I will be ordering some timber from my local timber yard to make a
Thinking 2x4 nominal PAR tanalised timber. Now the treated timber
(sawn) at the depots is a horrible green. But is that tanalised or
just weather treated?
I want to stain and varnish this bench so don't want the green stuff!
It might be worth looking a bit further. I found that most of the DIY
stores had timber that was simply dipped in green preservative (not
pressure treated) - but they didn't claim it either - I forget what
the weasel words were. Timber yards had pressure treated, but again
Eventually I found a choice of green and brown pressure treated timber
at a fencing company with their own saw mill who are also
manufacturing fencing rather than just stocking. They have their own
pressure treating plant and were doing both colours - the brown being
a little more than the green.
You can stain on top of green as long as the brown is a fairly dark
one. Paler colours will tend to look rather muddy.
To email, substitute .nospam with .gl
The Brown/Green often depends upon what it is treated with.
Brown is better for soil contact (always damp), green is best for dry areas.
The dampness of the wood effect what will attack it.
You can find in depth anaylsis of the different treatments if you search google.
I have had to order it PAR, the timber yard have to place an order for
the PAR as they only stock sawn. Have confirmed it will come in Green
:( so will have to try some dark stains on it!
At least if I make the bench and it falls to bits after the first
season it was me that did it and not BandQ :) can't blame anyone then.
I'd have thought if it has to be ordered, you could have asked for clear
pressure treated stuff. I *think* tanalised is green purely for easy
identification, and checking how far the treatment has penetrated.

The only time I bought tanalised timber it was a *light* brown colour -
about as dark as pine goes after being exposed to sunlight for a couple
of years. I painted it with white microporous paint and it covered with
Maybe someone can confirm this but I thought that Tanalising was a
specific process, maybe even a trademark, and therefore not all pressure
treated timber is *tanalised*, it could just be Cuprinol green wood
preservative or similar applied in a pressure vessel.
Oh, and when Tommy Walsh uses tanalised timer on Ground Force it never
Depends on the stain, it may cover it.
Note that tanalised timber contains poison (arsenic I think), I wouldn't
want to make a picnic bench out of it.

I found the best effect was to allow the timber to weather for a couple
of years, then clean with a pressure washer. You may be able to get some
weathered timber from the yard.
Copper, Chrome and Arsenic.
There'll be a mad woman in any minute now to rant on and on about it.
FWIW when cutting any preserved timber or indeed any timber, wear a dust
mask. Don't use the sawdust or shavings for pet bedding.
Personally I don't worry about the arsenic content of treated timber,
worrying about the name is stupid. All beer contains arsenic - does that
worry you unduly?

Could be both, the green is just dye to indicate it's been treated.
Then you prolly don't want tanalised, the chemicals can mess up
varnish and stain to an alarming degree. Staining and varnishing
tanalised wood is two belts and braces, better to stick to normal PAR
(cold grown softwood if you can't get hardwood)

Genuinely tanalised timber is always green. Some other treatments can
be brown; both solvent based and stink a bit.
What you need is protimised timber; this doesn't have a colour and
will take any finish. Just had my 14x5 purlins done like this.
