Anti-slip treatments and coatings for resilient floor coverings

Thursday, 16 July 2015

In a study, researchers investigated the effectiveness and durability of different categories of anti-slip treatments for resilient floor coverings in a long-term field test.

Adequate slip resistance of floor coverings is a prerequisite for safe walking. The incidence of slips and falls, however, indicates that insufficient slip resistance is a problem frequently arising in practice. Poor slip resistance can be a consequence of inadequate floor material and surface properties, or it can be caused by wear and maintenance. Various treatments and products are commercially available in order to improve or restore the slip resistance of problematic surfaces.

Due to wear loss of positive effect

Repeated measurements of friction coefficients showed that anti-slip coatings initially improved the slip resistance before gradually losing their positive effect, typically with a half-life period of about 3 months. Safety coatings as well as slip-resistant adhesive tapes increased the slip resistance effectively and proved to be relatively durable, although being affected by significant mechanical wear. Scanning electron microscopy showed that the predominant wear mechanisms of the investigated floor coverings and anti-slip treatments are roughening of smooth surfaces, smoothing of rough surfaces, and intrusion of hard particles into polymers. The main and probably general result of the EMPA study is that all kinds of anti-slip treatments (coatings, tapes) gradually lose their positive effect due to wear during use.

The study is published in: Safety Science, Volume 76, July 2015, Pages 12–20.
