Marble Mosaic Tiles Tumbled 9/16-Inch are sold loose by the pound for making mosaic art, murals, and floor medallions. The NOMINAL dimensions are 15mm (5/8 inch) x 3/8 inch thick, but the tumbling process removes material, particularly with softer varieties of stone, and so the width of most stones is probably closer to 9/16 inch than 5/8 inch. Make sure you read our IMPORTANT INSTALLATION TIPS below to avoid grout staining and enhance stone colors.
Marble Mosaic Tiles Tumbled 9/16-Inch
- tumble-finished natural undyed stone.
- material varies by batch for color, pattern, size, and sharpness of corners.
- Each tile is approximately 9/16 inch x 9/16 inch, with variation by batch and stone type.
- Coverage: 80 tiles will cover approximately 1/5 square feet when using a standard grout gap of 1/16 inch.
- Coverage: 369 tiles will cover approximately 1 square feet when using a standard grout gap of 1/16 inch.
- Thickness: 3/8 inch NOMINAL.
- Recommended for dry locations where water cannot pool.
Many varieties of marble mosaic tile are not technically marble. Other varieties of stone are used to provide colors not available in marble, but all our marble mosaic is undyed natural stone with an unsealed tumble finish.
Expect Product Variation
This product will vary by batch for several reasons, but mainly because it is a natural material that varies from quarry to quarry and even within the same quarry. Expect variation in product color, pattern, size, and roundness at the corners.
The size of the stones and the roundness/sharpness of the corners will vary based on the hardness of the stone. Softer stone tumbles faster than harder stone.
Never Install Tile in Batches
It takes a tremendous amount of energy to cut stone tile. To offer the tile to us at an affordable price, our factory has to be practical and use looser standards of quality control. If consistency is extremely important to you, then make sure you use something other than natural stone. However, you should be aware that all forms of mosaic tile can and do vary by manufacturer batch, and so you should never order your materials in stages or begin installing tile before you have all that you will need. Even the most expensive brands of Italian glass tile comes with warnings to inspect and mix different boxes of their tile before you install it. This caveat certainly applies to natural stone produced in China!
There are approximately 80 marble mosaic tiles per pound, which covers over 1/5 sq ft with a grout spacing of 1/16 inch. Use our tile estimator to calculate how much you need for your project.
Tile thickness is approximately 3/8 inch, which is thicker than our regular glass mosaic tile. If you are pressing tiles into thinset mortar or concrete, then it would be possible to use these with thinner glass tile, but it would be problematic if you are gluing tiles to a flat surface.
Our Compound Tile Nipper is the recommended cutting tool for stone and other hard materials such as porcelain. A Marble File is extremely useful for shaping hard materials. It is much easier to file off a tiny amount than it is to try to cut off a tiny amount.
IMPORTANT INSTALLATION TIP
Grout will stain unpolished and unsealed stone because it is porous. The stone has to be sealed with a tile and grout sealer BEFORE you grout it. (Or a type of sealer known as “enhancer” if you want to make the colors darker and richer.) However, you shouldn’t seal any surface where grout or glue needs to stick to the stone. Here is what we recommend for presealing porous materials before grouting:
- Glue or cement your mosaic tiles into place.
- Use a rag dampened with sealer or a small artists paint brush to seal only the top faces of the tiles.
- Take care not to drip sealer down between the tiles or down the sides of the tiles.
Tile and Grout Sealers are available at building material stores. Enhancers are also available there if you want to make the colors of your stone darker and richer. Both products are penetrating sealers instead of coatings, which means they don’t form a layer over the top of the mosaic.
Using Marble Tile for Outdoor Mosaic Art
Most people think that stone is more durable than glass for outdoor mosaic art, but actually the reverse is true for several reasons:
Not all stone is hard, and natural stone only comes in so many colors. To get the range of colors needed to make a mosaic, softer varieties of stone such as honey onyx (actually a calcite) are sometimes all that is available for a particular color. This is especially true when you are discussing affordable types of stone. Sure, emeralds are a rich green, but they are also relatively rare, small and expensive.
Porosity and Freeze Damage
Glass mosaic tile is non-porous, and thus water cannot penetrate into it and then freeze and expand, which causes porous stone to crack and flack away. Keep in mind that the reason we have so many ancient Greek and Roman mosaics left after all the millenia is that the Mediterranean climate is relatively warm and dry. It also helped that many of the ones we now have were buried under volcanic ash for centuries.
Remember that not all marble mosaic tile is technically marble, and even if it were, marble isn’t that hard, and it is also susceptible to chemical damage by naturally occurring substances. For example, the products of decaying organic matter such as rotting leaves are acidic. Marble dissolves in acid. (You can actually listen to mable fizz when you pour vinegar on it.) This is how the acid rain from automobile exhaust in European cities has melted ancient statues. Other varieties of stone are also vulnerable to organic acids and other natural substances.
How To Make Marble Mosaics Last
Marble (and the other stone types described as marble) are best used for indoor mosaics where water cannot pool on the surface. However, marble can be used outdoors provided you seal it very well with a tile and grout sealer and check the seal every few years to make sure that water is still beading on the surface instead of soaking in and wetting it. This really isn’t extra work. Even if you used non-porous glass tile, you would still need to seal the mosaic and periodically check the seal because the grout between the tiles is porous and vulnerable to freeze damage.
Outdoor mosaics made from marble should be on vertical surfaces such as walls instead of horizontal surfaces such as the seats of benches or walkways.
