Features & Benefits

• May be used as a finishing coat on external flooring requiring a high level of slip-resistance, such as access and exit routes in sports facilities in general (ramps, stairs, etc.)
• The special formulation used enables all the approval and safety standards required by FIA (Federation Internationale de l’Automobile) and FIM (Fédératon Internationale de Motocyclisme) to be met regarding products used to mark out the road surface of motor racing circuits
• Unlike a simple colouring system, allows highly durable, non-slip surfaces to be created that maintain their surface roughness over the years, including in wet conditions
• The mechanical properties of the film, combined with its high resistance to agents potentially harmful for the flooring (such as de-icing salts, oil and fuel, etc.), also make Mapecoat TNS Race Track an excellent solution for coating large surfaces, such as those that need to be treated periodically to prevent ice forming and/or for routine cleaning purposes
• Particularly suitable for protecting substrates: in fact, in the case of concrete flooring, the coloured coating limits the effect of agents that could damage or deteriorate the surface, such as carbon dioxide and moisture, thereby making the structure more durable. From an aesthetic point of view, the wide range of colours available, along with the other shades available using the ColorMap automatic colouring system, means that personalised colours may also be created
• Tested in a Weather-Ometer to simulate severe physical and environmental cycles and is able to resist prolonged exposure to sunlight, particularly ultra-violet rays
• From an application point of view, Mapecoat TNS Race Track technology contains special components in the product that help form a film very quickly, so that surfaces may be opened to foot traffic much sooner (after around 30 minutes in certain conditions) than with traditional acrylic systems

Recommendations

Even though Mapecoat TNS Race Track is watertight, it is not a membrane and must not be considered as a substitute, therefore, for traditional waterproofing products (cementitious-based, bitumen-based or polyurea-based) normally used to waterproof horizontal and vertical surfaces.

If surfaces need waterproofing, it is recommended to contact Rawlins technical on 0113 2455450 (option 2) or send a message to [email protected] prior to applying this coloured finishing product for information on the correct application method. Mapecoat TNS Race Track is compatible with most of MAPEI’s waterproofing systems but always check with Rawlins technical what measures need to be taken before applying the final coating.

Mapecoat TNS Race Track may be applied directly on existing coatings: in such cases the condition of the old finish will need to be checked beforehand, such as bond strength, and the compatibility of the old finish with Mapecoat TNS Race Track by testing it on a small area of the finish. If tests show the old finish is suitable for recoating, the surface must always be prepared adequately by washing it with a degreasing product and by lightly sanding to make the surface as rough as possible before applying Mapecoat TNS Race Track. It is recommended to contact Rawlins technical on 0113 2455450 (option 2) or send a message to [email protected] to check and discuss how to use Mapecoat TNS Race Track correctly, according to local application conditions and type of substrate.

• Do not dilute Mapecoat TNS Race Track with solvent
• Do not apply Mapecoat TNS Race Track directly on dusty, crumbling or weak surfaces
• Do not apply Mapecoat TNS Race Track on substrates with oil or grease stains or with stains in general
• Do not apply Mapecoat TNS Race Track on surfaces with water under counter-pressure. In such cases, the substrate needs to be treated beforehand by employing the most appropriate technical solutions and then checked to make sure Mapecoat TNS Race Track may be applied successfully
• In case of application of Mapecoat TNS Race Track on cementitious substrates, a suitable primer must be used

Application Procedure

Preparation of the substrate

The substrate on which Mapecoat TNS Race Track is to be applied must be compact, strong and flat and have no detached or loose areas. The application surface for the coating in particular must be strong enough to withstand the loads acting on the flooring when in service, particularly surfaces used regularly or only occasionally by vehicles.

New surfaces requiring treatment, or areas patched up with repair mortar, must be well-cured, perfectly clean, compact and dry. The coloured film of Mapecoat TNS Race Track must only be applied on substrates with a level surface. All sharp corners, the edges of steps and fillets must be rounded off.

Taking such precautions during the preparation phase allows its consumption rate per square metre to be kept under control and also prevents unsightly defects forming on the surface. Lastly, to complete preparation of the substrate, before applying Mapecoat TNS Race Track, concrete structures need to be dry before treating them with a suitable adhesion promoter, such as Mapecoat TNS Primer EPW diluted 1 : 0.5 with water. In case of application on concrete substrate, apply a suitable primer on the dry surface to grant the correct adhesion of Mapecoat TNS Race Track.

