The company’s FIBER BASE COAT is dry, premixed cement-based stucco engineered using a proprietary formula that’s computer batched for consistency and performance superior to field mixed stucco. SPEC MIX FBC stucco is a code-approved product that starts with a specially blended ASTM C897 sand gradation that increases the wall’s flexural strength while reducing cracking and crazing.

Designed for both one-coat and traditional scratch and brown wall systems, SPEC MIX FBC is proven to reduce product shrinkage that increases long-term durability. Whether gun or hand-applied, SPEC MIX FBC is approved by the ICC as a one-hour fire rated wall in one-coat applications.
