Good morning,
This is my second post regarding painting my house. I had very useful tips on my first set of questions, but thought I should start a new thread with my next question.
I am preparing to paint the south facing external wall, the wall is roughcasted about 5 years ago, and never been painted. The wall is in very good condition apart form the fact it has turned red. I see loads of houses around with the same problem, always the south wall.
I have pressure washed a section to see how easy it is to remove, and thankfully it comes of very easily.
My questions are:-
Why did the wall turn red? is the colour coming out of the wall or is it turning red on the surface with the rain or something?
Can anyone advise what I should be doing, as in, is it OK to just clean the wall and then paint over with paint (first coat 20% water)
Many thanks in advance
JJ
