood a bit. Do I need a pre-conditioner?

Sikkins SRD is the best we’ve found. A couple coats will last several years. I’d wait til the deck boards are dry. Then, apply the Sikkens with a medium nap roller. Wait 24 hrs and hit it again.
Home Depot carries it, as does Amazon.

FWIW, I did the same thing years ago, waited to seal my deck (which was cedar). House was built in fall, so I planned to do it in the spring. It was south-facing, & by spring had already gotten pretty gray. In talking to a contractor, I was told that there’s really no benefit to waiting, because unless you’re treating all sides, the board will just dry through the untreated bottom side anyway. Only relaying what I heard, so take it as you wish.

Two things are needed for a NEW deck. First the wood should be as dry as possible, second sand the surface lightly to remove any contaminates and remove the surface fiber compression caused when the wood was planed. The latter can prevent or slow absorption of the sealer creating a surface finish that peals off in spots.
For application a roller works but I have also had good results with the flat applicators. Power spraying might do a better job of getting the finish between the boards and would be faster, especially if you have an extension for the spray tip so you don’t have work bent over. Of course you need to mask everything you don’t want sprayed first.

Over the past 25 years I have tried a number of different deck treatments. Thompsons is the least effective and I’m not familiar with Sikkins brand but I question that it is any better than some of the others. The best one I found was Behr’s deck sealers and stains. None of them last more than 3 years. In some cases you can go 4 years but that usually means more work cleaning and prepping before applying the next coat. ie. power washing, using a cleaning agent and bleaching.
Climate can make a big difference. In sunny locations the sun drys the finish out and you get cracks in the wood that let moisture in. In wet climates like the Pacific Northwest the rain causes mold and mildew to discolor the surface and break down the finish so it needs to be cleaned (power washed) every Spring.
On my current deck (in western Oregon) after 15 years I gave up on keeping the natural wood look due to stains and other blemishes that developed and could not be easily removed. The deck was surface nailed/screwed so it could not be sanded. I used a deck paint, Rust-Oleum brand worked better than Behr’s Restore. Even that needs refinishing every 2 to 3 years.

no deck is sealed unless you seal the complete plank, the cut ends, the top, bottom, sides ect.

I build a lot of decks, mostly with composites, but when we do use real wood, we saturate the lumber in a vat with a water proofing product, then once installed, all cuts are resealed as they are made, and then the deck is give another bath.

Most seal only the top of the walk deck plank, it serves no purpose, especially in four seasons area, moisture ect, still is the enemy.
good luck wiyh it

I’m in my twilight years so, I’m not looking to refinish every 2,3 or 4 years. Building this deck has been a back breaking job for me. I’m surprised I even got it done. I’ll be looking for the best long lasting finish that I can spray on and be done with it. I’ll look into Sikkens and Behr. Thanks for all your input.

I was going to try to come up with a deck joke but you being in your twilight years wouldn’t remember it anyway. I guess I could have said my deck is bigger than your deck…

Or, perhaps that, if truly in the twilight years, preservation of the underside of the deck might be of equal, or greater, importance.

Downunder, Ron, it’s my preference to use a good quality natural oil at one coat a week for a month the one coat a month for six then every six months if you want it to last in the elements for a long time as the oil is heaps cheaper compared to rebuilding the deck again in five years.

This is interesting. So, if you seal before you actually install, I take it the wood is still wet?
