Extreme Anti-Slip Step Paint is a high-performance, water-based acrylic coating formulated to provide durable, long-lasting slip resistance on steps, stairways, and high-risk pedestrian access areas. Designed for both internal and external use, it delivers a tough, textured finish that significantly improves underfoot grip in wet, damp, or heavily trafficked environments while maintaining a clean, professional appearance.

This specialist coating is ideal for improving safety across a wide range of commercial, industrial, and residential settings where slip hazards are a concern. The advanced acrylic formulation incorporates silica grit aggregates that create a consistent, textured surface profile, reducing the risk of slips and falls without being overly abrasive. Its low-odour, water-based composition allows for safe use in occupied buildings, including schools, hospitals, warehouses, offices, and public access facilities where minimal disruption is essential.

Available in a wide range of highly visible, fade-resistant colours including Charcoal, Mid Grey, Light Grey, Black, White, Red, Mid Green, Dark Green, Light Blue, Dark Blue, Sandstone, Brown, Terracotta, and Mid Blue. The UV-stable pigments ensure colour retention over time, preventing fading in outdoor environments exposed to sunlight and weathering. The colour range makes it suitable for safety marking, edge highlighting, and compliance with workplace safety standards on stair edges, landings, and access platforms.

Manufactured in the UK. This coating provides consistent performance and reliability across all applications. Its breathable film technology allows moisture trapped in the substrate to escape while still sealing the surface, reducing blistering, peeling, and common coating failures. The flexible coating film accommodates minor substrate movement, helping to prevent cracking on stair edges and high-stress areas. The quick-drying formulation enables fast return to service, making it particularly suitable for maintenance work in busy facilities where downtime must be kept to a minimum.

Suitable Surfaces:

  • Concrete steps, staircases, and landings

  • Concrete slabs and screeds on access platforms

  • Masonry steps, brick, and stone surfaces

  • Render and screeded stairways

  • Previously painted steps in sound and stable condition

  • Internal and external pedestrian access areas

Note: Not recommended for asphalt, self-levelling screeds, natural stone with protruding aggregate, or highly polished surfaces without proper mechanical preparation. For timber or metal steps, a compatible primer is recommended before application. Always test on a small inconspicuous area before full application. Surface condition, porosity, and existing coatings will influence final appearance and adhesion.

Coverage & Spread Rate:

  • 6–8 m² per litre per coat, depending on surface porosity and profile

  • 5 L tin covers approximately 15–20 m² with two coats

  • 10 L tin covers approximately 30–40 m² with two coats

  • 20 L tin covers up to 65 m² with two coats

  • 1000 L IBC tank covers up to 3,250 m² with two coats — ideal for large commercial, industrial, and institutional projects

Coverage varies depending on substrate porosity and application method. Rough or heavily worn surfaces will require more product. Avoid over-application as this can affect texture consistency and drying.

Drying & Curing Times (@ 18 °C):

  • Touch dry: 1–2 hours

  • Recoat: 2–4 hours

  • Light foot traffic: 12 hours

  • Normal pedestrian use: 24–48 hours

  • Full cure and weather resistance: 7 days

Drying times may vary in cold, damp, or humid conditions. Do not apply if rain is expected within 2 hours for external applications.

Storage & Clean-Up:

  • Store sealed containers between 5–30 °C in a dry, frost-free place

  • Ready to use — thin only if spraying (maximum 5% clean water)

  • Over-thinning reduces film build and slip resistance

  • Reseal firmly between uses to prevent skinning or contamination

  • For 1000 L IBC orders, ensure the tank is stored on a level, stable surface and agitated thoroughly before dispensing to maintain pigment and aggregate consistency

  • Clean tools immediately with clean water after use

  • Dispose of waste in accordance with local regulations

Finish & Appearance:

Leaves a durable, textured satin finish designed to maximise slip resistance while maintaining a neat and uniform appearance. The anti-slip profile is evenly distributed across the surface to provide consistent grip on stair treads, landings, and access platforms. Colour options enhance visibility and improve safety awareness in hazardous areas, with high-contrast shades ideal for edge marking and step nosings.

Safety Notice:

This is a water-based coating with low hazard during application. Use appropriate PPE including gloves and eye protection. Ensure adequate ventilation during indoor use. Avoid eye contact and prolonged skin exposure. Keep out of reach of children and pets until fully cured. Not suitable for ingestion. Refer to the Safety Data Sheet (SDS) for full safety guidance.

Additional Notes:

Available in 5 L, 10 L, 20 L tins, and 1000 L IBC tanks to suit projects of every scale — from single staircase refurbishments to large commercial, institutional, and industrial safety upgrade contracts. For best colour consistency across large areas, order all required material from a single batch. Products may occasionally be supplied in plain or trade-labelled packaging during high demand periods, without affecting performance or specification. Minor packaging imperfections may occur during transit — please do not order if this would be unsatisfactory.

Extreme Anti-Slip Step Paint is designed for use on steps, staircases, and pedestrian access areas where improved grip and safety are essential. It is widely used in:

  • Commercial buildings, offices, and retail premises
  • Warehouses, factories, and industrial facilities
  • Schools, colleges, hospitals, and public institutions
  • Public walkways, communal stairways, and access platforms
  • Fire escapes, emergency exits, and external staircases
  • Residential properties, garden steps, and entrance stairs

The coating is suitable for both indoor and outdoor environments, providing reliable performance under regular foot traffic and varying weather conditions while improving visibility on high-risk surfaces.

