Limewash gives brick a soft, chalky, aged look, but it can wear off in rain or rub off indoors. The best brick sealer for limewashed brick protects that finish while staying breathable, because limewash itself works by letting the wall breathe.
Many limewash brands advise against sealing, or only allow specific products. Always check your limewash maker’s guidance and test on a small area, since sealers can darken or change the chalky texture.
