I'm painting my shed & have found 1 of the 6 supports that the shed sits on (on top of the concrete base) is rotten. I've managed to get the timber out & have got a new piece to replace it with. I couldn't get treated timber so I've treated it myself (with Cuprinol 5 Star Wood Treatment).
I'm wondering if I should paint it with anything else to get it to last (it'll be pretty inaccessible once fitted). I've got Dulux Weathershield gloss & emulsion, Cuprinol water based garden paint (which I'll be painting the rest of the shed with), teak oil or even just Weathershield preservative primer - or I could go out & buy creasote.
It's pretty much invisible so the aesthetics won't matter - I just want it to last.
Thanks,
Michael
