Farrow and Ball dark color isn't covering well
We had a coat of dark primer and two coats of FB Railings on new drywall. It doesn't look great. The painter wants to add the same color in a shinier finish on top to mask the patchiness. He did this in our basement with a navy and it didn't help. One wall has 3 coats of the paint and still looks bad. What can we do? The photo doesn't illustrate the patchiness, but you might get the idea.
