Painting masonry is not for the casual painter. If painting is prep, even more so for painting brick and block surfaces. And specialized product, you’re gonna need the right stuff.
Wire brushing is a good start. Then a shop vac and a degreaser. Don’t forget drop cloth and masking tape, which is not easy to do along the uneven edges.
Prime with Sherwin-Williams’ Loxon Concrete & Masonry Primer starting with a brush in the mortar lines. A roller is probably the best tool for the surface. Finish with ProClassic Waterborne Interior Acrylic Enamel of your color choice.
