Hi.
about 4 years ago I painted our old pebbledashed house with an oil based exterior paint that was recommended to me by the paint company. I followed the instructions to the T by thinning the first coat then applying the second.
Last year we had a big problem for the first time with condensation. (there are no trickle vents anywhere) This year we are having a major problem with condensation. I have almost got it under control with opening windows as I guess that the house needs to breathe. What I need is info about what size vents are needed per room size.
Also water is running down the wall where there is no condensation.
The water running down the wall I am guessing is ice that is melting but cannot think how it is getting through, under or over the exterior wall (single skin) unless it is coming in from the roof.
But ice is obviously water and I cannot think how it can get into the roof as water to freeze then melt!!
This is slowly destroying our property and any help or suggestions gratefully appreciated.
Thanks in advance.
John
