How to Seal Granite Floor Tiles
- 1). Sweep the floor thoroughly to remove any dirt or debris resting on the surface. Spray granite cleaner on the tiles once surface dirt has been removed, and mop with a clean sponge attachment to remove any spills or other substances from the tiles. Allow the floor to dry completely.
- 2). Pour a silicone-based, impregnating sealer onto the floor. Use a mop with a new sponge attachment to spread the sealer over the floor. Saturate the tiles in sealer so that the granite appears wet; look for and cover dry spots to ensure you cover the entire floor. Wait 10 minutes for the sealer to soak into the stone.
- 3). Dry the granite with absorbent, cotton cloths to remove excess sealer that has not been absorbed. Buff in a circular motion until the stone is dry. Change cloths whenever the cotton stops absorbing sealer to ensure an even finish on the floor.
