Anti slip paint for increasing safety on floors

In the UK, slips and trips cause more than the third of all injuries during working hours, and over 40% of injuries to the members of the public. Most of these injuries happen as a result of contaminated floor surfaces. They are also the reason behind long sick leaves and high compensation costs. Safety on floor surfaces is the responsibility of the employer, after all. An anti slip paint is a solution worth implementing due to its ability to effectively prevent slips and trips.

Slip resistance certification and standards in the UK

In most European countries, including the United Kingdom, the German National Standards (DIN) are used in assessing the slipperiness of floors in absence of European and British standards. Most coating manufacturers also base their product descriptions and qualifications on the DIN-standards. The ones relevant for slipperiness of floors are DIN 51097 and DIN 51130 and they are relevant followingly:

  • DIN 51097 | classification for floors in humid and wet areas where no shoes are worn
  • DIN 51130 | classification for workplace floors and areas of high slip risk or angled floors

DIN 51097 for wet areas

The DIN 51097 standard recognises three slip classes: A, B and C which assess the slip risk and where A- areas are the least slippery. The bigger the risk of slips and trips, the more attention the floor needs to become “antislip”. If a coating specialist assesses your floor as C, you know that means a highly slippery area.

A – Predominantly dry areas such as changing rooms
B – Showers, bathrooms, areas around swimming pools and bottoms of children’s pools
C – Sloping swimming pool edges

DIN 51130 for workplaces

This standard categorises floors by R-rating to determine the need for anti slip coatings and other measures. The values are based on the angle of the floor. The R-ratings include groups from R9 to R13. The lowest of these five groups is R9 which requires the least measures for anti slip properties. In turn, the class R13 substrates are subject to the strictest anti slip requirements.

Always, make sure you are properly informed about the anti slip paint classifications either by studying the manufacturer’s specifications or consulting a coating specialist.

Pendulum Testing according to the Health and Safety Executive

Whereas the most manufacturers base their product descriptions on the DIN standards, the British Health and Safety Executive (HSE) relies on pendulum testing. This testing method results in Pendulum Test Values (PTV) which are comparable to the ABC- and R- ratings.

  • High slip potential areas | PTV of 0-24
  • Moderate slip potential areas | PTV of 25-35
  • Low slip potential areas | PTV of 36 +

These values translate to the ABC rating as follows.

ABC valuePendulum test value
A21 – 31
B32 – 42
C45 +

The pendulum test values can also be compared with the R-rating system. The PTV and R-ratings relate to each other followingly:

R-rating valuePendulum Test Value
R911 – 18
R1018 – 34
R1134 – 51
R1251 – 70

Anti slip coating in 1 of the 3 ways

When it comes to applying anti slip paint in industrial, commercial or domestic environments, it is crucial to know what the options are. Here you will find three ways for creating anti slip surface by coating, and their pro’s and con’s.

1. Coating + anti slip additive

What it is: anti slip coating made by adding rough grit or granula into a floor coating. The grit can either be mixed in the floor coating before applying or even sprinkled on the wet layer of paint. These non slip additives are available in different roughness- grades depending on the required anti slip class. The anti slip class has also an impact on the amount of grit needed.

The table below presents the most commonly used types of additives used for making non slip coating.

Type of gritAnti slip valuegradesAdditive for
Polyurethane (plastic granula)MiddleRoughAll 2 component coatings
Glass pearlsLightMiddle to roughTransparent 2 component coatings
Dispersed polyurethane IndustrialMiddleAll coatings for wood
Aluminium silicaatIndustrialLight, middle to roughEpoxy coatings for wood, metal and concrete
Sintered flintMiddleLight to middleAll 2 component coatings

Pro’s and con’s: The biggest advantage of the additives is naturally, that they can be combined with almost any coatings. This gives the freedom to choose a preferred coating type or brand. It is also possible to determine the roughness. However, the freedom is also a disadvantage; the optimal mixture may be complicated to define; and sprinkling the additives requires some experience, to get it done right. Fortunately, coating experts can help you achieve the optimal anti slip surface.

2. Anti slip coating in 2 components

What it is: A pre-mixed coating which contains the right amount of anti slip granula for the optimal result. The coatings are often divided into categories based on the need for slip resistance; Offshore (corrosion resistant anti slip paint for metal), Industrial (chemical and abrasion resistant coatings) and commercial (aesthetically appealing non slip coatings). Here below you can find some examples:

CategoryClassificationProductPrice (RRP) per litreTheoretical coverage per litre
IndustrialDIN 51130 R11Rust Oleum Supergrip£12.505 m²
CommercialDIN 51097 BGrip Antislip£33.505 m²
OffshoreDIN 51130 R12Pro-Tech£89.75

Pro’s and con’s: Due to the fact that the coating already contains the anti slip additive, you get the optimal results applying the product as it is. Additionally, you get all the benefits of a 2K coating: for example higher abrasion resistance, chemical resistance and durability. The downside is that 2 component coatings are little more difficult to apply if there is no prior knowledge about applying 2K coatings. Furthermore, the prices are slightly higher, and there are not so many brands to choose from.

3. Nano anti slip coating

Nano anti slip paint does not change the appearance of the substrate.

What it is: a two component coating with polyurethane (exterior) or epoxy (interior) in combination with chemical nanotechnology (silane with UV-additives). This is the way to combine the numerous benefits of nanocoatings to a antislip function. This coating differs from the other anti slip paints by being transparent and completely colourless. It also has a satin finish. These properties guarantee that the natural looks of the substrates will not be affected.

It is also possible to add special hard Kalium silicate pearls into the coating to increase its anti slip properties and to make the coating rougher and more resistant to abrasion.

Pro’s and con’s: The main benefit of this coating is that it results in a transparent, extremely slip resistant surface. It is thus the ideal anti slip paint for wood floors and stone- like surfaces. Due to the nanoparticles the coating is also hydrophobic and oleophobic making it easy to clean and maintain. The only downside is that the coating is rather new in the market, and therefore, not yet offered by many manufacturers.

Making small surfaces slip resistant with anti slip spray and grit

If you are planning to apply anti slip paint on a very small surface, an anti slip spray is an option to consider. Anti slip sprays are suitable for multiple substrates and they are applicable in interiors and exteriors. The sprays can for example be used as non slip paint for concrete steps or small metal surfaces. Essentially, the sprays are suitable as anti slip paint for stairs, metal, wood, concrete, stone and tile/ ceramic surfaces.

You can also purchase a small portion of anti slip additive (grit) to mix it yourself into any almost coating. For example Rust-Oleum offers a couple of solutions for small surfaces:

  • Additive | Rust-Oleum anti slip grit (rough) | 1 litre: £13.00
  • Spray | Rust-Oleum Supergrip Anti Slip spray for metal, wood, stone and concrete | 500 ml: £33.00
