How to Grout Tile
Learning how to grout tile is not that difficult and once you know how you will have the skill for a lifetime. From countertops to showers, grouting tile by yourself can save you a lot of money. The method is the same no matter what type of grouting you will be doing.
And, it is not rocket science, nearly anyone can do it.
Choose the Right Grout
There are two basic types of grout that you will choose from. Which you choose will most likely depend on the width of the joints in your tiles.
Sanded grout has sand added to it. The sand adds strength when grouting the wide joints that are often used with the larger tiles on floors particularly.
Unsanded grout is for smaller joints. You might find these smaller tiles and smaller joint areas on countertops, backsplashes or bath surrounds.
Next you will want to choose a color. There is no rule of thumb to choosing the grout color for tile, you should choose what you like and what looks best with your project. Here is a crash course in color theory that may help you make that difficult choice:
White and light colors will help hide the mistakes you may have made in setting the tiles. They will also highlight the color in the tile making it seem more intense. On the down side, light colors show dirt very easily. Don't use white grout on a kitchen or mudroom floor!
Gray can seem boring but it goes with everything and it doesn't show dirt easily. It will not show up your mistakes the way that the dark colors will. On the other hand it will not look as dramatic.
If you are very bold use a dark grout with a bright or light tile to highlight the pattern and add drama and excitement.

Grouting Tile the Easy Way
The mortar on your project should be allowed to dry thoroughly before you begin grouting. Follow the directions on the mortar as well as on the grouting packages for best results.
- Clean the surface of the tile completely. Be sure to remove the entire amount of residue on the mortar as well as any dirt that may have gotten on it.
- Run a bead of mildew resistant caulk around the perimeter. This will help to stabilize your project.
- Preseal unglazed tiles to keep the grout from getting into the pores. Grout in the pores of tiles made from slate, marble, or clay can cause haziness to permanently mar the look of the tiles.
- Now you are ready to mix the grout. Stir it, following manufacturer's directions, until it has a consistency like paste and is free of lumps.
- Always start in the corner of the room furthest from the door. Plop a glob of grout down. Hold the float at a slight angle and firmly, but gently, push the grout into the tile joints.
- Work with a small square of floor at a time. As you grout use a clean float to remove any excess from the floor. Wait ten to fifteen minutes for the grout to set (or follow manufacturer's directions) and then wipe the floor with a damp cloth.
- Mortar may build up in corners or in baseboards. There is a tool called a margin trough that makes it easy to remove this excess mortar.
- Carefully, using a large, damp sponge wipe the tile toward you. Be gentle so that you do not pull the grout from the joints but be firm enough to get the excess grout off the floor. Continue this process, rinsing the sponge in water as you go. You may need to change the water several times during the process.
- Go over the floor as many times as it takes to remove the grout from the tiles. Always be careful around the joints.
If your project is a floor allow it to set for a full 24 hours before walking on it. To help the grout set properly mist the joints once a day with water in a spray bottle. Repeat for four days.
Basically you can do this one of two ways. You can seal both the tile and the grout or you can seal just the grout.
If you have put down an unglazed tile in your project then both the tile and the grout will need to be sealed. On the other hand, if you used glazed ceramic tile then you only need to seal the grout in the joints.
Sealing the grout allows it to resist water, staining, and mildew. It will help it stay looking new and ultimately be easier to clean. Always wait several weeks before sealing the grout. Apply the grout sealer of your choice to the joints according to manufacturer's directions. Quickly wipe off any sealer that might get on the glazed tile.
