Installing Marble Granite Floor Tiles
In general, marble and granite flooring tiles can be installed in the similar way
to installing ceramic tiles. The major difference is marble or granite is much
heavier than the ceramic. As the first step of installation, the floor must be
cleared and cleaned completely. If the tile are to be laid on top of wood base,
make sure the entire base is sturdily secured. Otherwise, the tiles could crack
in future. If the floor needs to be stabilized, add joists or jack supports to the level below the floor. After checking for stability, you need to check to be sure your floor is level. Using a long level, check for slope in the floor. Also check under the level to look for dips in the floor. If necessary, build up the floor. A level floor is
fundamentally important for installing a marble or granite floor.
A cement backer board can be screwed directly to the plywood. This will reinforce the floor, since marble tiles are relatively heavy. The tiles do not give and are prone to cracking if the floor is not sturdy and unyielding. If you choose not to use a cement baker board, you will need to reinforce your floorboards with another layer of plywood. The tiles will be applied using a thin-set adhesive.
Once you have prepared your floor, it is time to start installing your marble or
granite tiles. Start by finding the center of the room. Measure both the length and the width, and put a chalk line down the center of each. Where these lines intersect is the center of the room. Now, the next step is very important. Lay out your marble
or granite tiles in a test run. This is important because if you end up with a tiny piece of marble at any end, you will need to shift your center line a little to avoid having a tiny edge on one end of your floor. To keep a symmetrical look, have the starting tile straddle the centerline if needed.
Now you are ready to begin laying your marble or granite flooring tiles. Always
begin with the piece in or near the center. Trace around the outside of this tile. Apply mortar, preferably a thin-set mortar, inside the lines you traced. Place your tile on the mortar. This is your reference point for the rest of your floor. From this tile, spread your mortar and use a trowel to notch it. When applying mortar over seams in the floorboards, apply mesh mortar tape to the seams. This prevents cracks in the grout when you are finished. After putting each tile on the mortar, place a 1/16-inch spacer between it and the next tile. This will ensure that the finished project has and evenly spaced appearance.
Once you have finished laying your tile and given the mortar time to dry, it is time to seal the marble.
We suggest to have a professional contractor to perform sealing job. Remember to
seal marble or granite surface every nine to eighteen months.
Advantages of Marble Granite Flooring
The main advantage of any type of tile flooring, including marble and granite, is that if it is damaged or stained, you only need to replace the damaged tiles, not the entire floor. With a carpet or hardwood floor,
any significant damage would require replacing the flooring for the entire room. You may want to consider buying some spare tiles, in case you need to replace some in the future.
As marble and granite has naturally random textures, you may not be able to find an exact match to your flooring after a few years.
Now you have your a stunning marble or granite floor. You can ensure its longevity by
doing a few simple things. First, whenever possible, remove your shoes before walking on the marble
or granite surfaces. Shoes pick up oil and dirt that can scratch and stain the floor.
Equal importantly, make sure to sweep or vacuum your floor before popping, so
the floor surface is not scratched.