In case of substrates with residual moisture up to 3% use Mapecoat TNS Primer EPW.

In case of residual moisture between 3 and 6% apply a suitable chemical barrier using Triblock P three-component epoxy cementitious primer. Apply the first coat of Mapecoat TNS Race Track after max. 24 hours from the application of Mapecoat TNS Primer EPW and after max. 36 hours if the chemical barrier with Triblock P has been carried out.

In the case of substrates made from bitumen conglomerate, the surface must be clean, there must be no loose material and there must be no traces of oil, fuel or any other material or substance that could affect the soundness of the substrate.

In the case of particularly deteriorated or dirty areas of asphalt, it may be necessary to remove these areas and then repair them with Mape-Asphalt Repair 0/8 cold-applied reactive asphalt. Then, before applying Mapecoat TNS Race Track, any traces of dust or dirt on the surface must be vacuumed off or removed. Before applying Mapecoat TNS Race Track, substrates made from bitumen conglomerate must be cured and oxidised for at least 15 days.

Preparation of the product

Dilute Mapecoat TNS Race Track with up to 10% of water, depending on the surrounding temperature and the temperature of the substrate. Mix the product well before use with a drill at low-speed, taking care to avoid entraining air into the product.

Application of the product

Mapecoat TNS Race Track may be applied using a traditional roller (type mohair 5). For large surface areas, the coloured coating may be applied more quickly using a HVLP (High Volume Low Pressure) mixed air spray system, membrane spraying system or airspray road-marking machines with variable-flow pump. This system generally involves applying minimum 2 coats of Mapecoat TNS Race Track, waiting 8-12 hours between each coat in normal conditions. As soon as the surfaces have been coated they should be protected from rain to prevent Mapecoat TNS Race Track coming into contact with water during its initial drying phase, otherwise its adhesion and the overall quality of the work may be affected.

Cleaning

Clean tools used to apply the product with water. Once dry, Mapecoat TNS Race Track may only be removed mechanically. Clean all tools and equipment thoroughly immediately after applying the product, particularly spray pumps.

Consumption

The consumption rate of Mapecoat TNS Race Track is heavily influenced by the absorption and roughness of the substrate and by the application method used. For level, even substrates, the average consumption rate for roller-applied product is as follows:

• Bitumen conglomerate (wear layer) - consumption of approx. 0.6-0.8 kg/m² for the first coat and 0.3-0.4 kg/m² for subsequent coats
• Smooth concrete and non-absorbent surfaces - consumption of approx. 0.2-0.4 kg/m² for each coat
• Apply minimum 2 coats

Precautions to be taken during Preparation and Application

• Do not apply Mapecoat TNS Race Track if it is about to rain or in windy weather
• Do not apply on wet surfaces or surfaces still damp after hydro-cleaning: adhesion of the Mapecoat TNS Race Track coating may be affected
• Do not apply if the temperature is lower than +5°C or higher than +35°C. Do not apply if the temperature of the substrate is higher than +50°C. Do not apply if the level of relative humidity is higher than 85%

Application Method for Motor Racing Circuits

When applying the product to mark out the road surface of motor racing circuits the following must be adhered to in order to comply with FIA (Federation Internationale de l’Automobile) and FIM (International Motorcycling Federation) product approval requirements.

Preparation of the product

Mapecoat TNS Race Track may be diluted with up to 10% of water when applied with a synthetic roller or flat brush with natural or synthetic bristles. When applied by spray with variable-flow airspray road-marking machine, a mixed HVLP air system or a diaphragm pump, dilute the product with up to 5% of water, according to the surrounding temperature and the temperature of the substrate. It is recommended to mix the product thoroughly before use with a drill at low-speed to avoid entraining air.

Application of the product

Apply Mapecoat TNS Race Track on concrete or non-absorbent surfaces with traditional tools, such as a flat brush with natural or synthetic bristles (e.g. nylon or polyester). For surfaces in bituminous conglomerate, to mark out surfaces more quickly, apply the coloured finish by spray using an airspray road-marking machine with variable-flow pump, a mixed HVLP (High Volume Low Pressure) air system or a diaphragm pump.
