Non-Slip Coating or Anti-Slip Treatment?

Non-Slip Coating or Anti-Slip Treatment?

Non-Slip Coating or Anti-Slip Treatment?

Often, floor coverings such as ceramic tiles or marble are selected because of their aesthetic appeal. However, aesthetics often compromise on safety. Many floor coverings are not slip-resistant, especially in wet conditions. Therefore, designers, architects and builders may select a non-slip or anti-slip product to treat particular areas.

So which solutions are available and how do I know which solution is best? There are two main solutions available: non-slip coatings and anti-slip treatments. Lets have a look at both solutions and list some advantages and disadvantages of both solutions.

Anti-Slip Treatment

Anti-slip treatments are generally an acid etching technique that increases the surface roughness by chemically changing the structure of the tile surface. The process involves a hazardous etching agent which attacks the calcium in the flooring or reacts with the glaze and silica composite of tiles. The acid creates tiny cracks in the surface which makes the surface feel more “rough”.

Effectiveness of anti-slip treatments

The effectiveness of acid etching treatments depends on the strength of the acid and the dwelling time. Although this solution is often used because acids are extremely cheap, there is minimal evidence on the functionality of these treatments. Much of the marketing of acid treatment is inconsistent and to validate such claims, generally, “in-house” testing report are provided. Rarely do these treatments meet the Australian Standard for Slip Resistance, especially in wet conditions (Whitfield, K, Bridge, S, Mathews, S. 2005, ‘Selecting Coating for Tiled Floors’, The University of Sydney: Faculties of Health Sciences and Architecture).

Only wet pendulum testing used in accordance with AS/NZS 4586 or AS/NZS 4663 can check the onsite slip resistance of non-slip or anti-slip treatments. So the effectiveness can only be tested after installation. To summarise, etching solutions create tiny cracks in the surface and have limited functionality in wet conditions. When acids are used incorrectly, they can cause irreparable discolouration.

Non-Slip Coatings

Non-Slip Coatings work by creating a non-slip layer on top of the surface. So besides providing slip-resistance, they also work as a sealer and create a protective layer on the surface. Another advantage of non-slip coatings is that they can be applied on a wide range of materials without damaging the surface. Moreover, non-slip coatings like Swiss GriP are transparent and UV-stable. Therefore, they are invisible and do not compromise on the design element of a floor.

Effectiveness of non-slip coatings

Because non-slip coatings create a consistent finish on top of the surface, the effectiveness of a coating can be tested by independent institutions like CSIRO. Such institutions will test the slip-resistance rating of the non-slip coating in accordance with AS/NZS 4586, in wet and dry conditions. So unlike etching treatments, non-slip coatings can provide test reports from independent test institutions, which will show proof of functionality of the coating. Swiss GriP Non-Slip scores the best slip-ratings and is certified by CSIRO. All our test reports are available upon request.

Non-Slip Coating or Anti-Slip Treatment?

Because Non-Slip Coatings are often high build polyurethanes or epoxy’s, they are generally more expensive than anti-slip treatments. So if you are on a budget, you might favour an anti-slip treatment. However, if you care about safety and prefer a solution that works in any situation, a non-slip coating is the way to go.
