Bought a 100 yr old house few months ago. Don't know anything about diy, which will become obvious as I don't know what the bit is called - skirting board on the staircase? Anyway has been freshly painted by previous owner but looks awful, bashes and cracks showing through etc. Ds knocked a picture off the wall and it bounced down the aforementioned skirting bit.
So I picked a bit. Then I went and got a butter knife... 
And now I've got some huge holes in the white paint with dark green and a tiny bit of wood showing through. How many million hours work will it be to clean up and how do I know if the wood is nice enough to be naked?
