Tanking
Tanking
Strict temperature control should be maintained throughout the process. Generally the temperature of Mastic Asphalt should not exceed 230 degrees centigrade.
Mastic Asphalt Tanking should be laid in three coats. Each coat of each bay should be spread evenly and uniformly by means of a float, to the recommended thickness, on to the previously prepared surface, the separating membrane or the preceding coat. Timber or metal gauges should be used in order to ensure accuracy.
Each coat of Mastic Asphalt should be followed by the succeeding coat as soon as is practicable without delay, since exposure to contamination, for example, by dust or dirt, might impair adhesion.
