Slip Resistance


Aquepoxy®- Slip Resistance and certification

Slip resistance is influenced by several factors. The inherent abrasion or “slipperiness” of the flooring surface, by the nature of the likely pedestrian activity, by the type of footware and by the probability and nature of contamination. Thus a floor might be considered to be “non-slip” under dry conditions, but the same floor could pose considerable risk if wet or oily contaminants are present.   
Standards Australia has documented four test methods for the evaluation of slip resistance of flooring systems. AS/NZS 4586: 1999 Slip resistance classification of new pedestrian surface materials describes four methods, one of which, the Oil-wet Ramp Test, is recognized as being the more appropriate for industrial situations.   Handbook 197: 1999, An Introductory Guide to the Slip Resistance of Pedestrian Surface Materials provides useful background information.

In the oil-wet ramp test, a person supported with appropriate harness and wearing standard rubber boots, walks up a ramp coated with the test finish on to which a quantity of a standard motor oil has been applied. The angle of the ramp is increased until the threshold of safe walking is reached.
The Standard defines a set of Slip Hazard Classification Groups (R9 – R13) which reflect the mean acceptance angles determined by the test. Thus a higher ‘R’ number means that safe walking can be carried out at a higher ramp angle. Readers should refer to the relevant Standard for more information.
A German regulation (ZH/1/571), quoted in AS/NZS 4586: 1999, links the R9 - R13 Classification Groups to a wide range of industrial flooring workplace situations. This is summarized in the table below, but a more comprehensive list is included in Handbook 197:1999.

Slip Hazard Classification

Examples of work rooms and work areas


Entry foyers of hotels, offices and public buildings (dry); shopping centres (not food areas); hospitals; supermarket aisles; lift lobbies; interior stairs; canteens; shops; packing areas; operating theatres and other dry health service areas; school areas excluding kitchens, toilets, machine and handicraft areas.


External colonnades, walkways and pedestrian crossings; entry foyers of hotels, offices and public buildings (wet); shopping centre food courts; fast food outlets; shop/supermarket fresh fruit and vegetable areas; toilet facilities; undercover areas in sports stadia; storage areas (food preparation); coffee & tea preparation kitchens; sales areas for unpackaged bakery and cheese product areas; health service areas not covered under R9; garages, car parks; school areas not covered under R9. 


External stairs and stair nosings; aircraft hangars; vehicle repair workshop bays (pits are R12); wet or dry production areas not involving oils and fats; laundries; serving counters for unpackaged meat and vegetables; florists; catering establishments, including washing-up areas; wet sterilizing rooms; beverage bottling plants; chocolate and confectionary plants (excluding sugar and cocoa production areas).  


Production areas involving margarine, cooking oils, milk, butter, cocoa, sugar; meat processing areas (see also R13); vegetable processing; large catering areas; sales areas involving deep-fry and grill equipment; waste-water treatment rooms; fire stations; pickling, cleaning, hardening, galvanizing metal-working areas.


Tanneries; vegetable processing and tinning areas; fish processing and delicatessen production facilities; abattoirs and meat processing areas; cooking oil and fat processing areas.
Aquepoxy® Concrete Floor sealers as supplied and before addition of any Skidbrake aggregate, are designed to meet the requirements of an R9 surface.
A range of aggregate compositions, supplied as Aquepoxy® Skidbrake Additives, increase the slip resistance of Aquepoxy® finishes up to an R12 rating.
Incorporating 2kg of Aquepoxy® Skidbrake Fine (SBF) into 25litres of mixed Aquepoxy® sealer will increase the slip resistance to the R10 Category, as tested and certified by CSIRO Industrial Services; a copy of the test certificate is available on application. This modified composition is used in the top coat only.
To achieve R11 and  R12 ratings, Aquepoxy® Skidbrake Coarse (SBC) is broadcast into the second coat, while wet, at the recommended levels as follows:

          For R11 rating – broadcast SBC @ 0.8-1.0 kgs per 100 mt2;
          For R12 rating – broadcast SBC @ 3.0-3.5 kgs per 100 mt2.
A third and final coat of Aquepoxy® sealer / finish is then applied to seal the aggregate resulting in a durable, hard wearing, low skid surface.
The resistance of all industrial flooring products to pedestrian slippage is an extremely important issue in these increasingly litigious times. Our Technical Service personnel will work together with Specifiers and Applicators to improve safety and minimize the potential for accidents due to slip hazards.
CSIRO test certificates are available on request. Do not hesitate to contact us if further information is required.
