Bonding stucco on parging

This is a masonry wall with a parge coat completed 3 years ago. It was painted with Behr masonry paint 1 year ago. We now are going to stucco. The contractor will use wire lath, but I read what you wrote and I want to give the stucco the best chance to succeed.

Do you think I got enough off ?

Scraping most of the loose paint off is fine.

I am glad someone is using my chipping method. It is important to use a chemical bonder in the scratch coat to ensure a permanent bond.

Here it is again if you haven't seen the chipping and bonding method:
