Grout is porous by nature, which means it can absorb liquids and stains. Without proper sealing, your grout lines can become discolored, stained, or even damaged over time. Sealing your grout provides a barrier that prevents moisture, dirt, and other contaminants from penetrating the surface. This helps maintain the cleanliness and longevity of your tile installation.

Ideally, you should seal your grout as soon as it's cured, typically 72 hours after installation. However, if your tiles are already laid and the grout is looking a bit worse for wear, it's not too late. You can still seal it to protect it from further damage. It's also a good idea to reseal your grout every 2-3 years, depending on the type of sealant used and the amount of traffic the area receives.
