SPEC MIX Scratch and Brown Fiber Reinforced Stucco is produced under strict manufacturing standards, and complete quality control measures are implemented with each batch. A digital printout displaying the proper proportions per batch may be kept as a permanent record. Each SPEC MIX® manufacturer certifies that SPEC MIX® stucco products are designed to meet the project specifications and applicable ASTM standards.

SPEC MIX Scratch & Brown Fiber Reinforced Stucco is a custom blend of cementitious materials, additives, aggregates and alkali resistant fibers meeting ASTM C 926 requirements. The special sand gradation used provides excellent workability and finishing properties for the applicator as well as increases the flexural strength of the wall while reducing cracking and crazing common with traditional field-mixed stucco.

SPEC MIX Scratch & Brown Stucco Fiber Reinforced Stucco can be installed over framed wall construction that includes a solid backing such as Fiberboard, Gypsum Sheathing and Wood Based Sheathing. The product’s adhesion properties and versatility make it the perfect basecoat when applied over Concrete and Masonry substrates.
