Regal Select Matt

Hi Guys. Having a nightmare with this at the moment, it's flashing like a bitch!! I'm working in a very large bungalow doing the entrance which is very big. The lighting is very critical and lots of down lights on the ceiling, even after 3/4 coats it looks shite!

Anybody else had flashing with Regal? Really disappointed as it's made me look a bit of a twat

Edit... Well I got a 30quid tip so only in my head it's made me look a t$#@
