Stairways represent a critical risk zone in any facility, with step edges being the primary point where slips and falls initiate. Achieving a safe environment requires more than just a general non-slip treatment; it requires a targeted strategy for the leading edge of each step.
Selecting between anti slip stair nosing, adhesive tapes, and specialised coatings is a decision that impacts not only immediate safety but also long-term maintenance costs and compliance status.
The choice is often dictated by the specific substrate, the volume of foot traffic, and environmental conditions such as exposure to moisture or chemicals. Understanding the trade-offs between these systems ensures that the selected control measure is fit for purpose and provides consistent performance throughout its service life.
Technical Mechanics of Step Edge Traction
The leading edge of a stair tread is the most critical contact point during both ascent and descent. During descent, the heel typically makes initial contact near the edge, requiring immediate friction to prevent a forward slip.
Conversely, during ascent, the forefoot pushes off the edge, necessitating stable grip to avoid a backward slip or trip.
Mechanical Interlock and Material Composition
GRP (glass fibre reinforced polyester) nosings utilise an embedded abrasive grain that creates a physical interlock with footwear. This is a mechanical form of friction where the grain actually bites into the sole of the shoe.
- Matrix Integrity: The abrasive grains are not merely glued to the surface but are embedded within a high-grade polyester resin matrix during the manufacturing process.
- Structural Bridge: Because GRP is a rigid composite, it provides a three-dimensional safety barrier that can bridge minor structural imperfections or chips in the stair itself.
- Impact Resistance: Unlike surface-level treatments, a GRP profile absorbs the energy of footfalls, protecting the underlying substrate from crumbling.
- Luminance Contrast: The “nose” or turndown of a profile serves a vital visual function by clearly defining the boundary of the step, essential for those with vision impairments.
Surface Friction and Chemical Bonds
Adhesive tapes and anti slip coatings work primarily through surface friction. While they do not offer the structural volume of a nosing, they rely on high-performance binders.
- Carrier Films: Tapes use a carrier film, typically PVC or a more flexible foil, coated with minerals like aluminium oxide.
- Resin Binders: Coatings like UVGrip use advanced polymer chains to hold abrasive grains in a suspension that adheres at a molecular level to the substrate.
- Profile Height: Tapes and coatings have a low profile height, meaning they do not change the dimensions of the step, which can be a requirement in heritage-listed buildings where architectural lines must remain unaltered.
- Seamless Application: Coatings provide a continuous barrier that prevents water ingress into porous substrates like concrete or stone.
Selection Criteria and Substrate Compatibility
When evaluating the best approach for stair safety, facility managers must consider the wear zone and the substrate condition. A damaged or rounded concrete edge cannot be easily repaired with tape; it requires the structural bridging provided by a rigid nosing.

Assessing the Environment
The durability of a solution is a primary differentiator in heavy industry and industrial applications.
- Corrosive Resistance: GRP stair nosings are designed to be virtually indestructible, resisting chemicals, UV radiation, and extreme temperatures.
- Offshore Performance: These are often the preferred choice for offshore safety where weather resistance is mandatory and salt-water corrosion is a constant threat.
- Rapid Deployment: In contrast, anti slip tapes are a cost-effective, temporary solution, excellent for low-traffic areas or emergency exit stairs that see infrequent use.
- Hospitality Aesthetics: Coatings offer a seamless look that is ideal for hospitality safety or commercial kitchens, where aesthetics and hygiene are equally important.

