Specification

The information contained in this product data sheet is typical but does not constitute a full specification as conditions and specific requirements may vary from project to project. The instructions should be considered as a minimum requirement but the applicator or contractor must use their skill, knowledge and experience to carry out additional works as may be necessary to meet the requirements of the project. Specification for specific projects should be sought from the Company in writing.

Limitations

» 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. Chemicals spills must be cleaned immediately.
»The manner in which the product is applied will affect the degree of 'anti-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.
» Colours will lighten and yellow over time.
Shelf Life: 6 months in unopened containers, store in cool and dry conditions.

Benefits and Advantages

• Single pack - no mixing is required. Takes the stress and difficulties away from using two part systems.
• Brush, roller or spray applied.
• Quick curing - generally overnight.
• Tough, durable & flexible.
• Impact & vibration resistant. It is not brittle like some epoxies.
• Odourless when cured.
• Suitable for light to medium duty traffic.
• Easily overcoated & repaired.
• Good chemical  resistance - but refer 'Clean-Up'.
• Attractive finish 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 and adequate ventilation should be provided. In confined areas 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. Vapors 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 Surface Preparation

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

 

Concrete & Porous Tiles
Surface must be porous to allow the product to bond. The surface should be tested for porosity by spilling droplets of water on 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 includes, steel troweled & 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 one good coat of either Duram Primeseal (2 part water based primer/sealer) at the rate of 3m² to 4m² per coat ensuring that the  the coating has a solid, off-white appearance. 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 at 3m2 per Litre. 

Metal
Bare metal must be treated for rust & then etch primed. Apply Rocktuff as soon as possible after etched primer has fully cured  and before any surface contamination occurs.

Painted Surfaces
This generally applies to painted vehicles, equipment & 'Colorbond' type coated metal. Test surfaces with Duram Solvent for softening. If paint is effected 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 and then clean.

Fibreglass
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 Duram Primeseal ensuring it has fully cured before the application of Rocktuff.


Application

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

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

By Spray
Mask off areas not intended to be coated. If required, Rocktuff may be diluted  by adding up to 10% (max.) with Duram Solvent and thoroughly mix slowly. Spray via a panel beater type gun at approx. 80 psi (5.5 bar) or airless spray with 30 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 microns 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 and 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 and apply the new coat/s of Rocktuff.
• Remove any damaged or loose areas.
• Clean and roughen surface as well as surrounding Rocktuff.
• Treat exposed areas as per preparation instructions.
• Apply new Rocktuff to area including 20 mm onto the existing sound Rocktuff coating.

Coverage

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 2m² per Litre per coat applied in 2 or 3 coats.
Additional coats maybe applied for heavier traffic.

Colours

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