Hello, I have been doing some research on this and I've got some mixed reviews. I've seen someone people recommend stain because it allows the brick to breathe but I haven't been too impressed with the color saturation of the brick with a stain. I've also seen people go with a masonry primer and then use a regular latex paint over the primer. I want to paint my brick fireplace a grey color and repaint the brass door/trim black. What are your thoughts on which route I should take? Also I don't mind using a brush to clean up the brick along with some TSP to clean the surface to get the best adherence possible.
