Palmer Brothers Painting

As an owner at Lafayette Park Condominium for many years, I have had the recent unfortunate experience of seeing what Palmer Brothers does when does a major painting project.
Our condominium complex, of eight 6-​story buildings, with 400 units, hired Palmer Brothers last year or the year before to redo the 48 hallways in these buildings, including installing crown moulding around all the unit doors and elevators, and removing the wallpaper from the hallways, refinishing the surfaces, and painting them.
Part of the project included painting over the «flesh-​colored» (my description) unit doors into the hallways, and the elevator doors and frameworks, with a sort of dark purple/​black paint.
Unfortunately, Palmer Brothers did not prepare the painting surfaces correctly. So when someone would bump furniture or a shopping cart into the painted surface, with even the slightest touch, not just small chips but small sheets of paint would come right off! You could see clearly the flesh-​colored paint below.
No attempt was made to (1) sand the old paint surfaces or (2) prime the old paint surfaces. So the slightest disturbance to the new paint made it come right off!
Other aspects of their performance I found greatly troubling, but their inability to properly prepare painting surfaces I found to be extremely poor.
Awarding the company two stars was generous.
