Hey all, I'm new here but have an issue with a clients garden where the existing painted render was painted over and now both layers are just peeling off like crazy. It was painted against advice at the wrong time of year, but even so the peeling is super dramatic! This hasn't happened before and other bits of painted render in the garden (one much newer, one much older are fine)- it's just this area. The tops of these walls are also rendered and did have some damage but I'm wondering why the original paint was staying on and the new has had this effect? Other than recommending coping, removing as much as possible to dry and repaint- I'm not sure what else to do- if the wall is being soaked from behind (from raised beds) then will it just happen again? Or is there some kind of sealant we can put a layer of on first before repainting? Help!
