SPEC MIX Fiber Base Coat is engineered for both One Coat and conventional Scratch & Brown Coat systems. This product is a dry, pre-blended cement based stucco designed with proprietary admixtures and fibers that are digitally measured for consistency and performance unrivaled by traditional on-site mixed stucco. SPEC MIX is reducing cracking and crazing by using a custom blended sand gradation, which provides outstanding workability and finishing properties for the stucco applicator over a traditional field-mixed batch.
