PT + Aluminum Coil Stock: Protection?

Tinstaafl

Has anyone come up with a known-effective and reasonable way to protect coil stock from the nasty stuff in today's PT wood? Specifically, for wrapping posts.

I'm getting ready to do a few, and the best (and royal PITA) "maybe" I've come up with is to wrap first with vinyl flashing, then apply the aluminum.

HO's budget won't handle vinyl sleeves. <sigh>

EIDOL

all you need to do is isolate the coil stock from the wood with tar paper and use stainless staples
It's the metals that's it the wood are causing electrolyse to occur you know dissimular metal one will attack the other or some zinc annodes

Check your end tags.
MCA is not so picky, supposed
to be the same as CCA for
fasteners and flashing.

The culprit is copper. Roofing felt might work, but it is permeable. It would be nice to hear from someone who's used it and had no problems for several years--but of course the new recipes aren't really old enough yet for much of a sampling in that respect.

ACQ.

I know Grace makes a sticky-backed product for ledger boards & joists, but I can only imagine what a joy it would be to apply that to a post.

I have to admit to being somewhat dumbfounded that the industry in general seems to have just rolled over and adopted a PT formula solution that blows away a very common and popular industry standard (wrapping) without coming up with a reasonable solution for us guys on the front lines.

loneframer

In my opinion, they have.

You could staple it up without
peeling the back.
It's gonna be trapped anyway.

Don't worry, it is
going away soon.
MCA will replace it........


for a while.

Yeah. Out here, we're on a beer budget.

Tinstaafl

With SS staples, right?

I've never seen that product; don't even know if anyone around here carries it. I have the feeling that you'd wind up with some pretty rounded corners.


Yeah. I remember when they told us that milk was bad for us, too.

I've been using I&W. If you take the roll and run it through the band saw and cut it somewhere in the 14" range it should get you in the ball park for a 4x4. Cut in 8' sections it's not too bad unless extremely warm.

Flashing tape is expensive...advantage is, is that it is thinner and a little more user friendly

I just wrapped some 4x4s in 2 piece vinyl from yardcrafter...I don't care for their railing...kinda cheap, but the sleeves did what they were supposed to. $55 for a 9' sleeve. By the time you wrap the post in something and then wrap it in aluminum too.....almost not worth the PITA

What's your blade look like after that?

I actually had considered that, but felt that brake-able vinyl would at the least be a bit more forgiving if I don't hit it dead on when applying to the post.

Do you have some I&W jobs that are old enough that you feel confident that's good for the long run?

Use vinyl coil! It won't dent as easily, won't corrode, comes with double face tape, and you can make it in one piece.

Tinstaafl

It also has a high expansion coefficient, tends not to hold its [bent] shape very well over time, and I don't trust tape to hold up indefinitely in an exterior environment.

No jobs over 4 years old, but always felt good when I walked away...never thought twice about it...what could really happen

Are they new posts? Older ones are a royal PITA if they have any twists or crowns in them.....I don't think I'll be wrapping anymore in aluminum unless I have too...those sleeves were too easy. They have just enough slop in them to take up any twists or crowns.

6X6s in this pic will be getting paint. My brother does the majority of my wrapping....he does soem really nice work, but is pretty slow. He would be there the rest of the sumer wrapping the 6x6s...the deck runs the lenght of the house on the other side.

I agree with tar paper. Allows a bit of air space and a drainage plane.

PA woodbutcher

Nice brake...is that what your using? Will be buying a new one this summer. Have a house to do in vinyl complete with windows and new roof.

I have used tar paper under quite a few aluminum wrap jobs.

3 windows in a block building down the street, still look like new after 4 years.

I have not been past the rest in a while but, I suspect they are doing just fine.

Tinstaafl

I think that's about the age of the current PT recipe, so... so far, so good. What could happen? Well, how about after 5-10 years, the wrap turns into doggie doo-doo? I'd like to think that my work will outlast me.

Tell me about it. BTDT. But these are new 6x6, incredibly straight. In a way, that makes it even more of an insult to have to muck 'em up with extra junk.

Heckuva deck job; you get three envy credits.

See my comment above regarding vinyl. I could be wrong; it's happened once or twice before.

PT for windows? Gotta admit, I've never tried that.

WarnerConstInc.

Not for the whole window. I had to build them out on the outside because of a few reasons. It was quite the PIA.
