This question has been asked before but most posts seems to be from several years back. Had some building work done and aiming to repaint most of the house over the coming year, I usually buy Dulux Trade paint and have done so for years. This is because even though it’s more expensive in my experience it does the job in 2 coats without fail and I’d rather that than risk having issues with an inferior paint. However, having just bought 10 litres of white vinyl Matt for £50 I’m wondering if there’s a cheaper alternative that might do an adequate job? I want to paint white onto skimmed (mist coated) plaster and walls/ceiling that are already painted white or magnolia.
