Dulux Paints 5 Litre Light And Space Matt Absolute White

Now I have used this paint in the past with no issues - I don't know if the paint I brought (Paint LTD) on here had been stored too long or was off but it has been awful!It has ended up grey - and may I state it was being painted onto white walls so no issue with others colours. I have ended up having to have the decorator get another brand to paint with - after two tins of this stuff it still wasn't white!I can't say whether it is a company problem or a case of bad/old stock but even the fumes were awful - I have never smelt paint so bad!!! Disappointed - will not be buying again!
