Ok. The wood painting went well yesterday (thanks for the advice!).
But.... A while ago I painted the downstairs toilet in dulux matt in a dark colour, which shows every splash of water.
I went to the builders merchant and they told me egg shell was what I should have used. Like an idiot I said fine, mix me up a can. So I painted that yesterday. Lord what a disaster ! I think it's meant for wood and metal, not walls. And being oil based (which I didn't realise - more fool me) I've got a load of brushes and a roller to clean up.
Should I leave it a week and see if the shine goes off ?
Can I paint over with a water based product ? On the dulux page it looks like soft sheen is recommended for bathrooms so I've no idea why the paint centre at the merchants didn't recommend that ?
