Painted brick raises a common question: do you need a sealer over the paint? Usually not, because a good masonry paint already protects the surface. The best brick sealer for painted brick depends on whether you are sealing before painting, protecting interior paint from rub-off or dealing with moisture.
We explain when a clear coat helps (interior wear) and when it hurts (exterior moisture trapping), and compare products for each case.
