My painter wants to use Sherwin Williams (because her family sells it at the hardware store). I was going to suggest Benjamin Moore when it was suggested to me that I use either Pratt and Lambert or Muralo. I'm confused.

Plaster walls in good shape. I do have some problem area in the ceilings but it's peeling paint and covering an old water stain.

How do you know which brand to use that will give lasting coverage and maintain its vibrancy?

Thanks,

Ginny
