The information contained in this data sheet is general in nature and refers only to the usual use of the product and it should not be construed to be a complete specification. Site conditions vary which may require the use of the products and related products to vary. For specific projects a written specification should be sought from the Company.




ROCKTUFF relies on the texture of the aggregate bound within the tough and abrasion resistant polyurethane resin. Therefore, a build up of fatty or greasy substances and grime will diminish or negate the products effectiveness and it is not recommended that it be used in these areas. It is essential that the product be kept free of dirt build-up. Chemical spills must be cleaned immediately. The manner in which the product is applied will affect the degree of 'non-slip' and possibly its X classification in terms of table 2 of AS/NZS 4586 Wet Pendulum Test. Classification tests were based on brushed samples deemed to be worst case scenario. Roller & spray application are likely to provide a higher classification.


Benefits and Advantages


Single pack - no mixing is required.
Brush, roller or spray applied.
Quick curing - generally overnight.
Tough, durable & flexible.
Impact & vibration resistant.
Odourless when cured.
Suitable in food preparation areas.
Suitable for light to heavy duty traffic.
Easily overcoated & repaired.
Chemical 'splash' resistant.
Attractive in a range of colours.

Precautions in Use


ROCKTUFF should be applied in well ventilated areas. ROCKTUFF is solvent based. The use of solvent resistant gloves & goggles is recommended. Breathing masks are recommended when spraying & adequate ventilation should be provided. In confined areas a breathing apparatus is recommended. ROCKTUFF is flammable. Keep all sources of ignition away from the product & the area in which the product is being applied. Vapours may collect in low lying areas.
If swallowed, do not induce vomiting. Give plenty of water to drink. Seek urgent medical attention.
If on skin, remove contaminated clothing & wash with soap & water. Apply moisturising lotion.
If inhaled (unlikely due to its viscous nature), remove person to fresh air. Apply artificial respiration if required. Inhaled substance is likely to be an aromatic hydrocarbon (solvent/thinners).
Priming and Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of loose, flaking, friable material, dust and substances that may diminish adhesion.


Concrete & Porous Tiles:

Surfaces must be porous to allow the product to bond. The surface should be tested for porosity by spilling droplets of water onto it. The absorption of the droplets is a good indicator of a suitable substrate. If droplets show little sign of being absorbed, the surface should be considered as doubtful for bonding purposes needing additional preparation. Examples of such surfaces include: steel trowelled & smooth helicopter finished concrete. These surfaces must be thoroughly acid etched, washed and neutralised to provide a porous surface. This should be done in accordance with E.P.A. requirements. If acid etching is not sufficient, surfaces may require mechanical abrading or sand blasting.

If concrete is as required above, prime with 1 good coat of either Duram PRIMESEAL (2 part water based primer/sealer) or Duram ROCKTUFF PRIMER applied at the rate of 4 sq. m per litre and allow to dry.

In exposed areas where entrapped water moisture may exist in the substrate (which can lead to bubbling) the surface should be primed with Duram PRIMESEAL applied 3 sq.m per litre. 


Bare metal must be treated for rust & then etch primed. Apply ROCKTUFF as soon as possible after etched primer has fully cured & within 36 hours.

Painted Surfaces:

This generally applies to painted vehicles, equipment & 'Colorbond' type coated metal. Test surfaces with Duram SOLVENT for softening. If paint is affected or likely to peel then DO NOT proceed. Further preparation is required: remove paint, clean and etch prime original surfaces as per priming instructions. High quality paint is generally not affected. Roughen with sandpaper or wire brush & then clean.


Sand to remove all gloss & clean with DURAM SOLVENT. Ensure that there are no traces of release agents, waxes or other production additives. Apply ROCKTUFF direct to the surface.

Timber & Fibre-Cement Sheeting:

Sand or wire brush then clean, apply PRIMESEAL ensuring it has fully cured before the application of ROCKTUFF.



Stir thoroughly before starting the application process, then intermittently, avoiding aeration.

Apply by brush or recommended roller (black texture) in coats of approximately 500 micons thick (0.5mm) until desired thickness is achieved. It is important that the product's texturing is maintained with each coat. If applied too thickly, it can cause unsatisfactory results. Spread onto surface as evenly as possible. Apply following coats as soon as possible and this is best within 48 hours.

By Spray:

Mask off areas not intended to be coated. Dilute product by adding 10% DURAM SOLVENT & thoroughly mix slowly. Spray via a panel beater type gun at approx. 80 psi (5.5 bar) or airless spray with 28 thou to 32 thou tip at 1000 to 2000 psi (pressure should be as low as practical). Remove all filters. Spray in overlapping movements in coats of approx. 500 micons thick. It is important that the product's texture is maintained with each coat. Apply following coats at right angles to preceding cured coats as soon as possible & best within 48 hours. To achieve best results, masking tape, if used, should be removed after each coat when still wet. After spraying, immediately clean equipment with DURAM SOLVENT.

Wear, Tear & Repair of ROCKTUFF.

Although ROCKTUFF is tough and durable the nature of the applications renders it subject to wear & damage. It is important that the coating be monitored for wear and tear and that appropriate maintenance should be carried out to retain the products optimum performance.
This is easy to carry out as follows:
To apply a maintenance or rejuvenation coat, clean surface, wire brush, wipe with DURAM SOLVENT or ROCKTUFF PREP. SOLVENT, allow solvent to evaporate & apply the new coat/s of ROCKTUFF.

1. Remove any damaged or loose areas.
2. Clean & roughen surface as well as surrounding ROCKTUFF.
3. Treat exposed areas as per preparation instructions.
4. Apply new ROCKTUFF to area including 20 mm onto the existing sound ROCKTUFF coating.



The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.


Apply ROCKTUFF at a rate of 1 sq. m per litre per coat. Indicative heavy duty applications include load areas of trucks, utes & trailers, scaffold planks & working platforms or areas subject to high impact, load points, mechanical abrasion or subject to chemical attack. Usage is quoted as the total amount of product required per coat, to be applied in 2 to 3 coats. Additional coats may be applied for heavier traffic.




Colours are available on application. Minimum purchase quantities may apply. NOTE: Whilst every attempt is made to replicate colours, minor batch to batch colour variations may occur so batch lots should be ordered.

Shelf Life: 6 months in unopened containers.
