Description
Unglazed Porcelain Mosaic Tile CHUNKY 15mm are over 5/16 inch thick and sold loose in bags of 1/2 kg, which is approximately 130 to 150 pieces. These are fine porcelain with solid color throughout. Raw, unpolished. The corners and edges are sharp. They will more naturally match the edges of any cuts you need to make, but you should smooth sharp exposed corners with the fine side of a marble file for safety reasons. These tiles and very hard and durable, but they can be cut with our Compound Tile Nipper.
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 130 to 150 tiles. Assuming a standard grout gap of approximately 1/16 inch, a bag of 1/2 kg will cover 60 square inches or 0.4 square inches. To cover 1 square foot, you will need about 3 bags. Use our tile estimator to calculate how much you need for your project.
Compatibility
For best results, these should only be used with thick ceramic and stone tiles instead of most glass. These tiles are 8mm thick, which is twice the thickness of most of the glass mosaic tile we sell. If you mount these on a flat surface alongside 4mm thick glass mosaic tile, then the glass would be recessed significantly, which might not look right because the corner edges of the porcelain tiles are pretty crisp (not rounded).
Use With Glass Tile
There is a way to use these with thinner materials, and that is to temporarily face mount the pieces on mounting tape or mounting paper and then press the sheet of tile into a bed of thinset mortar. The extra mortar beneath the thin glass tile will contract (or “thin”) as it hardens (“sets”), and that means the glass tile would still be recessed some compared to the thicker porcelain tile.
The unglazed porcelain is not glossy like glass, so there would be differences in sheen or finish between the two materials, but that is not necessarily a negative thing.
Cutting Porcelain Tile
This product 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. Corners can be sharp because this material is very hard. Exposed corners should be rounded with the file for safety reasons.

IMPORTANT INSTALLATION TIPS
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:
- Mount the tiles to the surface to be covered.
- Use a rag or small artists paint brush to apply GROUT RELEASE to the face of the tiles.
- 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.
