Grouting tile plays a very important role in a floor tile installation. When grouting floor tiles is done correctly the tile grout will hold the floor tile designs in place and seal the gaps between them. This makes for a watertight surface for whatever type of floor tile designs you may be using.
Once you've completed your floor tile installation make sure to let your thinset set at least 12 hours before grouting floor tiles, or even before walking on your new floor tile designs.
If you are experiencing humid weather, and using a dense tile, such as porcelain floor tiles or slate floor tile for your new floor tile installation, check to see that the exposed thinset is completely dry. The color of the thinset will become lighter as it dries.
Use needle nose pliers to remove your spacers from between your floor tile designs, and be careful not to nick the tiles as you go.
If you're using a very porous tile such as an unglazed ceramic tile, slate tile or limestone tile for your new floor tile installation,
you should seal them before grouting floor tiles rather than before they have been sealed.
Step 1 To Grouting Tile- Mix up a batch of tile grout
When mixing tile grout, you'll need to mix many small batches. You will need to use up each batch of the grout before it dries out, then mix a new batch for grouting floor tiles for the following section. Be sure to wear your safety goggles and respirator while mixing your tile grout.
Fill a 5 gallon bucket with about 2 inches of water. Then gradually add your tile grout to the water, while mixing with your
grout float as you go.
You want your tile grout mixture about the thickness of toothpaste, and free of lumps. Wait about ten minutes and then mix your tile grout again. Add a little more water if necessary, before you begin grouting floor tiles.
Step 2 To Grouting tile - Push tile Grout into the Grout Lines
To begin grouting floor tile use your rubber grout float, to scoop some of your grout onto your tile surface. Hold your grout float nearly flat and push the tile grout into your grout lines.
Use sweeping back and forth strokes, being sure to push your grout float in two or more directions. Stop after grouting floor tiles in an area of about 10 by 10 feet. This way you'll have enough time to wipe away excess tile grout before it sets.
Step 3 To Grouting Tile- Wipe Away Excess Grout
For wiping away excess tile grout, tip your grout float up and use it like a sponge to clear away most of the tile grout from the surface of your tiles.
Move your grout float diagonally across your tiles, so the edge of the grout float does not dig into any of your tile grout lines. Try to remove at least three quarters of the surface tile grout.
Step 4 To Grouting Tile- Clean Grout From the Tile Surface
After you have finished grouting floor tiles, the surface of the tiles will haze from the drying of tile grout. It depends on the temperature of the room and how dry your grout mix was, for when this will happen. The hazing could happen in 10 minutes or an hour after grouting floor tiles.
Pay close attention because the longer you wait after the grout has dried, the harder it will be to remove the remaining tile grout.
When you see the haze, dip a large sponge in clean water. Squeeze some of the water out of the sponge so that it is wet but not dripping.
Gently wipe the tile grout from the surface of your tiles. Do not dig into the tile grout lines, and be sure to rinse the sponge frequently with clean water.
If you do find hardened grout on your tiles a day or so after your tile grouting job, slightly dampen a pot scrubbing pad, and use a little elbow grease to remove it.
Step 5 To Grouting Tile- Joint Grout Lines
A new floor tile installation that has been wiped carelessly will look unprofessional. Tile grout should be just slightly below the tile surface. If tile grout is deeper it will be hard to keep clean.
Jointing is a very important step you will need to do to make consistent tile grout lines, and it will give you a much more professional look.
Wet your sponge with clean water, and wring it out so it is just damp. Ball up a corner of the sponge, and run it along each tile grout line, working first in one direction and then in the other. Have a bucket of water close by so you can continuously rinse the sponge, and when the water gets murky change it.
Be careful not to kneel or step on the tile grout lines. Allow the tile grout to dry. When it does It will be lighter in color.
Buff the surface of your tiles until they shine. If you find any holes in your tile grout lines, fill them with fresh tile grout and smooth the area out with a sponge.
Caulking your joints
Ceramic tiles and stone tiles will expand with the changes of temperature. This can cause these tiles to crack if you don't allow for a little movement, where tiles located on different surfaces meet, such as between a countertop and backsplash, a floor and wall, or even two walls that meet.
Do not grout these areas. Instead use a silicone caulk that matches your tile grout. It's up to you if you want to do this before or after grouting floor tiles, just be sure that whichever you choose to do first has fully cured before applying the other.
Once your grout has cured it'll be time for your final step of sealing your tiles and grout if your type of floor tile designs call for sealing or
sealing your tile grout alone, which always needs to be done.
