I was wondering abotu using salt-treated plywood on the Marquis
deck.
I'm not a feared of paying for marine grade, but Jimmy the
carpenter
told me that the newer salt treated woods are about as worthy as
marine grade at a fraction of the cost. So, what's the opinion?


I'm even wondering abotu using hybrid decking like you'd use on a
porch. synthetic mylar etc mixed with wood. The stuff is weather
resistant as all get out!

Does the composite stuff come in sheets, or were you going to use
boards, like
this:http://tinyurl.com/29auaun

I'm thinking of resurfacing my deck with that stuff. Expensive stuff
though.

John, this is the crap we used on our front porch. It faces the west
and gets all the harsh summer sun and the rain etc. We redid our
porch
twice with treated tongue and groove pine and it was rotting in 5
years. Enough was enough. This stuff is extremely durable, looks and
feels and acts like wood. We've been satisfied for 10 years now.

So I was thinking of using this stuff decking the boat from side to
side instead of long ways from bow to stern.


Just a thought, though.

The problem with the Trex type stuff is the span is about 60% of what
you can get with the same size wood and it is heavy.
I have some as a ring around the base of my console and it does hold
up well but there is no span issue there.

I'm wanting to resurface my deck. The span would be about 18". Think
that's
enough?

That's too far for composites like Trex. 16" is the absolute minimum.
They can sag with the heat.

Crap. Not good news. That would mean a lot more than simple resurfacing.

They do make Trex type decking in 1.5" thickness that will span
farther. You need to go to a real lumber yard tho, not HD/Lowes.
We used it to replace dock lumber at our community boat ramp.

If you have 24" centers on the joists, just add a stringer in between and
make it 12" centers. Fairly easy. Is what I did on my deck, changing from
redwood to Trex. and kept the same base piling spacing.

I may not be in as bad a shape as I thought. My uncalibrated eyeballs and large
feet gave me the 18" estimate. A ruler gives me 16" centers.
