– mop application: the temperature at which the asphalt’s apparent viscosity is 125.

The application of hot bitumen, with a roofer's hand mop or mechanical applicator, to the substrate or to the felts of a bituminous membrane.

The application of hot bitumen with a mop or mechanical applicator to the substrate or plies of a bituminous membrane.

Note: If there are simultaneous mop and mechanical spreader applications, in order to avoid the use of two kettles, the EVT for mechanical spreader application may be used for both application techniques.

Note: If there are simultaneous mop and mechanical spreader applications, in order to avoid the use of two kettles, the EVE for mechanical spreader application may be used for both application techniques.

When asphalt is used to secure insulation, it should be applied at temperatures 15°C to 20°C below the recommended EVT for interply hand mopping of that particular asphalt.
