An anti-skid tile is a tile whose surface is made to grip better underfoot, especially when wet. The grip comes from texture, grit in the glaze or a structured face. "Anti-skid" is a catalogue word, not a test result.
Two tiles both sold as anti-skid can perform very differently. What protects you and your customers is a measured slip rating on a test report.
How tiles are made anti-skid
Morbi factories use a few methods, often combined:
- A structured face pressed into the tile, such as stone, riven or grooved textures.
- Fine grit, such as corundum, added to the glaze or sprayed on before firing.
- A matt or rough glaze instead of a smooth one.
- Unglazed full-body porcelain with a naturally textured surface.
Each method has trade-offs. Deep texture grips well but holds dirt and is harder to clean. Grit in a glaze grips well when new but can wear down in heavy traffic. A full-body textured tile keeps its surface longer, because wear exposes the same material.
The same design is often sold in two surfaces: a smooth one for indoors and a textured one for outdoors. Check which one your sample is. A buyer who approves the indoor surface and receives the outdoor one, or the reverse, has a real problem on site.
Where anti-skid tiles are used
- Outdoor paths, terraces, balconies and steps that get wet from rain.
- Parking areas and ramps, where water and oil collect.
- Pool surrounds, showers and changing rooms.
- Commercial kitchens, food plants and other wet working areas.
- Entrances, where people bring water in on their shoes.
Buy on a rating, not a word
Slip resistance is measured by several methods, and each market prefers its own. Germany and many export buyers use the R rating under DIN 51130. The UK uses the pendulum test value. The US uses the dynamic coefficient of friction under ANSI A326.3. Our main guide on slip resistance and R ratings explains each method and its thresholds.
For outdoor and wet areas, buyers most often ask for R11 or higher. Our article on R11 and R12 slip ratings covers where each one is used.
Checks before you order
Ask the factory for a slip test report from an independent laboratory, for the exact design and finish you will buy. A report for a different surface in the same series does not count. The texture, glaze and grit change the result.
Then check the shipped goods against the approved sample. Grit levels and texture depth can drift between production runs. Keep a signed reference sample and compare by eye and touch at inspection.
Finally, warn your customers about cleaning. Textured tiles need a stiff brush or machine scrub. Waxes and sealers can reduce grip, so check the factory's care advice before you pass it on.
