This unglazed and skid resistant porcelain mosaic tile is sophisticated, stylish, and suitable for any floor and wall application, including but not limited to hall ways, bathroom floors, and pools surrounds. Sheets of tile are backed on mesh for easy installation. The tiles can also be peeled off from the mesh and installed individually, mixed with other colors. This tile can be installed in wet areas as well as dry areas. Please note that the images shown are actual photographs of the tiles, however, shade and size variations are inherent characteristics in all mosaic tile products. These variations are a trademark of hand-crafted quality and adds to the unique beauty of your individual mosaic.

A way to determine the skid resistance of porcelain tile is the DIN (German Institute for Standardization) classification for tile slippage. One of the methods this system uses is the DIN 51130 set “ramp test”. In this set, various surfaces are rated in one of five groups according to their degree of slippage. To determine which of these groups a material should be classified in, operators apply it on a surface that is gradually sloped and then spray it with motor oil. A person wearing shoes walks up and down the slope until they start slipping. The value in degrees of the slope reached before they start slipping determines the classification of the material in class. Here are the ratings:

• Rating R9 – Suitable for a less than 10° slope (minimal friction)
• Rating R10 – Suitable for a 10° to 19° slope (normal friction)
• Rating R11 – Suitable for a 19° to 27° slope (normal friction)
• Rating R12 – Suitable for a 27° to 35° slope (high friction)
• Rating R13 – Suitable for slopes more than 35° (very high friction)

Also, another DIN 51097 set classifies tiles from A to C for non-slip suitability. This test uses a soap solution instead of motor oil and participants are barefoot:

• Rating A – Suitable for slopes 12° to 17°
• Rating B – Suitable for slopes 18° to 23°
• Rating C – Suitable for slopes >24°

V1 - Uniform Appearance - Differences among pieces from the same production run are minimal
