Why Slip Resistance Matters for Line Marking
Quick answer: Slip resistance ratings come from AS 4586:2013, which rates new floor surfaces with P ratings (P0 to P5, wet pendulum test) and R ratings (R9 to R13, oil-wet ramp test). Line Marking Australia picks line marking paint and anti-slip finishes to match each area, for example P4 for wet wash-down zones, so markings never create a new slip hazard.
Most people don't think about slip resistance when they think about line marking. But paint changes the surface characteristics of your floor. Apply the wrong product and you can create a slip hazard where none existed before.
AS 4586 classifies floors by slip resistance using P ratings (pendulum test, wet) and R ratings (ramp test, oil). Different areas need different ratings. A dry warehouse aisle has different requirements than a wet processing area.
We received a callback from a food processing plant in Laverton where staff were slipping on newly marked pedestrian lanes. The paint we'd used was fine for dry conditions but became slippery when wet from their regular wash-down.
We returned and applied anti-slip aggregate to the pedestrian lanes, bringing them up to P4 rating suitable for wet conditions. Now we always confirm the expected conditions before selecting materials.
Testing existing floors
New products are rated under AS 4586:2013. Floors already in use are tested on site under AS 4663:2013. If your markings need more grip, see our slip-resistant coatings, anti-slip stair nosings and warehouse walkway marking pages.

Frequently Asked Questions
P3 is suitable for dry internal areas. P4 for areas that may get wet occasionally. P5 for areas that are frequently wet. We help determine the appropriate rating for each area of your facility.
P ratings (pendulum test) measure slip resistance on wet surfaces. R ratings (ramp test) measure slip resistance in oily conditions wearing footwear. Different tests for different hazards.
Yes, paint changes surface characteristics. Standard paint can reduce slip resistance on some surfaces. Anti-slip additives can increase slip resistance where needed.
Yes, we can arrange pendulum testing to verify slip resistance ratings after line marking application. This provides documented evidence of compliance.
We can apply anti-slip aggregates or coatings over existing marking to increase slip resistance. Or remark with appropriate anti-slip materials.
Slightly, due to aggregate additives. But this is minimal compared to the cost of a slip injury. We recommend anti-slip materials for any area that may get wet.
