Shiplap on an outside wall

[seanoge]

I have sealed and painted this wall but the damp come through fro the inside. as you see it is unsightly. Thinking uf using 12/15mm x 150mm Shiplap. Should I fix it directly to the wall(plugs & screws) or are there brackests that might help?

First i'd have a try at taking 2 inch of the render off at the bottom all the way along and put a bead on. Then drill some drain holes along the bottom. If inside the bedding area is a solid bottom it needs drainage to stop it staying too wet or put a liner in the flowerbed.

Yes, base is solid but I drilled lots of small holes before I filled it with soil. Probably all blocked now. It would be too much work for me to dig it all out. And I think dceking would look nice. Get a lot of mould on outside walls here(Penzance) no matter what paint we use.

Can Tarmac Toplite blocks be used in a non-load bearing garden wall?

Should be ok Colin.

Did you put gravel or broken brick in before the soil ??

300mm deep concrete base in heavy compacted clay and will only be two blocks high. Will only be boundaries for patio and flower beds. Was just worried about water absorption and the effect of frost in the winter?
