Dulux Trade Light & Space Diamond Matt

Is that what they paint the starship USS Enterprise with?

LSD!

Yes, put the final coat on last night, its still fully drying but the finish is beautiful, and certain looks bright, not sure I'd do a whole room with it, but good for the ceiling. I'm expecting it to go a little more matt as it dries completely (from the first coat). I found these rollers sleeves ideal for applying it:

Definately yes.

We've done the house with it, using trade brilliant white for the ceilings and shades of Light & Space for everything else.

Makes ya average dim CFL go further :-)

I've just checked the remainders in the shed. The L&S were retail, not trade.

And also a couple of rooms were in cheaper standard matt, as in those rooms I'm either staring at monitors or the back of my eyelids....
