How to Apply and Seal Grout on Tile Floors

By: Danny Lipford

The last step in laying a tile floor is applying and sealing the grout. After the tile adhesive has set, apply grout to the joints using a rubber float. Grout comes in a variety of colors, but darker grout tends to show less stains. Stainproof grout is also available, though it isn’t as easy to work with as regular grout.

Once the grout has dried, apply a grout sealer to the joints to prevent stains from occurring. If grout is stained already, use a grout stain pen to make the grout a uniform color.

    The grout on my bathroom tile is cracking and coming up. I don’t believe it was sealed properly. I would like to get this re-grouted but don’t know if I can get someone to do it and am a little nervous about doing it myself.
