There is another thread on this topic but it's 4 years old. My house is very dark inside and gets hardly any natural light. I've been told this is something that causes white gloss paint to 'yellow'. However I can't re-paint all my doors and frames once a year (that's how long it's taken for my pure brilliant white gloss dulux trade paint to turn yellow). I've heard there are some white gloss paints that dont' yellow, one being Dulux Trade Aquatech. But some people say it's a bitch to get on and off and dries too quickly and simply isn't as good as normal oil based gloss paints. Can anyone tell me what the deal is? I want some tough, hard-wearing trade brilliant white gloss that won't yellow. Is Aquatech any good? Any others?
