Mapei Mapecoat TNS Extreme

Mapei Mapecoat TNS Extreme is a two-component water-based rapid-drying epoxy-acrylic resin with selected fillers used to form a durable floor coating suitable for car traffic and pedestrian areas as well as cycle lanes.

Best Uses

Mapecoat TNS Extreme is a two-component, water-based, rapid-drying, epoxy-acrylic resin which, thanks to its excellent physical and mechanical properties, may be used to colour and protect high-traffic surfaces used by vehicles, pedestrian areas and cycle lanes. The special formulation of Mapecoat TNS Extreme allows for its application on bituminous and cementitious conglomerate substrates and pavers. Thanks to the selected fillers used in its special formulation, Mapecoat TNS Extreme may be used as a coating on external flooring that needs to have a high level of slip-resistance, including in wet conditions, such as access driveways, line marking in general, cycle lanes, etc.

Mapecoat TNS Extreme is easy to apply and is rapid-drying and treated surfaces can be put back into service quickly. This means Mapecoat TNS Extreme may be applied directly on hot bituminous conglomerate, particularly suitable in the case of applications using the stamped asphalt technique. Unlike conventional colouring systems, Mapecoat TNS Extreme allows highly durable, non-slip surfaces to be created that maintain their surface finish over the years, including in wet conditions.

The mechanical properties of the coating, combined with its high resistance to chemical products potentially harmful to surfaces (such as de-icing salts, oil and fuel, etc.), also make Mapecoat TNS Extreme suitable for coating large areas, either those that need to be treated periodically to prevent ice forming or for routine cleaning purposes. Mapecoat TNS Extreme 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, along with the other shades offered thanks to the ColorMap automatic colouring system, also allow for the creation of personalised colours. Mapecoat TNS Extreme is tested by Weather-Ometer to simulate severe physical and environmental cycles and is able to resist prolonged exposure to sunlight, particularly ultraviolet rays.

Mapei Mapecoat TNS Extreme is ideal for:

• Protecting and colouring car traffic areas, such as pedestrian crossings, parking areas, access ramps
• Coating and colouring of outdoor areas subject to a high level of footfall, including in wet conditions
• Coating and protecting bituminous conglomerate surfaces with an imprinted asphalt finish
• Colouring and protecting cycle lanes, urban design, multipurpose and sport areas
• Colouring pavements and pedestrian areas

Application

Preparation of the substrate
Substrates on which Mapecoat TNS Extreme is to be applied must be compact, solid, and flat and have no detached or loose areas. Specifically, the surface on which the coating is to be applied must be strong enough to withstand the loads acting on the substrate when in use, especially in car traffic areas. In the case of concrete substrates, to allow the correct adhesion of Mapecoat TNS Extreme, it is necessary to apply a suitable primer on the dry surface. For surfaces with residual humidity up to 3%, use Mapei Mapecoat TNS Primer EPW. In the presence of residual humidity between 3-6%, apply a suitable chemical barrier made of the three-component epoxy-cementitious primer Mapei Triblock P. Apply the first coat of Mapecoat TNS Extreme within 24 hours of applying Mapecoat TNS Primer EPW and within 36 hours if a Triblock P chemical barrier has been applied. Any cracking present in the concrete substrate must be repaired by applying Mapei Eporip or Mapei Eporip SCR injectable epoxy resin.

Repair, skim, or smooth over areas of damaged or deteriorated concrete with a cementitious mortar from the Mapegrout or Planitop ranges, according to the type of damage to be repaired and the loads the flooring needs to withstand. The substrate on which Mapecoat TNS Extreme is to be applied must be levelled off so that it may be applied evenly and uniformly. In the case of bituminous substrate, cracks must be filled and repaired using reactive products such as Mapei Ultrabond Turf 2 Stars Pro, Mapei Ultrabond Turf 2 Stars or Mapei 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% in weight of Mapei Quartz 0.9 silica sand. Remove badly damaged and worn bituminous conglomerate and replace it with a new layer, with a ready-to-use, reactive product, such as Mapei Mape-Asphalt Repair 0/8. Then, before applying Mapecoat TNS Extreme, any traces of dust or dirt on the surface must be vacuumed off or removed.

Mapecoat TNS Extreme may also be applied on bituminous conglomerate substrates as soon as they have been applied so that the heat from the asphalt dries the product even more quickly, particularly when applied in cold weather. It is recommended to apply Mapecoat TNS Extreme on bituminous conglomerate substrates with a maximum bitumen content of 6%; for higher levels, contact the technical support team at Sports System Technology or the MAPEI Technical Services Division to verify and agree on the correct application of Mapecoat TNS Extreme, according to the condition of the substrate. Mapecoat TNS Extreme may also be applied on old asphalt substrates: in such cases, make sure the surface is prepared properly by hydro-blasting it with water or by grinding, then check to make sure it is feasible to apply Mapecoat TNS Primer EPW.

Preparation of the product
Mapecoat TNS Extreme is a two-component product. The two components must be mixed together just before application. Mix component B thoroughly and add the contents of component A. Mix again for at least 2 minutes with an electric mixer fitted with a mixing attachment at low speed to avoid entraining air into the product until they are completely blended. Once the two components of Mapecoat TNS Extreme have been mixed together, dilute with 5-15% of water and mix again using the same procedure as before.

Application of the product
Apply Mapecoat TNS Extreme by spraying with an air-HVLP spray gun, membrane pump, roller, spreader, or rubber squeegee. Particularly in the case of coatings on car traffic areas, it is recommended to apply the product with a trowel or by spray, which will also increase the durability of the surface. To even out the surface of a particularly porous bituminous conglomerate or for localised repairs (such as cold joints), add up to 25% by weight of Mapei Quartz 0.5 to Mapecoat TNS Extreme and apply it with a trowel in order to regulate and even out the consumption of successive layers. Mapecoat TNS Extreme must not be used to fill particularly thick areas or gaps.

The application cycle generally consists of at least 2 coats of Mapecoat TNS Extreme; wait 2 hours between each coat in normal conditions (50% humidity and an environment temperature of +23°C). Lower temperatures may increase the drying time. As soon as the surfaces have been coated, they should be protected from rain to prevent
Mapecoat TNS Extreme from coming into contact with water during its initial drying phase, otherwise, its adhesion and the overall quality of the work may be affected.
