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

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.

http://www.ebuild.com/product-detail...rds/319691.hwx

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.

Thanks, I'll check it out.

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.

Double up on your joists. 9" spacing would make your deck solid as a rock.
The fishing pier at Fort Clinch is done with 5/4 on 12 " centers. I didn't
notice any sagging or bounciness.

I looked at everything when I decked my pontoon boat 20 years ago.
We
had a Wolman plant here at the time and they offered to pressure
treat
any plywood I would bring them but the guy who ran the plant said PT
really only protects it from bugs. If water is your issue, save your
money. I ended up with MDO plywood (one side) and it is still going
strong after 20 years in salt water. That is basically 7 layer
exterior grade plywood with one MDF layer. You would probably have
the
same luck with BC
The main thing is to be sure everything is sealed before you put it
in
and seal all penetrations. The only bad spot I have found in my
current rehab is from an unsealed penetration.
Cut all of your pieces to size, paint them on all 6 sides with 2
coats then install them. Paint it again to cover the screws. Bristol
Palin will be running for president before that plywood goes bad.

I worked on a sailboat once that had a PT plywood sole and where it
met, the aluminium mast was badly pitted.
I thought it may have been caused by the cyanic acid?


Nope, the copper is not friendly to aluminum in a wet inviroment.
Is ther copper in pressure treated plywood?


Yup. Used to be copper arsenate (CCA). Now it is a copper only
solution.
http://www.strongtie.com/productuse/PTWoodFAQs.html

Ah galvanic action. Good reason not to butt up to, bolt or clamp to
aluminum.
Thanks.


It may be somewhat of a concern but not a huge problem. These aluminum
brackets have been on my .8 CCA PT dock for over 20 years

The problem with the Trex type stuff is the span is about 60% of what

That's too far for composites like Trex. 16" is the absolute minimum.

I went down to look and the span on the 1.5" Trex is 16". It is very

While I was there I came upon the dunked Dodge.

I looked on the Trex site for 1.5" stuff and couldn't find any. Do you think
they still make it?
