Hi,
I have recently been scrapping off the paint in a downstairs room. The paint wasn't particularly bad but there was a little bit of flaking and crazy-paving affect and a small number of hairline cracks so I decided rather than paint over to go back to plaster. (The paint was no worse on external or internal walls)
Last night was very wet and windy and now I have noticed 4 small circles in the plaster that are clearly damp due to a dark colour. They are between about 1.5 and 2 meters off the floor and between 4 and 8 cm in diameter. They are all on the wind facing side of the house, external wall.
The room is not heated much - about 16C and 60% relative humidity.
Obviously the damp patches will soon dry but can I assume this is something that needs immediate attention? The wall is 1980's Brick and Block and the cavity filled a few years ago. The external wall (just on that side) the mortar has taken the affect of the weather although I'm not sure if it requires repointing just yet. It is a gable end so there is no gutter. The roof verge (correct term?) is just concrete. (not wood like some houses) I have noticed what looks like there might be a small crack in the plaster near the very top of the roof.
Any thoughts on likely cause? I assume it is more than just needing the heating on higher?
Thanks.
