Walls of one room covered in tiny little spot marks
I live in a timber framed bungalow. The main bedroom has a very small ensuite shower room. The walls are painted and if you look carefully each one is covered with tiny little spot marks, a bit how water would look if fine droplets had been sprayed, then dried. The walls do not feel damp.
When I first moved in 8 years ago the bedroom smelt a bit damp. For the past couple of years I've not used the shower and I've not really noticed the room itself smelling, but one of the two inbuilt wardrobes still smells when opened. No washing is ever dried in the bedroom and the trickle vents are open all the time. None of the other rooms have this problem and none of them feel cold, other than the bedroom.
What are all these little dots and, more importantly, what should I do about them? Thanks.

Sounds like you are experiencing moisture levels that could be allowing the formation of spores.
Without seeing the room is difficult to totally diagnose but sounds very much like a condensation problem.
If a room is cold enough it would be very likely to be prone to this without the added moisture of a wet room.
Try bleach on the wall and see how that works along with ventilation now that it's a warmer climate.
Look into getting a survey and some action before winter returns.

通风很好当任何mosture present, But this needs to be balanced with heat.. The customer does not say If the room has a heater?, But a good balance of ventilation and heat will solve most problems , Leave a window open just a small gap will do during the day and put heating on in the evening. When using the shower always try to ventilate the room via a small opening in window..

The spots do appear as though they maybe germination of mould(s).
As answered previously this may be due to an issue with regard to ventilation, although this could also be caused by insufficient insulation and/or heating. It would be advisable to instruct a damp surveyor to carry out a survey to rule out anything more serious. In the meantime wash down the affected area with an approved biocide and following this the application of a good quality paint containing active fungicide. To note, approved contractors can usually access mould treatment materials which are far superior to those available to the public.
We hope this helps, and don't worry, it can be fixed.
