purchased 6X6 pressure treated (Georgia/Pacific) 12 foot pine studs
needed only 9 foot studs so I sawed off 3 feet to discover that
only penetrated from 1/4 inch to 2 inches (depending on location).
Is this normal?
What are the expectations? If this is normal I don't want to press
This is second time this has happened (last time 2 years ago). Last
time GP would do nothing about it, but Lowes made adequate
compensation to me albeit it was G/P's fault.
That is normal. Until you get up into the "salt water treated" levels
the treating is skin deep. Most stuff in the "home" type stores is
minimally treated. You need to go to a marine supplier to get the real
stuff. That is usually overkill for any above ground use though. Just
be sure to put the uncut end down.
There is a treatment you can purchuase at most home centers and coat the cut
end of a pressure treated stud or any PT wood, wish I could recall the name,
but its a brush on or you can dip the end in a bucket of the stuff, down
here it can be found in Sutherlands, dont know of the other big box stores
I would presume the use of the word "studs", but that they were 6x6's
pretty much negates that...
I agree there's no indication whatsoever of what the OP is actually
using them for; likely would be for deck support or similar but guess
could have a need for a center beam support column in a basement where
would like the PT on a concrete pad.
My curiousity was why if only needed a 9-footer would buy 12's instead
of 10's given what a 6x6 must be these days... :)

Because he'll get one free 9-footer for every three 12-footers he
buys. Do the math. ;-)
In Florida it is code for the bottom plates on monoslab walls, window
bucks and in some cases, furring.
Moisture and bugs are the issue.
I think there are some membrane solutions too but PT is usually an
Back in the CCA days they rated PT lumber by the number of pounds of
CCA you put in a cubic foot of lumber. This ranged fron 0.25 CCA for
that green washed crap you got at the Home Depot up to 2.65 CCA for
heavy duty marine construction. 0.40 was about the practical minimum
for anything that will get wet and you want to be around a while.
Now they are using a more environmentally friendly poison but the
pounds per square foot rating is the same idea. I am just not sure
what a good borate number is.

These are ACQ .. not borate. The number on the tag is .40. Looked
that number up on great URL given in a previous post and it is ok for
my usage, but IMO the penetration of the preservative was not
satisfactory. Lowe's agreed and gave me adequate compensation.
The pressure-treatment only penetrates an inch or so, depending on the
process. I'm not surprised many companies have taken cost-cutting
measures. You could dip or paint the untreated or cut areas with
creosote or other product (as recommended by a Lowe's employee--who
knows you might get a second compensation if you are tactful).
Creosote oil/coal tar, since 2004 or before, is a restricted use
pesticide due to possible oncogenic & mutagenic effects. It is not
available to the general public. However copper naphanate is
available at many hardware stores and does a reasonable job.
