Hi, I have a home built in 1956 and the front patio was originally (coloured) coloured concrete. 15 years ago I painted it and then painted again about 7 years ago. I decided to revamp once again but after having tried
hydrochloric acid and a pressure cleaner to remove the existing paint I have found I still have bit of paint flaking off. I've now tried paint stripping gel followed by a pressure clean to remove any remnant of the stripper. I am now looking for a way to resurrect the original finish which at the point looks very chalky. Does anyone have any ideas. Cheers
