Recently had new room plastered. been left to to dry for 2-3 weeks - plaster pink and ready to be painted.
Did mist coat this weekend - and overnight noticed these random yellow/dull stains in random parts of the walls/celin. its in about 3 or 4 places overall in small patches.
The photos dont show its yellowness very well - but what could/would this be?
there is also no pipes nearby as suspected water issue but nope.
Any insight into what it may be - and maybe how to resolve? i keep reading about Stainblock - so likely head down this route but ideally like to know whats causing issue.
thanks
