Yes it's for the house we're building in Scotland. The workshop and pottery studio will have wet under-floor heating so I need a floor that doesn't insulate, is tough, will never need repainting and looks smart. It will need to resist water and the occasional spillage of solvents like paraffin, petrol, whatever and can be brushed and washed.
We haven't given it much thought except that the walls will be lined with fake T&G planking in MDF for a traditional workshop look and better hanging of stuff like shelves than plasterboard. An engineered wood floor would be nice but would soon get damaged.
I'm wondering if the finish can be painted straight onto the screed or something else is needed. How tough is self-levelling screed?
