Description
TC Brush Applied MASTIC is a thixotropic brush applied coal tar coating for ambient temperature, below grade application. A time proven coating method for applying corrosion protection to metal fittings, flanges, valves, tanks, mechanical couplings, anode connections and other difficult and irregular configurations, excellent for small hole technology.
It is also designed to protect concrete surfaces from adverse environments. TC Brush Applied MASTIC is easy to apply by brush or rubber glove. As a liquid it is highly conformable and resists drips and sags.
The more it is brushed the more flowable it becomes.
Application
Recommended Application Apply two coats of mastic at12 mils each. The mastic should be brushed or worked with a rubber glove to allow the solvents to release. Work in a well ventilated area. Recommended eight hours as a minimum time until backfill.
Option: TC Reinforcing Scrim, a polyethylene wrap, can be applied over the mastic or between mastic layers, giving the coating added strength and impact resistance and acting as a secondary barrier if the mastic has not completely hardened prior to backfill.
Surface Preparation
Prior to coating application the surface should be clean, dry, free of oil, grease, rust, scale and loose coating.
Composition
LOW VOC, Rating 327g/l, Solids 51.47% Meets or exceeds the VOC regulations for all states excluding California and parts of Arizona.
RESISTANT TO A WIDE VARIEITY OF CHEMICALS TC Mastic is ideal protecting many areas that are exposed to chemical spills, fumes and splash zones. (Consult the Chemical Resistance Chart)
