If you want to keep your tiled areas looking their best for longer, then yes, tile and grout sealer is a must-have for your home! Natural stone, unglazed tiles and grout are naturally porous, which means they will absorb any liquids, dirt and moisture layering the surface, staining and damaging them as they go.
Not only do tile and grout sealers enhance the longevity of your tiled spaces, they also help to reduce the amount of cleaning necessary by creating a protective barrier that is largely resistant to dirt and general wear and tear. As a result, sealer can actually help you save money on a tile and grout cleaner in the future.