Real-World Applications and Environmental Suitability
The environment dictates the technology. In an industrial setting such as a mining site, the presence of oils, greases, and heavy work boots necessitates a heavy-duty GRP solution.
- External Fire Stairs: GRP nosings provide high weather resistance and long-term durability against rain and sun.
- Commercial Kitchens: Seamless coatings are often preferred as they are hygienic, non-porous, and easy to clean without trapping food particles.
- Office Emergency Exits: Standard adhesive tapes offer a rapid and low-cost installation for areas with limited pedestrian load.
- Public Infrastructure: High-visibility nosings are required to handle constant pedestrian loads in train stations and shopping centres.
- Aquatic Centres: Specialised solutions for aquatic centres must resist constant water exposure and chemicals like chlorine.
Installation and Implementation Planning
Successful implementation of stair safety products depends heavily on meticulous surface preparation and choosing the correct fixing method for the specific substrate.
- Surface Assessment: Inspect the stairs for structural integrity. Use a straight edge to check for “cupping” on timber or “rounding” on concrete. Remove any loose debris or failing old paint.
- Substrate Preparation: Ensure the surface is dry and free of oils or chemicals. For tapes and coatings, this step is critical for adhesion. Concrete may require mechanical grinding, while metal may require a solvent wipe.
- Measurement and Cutting: Measure each step individually. Even in modern builds, stairs can vary by several millimetres. GRP nosings should be cut to allow for a 2mm to 3mm expansion gap at either end if used outdoors.
- Dry Fitting: Place the nosing or tape to ensure a flush fit against both the tread and the riser. Check for rocking or instability.
- Fixing Methods: Secure GRP nosings with a combination of high-strength adhesive sealant and mechanical fasteners such as stainless steel screws or rivets. For anti slip products like tapes, apply firm pressure with a seam roller to ensure all air bubbles are removed.
- Curing and Protection: Allow adequate time for any chemical bonds to set. While many GripFactory liquids allow walking within minutes, GRP adhesives typically require 2 to 4 hours to reach the initial set.
Maintenance and Performance Consistency
Maintenance and Performance Consistency
A common failure in facility management is the “install and forget” mentality. Anti-slip surfaces require specific maintenance to remain effective. Dirt and grease can fill the valleys between abrasive grains, effectively reducing the coefficient of friction and increasing the slip risk.
- Cleaning Agents: Use a soap-free cleaner, such as TitaniumGrip Cleaner, to prevent film build-up.
- Mechanical Agitation: For heavily soiled GRP nosings, a stiff deck brush is necessary to dislodge compacted dirt from the abrasive matrix.
- Avoid Waxing: Traditional floor waxes or soapy detergents must be avoided as they create a slippery layer over the grip grains.
- Periodic Inspections: Regularly check for loose fasteners in nosings or lifting edges in tapes.
- Compliance Documentation: For NDIS compliance, these maintenance routines and inspections should be documented to prove ongoing diligence.
Compliance and Safety Responsibilities
In Australia, stair safety is governed by strict standards, including AS 4586:2013 for slip resistance and AS 1428.1 for design and mobility.
For public access stairs, the National Construction Code (NCC) specifies that nosings must provide a certain level of luminance contrast, typically 30 per cent against the background, to assist users with vision impairments.
Document Type | Purpose | Recommended Retention |
Slip Test Report | Verifies the P or R rating of the installed surface | Life of the product |
Maintenance Log | Records cleaning frequency and chemical use | 7 years |
Warranty Certificate | Proof of product durability (e.g., 15-year GRP warranty) | Life of the product |
Inspection Register | Monthly or quarterly safety checks of step edges | 7 years |
Maintaining these records is a critical part of a compliance officer’s responsibilities. In the event of an incident, being able to demonstrate that a compliant product was chosen, professionally installed, and regularly maintained provides a strong defence against liability claims.
Failure to provide adequate protection can result in significant legal costs and increased insurance premiums for commercial spaces.

Anti-Slip Installation & Luminance Contrast FAQs
Adhesion to existing coatings is generally poor unless the surface is mechanically abraded. It is usually more effective to remove the old coating or use a GRP nosing that can be mechanically fixed over the top.
This is achieved by selecting a nosing colour that is significantly lighter or darker than the stair tread. For example, a yellow nosing on a dark grey concrete step usually meets this requirement.
No coating is truly permanent. While highly durable, they are sacrificial layers that wear down over time. Depending on traffic, an anti-slip coating may need a refresh layer every few years to maintain its rated slip resistance.
Yes, GRP nosings are excellent for wood as they protect the timber from edge wear and water ingress. They should be fixed with both a compatible sealant and stainless steel screws.
P-ratings are derived from a Wet Pendulum test, commonly used for pedestrian surfaces. R-ratings come from an Oil-Wet Inclining Platform test, often used for industrial areas where oil contamination is likely.
