Best Wood Preserver Product For New Built Shed

[Thunderchild]

I'm building my dad a new shed from scratch, so all wood will need treating. What is the best thing to use ? it needs to be good but without going stupid on price as i have 170 sqm to cover.

[Dizmo]

I've known people to use Wickes own brand wood stain for painting exterior wood. I've never used it myself however if I was going to be covering 170 m2 I'd probably use a stores own brand. You'd be looking at spending about £20 per 50 m2 with a good quality stain. However you're going to need at least 2 maybe even 3 coats. Or is the 170m2 taking into consideration the coats?

Whatever Katie Price uses looks like it's long lasting !

[ummmm]

Thunderchild....have you got a local independent hardware store?

I find them to be very helpful. They actually train their staff...

Thunderchild Can you use pretreated Timber if you you are buying new? Really then it is a case of deciding on colour you want. 5L of water based will cover around 30m2 one coat, so that's around 30L per coat, would search the net and buy in the largest container size you can (within reason)

Who's Katie Price ?

It's 170 m2 for each coat, so yes 340 m2 total. Yes wood is alegedly pretreated but I've had pretreated fence posts before and still soaked 2 coats of cuprinol into them with ease.

I don't want to simply colour the wood, I want to make sure it lasts as places like the underside of the floor and joists can only be painted the once. I could consider something tougher on the floor and something cheaper on the walls as they can be redone as often as required.

Katie Price aka Jordan the glamour model.

oh yea, I've seen that advert on youtube, him and his "deck"

If it's tanalised properly it will last you just need to know / trust your supplier -- would not purchase your timber from one of the DIY stores. Agree about joists / floor so maybe split it into two types of treatment and specify as such. Also build so that there is good airflow underneath floor and put some DPC membrane between joists and ground and just put the joists raised from your sub base Not directly on ground.

What size you building W x D?

[Thunderchild]

I bought the wood from yourk timber products, they make sheds and supply the wood too, very good prices but a nightmare to get it all sorted right. Timber from DIY stores ? no way they would have cost 3-5 times as much. I'm not sure if it was tanelised in the end but my limited experience is that it will take more preservative and does not look that well protected to me.

Tonyv it's 10'x12' and nearly 6' tall

[TonyV]

And how thick is your flooring going to be and what construction T&G or sheet?

[Thunderchild]

it's T&G floor on 40x40 joists, we will stand them on bricks to make sure they don't sit on damp concrete

[Thunderchild]

flooring is 19mm thick (assuming they get it right)

[The Builder]

Proper, vacuum-impregnated tanalised timber from a builders merchants would normally see us out, Thunders.

Any further treatment would add to that of course, but mainly for colouring.
This is good... just add water (it;s concentrated).