Application Instructions

Surface Preparation

Ensure all surfaces are clean, dry, and free from dust, grease, oil, algae, moss, and loose material. Sweep or vacuum thoroughly before application. For external steps and staircases, pressure wash if required and allow to fully dry. Remove any flaking paint, chalking layers, or unstable coatings by scraping or sanding, and feather edges smooth. Repair cracks or damaged areas with a compatible repair mortar and allow repairs to cure before painting.

Priming

Priming is not typically required on sound, prepared surfaces. On highly porous concrete, masonry, or screeded substrates, apply a diluted first coat using up to 10% clean water to improve penetration and adhesion. Allow the primer coat to dry fully before applying subsequent coats. For timber or metal steps, a compatible primer is recommended to ensure long-term adhesion.

Mixing

Stir thoroughly for at least 2 minutes using a paddle mixer or broad flat stirrer before use to ensure even distribution of the anti-slip silica grit aggregates. Continue to stir occasionally during application to maintain consistency. The product is supplied ready for use — do not over-thin, as this will reduce slip resistance and film build.

First Coat

Apply using a brush or medium-nap roller. Spread evenly across the step surface ensuring full coverage without excessive build-up. For spray application, thin with a maximum of 5% clean water to achieve optimal spray viscosity. Work methodically along treads, risers, and landings to maintain a consistent textured finish. Pay particular attention to step nosings, edges, and high-wear areas. Allow 2–4 hours drying time before recoating.

Second Coat

Apply the second coat at right angles to the first to ensure uniform coverage and consistent anti-slip texture. Work systematically across all treads, risers, and landings, checking for missed areas or thin spots. This coat enhances durability and slip resistance, locking in the silica grit for long-term performance under regular foot traffic.

Optional Third Coat

For high-traffic areas such as public stairways, industrial access points, fire escapes, or external steps exposed to heavy weathering, a third coat may be applied after the second coat has fully dried. This provides maximum film build, extended service life, and enhanced grip on critical safety surfaces.

Curing & Reopening Times

  • Light foot traffic after 12 hours
  • Normal pedestrian use after 24–48 hours, depending on conditions
  • Full cure and weather resistance achieved after 7 days

Avoid heavy rain, standing water, or aggressive cleaning during the first 48 hours after the final coat to allow the film to develop full strength.

Pro Tips

  • Apply during dry conditions with temperatures between 10–25 °C.
  • Avoid application in extreme temperatures, direct intense sunlight, or high humidity.
  • Do not apply to damp surfaces or if rain is forecast within 2 hours.
  • Use masking tape for clean edges on step nosings and edge markings — remove while the coating is still slightly tacky for a sharp finish.
  • Work in manageable sections to maintain a wet edge and avoid lap marks.
  • For multi-flight staircases, apply coats in sequence to maintain colour and texture consistency across all steps.
  • Consider using a contrasting colour on step nosings for improved visibility and compliance with safety standards.

Clean-Up

Clean all brushes, rollers, and spray equipment immediately after use with clean water. For dried residues, use warm soapy water. Reseal containers firmly to prevent skinning. Dispose of waste materials and empty containers responsibly in accordance with local environmental regulations. Do not pour residues into drains or watercourses.

Frequently Asked Questions

What surfaces can I apply Anti-Slip Decking Paint to?
Anti-Slip Decking Paint is designed for exterior timber decking (softwood and hardwood) but also performs well on plywood, concrete, stone, garden steps, ramps, patios, jetties, and balconies. For best results, the surface must be clean, dry, structurally sound, and free from loose material before application.
Can Anti-Slip Decking Paint be used outdoors in all weather?
Yes, this product is fully UV and weather resistant, formulated to withstand rain, frost, and prolonged sun exposure without cracking, peeling, or fading. For best results, apply in dry conditions between 10°C and 25°C and avoid rainfall for at least 6 hours after application.
Does Anti-Slip Decking Paint provide anti-slip protection?
Yes, this anti-slip decking paint contains a fine textured grit additive that creates a high-friction, slip-resistant surface once cured. It is ideal for wet, mossy, shaded, or high-traffic areas and maintains grip even when wet.
How does Anti-Slip Decking Paint compare to decking oil?
Decking oil penetrates timber and requires frequent reapplication, while this product forms a durable protective coating on the surface. It offers longer-lasting colour, stronger UV protection, and enhanced anti-slip performance compared to traditional oils.
What’s the expected lifespan of Anti-Slip Decking Paint in UK climate?
With proper preparation and a two-coat application, this decking paint typically lasts 5–7 years on vertical surfaces and 3–5 years on high-traffic horizontal areas. Maintenance coats can extend its durability further.
Is primer needed before applying Anti-Slip Decking Paint to timber?
A separate primer is not usually required as this product is self-priming. On bare or porous timber, a thinned first coat can improve adhesion and sealing.
Does Anti-Slip Decking Paint need a primer on bare pine, cedar, or hardwood?
Softwoods like pine and cedar benefit from a thinned first coat for even sealing, while hardwoods can usually be painted directly after proper cleaning and degreasing.
How many coats of Anti-Slip Decking Paint are recommended for best results?
