The new Mapefloor parking deck system from Mapei is a two-component, flexible polyurethane system is designed to provide an elastomeric waterproofing membrane for heavy pedestrian and vehicular traffic. It may be used in multi-story parking garages and areas with heavy vehicular traffic, as well as on suspended pedestrian walkways and balconies.
The Mapefloor parking deck system is available in two formats. The standard system is a minimum 40-dry-mil (1-mm) system, excluding aggregate and primer. The heavy-duty system, which is ideal for high-wear areas such as spiraled ramps, turn and drive lanes, and ticket booths, is a minimum 55-dry-mil (1.4-mm) system, also excluding aggregate and primer.
There are four components in each of the systems:
• Mapefloor Primer (the standard system) and Mapefloor Primer Fast (the heavy-duty system), two-component epoxy primers, are used for priming and consolidating the worn concrete surface. Mapefloor PU 400, a two-component polyurethane basecoat, is applied over the primer and acts as a waterproofing membrane.
• Mapefloor Finish 415 NA, a two-component, aromatic polyurethane topcoat, is used in areas of parking garages not exposed to the sun.
• Mapefloor Finish 450, a two-component, aliphatic polyurethane topcoat, provides UV protection in areas of garages that are constantly exposed to the sun.
