Mapefloor PU 400 LV

WHERE TO USE

Thanks to its special formulation Mapefloor PU 400 LV is used for internal and external car-parks and concrete substrates with cracks or risk of cracking that require a coating with a high degree of elasticity. Mapefloor PU400 LV is used in the Mapefloor Parking System HE cycle to form an elastic protective and waterproof coating on road surfaces in multi-storey car-parks and on roofs and surfaces with vehicle access, including external surfaces. Mapefloor PU 400 LV is also used in the Mapefloor Parking System ME cycle to form an elastic protective and waterproof coating on road surfaces for the intermediate levels in multi-deck carparks.

TECHNICAL CHARACTERISTICS

Mapefloor PU 400 LV is a two-component, coloured, fillerized polyhuretane resin-based formulate, according to a formula developed in the MAPEI research laboratories. Mapefloor PU 400 LV has excellent crack-bridging capacity for cracks that have already appeared or that could potentially form in substrates, even at temperatures down to -20°C. Refer to the Mapefloor Parking System HE and Mapefloor Parking System ME Technical Data Sheets for their respective crack-bridging classes. Mapefloor PU 400 LV also has good resistance to mechanical stresses and loads.

RECOMMENDATIONS

· Do not apply Mapefloor PU 400 LV on substrates not adequately prepared and primed as specified.

· Do not apply Mapefloor PU 400 LV on substrates with more than 4% moisture content or on substrates with capillary rising damp (consult Mapei Technical Services).

· Do not dilute Mapefloor PU 400 LV with solvent or water.

· Do not apply Mapefloor PU 400 LV on dusty or crumbling substrates.

· Do not apply Mapefloor PU 400 LV on substrates with oil or grease stains or with stains in general.

· Do not mix partial quantities of the components to avoid mixing errors; the product may not harden correctly.

· Protect the product from water for at least 24 hours after application.

· The temperature of the substrate must be at least 3°C above dew point to reduce the risk of condensation.

· Do not expose the mixed product to sources of heat.

· If areas where the product is being applied need to be warmed up, use electric heaters only (heaters that run on fossil fuels give off carbon dioxide and water vapour that could affect the finish of the coating).
