after a bit of advice/reassurance on how to deal with this flaky paint at the base of a customer’s house.
Looking at it, the render goes right down to the ground so sucks up moisture from leaves and excess rain that gets behind the paint and causes it to fail. Rubbing the render with a finger leaves some residue, but it’s not what I’d call “dusty”. The house was apparently redecorated five years ago, though my gut feeling says it may have been longer than that.
Normally I would say go in with a scraper and take off any loose that comes off easily (but obviously don’t go too mad), let it dry off, maybe touch in with Dulux Stabilising Primer then two coats of Dulux Masonry on top.
It may well be that advice to the customer is keep leaves cleared regularly from that channel, but that ultimately it will always get wet and this will recur eventually. Would that be right, or am I being too negative?
There are other areas of flakiness higher up the building, and I’m guessing I’d treat them the same way.
Any product or process advice very welcome, thanks.
