We painted our old pine floorboards white last autumn (1 coat primer, 2 coats b&q 'trade' floor paint) and it's already looking awful especially in high traffic areas or where chairs etc are moved frequently. It's a bugger of a job as it means moving out of the room (kitchen/diner ) for best part of a week so we're going to get someone in to do it whilst we're away but really want it to last more than 6 months this time. Any recommendations or brands to avoid?
I used rust-oleum chalk paint too and it was dreadful, I found it marked very easily. After lots of research I used Little Greene paint co as their floor paint is oil based unlike F&B. It's perfect, lots of colour choice and only took 2 coats (one 2.5 litre tin for a 14ft x 14ft bedroom) and hasn't chipped at all. Would highly recommend it.
