Treated Clear Southern Yellow Pine vs. Tight-knott cedar decking

user-2409187's picture

I have a question: What is your experience with clear (knott-free) Souther Yellow Pine deck boards, face-screwed to treated SYP framing spaced 16" OC?  The deck is not shaded and sustains hours of full sun light. The current composite Fiberon brand decking has badly faded despite a 20 yr fade warranty. The dark color my client selected is partly to blame.

For various reasons composite decking is not an option. The choices are face-screwedd 1) regular pt. SYPine decking, 2) clear, p.treated, SYPine or 3) tight-knott cedar. Which product, cedar or clear treated SYP holds up better in the condition described above? Cedar will receive a clear sealant coating.

Thank you.

No help but a short rant.... (post #215356, reply #1 of 4)

I would favor SYP. My experiences are that grades are only a number, every batch of SYP RED will be different. I like to see the stack before ordering.

But [inserting rant here] I find peoples expectations of wood that is constantly exposed to the weather to often be unreasonable. Annoying even. 

Here's the deal: this is a deck. It is made of wood or other material left outdoors 24/7. Since it is subject to such exposure weathering is to be expected, if you can't embrace that you need to readjust your expectations to reflect reality.

Why does everthing have to look shiny new? Silly cultural predjudices brought to you by generations of people selling dreams.... 

Rest assured user 2409187 I'm not pickin' on you or even your customer but the system that has created this attitude.

I know...I know...sigh :) But...this good client paid $10K shekels and the deck did not match the warranty set forth...so...I feel for my client. He deserves better. But what shape shall "better" take this time around. And since I am paying to have it redone (manufacturer went belly-up, I believe), I want to make sure that my promises this time around matches the expectations. So..um...thanks for your pointers. I elected to not go with 20' long special order Premium SYP planks, since I can't see them and they are non-returnable. I'm going to sort through the local supply of 16' long Prem. selection, which happens to be super dry. I'll coat the underside and edges "just to play it safe". The top gets a semi-transp. finish, which is mostly for looks. I will keep an eye on the deck and re-coat as needed. My motto: Our aim is to offer exceptional service; at a profit if we can, and at a loss if we must, but always exceptional service."  (Hey, Donald, you listening? :)

one other suggestion.. (post #215356, reply #3 of 4)

I think for micronized copper or copper azole treated SYP you must retreat all field cuts with copper napthenate or some such. Those treatments just don't seem to carry very far into the wood.

HI Mel, I have used 5/4"x 6" (post #215356, reply #4 of 4)

HI Mel, I have used 5/4"x 6" western red cedar (tight knots) for quite a few decks including my own.  It is less expensive than PT in my locale, is very stable and seems to be holding up beautifully.  Mine is 6 years old with no finish and has a soft gray color.  It is, as you know, very soft so it scratches and dents easily, but it stlll looks and feels great underfoot.  PT in my experience looks awful, cups, splits, warps, and gives nasty splinters.  Mahogany and cedar are my go-tos...  Good luck.
