Outdoor Test Shows Cleanability of SparkleTuff™ Transparent Anti-Slip Floor Coating

In order to demonstrate the cleanability of transparent SparkleTuff™ (“Sparkle-tough”) Anti-Slip floor coating, we placed seven contaminants on the surface of a porcelain tile coated with SparkleTuff™, as shown in Fig. 1. They are, clockwise from top left, black coffee (a long patch): cabernet sauvignon red wine; yellow mustard; mud from amended adobe (clay) soil; […]

Physical Therapist’s Glowing Endorsement of SparkleTuff™

Our clients and their information are confidential. Many parties don’t want it known that they have had slippery floor problems — it tends to bring claimants (legitimate or fraudulent) and their lawyers out of the woodwork. However, one SparkleTuff™ user, a physical therapist, was so pleased she volunteered to let us use her comments. She […]

Slip Resistance Standard for Swimming Pools, Spas, Hot Tubs, Splash Pads, etc.

The National Sanitation Foundation (NSF), together with American National Standards Institute (ANSI) and National Standard of Canada (CAN) established a slip resistance standard for recreational water facilities. Formalized in NSF/ANSI/CAN 50 – 2019, the standard requires a wet Slip Resistance Value, SRV, of 40 or greater, measured using the pendulum slip resistance test method. Though […]

Germany’s DIN 51130 Slip Test: What’s it Good For?

In Europe a slip resistance test for flooring is prescribed by German Institute for Normalization (DIN) standard DIN 51130. A person wearing industrial-type treaded shoes walks, facing downslope, on a variable-angle ramp which has the flooring to be tested on it. The flooring is coated with motor oil. The walker (without holding the handrails) adjusts […]

SparkleTuff Outdoors on Level Surface and Stairs: 30-second video

The video below shows an outdoor level surface and stairs at a large mall, coated with transparent SparkleTuff™ Anti-Slip. A pedestrian walks down the stairs, which are partially wet from the previous day’s rain. With a material cost of about a dollar a square foot, SparkleTuff™ has excellent wet slip resistance by all respected test […]

A Review of Standards for Pedestrian Slip Resistance Testing

There are a number of floor slip test methods established by standards-setting organizations that assess pedestrian slip resistance. Here we’ll review the most widely known and current ones. They are distinguished by the devices used in the testing. Terms such as DCOF rating, coefficient of friction, slip coefficient, slip resistance rating, and friction coefficient all […]

Beware of Slippery Finished-in-Place Floors Installed by Clueless Contractors

Some floors are covered with premanufactured stuff, such as marble, granite or ceramic tiles, wood, or vinyl composite tile. Other floors are created in place — including epoxy, terrazzo, and concrete. Topical sealers added to premanufactured floors also constitute a finished-in-place surface — the pedestrian is not walking on the flooring, but on the sealer. […]

Roughness and Wet Floor Slip Resistance

We all know intuitively that roughness has a lot to do with floor slip resistance. Very smooth floors tend to have low wet slip resistance, and to some types of shoe solings (as on some dancing shoes) can have low dry slip resistance too. However, “rough” appearing floors aren’t always slip-resistant, and this has to […]

Floor Slip Rating: SCOF vs. DCOF

Static coefficient of friction (SCOF) was formerly used to measure the slip resistance of a wet floor in the USA, but the test method (ASTM C1028) was withdrawn by the ASTM in 2014. Experts in the USA now know to use dynamic coefficient of friction (DCOF), as the rest of the world has been using […]

ANSI A326.3 Acutest Does Not Predict Likelihood of Slip

A widely used floor friction test, American National Standards Institute A326.3, states in its introduction that “it can provide a useful comparison of surfaces, but it does not predict the likelihood a person will or will not slip on a hard surface flooring material.” The test assesses wet dynamic coefficient of friction (DCOF) using the […]
