Hi,
Can anyone help. We live in a 2 bedroom cottage that we have been decorating over the last 6 months. The problem I have is that I have red marks appearing on all of of the newly painted walls and ceilings. they dont appear straight away but are multiplying. I've attached some examples and they are all pretty similar in terms of shape and size. they almost look like crayon marks but we dont have any crayons !
thanks
Jaye
