About this product
Viking TB Mastic is a cold applied, trowel-grade coal tar based polymer modified roofing mastic. Unlike other coal tar based mastics, Viking TB Mastic is a non-sag coal tar mastic designed for the installation of flashing systems on both vertical and horizontal surfaces. Viking TB Mastic can also be used for the installation of pitch pockets, roof drains, vent pipes or wherever a mastic product is required. Advantages: Non-Sag: Viking TB Mastic is specially formulated to not run or sag at normal roof temperatures. Unlike most coal tar mastics, Viking TB Mastic will hold on vertical surfaces. Ease of Application: The unique formulation provides a smooth workable consistency which reduces application time and cost. Multi-purpose: Viking TB Mastic is specially designed for use with a coal tar roof system. It can also be used to make repairs on coal tar based built-up roof systems. Coal Tar Based: Coal tar provides a natural resistance to moisture, chemicals, ultraviolet radiation and aging. Viking TB Mastic polymer modified formulation combines the inherent water resistance of coal tar with the flexibility of advanced polymer for unmatched durability. Factory Formulation Ensures Uniform Quality: Viking TB Mastic is factory formulated under rigid quality control conditions to insure uniform product quality. This eliminates the variables inherent to the job site preparation of roof materials where quality control depends entirely on the individual roofer's expertise.
