i am stuggling with these new presure treated post. copper sulfate is what they are using for the presurvative. well i have used a Bin(shellac based)primer, oil primer will not stick, 100% acrylic primer sticks well but terible bleading, same with bonding primer. so if i buy post and let sit out to dry for 6 month then it seems to help. but keeping a large inventory sucks because i have all that money tied up just sitting. From the lumber yard the comes so wet.
Does any one have a solution for painting?

Keep UP hun! (see Donna's 'self-educate' thread . . . not to mention the other PT thread . . . )
Bruce,
they are not the same as they ever were.
They are now being treated with copper instead of arsnic due to someone whining about the dangers of arsnic.
(As an aside to this, how many construction people do you know who've handled the stuff for UNtold years and have suffered from arsnic poisioning?????)
ANY~way . . . because of the new treatment, (which has been in use for over a year or so now) you must buy the new 'coated' hardware, which OF COURSE, they are now making with different heads than the old phillips, the new ones require square heads and star drive-bits, ~BUY NOW~SAVE LATER~ The old deck screws for example are useless and will literally deteriorate if used.
Also, the green bleeds thru primer pretty bad. It takes 2-3 coats. I typically thin my first coat of latex primer and let it penetrate. then the second and sometimes third coat go on thicker. I have'nt noticed any problem with 'green' bleeding in lighter-coloured finish coats . . . but I've only had two such frames requiring painting since the change.
I have one to be finished white to do soon . . . will let you know how it goes.
For more info on the new treated lumber, see the folks at your lumber yard.

For the last few years that my shop was still active, I quit using wood posts entirely, and switched to PVC. The only exceptions were wooden posts that had to look like wood, and pressure treated posts never filled that bill anyway.
I found a vinyl fence company that was also a supplier of PVC extrusions in the same sizes as diminsional lumber. Besides 4x4 and 6x6 posts they also had 2x6, 2x4, and several sizes of 1x. There is a wide range of top caps for the posts from plain caps to really elaborate finials. Use the right primer, and PVC takes paint like a champ. By using some simple router jointry, the stuff is really simple to work with. Face material like 1/2" or 3/4" "Trovicel" or similar stuff, was a perfect companion to the PVC.
Believe me..... a 6x6 PVC post filled with concrete is a very formidable structure. Won't warp or twist, will never rot out, and the gardener with his weed eater won't chew away the post at the ground.

i would not be opposed to using pvc filled with concrete for a permanent structure, as a matter of fact that would be awesome. but for temp we would still have to go with treated wood.
and sheila i have noticed the coated screws in the local home depot lately and they glide right in. i do know the older galvanized deck screws are all rusting out and breaking off on some older temp signs we have had to take down.
still havnt noticed this green stuff on posts yet but i guess ill know when it hits montgomey!
does no one care about the poor signguy anymore, damn people stop messing with stuff

Jean, to answer your question on primers. When I first started using PVC posts and frames, I contaced Tom Yates, technical director at 1-Shot. He recommended Chromatic Acrylic Ticoat, or 1-Shot 5005 White Acrylic Bonding Primer. I followed his advice and never had any problems. 1-Shot also makes their 5004 Vinyl Primer, which works well for interior applications, but is not recommended for exterior use.

Have any of your PT jobs been painted ones, or do you just leave them natural??
If you have'nt had any call for painted frame/posts, that may be why you have'nt particularly noticed the green lumber, but the new lumber IS there at your lumber yard. There is no more of the 'old' stuff.
The new copper treated looks pretty much exactly like the old arsnic treated . . .although some spots have a much more greener 'cast' to them . . . but it looks basically the same.
But you really see the green when you prime the new lumber, the copper formula which they used to treat the wood bleeds thru REALLY heavily in most spots leaving big mint-to-sea-foam coloured-green looking splotches, much the way water spots on a ceiling bleed thru a fresh coat of paint.
For more info on dealin' with this problem, check out Wayne's recent painted PT posts thread.
Hope this helps.
