As I started to strip paint with my pressure washer the other day. I noticed that under the paint, I seem to have two skim coat layers on the block; at least the white stuff in the picture feels abrasive like mortar and it crumbles like a masonry product. Is stripping the paint alone sufficient to achieve an acceptable bond? Should I try to strip away the white stuff before I apply the cultured stone veneer? Should I try to strip away both layers of mortar to expose the concrete block?

This isn't surface bonded block. That thin layer of white mortar stuff only came off when I used a 3500 PSI 4 GPM pressure washer with the nozzle pressed right up to the surface. I'm thinking all I'll need to do is remove the paint and adhere the veneer directly to the white stuff (no lath).
