A Marble Tile Installation Is One Of The Most Attractive of Stone Flooring No matter If You Use a Glossy Marble Floor Tile or Rougher Tumbled Marble tile.


A marble tile installation can consist of the beautiful glassy appearance of glossy marble floor tile, or the handsome rustic look of tumbled marble tile. Both make for one of the most attractive of Stone floors.

You'll want your floor tile installation to be as simple as possible. So before beginning any floor tile installation be sure first to draw your reference lines and Dry lay your tiles to determine the look you desire.

You install Marble thresholds at the end of your marble tile installation, So leave out the row of Marble floor tiles that will meet the threshold until you're ready to install it.

Marble thresholds must be the right length for your doorway. They need to fit in the inner side of the door jamb.  They will also need to sit on the outer edge of the door when it's closed.

Sometimes you may need a wider marble threshold than your previous one. You may need it wider to cover any exposed subflooring.

If you use a wooden threshold, just lay your marble floor tile up to the inside edge of the closed door. And the threshold will sit directly under the door.
For now, let's make the choice.

Tiling Tips for Marble Floor Tile

* Tumbled marble tile unsealed is very porous, So without the protection of a tile sealant is very prone to staining more-so than polished Marble floor tile. 

* Polished Marble has a glass like finish that can be very slippery when wet. Tumbled Marble tile has a rough rigid surface that makes for a safe slip resistant flooring. And once the tiles are sealed Tumbled Marble tile becomes water and stain resistant making for an excellent kitchen or bathroom floor tile,

* You'll need to seal tumbled marble tile before and after grouting tile to protect it from staining.

* For grouting Marble floor tile it looks best with the narrowest of grout lines. The size of the spacer you choose determines the size of your grout lines.

* Marble floor tile is best installed over a cement backer board tile underlayment.

* It's best to use a white colored Thinset Mortar tile adhesive
for Marble Tile,  because colored Mortar may show through these translucent  tiles.

* You'll need to create a beater block to tap your Marble tiles in place. Make a beater block out of a 12 inch 2x4 wrapped in scrap carpet or something similar. The material softens the blow while tapping your tiles into place.

* Marble tile is OK to tap with a beater board and mallot, But If you are using limestone or any other type of fragile tiles, it's best not to beat them!

The Marble Tile Installation

 Mix And Spread Your Thinset Mortar

For this marble tile installation, we'll be using a white latex reinforced thinset mortar. It's best to use white thinset mortar as a colored mortar may show through the tiles.So, mix up a batch of White Thinset Mortar.

Move a glob of thinset within a reference line on a section of the floor located in a corner that's opposite to the exit you'll be using. Hold your notched trowel at a 45-degree angle.

Allow the teeth to scrape the subfloor gently.  And comb over the thinset with long sweeping strokes while keeping the angle of your trowel consistent. Try to spread the thinset mortar within the reference lines.

If you're using white thinset and accidentally go over the reference line, it's more forgiving as you should still be able to see the lines.

Back Butter your floor tile

Use your margin trowel to apply a  layer of thinset to the back of a tile. Back butter each Marble floor tile as you place them.

Place Your Spacers Between Your Floor tile

Insert your spacers between the corners of each tile. For a Marble floor tile installation, it is always best to use the narrowest of grout lines, So use the smaller spacers.

Lay your floor tile

Set each marble floor tile precisely, so you don't have to slide it any more than an inch or so to adjust it. Align your first Marble floor tile in the intersection of two of your tile reference lines, and set additional tiles against it.

Tap Your Marble Floor Tile With Your Beater Board

 Once you've finished laying one section or grid of Marble tile, Check for any tiles higher or lower than the overall surface of the tiles.

Tap the  high tiles into place by using your beater block and mallet. If you find tiles that are sitting lower than the other tiles, pry them up using a utility knife.  Then spread enough additional thinset on the back of the tile to make it level,  then set it back in place. And level it with the beater block and mallot.

Check Your Marble Tile Installation For Uneven Floor Tile

To check your floor tile installation for uneven tiles, Lay your bubble level over each grid of tiles and make sure that the bubble lands in the center of the glass.

Adjusting Your Floor Tile

Bigstock Grout Setting

If you need to adjust a tile slightly, place your hand on top of the marble floor tile with your fingers, spread out. Press gently as you slightly slide the tile.

You should be able to make a small adjustment, but if you feel resistance, followed by a sudden movement, the thinset has probably already begun to set! When this happens, you should pick up the tile, and scrape the back of the tile to remove the thinset. Then start over with fresh thinset, and reset the tile.

At some point during your marble tile installation, you're going to need to cut your the edge tiles.

Clean Up

Clean up any excess thinset that squeezes up between your marble tiles as you go.  It's best to do this right away because Thinset Mortar is much more challenging to remove once it hardens.
You can use a spacer or a carpenter's pencil to dig out any thinset from between the tiles. If necessary you can use a flat head screwdriver to scrape out the excess thinset the next day.

Adding Your Threshold To Your Marble Tile Installation

When you are setting your last row of marble floor tile, spread your thinset into the doorway. Stop along the outer edge of the doorstop, and set your threshold, before placing your last row of marble floor tile.
You can adjust the placing of your last row of tiles, or the threshold as needed, to align them into a nice clean fit.

Grouting And Sealing Marble Tile

Congratulations on your new marble tile installation. If you are using Polished Marble Tile, allow your thinset to harden in about 12 hours. Then you are ready to finish the job with grouting your tiles and then sealing them along with the tie grout.

If you are using tumbled marble tile, you will seal your tiles first, then grouting your tiles, and finish up by sealing the tiles again along with the tile grout.
