Diluted white emulsion paint (City Centre NR1)

I have about a third or half of a 10L container of diluted white emulsion paint. I used it as a 'mist-coat' on a newly-plastered room - worked a treat. There's enough left to do a decent-sized wall, or perhaps a small room. I got it from a fellow freegler, and would like to pass it on. Any takers?
