Drying and Curing  

Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing can only be given as a guide.  

Suitable Surfaces    

Virotuff is suitable for most properly prepared and primed and generally porous substrates including:

Porous concrete, cement render, cementitious levelling compounds, brick, block work, masonry, timber including plywoord and particle board, FC and CFC sheeting, porous tiles (excluding vitrified, non-porous and glazed tiles), metal etch primed metal, soundly painted surfaces and fibreglass.

Apply test areas to all surfaces and in particular doubtful surfaces.     

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    

1. Virotuff relies on the texture of the aggregate bound within the coat. 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.

2. Virotuff should be regarded as a general purpose anti-slip coating and is not intended for areas demanding high anti-slip such as wet ramps, fat or oil build up, slippery foot wear. Test areas should be applied and tested. The Company makes no claim as to the suitability of the product for these areas and user assumes all risk.

3. It is essential that the product be kept clean and free of dirt and grime build-up. Chemical spills must be cleaned immediately.

4. The manner in which the product is applied will affect the degree of 'anti-slip'. Further, applied with a roller or applied too thick or patchy will reduce the ant-slip properties.

5. The product must not be regarded as a waterproofing membrane but can be used as a trafficable top coat over water based waterproofing membranes such as Azcoflex and Fibrecryl.

6. Virotuff is semi-flexible and may not bridge live cracks, expansion joints, joins and gaps.

7. Virotuff, being a trafficable floor coating, is subject to wear and tear and its effective life is subject to its use and abuse. It should be periodically inspected to assess its functionality and if required recoated.

Precautions in Use     

Virotuff is water-based and considered as a non hazardous product. However, when using the product common sense and good industrial hygiene should be observed. The use of gloves and eye protection against splashes is recommended. If spraying, a dust mask and goggles should be worn.  

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.      

Surfaces must be clean and dry. It is vital that all contaminants, particularly oils, grease, waxes, acids and corrosive contaminants are removed which may require cleansing with strong detergents, high pressure cleaning, acid wash or other to ready the surface for application.  

After surface is made good with preparation , prime all surfaces with Primeseal MC at the minimum rate of 4 sqm per litre per coat and allow to dry. Highly porous or friable surface may require an additional coat of Primeseal MC. Note: In ideal conditions, the product may be used without a primer but it is this Company's recommendation that all areas be primed and if not primed it is at the risk of the user. Test areas are recommended.  

Concrete, Cement & 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 prompt 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 doubtful surfaces includes, steel trowelled, smooth, glassy or shiny or 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 deemed suitable, apply a priming coat of Primesea MC so that the surface has a uniform, solid  off-white appearance and allow to dry.

In exposed areas where entrapped water moisture may exist in the substrate (which can lead to bubbling) the surface must be primed with Primeseal MC applied 3 sqm per litre.  

Metal:

Bare metal must be treated for rust then etch primed and allowed to dry.  

Painted Surfaces( inclusive of vehicle paint, powder coats and baked-on enamels):

Paint should be of good quality and must be firmly bonded to the substrate. Roughen with sandpaper or wire brush ensuring gloss is removed. Clean or wipe with Solvent allow to dry and apply Virotuff. If painted surface softens on contact with Solvent do not continue. Allow paint to dry and harden and prime with Primeseal MC. Allow to dry and then apply Virotuff.  

Fibreglass:

Sand to remove all gloss & clean with Solvent. When dry, prime with Primeseal MC. Generally, Virotuff can be applied directly to the prepared fibreglass but not advisable. Test areas should be done.  

Timber & Fibre-Cement Sheeting:

Sand or wire brush then clean. Prime with Primeseal MC.  

Bitumen

Clean surface and apply Primeseal MC ensuring that the surface has a solid, uniform off-white colour. If in doubt apply a second coat.  

Application    

Stir thoroughly before starting the application process, then intermittently.  

Apply by brush or suitable roller (black or medium texture) in coats of approximately 500 micons thick (0.5mm) until desired thickness is achieved. Rolling then lightly brushing with a soft broom is an easy way to give a good result. Rolling alone is not encouraged to uniformly disperse the aggregate. It is important that the product's texturing is maintained with each coat. Coats applied too thickly can cause unsatisfactory results. Spread onto surface as evenly as possible. Subsequent coats should be applied at right angles to the previous coats. Apply following coats as soon as possible after previous coat has dried.  

By Spray

Mask off areas not intended to be coated. Usually sprayed without dilution but if required Virotuff can be diluted with clean water up to a maximum of 5% by volume. Suitable spraying techniques is via panel beater type gun, hopper gun or airless spray. General recommendation, spray at lowest practical pressure possible.

By panel beater type gun and hopper gun - at approx. 80 psi (5.5 bar)

By airless spray with 32 to 35 thou tip at 1000 to 2000 psi. Remove all filters in up-take pipe and in the gun.

Spray at approximately 500 micons thick per coat. 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 previous coat is dry. To achieve best results, masking tape, if used, should be removed after each coat when still wet. After spraying, immediately clean equipment with water.  

Irrespective of application the dry coat thickness should be approximately 1mm.  

Wear, Tear & Repair of Virotuff.

Although Virotuff 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.  

To apply a maintenance or rejuvenation coat, clean surface, wire brush, wipe with Prep Solvent or MEK and allow solvent to evaporate. Then apply new coat/s of Virotuff as follows:

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

Coverage   

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

Virotuff: 2m2 to 2.25m2 per litre per coat applied in minimum of 2 coats. Heavy duty areas should receive additional coat/s. On average the total coverage of a 15 litre pails is 15m2 to 18m2.

Primeseal MC: Minimum of 1 litre per 4m2 per coat.          

Indicative curing rates at 23 oC at 50% R.H.@ 500 micron thick:

Touch dry: 2 to 6 hours.

Solid Cure: 6 to 24 hours. Recoat after solid cure ensuring previous coat can be walked on without damaging it.

Full Cure: 24 to 72 hours.

The product is suitable for light loads after 36 hours & full load after 72 hours. The product attains full properties after 72 to 168 hours (3 to 7 days) .

If exposed, do not apply if rain is imminent. Coatings must be protected from water until fully cured.  

Storage  

Keep in cool, dry place, out of direct sunlight. Available in 1, 4 & 15 Pails. Store in original labelled containers. Product is not flammable.    

Clean Up    

Avoid spills. They are difficult to clean particularly off porous surfaces. For wet spills use an absorbent cloth and water. Equipment should be immediately cleaned with water. Ensure product does not enter drains or waterways.  

Tiling, Topping or Top Coating N/A    

Safety & Precautions    

Virotuff is considered a non hazardous product but common sense and good industrial hygiene should prevail. If spraying, the use of a suitable mask is recommended. If swallowed do not induce vomiting, give plenty of water to drink. Seek urgent medical advice. If in eyes, flush thoroughly with clean water, holding lid open to ensure any trapped product may be flushed away. If on skin, remove contaminated clothing and wash skin with soap and water. If inhaled, unlikely due to viscosity of the product, remove person to fresh air and apply artificial respiration if required and seek urgent medical attention. Ensure adequate ventilation.      

For full safety data refer to the products Material Safety Data Sheet. Observe precautions as per label.
