The top coat of external paint on my concrete window sills is peeling.
About 5 years ago we had it painted. The decorator applied what looks like white gloss over the previous coats (which looks like black gloss). Not sure what (or if!) he prepared the surface with.
Over the years the white coat has peeled from time to time.
After I have scraped of the flaking top coat:
1. What is best for preparing the surface?
2. What is the best paint to reapply?
Thanks in advance.
