Best treatment for timbers

Reggie.

Hi all. Putting up a kind of gazebo and wondering what's the best way to treat timbers. Put creosote on timber before and it seemed to wash off after a while so not too impressed with it. Is there anything else you could use?

A nice balance between long lasting and not too expensive

Buy pressure treated timber, it'll be more expensive initially but imo cheaper in the long run as it'll last longer. Touch up cuts/holes multiple times with a preserver before assembly.

If you've already got the timber then treat it with multiple coats of preserver. End grain is most vulnerable so it would help if you soaked ends of timbers in a tub of preserver overnight or longer to allow deeper penetration. Do this after you've cut your timbers or made joints. Paint on preservative doesn't penetrate deeply even with a few coats.

Yeah ill be doing that. Just a normal treatment will do the job afterwards for colour would it

Would be the best option,
It's not thst much more expensive 10c a board.
Depending where you are Larry Byrne saw mill in glenealy co.Wicklow are by far the cheapest

Personally I'd give it a few coats with a good penetrating wood preservative first before a coloured treatment. You can get it in clear so that it won't affect the finished colour but it's not so easy to see where you've treated.

Would you do that even if the wood was pretreated

As above, buy pressure impregnated timber (green stuff).

Then use Protim for anything that is above the damp proof course and not in direct contact with the ground. Other types are available like creocote(creosote alternative)

Again. as above its imperative you pay attention the end grains

Sorry somehow missed you plan on going for pressure treated. In that case I wouldn't bother with clear preserver as it can't penetrate any better, though I would still treat cuts in case the factory treatment doesn't get to the core.

Really just looking for something to give it a good look. Ronseal or something maybe.
