Haven't painted anything for 15 years, last few times we had a builder to do it. Now need to get white and not shiny paint for the kitchen, and also the bathroom ceiling. Kitchen is very dry, no issues with moisture etc. Bathroom ceiling we have constant mould problems - actually we have repainted it with a mould reducing paint but still comes through every now and again. Can't I just get a tin of white K&B paint to do both or do I need 2 different types? A rare foray into B&Q didn't help, only a couple of types of K&B paint all seemed very shiny and v. expensive. Google throwing up conflicting advice and thousands of options of white paint. Sort me out MN painters.
