Grout Guide: Should I Seal My Grout?
Sealing your tile grout provides a layer of protection against spills, stains and water penetration into your grout joints. Using a clear liquid quality grout sealer should be last step in your grout removal / grout repair project. For little cost and effort it is well worth saving the beauty and integrity of your grout job.
New grout requires a curing time of 72 hours before applying a sealer to ensure proper bonding. After sealing, foot traffic can resume after about 4 hours and the sealer will fully cure in approximately 24 to 48 hours.
When sealing your grout, apply the sealer liberally, but avoid puddling. Follow the application instructions for wiping time and if there is recommendation for a second coat. It is not uncommon for some grouts to become a shade or two darker when sealed.
