Fiber Base Coat Stucco and Scratch and Brown


Product Overview

SPEC MIX® Fiber Base Coat Stucco, Scratch and Brown and Colored Finish Coat Stucco are preblended and formulated to ASTM C926 and IBC standards for maximum workability and reduced shrinkage. SPEC MIX®, an innovator in preblended stucco development, designs products with a goal of quality, consistency and efficiency. High quality raw materials, preblended with sand to provide outstanding workability and excellent finishing properties, can be used with the innovative SPEC MIX silo delivery system to increase job site material quality and productivity.

Product Description, Applications

SPEC MIX products are a blend of quality aggregates, cementitious materials, stable pigments and fibers that meet all applicable ASTM and UBC standards. Packaged dry, with sand already added for increased consistency, SPEC MIX Fiber Base Coat (FBC), Scratch and Brown and Colored Finish Coat Stucco offer performance unmatched by traditional field-mixed stucco.

SPEC MIX Fiber Base Coat is a code-approved, high performance, fiber-reinforced, premixed stucco basecoat for commercial and residential applications. Designed to minimize crazing and cracking, it can be applied, by trowel or gun, to 3/8"–1/2" (9.5–12.7 mm) and 3/4"–7/8" (19–22.2 mm) thick stucco, One-Coat and traditional Scratch and Brown applications. Used in accordance with its code report, SPEC MIX Fiber Base Coat can be installed for 1-hour fire-resistive wall assemblies and for non-combustible construction. It is suited for single-family homes, multi-family complexes and commercial applications.

SPEC MIX Scratch and Brown is a dry, premixed stucco base coat for commercial and residential applications. It can be used as the scratch or brown coat in a 3-coat application and is formulated to be applied by trowel or gun. SPEC MIX Scratch and Brown produces a non-load-bearing, aesthetically pleasing exterior veneer or interior finish on metal buildings and concrete, masonry or stud walls.

SPEC MIX offers a patented gravity-fed silo dispensing system to increase job site consistency, quality and productivity. With this system, the preblended mortar mix, grout and reusable bulk bags, palletized and protected against moisture, are delivered to a job site. Before the project starts, SPEC MIX representatives deliver the silo dispensing system. Mixing is easy and takes only 5 minutes. When the job is complete, SPEC MIX representatives pick up the silo, as well as the reusable bulk bags.
