DIY - depending how much tile/grout/granite, you have. Did my old place and took my wife about 5 hours each day to do the whole house (2 coats), never had any mildew or mold in any areas with Miracle 511.

Soon to move into a new build. Does anyone know why the builder doesn't seal the grout for you?
Is this easy to do on your own? It it time consuming?
