HELP! I started out with a traditional greenish 4-coat VP but it was the wrong color when all was said and done - so I decided to use a white casein paint over it to tone it down. It was still too yellow (needed colder blue) so I kept adding layers of the casein with linseed, and at some point added non-pigmented casein size. At this point its flaking and I dont know if its the casein or the lime in the VP or something else. Do I really have to sand it all down and start all over??!! (Sorry this is a dup post; didnt know where to put it.)
Why would you add a white milk paint over a highly alkaline lime product? Why didn't yo ujust do lime over lime?
it is hard to answer a question about such a highly unorthodox method of troubleshooting a green lime VP. (just very curious here)...
If the product is peeling, it is probably due to some incapatability or maybe you burnished the lime to the point taht the paint now needed a primer base for bond or "fill in the blanks".. it is hard to know at this stage since either will cause futhur delamination of the remaining wall conceptually.
If you paint over raw wood and it just ained the day before, you are going to get peel, right? In time? the begining of peeling doesn't mean it ends there because no matter what yo uput on top of it, in time, it all wil lpeel away (going to the extreme)....
(alternatively, you could have used a liquified lime VP as a sort of oveglaze or lime wash but anything you used would ahve changed the look of the original lime.)
