Mapei Mapecoat TNS Fast

Mapei Mapecoat TNS Fast is an acrylic resin-based, rapid film-forming product with selected fillers in water dispersion and is used to form a durable coating on floors subjected to a high level of footfall and light vehicle traffic.

Best Uses

Mapecoat TNS Fast is an acrylic, resin-based, rapid film-forming product with excellent physical and mechanical characteristics which make it suitable for colouring and protecting concrete and bituminous conglomerate surfaces subject to a high level of footfall. Thanks to the selected fillers used in its special formulation, Mapecoat TNS Fast can be used as a finishing coat on external flooring that needs to have a high level of slip-resistance, such as access floors in public areas. Unlike simple colouring systems, Mapecoat TNS Fast technology creates highly durable, slip-resistant surfaces that maintain their roughness over time, even in wet conditions.

The mechanical properties of the film, combined with its high resistance to chemical products potentially harmful to surfaces (such as de-icing salts, oil and fuel, etc.), make Mapecoat TNS Fast suitable for coating large areas that need to be treated periodically, for example to prevent ice formation and/or for routine cleaning purposes.

Mapei Mapecoat TNS Fast is ideal for:

• Protecting and colouring the surface of concrete in areas subject to a high level of footfall, such as spectator stands in sports facilities
• Protecting and colouring the surface of concrete, decorative concrete and interlocking pavers
• Protecting and colouring bituminous conglomerate surfaces
• Protecting and marking out the surface of access/exit routes in sports facilities, such as ramps and parking areas
• Colouring and protecting concrete architectural elements
• Creation of cycle lanes/tracks and areas subject to light vehicular traffic
• Coating and colouring of outdoor areas subject to heavy foot traffic, even in wet conditions, such as around swimming pools

Mapecoat Fast is 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, combined with the additional shades that can be created using ColorMap® automatic colouring system, makes it possible to create custom colours on demand. Mapecoat TNS Fast, is tested in a Weather-Ometer to simulate severe physical and environmental cycles and is able to resist prolonged exposure to sunlight, particularly ultraviolet rays.

From an application point of view, Mapecoat TNS Fast technology contains special components that film very quickly, allowing surfaces to be opened to foot traffic much sooner (after approx. 30 minutes under certain conditions) than with traditional acrylic systems.

Application

Preparation of the substrate
Substrates on which Mapecoat TNS Fast 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 surface when in use, 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. Mapecoat TNS Fast must only be applied on substrates with a level surface. All sharp corners, the edges of steps and fillets must be rounded off (for example, in the case of stadium stairs). Taking such precautions during the preparation phase allows the consumption rate per square metre to be kept under control and also prevents unsightly defects forming on the surface. Finally, to complete the substrate preparation, only in the case of concrete structures, the surface must be treated with suitable power tools (e.g. shot-blasting or grinding with a diamond disk) to remove all traces of dirt, cement laitance and crumbling or detached portions and to make the surface slightly rough and absorbent.

In the case of cement conglomerate substrates, in order to grant the correct adhesion of Mapecoat TNS Fast, a suitable primer must be applied on the dry substrate. 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 Mapei Triblock P three component epoxy cementitious primer. Apply the first coat of Mapecoat TNS Fast 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. Any cracks in the substrate must be repaired before the applications using Eporip epoxy resin. If necessary, the repair concrete portions should be carried out with cement mortars from the Mapegrout or Planitop ranges. Select the most suitable product according to the reparation needs and the loads to which the flooring will be subject. Mapecoat TNS Fast must be applied on a levelled substrate, so that it can be applied evenly and uniformly.

In the case of substrates made of 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. Cracks must be filled and repaired using reactive products such as Mapei Ultrabond Turf 2 Stars Pro, Ultrabond Turf 2 Stars or Ultrabond Turf PU 2K. For hollows up to 2 cm deep, we suggest a balanced mix of the products mentioned above (Ultrabond Turf) and 15-20% by weight of Mapei Quartz 0.9 silica sand.

In the case of particularly deteriorated or dirty areas of asphalt, it could be necessary to remove these areas and then repair them with Mape-Asphalt Repair 0/8 cold-applied reactive asphalt. Mapecoat TNS Fast can also be applied to freshly laid bituminous conglomerate substrates, allowing the heat from the asphalt to dry the product even faster. This is particularly effective when applied in cold weather. It is recommended that Mapecoat TNS Fast is applied to bituminous conglomerate substrates with a maximum bitumen content of 6%. For higher bitumen contents, contact the Sports System Technology Service or MAPEI Technical Service to verify and possibly to advise on the correct application of Mapecoat TNS Fast, depending on the local conditions of the substrate. Mapecoat TNS Fast can also be applied on old asphalt surfaces: in such cases, make sure the surface is prepared in a suitable way (by water jet or grinding). Evaluate beforehand if Mapecoat TNS Primer EPW should be applied.

Preparation of the product
Dilute Mapecoat TNS Fast with max. 10% of water. Dilution rate will vary depending on surrounding temperature and substrate temperature. 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 Fast can be applied with 5-10 mm mohair-type roller, using conventional techniques. For large surface areas, the coloured coating can be applied more quickly using a HVLP (High Volume Low Pressure) air mix spray system or a membrane pump. This system generally requires the application of 2 coats of Mapecoat TNS Fast, with a waiting time of 8–12 hours between each coat under normal humidity and temperature conditions. As soon as the surfaces have been coated, they should be protected from rain to prevent Mapecoat TNS Fast coming into contact with water during its initial drying phase, otherwise its adhesion and the overall quality of the work could be affected.
