Extreme Anti-Slip Step Paint 5.0 kg

Q: What surfaces can I apply Extreme Anti-Slip Step Paint to?

Extreme Anti-Slip Step Paint is designed for concrete steps, staircases and landings, concrete slabs and screeds on access platforms, masonry, brick and stone surfaces, render and screeded stairways, and previously painted steps in sound condition. It is suitable for both internal and external pedestrian access areas, provided the surface is clean, dry and structurally sound.

Q: Are there any surfaces Extreme Anti-Slip Step Paint should not be used on?

It is 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 should be applied first, and a small test area is always advised before full application.

Q: Can Extreme Anti-Slip Step Paint be used indoors as well as outdoors?

Yes, it is formulated for both interior and exterior steps and staircases. Its low-odour, water-based composition makes it safe for occupied buildings such as schools, hospitals, warehouses, offices and public access facilities where disruption must be kept to a minimum.

Q: Does Extreme Anti-Slip Step Paint provide genuine slip resistance?

Yes. The product is supplied with a separate silica anti-slip additive that must be mixed completely into the base paint before application, creating a consistent textured surface once cured. It significantly improves underfoot grip in wet, damp or heavily trafficked areas without being overly abrasive.

Q: What colours is Extreme Anti-Slip Step Paint available in?

It is available in Charcoal, Mid Grey, Light Grey, Black, White, Red, Mid Green, Dark Green, Light Blue, Mid Blue, Dark Blue, Sandstone, Brown and Terracotta. The UV-stable pigments resist fading outdoors and the colour range suits safety marking, edge highlighting and step nosings.

Q: How many coats of Extreme Anti-Slip Step Paint are recommended?

Two coats are recommended as standard, with the second applied at right angles to the first for even coverage and consistent texture. A third coat is advised for high-traffic areas such as public stairways, industrial access points, fire escapes and heavily weathered external steps.

Q: How much coverage can I expect per litre of Extreme Anti-Slip Step Paint?

Coverage is approximately 6–8 m² per litre per coat, depending on surface porosity and profile. Rough or heavily worn surfaces will require more product, and over-application should be avoided as it affects texture consistency and drying.

Q: How much area does each tin size of Extreme Anti-Slip Step Paint cover?

A 5L tin covers approximately 30–40 m² per coat or 15–20 m² for two coats; 10L covers 60–80 m² per coat or 30–40 m² for two coats; 20L covers 120–160 m² per coat or 60–80 m² for two coats; and a 1000L IBC covers 6,000–8,000 m² per coat or 3,000–4,000 m² for two coats.

Q: How long does Extreme Anti-Slip Step Paint take to dry?

At 18 °C it is touch dry in 1–2 hours and can be recoated after 2–4 hours. Light foot traffic is possible after 12 hours, normal pedestrian use after 24–48 hours, and full cure with weather resistance is achieved after 7 days.

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

Open the base paint, then add the complete supplied anti-slip silica additive. Mix thoroughly for at least 2 minutes using a paddle mixer or broad flat stirrer until the aggregate is evenly dispersed. Stir occasionally during application to keep the aggregate suspended. Do not over-thin, as this will reduce film build and slip resistance.

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 builds a uniform, long-lasting anti-slip texture for 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.
