Foster® 32-80™ BRIDGING MASTIC ENCAPSULANT-LOCKDOWN
FOSTER ® BRIDGING MASTIC ENCAPSULANT-LOCKDOWN
Foster ® Bridging Mastic is a quality, dual-purpose coating designed specifically for the asbestos abatement industry.
Bridging Mastic is a field proven bridging encapsulant. Upon cure, 32-80 forms a tough, light colored, washable, abrasion resistant, elastomeric coating that economically abates the release of asbestos fibers from both conventional and spray applied asbestos-containing materials (ACM). Used with glass cloth, 32-80 is ideal for use over interior pipe covering and boiler lagging insulations.
Bridging Mastic can be diluted a maximum of 1:1 (water to 32-80) to produce an extremely effective lockdown (post-removal residual encapsulant). Applied at 400 sq. ft./gal., 32-80 cures to form a visible film effectively abating the release of remaining fibers.
BRIDGING MASTIC meets the requirements of NFPA 90A and 90B. Meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 41 g/l, less water and exempt solvents.
Protect from freezing until dry. Not recommended for exterior use; select CP-211 instead. Do not store or apply below 40°F (4°C) or above 100°F (38°C). As a lockdown, do not apply to surfaces in excess of 170°F (93.3°C). Not suggested for use on floors. 04-08

AVERAGE WEIGHT/U.S. GALLON (ASTM D 1475):
10.5 lbs. (1.26 kg/l)
AVERAGE NON-VOLATILE (ASTM D 1644):
41.5% by volume
COVERAGE RANGE (FSTM 71):
(Subject to the type of surface being coated.) Wet coverages shown below are for smooth non-porous surfaces. Porous or rough textured surfaces will require higher gallonage to obtain required dry thickness.

As A Lockdown
400 sq. ft./gal. (9.8 m2 /liter)
Mild when wet;
none when dry.
SERVICE TEMPERATURE LIMITS (FSTM 70):
