Hi all,
I have just applied a mist coat on our hallway celling in our flat using dulux matt thinned down with about 10% water and after about 2hrs just started to notice lite brown patches showing all over the hallway celling which looks like its where its been damp before in the pass. I know the the 2 years we have been in the flat the hallway has never had a leak in the roof so not sure whats caused this. I am now worried they will show if i apply 2 more coats of matt and not sure what to do.
