anti slip paint requires no warning sign

Anti slip paint makes surfaces safe to walk on

Slips and trips are a serious problem, both at home and in the workplace. In Hong Kong, slips and trips account for a great number of all workplace injuries, and most accidents involve slips. If you are an employer, you have duty of care to provide a safe workplace for your employees, and are liable if you neglect it. Fortunately there is a simple remedy: an anti slip paint or non slip coating is easily applied and effective in preventing slip-caused injuries.

Stairs are the leading cause of slipping, but any floor that is wet or dirty becomes a heightened risk. Surfaces such as handrails, door handles, and tool grips can also benefit from a non slip paint. Here we will provide you with all the information you need to determine which anti slip coating solution is right for your project, and help you find the anti slip product you need.

3 factors that affect the choice of anti slip paint

How you choose your non slip coating depends upon a number of factors. Anti slip paints are numerous, and many are intended for specific substrates or end uses. When choosing your paint therefore, it is paramount that you keep in mind:

anti slip paint applied in tunnel and stairs

Anti slip paint is common in public places; hallways and stairs.

  1. Your substrate type: metal, concrete, wood, plastic, etc. (see below)
  2. Your substrate’s environment: Is there a risk of chemical exposure, abrasion, UV radiation?
  3. The intended end use: Will it need to withstand mechanical loads and heavy impacts, or is it for foot traffic? Is it in a setting where health and cleanliness is a concern?

Metal: the anti slip coating for metal substrates for instance, needs to be anti corrosive as well.
Wood: coatings for wooden substrates also need to be resistant to alga formation.
Concrete: If the coating gets applied to concrete, the coating will use the concrete’s own structure to make it anti slip.

Choose the right type of anti slip coating for your needs

Once you know exactly what you need from your coating, you need to understand the demands of each coating type. Anti slip coating comes in three different types: as a separate paint and non slip additive which need to be combined, a premixed coating, and as a nano coating.

Make any coating anti slip with an additive

What it is: Anti slip properties are given to a coating by adding an aggregate such as sand, glass beads, rubber crumb, and others. The aggregate provides a rough surface which prevents slipping. Aggregate can be mixed through a coating before application, or sprinkled over a still wet first coat. If the second, it should be allowed to dry before having excess aggregate brushed away and a second coat applied on top. The aggregate comes in three grades: fine, medium, and coarse, in order of increasing anti slip strength.

Suitable substrates: All, just choose your coating and aggregate pairing carefully.

Where to apply:  Heavy industrial-use flooring to kitchen floors, aggregate is a flexible material. However, which aggregate you choose will affect which coating you can use: glass beads and synthetic aggregate can be combined with acrylic coatings as well as resin coatings (epoxy, urethane, polyaspartic and polyurea), whereas silica sand, aluminium oxide, coloured quartz and flint silica aggregates can only be used with resin coatings. However, adding your own aggregate gives you control over the result.

Benefit from the anti slip properties of invisible nano products

What it is: An anti slip paint based on nanotechnology uses the numerous benefits of nano coatings and adds one more by making them non slip, too. A relatively new process, the non slip coating with nanotechnology provides a textured surface on a scale so small it is virtually unnoticeable, but which actually becomes even more anti slip when it is wet. These coatings are also durable, waterproof, abrasion resistant, long-lasting, low-maintenance, and non-toxic.

Suitable substrates:All.

Where to apply: Applications which require a clear, glossy finish and very thin coating profile. Nano non slip coatings can be used for interior and exterior applications including entryways and ramps, in food preparation areas, in wet-prone areas like spas, swimming pools, and leisure centres.

Get a premixed anti slip paint for easy application

What it is:The simplest of the non slip coatings, these products come with aggregate pre-mixed, either as a two- or single-component rubberised paint systems, or create a rough textured surface as the coating dries. These coatings are durable, water and oil resistant, and come in epoxy, polyurethane varieties. They are often divided into categories based on specific need; Offshore (corrosion resistant non slip paint for metal surfaces), Industrial (chemical and abrasion resistant coatings) and Commercial (aesthetically appealing non slip coatings).

Suitable substrates: There are specific products for specific substrates; this option is suitable for all substrates, but you need to choose the appropriate coating. For a breakdown of anti slip coatings by substrate, visit our anti slip pages for concrete, wood, and metal.

Where to apply: Interior and exterior floors, walkways, decks, patios, mild industrial and commercial environments with up to heavy pedestrian foot traffic and light rubber wheeled cart traffic. Hospitals, kitchens, change rooms, schools, anywhere that requires a non slip floor paint.

Pendulum testing defines the required slip resistance of floors and anti slip paint

The slip resistance of flooring needs to comply with specific standards and an anti slip paint can help achieve the certain level of resistance. The Hong Kong Workplace health, safety and welfare regulation 1992 states that ‘a floor shall not be slippery’. In Hong Kong one of the most common tools to define ‘slippery’ is standard defined by Pendulum Testing. This is a test method that measures coefficient of friction and mimics a heel slipping on a floor. The test results in exact Pendulum Test Values, also known as PTVs. Here below you can find the PTVs and associated slip risk indications.

  • PTV 36+, low slip risk: a 1 in a million slip probability
  • PTV 25-35, moderate slip risk: 1 in 200 slip probability
  • PTV 0-24, high slip risk: 1 in 2 slip probability (PTV 20)
