Sealing Grout in Tile Floors

Flooring, Interior, Kitchens and Baths, Video by Danny Lipford

While ceramic tile is a durable, low maintenance material, the grout between the tiles is not. Unless stain-proof grout was used, the grout will need to be sealed. Allow the grout in new floors to cure for 30 days before sealing.

If the grout is stained or dirty, use a mild breach solution and scrub brush to clean it, then allow the floor to dry completely before sealing. If the sealer doesn’t come with an applicator, buy a separate applicator bottle with interchangeable tips. If the grout has become stained and won’t come clean, use a special grout stain pen that both stains and seals it at the same time.

    How often should one seal tile? Can sealer be applied over year old sealer?

    I would like to know how to lay down ceramic tile from the beginning. My husband and I are building a house and want to put tile in our bathrooms.

    Thanks

    The grout between the tiles on my kitchen counter is coming out and it needs to be redone. Is it necessary to remove all the old grout or can new grout be put over the old?

    We just got a granite tile countertop in our kitchen. I don’t think they used a stain-proof grout. What is the best stuff to seal this kind of grout? Is it the same as floor tile grout and do you follow the same rules as for floor tile grout?
    Thanks.

    We have ceramic tile on the walls and a one piece floor in the shower. How do I seal between the tile and floor piece, should we just use the grout or a heavier water proof sealant? I am having problems with the water seeping past the door and ruining the wall outside the shower. I am in the process of removing the sealant right now and letting it dry out. Nancy
