Anti-slip coating for natural stone protects sandstone, bluestone limestone and granite from acid damage while achieving CSIRO-certified slip ratings for Australian conditions. Stellmann adjusts application for each stone type's unique porosity, unlike competitors who use a one-size-fits-all approach. Suitable for outdoor pavers, pool surrounds pathways and commercial stone surfaces.
What sets Stellmann apart: Porosity-adjusted for each stone type. competitors use one-size-fits-all.
Whether you’re a facility manager responsible for slip compliance across commercial natural stone surfaces, or a homeowner looking for a reliable professional anti-slip service. Stellmann has you covered. Our CSIRO-certified coating is available as a professional done-for-you service.
Done-For-You Professional Service

HOW IT WORKS
We identify your stone type (bluestone, granite, sandstone, limestone) and assess porosity, finish (honed, bush-hammered, polished) and current condition. A pH-neutral, stone-type-appropriate clean prepares the surface without compromising the natural finish, ensuring optimal coating adhesion specific to that stone's chemistry.
Usually completed within 48 hours
Our dual-component polyurethane coating is applied using techniques adjusted for your stone's specific porosity, deeper bonding for porous sandstone, minimal penetration for dense granite, and balanced application for bluestone and limestone. This customization ensures consistent grip without over-etching dense stone or under-treating porous varieties.
Zero downtime for your facility
Your treated natural stone surfaces receive a documented P-rating (P3, P4, or P5) compliant with AS 4586. You get a certificate of compliance reducing your slip liability and giving you peace of mind. P-rating certificate. Warranty included.
Backed by our Slip-Test Pass Guarantee. Terms & Conditions Apply.
WHY STELLMANN
Every benefit below addresses the specific challenges facing natural stone surfaces. This isn't a one-size-fits-all product.
Customized for bluestone, granite sandstone, limestone and each stone's unique characteristics
Safe for all natural stone types without surface degradation or discolouration
AS 4586 compliant with proven P3/P4/P5 performance on natural stone
Essential for outdoor pavers, pool surrounds and exposed pathways
Competitors ignore stone porosity; we customize every application
Outperforms acid treatments on natural stone by years
No darkening, no clouding, no aesthetic compromise
Most anti-slip treatments for natural stone rely on acid etching, a process that chemically attacks the surface to create texture. While this adds temporary grip, it permanently damages the finish, voids warranties, and typically degrades within 6-12 months.
Stellmann takes a fundamentally different approach. Our dual-component polyurethane coating bonds to the natural stone surface, creating certified slip resistance without any chemical damage to the substrate. Porosity-adjusted for each stone type, competitors use one-size-fits-all
The result: you get documented P-ratings compliant with AS 4586, a surface that looks exactly as it did before treatment, and performance that lasts years, not months. Whether you choose our professional service delivers the same certified technology protects your natural stone.
Stellmann’s anti-slip coating for natural stone is designed for anyone responsible for slip-safe surfaces in commercial, residential, or industrial environments.
Key decision makers include: Landscapers, property developers, patio owners, commercial property developers, and outdoor venue managers.
Whether you manage a single property or a portfolio of sites, Stellmann provides the documentation, certification, and long-term performance you need to reduce liability and maintain compliance.

TRUSTED RESULTS
COMMON QUESTIONS
Straight answers from people who've treated natural stone surfaces across Australia.
Natural stones vary dramatically in porosity, granite is dense requiring minimal penetration; sandstone is highly porous requiring deeper bonding; bluestone and limestone fall between extremes. Stellmann customizes application depth and method for each stone's specific porosity to ensure consistent grip without over-etching or under-treating.
Bluestone is significantly more porous than granite, requiring deeper bonding to achieve slip resistance without surface damage. Granite's density requires careful application to avoid over-etching. Stellmann adjusts application for each stone's specific characteristics.
No. Stellmann's coating preserves sandstone's porous aesthetic while adding slip resistance through bonding, not etching. The stone's natural colour, texture and appearance remain authentic and unchanged.
Yes. Our UV-resistant formulation is specifically engineered for outdoor stone exposure in Australian climates, including coastal limestone areas. The coating protects limestone structure while delivering lasting slip resistance in wet conditions.
