Slip resistance has to work when the floor is wet, not only when it is dry.
What the rules say
The ADA Standards state that floor and ground surfaces "shall be stable, firm, and slip-resistant." The ADA does not set a number. OSHA sets no coefficient of friction (COF) requirement. ANSI A326.3 sets a wet dynamic coefficient of friction (DCOF) of 0.42 or greater. Your facility and your authority decide which standard applies to a room.
Ask for test data
FlooringInc does not publish measured slip-resistance values. A "slip-resistant" line on a product page is not a test result. If your specification calls for a COF value, send us the SKU. We will request the test data from the manufacturer. Keep that data with your project records.
Send us the SKUs. We will ask the manufacturers for the test data.
Surface and material choices
- Rubber: Our guides call rubber slip-resistant, even when wet. It also absorbs some impact, which helps if a person falls.
- Vinyl: Vinyl gives good slip resistance with a textured surface. It may not be as slip-resistant as rubber in wet conditions.
- Tile: A textured tile, such as a wood grain or stone texture, gives more traction than a fully smooth tile.
- Carpet: Carpet gives decent traction. Use low-pile commercial carpet that is glued or tacked down.
Texture costs cleaning time
More texture gives more grip, but it also holds more soil. The American Animal Hospital Association describes this as a balance of cleanability and slip resistance. A coin or diamond pattern grips in a wet room, but soil stays in the pattern. Choose the balance for each zone. Put the most texture where the floor is often wet, such as a bathing area.
Some product pages describe the surface. For example, the Envee Tacky Back page says its 22 mil wear layer has aluminum oxide and is slip and stain resistant. That is a description, not a COF value. Place mats at all entrances to stop tracked-in dirt and moisture.
