What is AS 4586?
AS 4586 is the Australian Standard slip test: the surface is tested wet and given a P rating from P0 to P5, and the higher the number, the more slip resistance it has.
Why Patios Are a High-Risk Slip Zone
Wet Tiles, Algae and Pool Splash: The Most Common Outdoor Slip Surface in Australian Homes and Venues
Outdoor entertaining areas collect everything that makes floors slippery: rain, dew, algae in shaded corners, food and drink. Falls are already Australia’s leading cause of injury hospitalisation (AIHW, Injury in Australia 2024-25); a wet patio during a party is a very ordinary way to join that statistic.
Homeowner
A homeowner’s paved entertaining area turns treacherous after rain, and a dinner-party guest nearly goes down carrying plates.
Hospitality Venue
A cafe closes its outdoor dining area in wet weather because the floor is a liability, and loses the revenue with it.
Retirement Village
A retirement village’s communal patio grows algae each winter and residents stop using it.
Resort
A resort’s patio coating has faded and lost grip after two summers of UV.
Every one of these is avoidable. Stellmann's coating reduces the slip risk and documents it, while keeping the look of the patio you already have.
How it works
Treat Once, Entertain All Year
The process is the same whether you are treating a 30 m² home patio or a 500 m² resort pool deck.
1
Profile
Call or send an enquiry. We assess the patio first: surface, sun and water exposure. Then we match the right Stellmann product, with P4 as the outdoor target. On-site assessment and slip testing can be arranged for venues and communal areas.
2
Treat
Certified installers coat the area, or DIYers roll on a kit over a weekend. No acid, no etching, no grinding. Cured and walk-ready in up to 12 hours.
3
Verify
Treated areas are certified to AS 4586 P4 at the time of treatment and testing. Professional jobs carry the FEEL-THE-GRIP GUARANTEE* (terms and conditions apply).
4
Maintain
Maintenance guide plus re-test recommendations, because outdoor grip is seasonal work: algae comes back every winter.
MULTI-SURFACE COMPATIBLE
Patio Surfaces We Treat
Patio mix materials, and each one slips differently. Stellmann's coating is tested and rated across all the common ones.

Hospitality Duty Of Care
Cafes, restaurants and venues with outdoor dining must keep guest floors safe. Documented grip reduces public liability exposure.

Questions, answered
Patio Coating FAQs
Will the coating change how my pavers or tiles look?
The finish is nearly invisible. Decorative pavers, stone and tiles keep their colour, they just grip when wet.
What rating does a patio need?
P4 under AS 4586 for outdoor areas. Covered alfresco zones that stay dry may be treated differently; your free product match will specify per zone.
Can I apply it myself?
Yes. Home patios are a realistic DIY weekend job with the roll-on kit. Venues and communal areas should use the professional service for certification and the FEEL-THE-GRIP GUARANTEE* (terms and conditions apply).
When can we use the patio again?
Treated areas are cured in 12 hours. Full furniture-back-on cure times are in the product instructions and your free product match.
Does the coating change how a gloss tile looks?
On a gloss tile the sheen can change slightly toward satin; that is the only visible difference most customers notice.
