Greenhouse build

Just come back from a local auction where I purchased a "job lot" of pine at a ridiculously cheap price..no one else bid for it..so my cheeky try on the "going twice" call was accepted.

Its untreated and I intend to build a greenhouse with it using polytunnel film..so I'll call it a "Polyhouse".

Question is, how to preserve this timber best? All of the timber will be internal but will obviously be subject to UV, humidity and splashes from the hosepipe/watering can, the base will have dpc to protect from the ground up.

If it can be avoided I don't want to use a paint that will need to be done every year or a stain that will crack or flake off.

Would creosote substitute be ok for this?

Many thanks!

I assume so due to the humidity and watering splashes, if its not needed then I wont do it. What does everyone think?

I would, as the condensation will run down & sit where the timber touches the polythene.

Did you bid a shilling for it Steve?

 

If using creosote substitute I'd use some heavy duty polythene and make a bath to soak the timbers in.

 

I built myself one this year and used wilkos own oak timber stain. I put 3 coats on,but the timber was treated on mine. I considered creosote, but was told that plants don't like it.

I'll reveal how much I paid and how much I got next spring...when I build the Polyhouse and start a topic on it then.

Thanks for all your comments, and keep them coming if you have any other advice.

Looking forward to March the 20th next year Steve sounds like you got a bargain
there, have you considered Cuprinol DucksBack?

Only I done our garden fence with the stuff about 8 years ago, and whilst it has faded in some
places, in others (I guess where the sun doesn't shine so much) its still looking good
And if you look at the fence whilst it raining, the water never seems to stick to it
in fact and just seems to roll off......just like water of a ducks back!
