Hi, I have a utility room which in the past was un-heated
and also had little ventilation. The previous occupants did their
drying in there (one of those ceiling things) as well as washing etc.

This caused a decent amount of mould on the rather fantastic
swirly patterned plaster ( a job for future rectification ).
Having added heating and adequate ventilation I would like to
paint the walls with something resistant to mould.

There will still be a washing machine and vented tumble-dryer
in use so I expect a certain amount of air moisture etc. Would
I be best off using an exterior water based masonry paint or is
there a suitable mould/damp resistant interior paint on the market?

T.I.A for any advice.
