We have just had the outside of our house painted with Sandtex smooth white masonary paint.
The render looks fine but the stonework around the windows is showing signs of discolouration (yellow). We had problems in the past with these areas of stone so the paint was stripped right back to the bare stonework prior to repainting.
The decorator says he has applied five coats of masonary paint to these areas but there is still s faint trace of discolouration in certain parts, he has said it is due to painting onto the bare sandstone and if we consider it a problem he will return and recoat it again.
Just wondered how many coats the experts on here would consider necessary to completely cover bare sandstone?
