Fiber Base Coat Stucco Sanded

SPEC MIX® Fiber Base Coat (FBC) is a dry, preblended cement based stucco engineered with proprietary admixtures and fibers that are computer batched for consistency and performance unmatched by traditional field mixed stucco. SPEC MIX FBC has a custom blended sand gradation that increases the wall flexural strength while reducing cracking and crazing. The custom sand gradation also provides excellent workability and finishing properties for the applicator over a traditional field-mixed source.

Designed for both One Coat and traditional Scratch & Brown Coat systems, SPEC MIX FBC reduces shrinkage and increases long term durability and bond strength of the application. When gun or hand applied by a qualified applicator, SPEC MIX FBC is approved by the International Code Council (ICC) as a one-hour fire rated wall when applied as a One Coat application, ESR 3018. Each SPEC MIX manufacturer certifies that SPEC MIX stucco products are designed to meet the project specifications and applicable ASTM standards.
