SKU: Polished-Porcelain-Mosaic-Tile-15mm Category: Tags: , , , , , , ,


Polished Porcelain Mosaic Tile 15mm are 4mm thick, the same nominal thickness as most of our glass tile. They are 15mm (roughly 5/8 inch) on each side and sold loose in bags of 1/2 pound, which is approximately 130 pieces. These are fine porcelain with solid color throughout. The tops are mechanically polished (buffed) but not glazed. They can be cut with our Compound Tile Nipper, and we recommend smoothing cuts in hard materials using the fine side of a marble file. These tiles and very hard and durable. Please note, the polished surfaces still have small incidental pits that can be stained with grout and colorants.

Grout Staining in Pits

Note that the polished surfaces still have small incidental pits that can be stained with grout. This isn’t a problem for our projects, and we have simply ignored the issue in our art. Do not order if this is a problem for your project.

Never Install Tile in Batches

Tile varies by manufacturer batch, and sometimes a color will go out of stock for an extended period if the manufacturer isn’t making it. You should never install tile before you are sure that you have all the tile you need. You could attempt to order more and find that the manufacturer has changed the color or discontinued it.

Product Coverage

Some colors are sold loose in 1/2-kg bags of approximately XXX tiles. Assuming a standard grout gap of approximately 1/16 inch, a bag of 1/2 pound will cover 55 square inches or 0.4 square feet. To cover 1 square foot, you will need about 3 bags. Use our tile estimator to calculate how much you need for your project.


The Polished Porcelain Tiles are 4mm thick, the same nominal thickness of most of our glass tile. They also have a glossy finish similar to glass.

Cutting Porcelain Tile

Polished Porcelain Mosaic Tile 15mm is not soft like most glazed ceramic tile. Porcelain is extremely hard, but it can be cut. Our Compound Tile Nipper is the recommended tool for hard materials like stone and porcelain. A Marble File is also required for smoothing the edges of cuts and shaping the pieces. Exposed sharp edges should be rounded with the file for safety reasons.

Polished Porcelain Mosaic Tile 15mm

  • sold by 1/2 pound, which is approximately 130 pieces.
  • fine porcelain with solid color throughout.
  • crisp edges, which more naturally matches cut edges.
  • Each tile is 15 mm x 15 mm x 8 mm thick (approximately 9/16 inch x 9/16 inch x 5/16 inch)
  • Coverage: 1/2 pound will cover 0.4 square feet when using a standard grout gap of approximately 1/16 inch.
  • Frost-proof, impervious to liquid.
  • Suitable for indoor or outdoor use.


For architectural installations, the manufacturer recommends that the porcelain tile be installed with a latex-modified thin set mortar instead of glue. For dry indoor mosaics, we use Weldbond glue.

Porcelain is essentially non-porous and impervious to moisture, and so it is supposedly not stained by grouting, but we have noticed discrete pits and divots in the surface of the tile that can be filled with grout. For this reason, we recommend using GROUT RELEASE (from a building materials store) on the mosaic before grouting:

  1. Mount the tiles to the surface to be covered.
  2. Use a rag or small artists paint brush to apply GROUT RELEASE to the face of the tiles.
  3. Take care not to drip excess GROUT RELEASE in between the tiles or down the sides of the tiles or any place grout will need to bond.
