Capstones on a garden wall were flaking badly, I scraped them back to bare concrete and painted them with 2 coats of masonry paint, no primer or undercoat as advised by paint shop.
There was a heavy dew the evening I painted on the second coat so it may have affected drying but this may not be root of the problem.
Anyway, 3 months on, the paint is peeling / flaking off wholesale.
I think now (despite paint shop advice to the contrary) that I should have primed or sealed the concrete, but I may be wrong.
I was thinking of scraping it back again (shouldnt be too hard at the rate its peeling) and this time sealing with dilute PVA before repainting in properly dry conditions, in spring or whenever that happens...
Does that make sense?
Any better ideas?
