Before sealing granite, make sure you clean the surface well with a granite cleaner. Next, spray the granite sealer on the surface in a three-foot section and immediately buff into the stone with a clean lint-free cloth. Repeat this process two or three times, allowing the sealer to cure for 24 hours.

Does granite floor tile need to be sealed?

If your tile is stone (slate, marble, granite, travertine, etc.) then it will need to be sealed. Stone is naturally porous and will absorb spills and stain fairly easily.

Can you use tile sealer on granite?

Solvent-based sealants are a little heavier duty and work better with polished granite countertops and floor tiles. For the best results, look for sealants with fluorocarbon aliphatic resin as the active ingredient.

How do you protect a granite floor?

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.

How do you clean granite tile before sealing?

Clean the countertop 24 hours before sealing, making sure to avoid potentially damaging vinegar, lemon juice, baking soda, bleach, or harsh commercial cleansers. First, take everything off the counter and wipe it down well with a clean, dry microfiber cloth to remove all surface dust.

Can I use grout and tile sealer on granite?

Use a granite sealer that is safe to apply to stone surfaces, such as Granite Gold Sealer®. Spray right in between tiles and make sure all grout is covered. You don’t want to let the sealant dry, so you should wipe it into the grout lines right after spraying.

How do you know when granite needs to be resealed?

If the granite surface immediately takes in most of the water and develops a dark mark or ring, you need to seal it once every few months. If it takes a few minutes for your stone countertop to soak up all the water, you only need to seal it once every year or two.
