Painting Summerhouse - help

[Mal1874]

Hoping for some guidance.
Recently bought a summerhouse which was dip treated. Once it was built I jumped right in and painted it with 2 coats of Cuprinol garden shades paint.

I’ve not got this terrible feeling that I needed to put a protector onto the wood first before applying the garden shades paint.

We had some horrendous rain last night and noticed there does appear to be water getting in at the tongue and groove joins too. Is this because I didn’t put a protector on first?

Thanks in advance.

I don't think so

"Cuprinol Garden Shades is suitable for any garden structure including summerhouses and log cabins. If it's a bare wood structure, new or old, its probably worth treating it with a wax free wood preservative first to protect the wood from mould, algae and fungi. Allow this to fully dry before painting"

Since the summerhouse is dip treated it already has protection.

And if you used a wood preserver you risked the chance of stopping your garden shades adhering properly.


Unfortunately Single skin garden building will tend to leak a bit at the cladding joints. No wood treatmentbor preserver would stop it.

Many thanks for the quick reply. So I’ve not done anything wrong then. Concerned I’ll have a rotting summerhouse in no time though. Any thoughts on this?

no, dont worry -if the cladding is treated it will be fine for years

anyway, it wont rot if the water runs off -its only wood that stays wet that rots

Are the boards horizontal or vertical?

The ones within a foot of the ground will rot first.

If they are horizontal you can fix them with brass or stainless screws, and swap them for new when you start to see damage.

I prepared a few spares for that purpose when I did mine

And yes, you can drench the bottom few with numerous coats of timber preserver before assembly

They are horizontal. That’s a good idea. Will just replace them when I need to. I think I’ll paint the inside with a preserver.
