Tile and Grout Sealing Requires Accurate Assessment of Grout Condition First

Before sealing tile and grout, you really need to assess the grout condition first. If it's cracked, crumbling, or has gaps, sealer won't stick or prevent moisture damage. I always start by cleaning the grout lines, then check for soft spots and missing chunks. Only after that can I decide on the right sealer and prep work needed.
