Best Answer

Yes, you can use unsanded grout for floor tile but you'd only want to use it if the grout lines were 1/8" wide or less - like for granite or marble tiles.

If using those, be sure you have a pefectly flat surface.

ANSWER:

You never want to use sanded grout with marble. If the marble has to be restored or re-polished for any reason the sand in the grout with act like sandpaper on the stone.

Can you use wall tile grout on floor tiles?

You can. It is less gritty but it works. Edit - While this is true, it's important to understand the wall grout is designed for thinner grout lines, so if you use it on the floor, make sure your grout lines are thin. Otherwise, the grout will crack.


Can the color of grout be changed?

Yes, you can change the color of the grout. There are products that you can use to try to die the grout or you can just have your tile re-grouted.


Can you use White grout to install porcelain tile?

Not JUST a grout no. You can get a cement that will also work as a grout but a pure grout would not have the adhesion required to stick the tiles to the wall properly, you should not use it as a cement.


Is it good to seal tile and grout?

Yes.... But if the tile is glazed and/or the grout is epoxy (unlikely unless in a commercial building) these do NOT need to be sealed (neither will absorb water so they won't accept the sealer). The rule of thumb is to put a few drops of water on the tile and the grout, if it soaks in within 30 seconds it needs to be sealed. Never use a topical sealer. Always use a waterbased PENETRATING sealer. You will need to reapply bi-yearly or yearly in most situations, more if the tile is exposed to water. Hope this helps..........


How to Install Duraceramic Tile?

Duraceramic tile will not chip, break or crack like regular ceramic tiles. Manufactured in a 16" square format with scoring, you can cut the score lines to make 4 tiles 8" square. They are best installed in dry residential rooms. This leaves the bathroom out. Use the proper underlayment for the type of floor you are installing Duraceramic tile on. Spread Congoleum Duraceramic tile adhesive on the underlayment using a tile trowel. Allow to dry until tacky, then set the tiles with spacers. Use a roller to press tiles into place, and allow to dry 24 hours. Grout with Congoleum Duraceramic grout.

What grout is used for floor tile?

Most often, sanded grout is used for floor tiles because the grout lines are usually greater than 1/8" wide. Sanded grout is necessary for the wider lines to give added strength, and to keep your grout from cracking and chipping out. Unsanded grout must be used if your grout lines are narrower than 1/8", because the grains of sand in sanded grout could cause air pockets and prevent good adhesion to your tiles - and it will crack and chip out as well. Sanded and unsanded grouts are cement-based. One alternative grout on the market is epoxy-based. It is neither sanded nor unsanded, but will work fine in either narrow or wider grout lines. If your grout lines are wider than 1/2", or if you are using saltillo tiles, you must use saltillo grout. Other grouts will not handle this wider width.

Will using both sanded and unsanded grout on your back splash look okay if you have both 1-16 in and 1-2 in gaps to grout?

You should use the grout that will work best for the biggest grout space that you need. So for a grout width like you described, 1/16 to 1/2, you should use sanded grout. Unsanded grout will look terrible in a 1/2" grout joint, but sanded grout will look great in both. Use sanded.

What happens if you make a mistake and use non sanded grout in a ceramic tile joint of one quarter inch?

Non Sanded grout can be used in any size grout joint but is ideal in smaller joints usually up to 1/4" The main draw back to using unsanded grout in larger joints is that it may crack over time. If you are unwilling to remove all the grout and use a sanded grout, it is best to make sure the grout is cured and sealed properly to limit and minimize cracking.

How do you tile a bathroom?

To tile a bathroom, you must first find the center of the floor or wall. This is where you will lay your first tile. You work out from there. This way you have the cuts where they are less noticeable. Use a trowel to place tile glue on the tiles, put them in place. Use spacers to keep them apart at an equal distance. Use a tile cutter to cut tiles in areas where a whole tile is not needed. Once you are done, remove the spacers and use a trowel to grout between the tiles. Wipe away excess grout with a wet sponge.
