Hi everyone Im noob with all painting stuff that's why i need your help. I think i chosen right paint for my wall and ceiling, which will be JOHNSTONES TRADE ACRYLIC EGGSHELL BRILLIANT WHITE and Magnolia my flat is 54m2 i think i will buy 10l of magnolia and 5l of white just tell me if that's not enough. I'm going to paint on old paint. but now i don't know what accessories i need to do this in the right way to protect everything and go through the painting. For now i know i need microfibre roller 3/8 inch and tray, stick some protecting foil, and which tape? I read some tutorials but i'm still confused, maybe someone could send me a list of links with everything i need to buy on amazon or any other stores which don't charge that much for shipping i chosen johnstones because is not that expensive 5l cost 30-35gbp Thanks
