Preservative for shed base (underside)???

[purplekat]

Hi,
Building a new wooden shed and instructions say to treat the underside of the base with a good wood preservative - obviously the base is only going to be done once and ideally I need to build it before the weekend rain so I want something faitrly quick drying. I'm using Cuprinol for the outside but what do I use for the base?? (I've only had a concrete shed in the past)

Creocote

I thought that'd be the answer, but I hate the stuff - guess I can cope for this one bit

Bitumen or both with the bitumen last.

If you get the base for the shed right, it will never be in contact with the ground and so it's unlikely that a preservative will be needed. However, if you do decide to apply preservative, Cuprinol should be absolutely fine.

Our new shed is on slabs,with tanalized timber between that and the shed base,the only painting thus far is the outside of the shed it'self,depends on what time and money you want to spend,

The quick and easy answer is pretty much any wood preserve that you have laying around. But as the other posts suggest do not put the base straight onto the ground. Try and raise it using bricks, slabs etc. If you are putting it straight on the ground then a more substantial treatment such as creosote will be needed

what everyone else said. also make sure you give the end-grain a good soaking. especially wood that has been tanalised that is then cut (as that end may not have been treated)

All good advice, but if there is any risk of water wicking up the block / slab put in a layer of plastic / DPM. Best middle of stack so that wood is resting on porous material
