Brand: Stucco Supply Co of San Jose, Inc.

This is a listed siding assembly. Listing 8140-2395:0001. This site cites sfm-12-7a-1. Match the model and orientation. A listing is not a permit.

Superior Stucco Uniwall is a fiber-reinforced, one-coat cementitious wall-covering system. Current CAL FIRE OSFM listing 8140-2395:0001 covers a specified exterior assembly with a weather-resistive barrier, metal lath, 3/8-inch Uniwall base coat, and 1/8-inch finish coat. ICC-ES ESR-5231 evaluates Uniwall as an alternative exterior wall covering over multiple listed substrates and framing types, subject to the report's conditions.

Models named on the listing

Model	Application
Uniwall Concentrate	field-mixed one-coat base coat in the listed Uniwall exterior wall system
Uniwall Sanded Exterior	factory-sanded variant covered by ICC-ES ESR-5231; verify against the OSFM assembly

The OSFM listing applies to the complete named assembly, not Uniwall concentrate by itself. Match the weather-resistive barrier, lath, base and finish coats, substrates, fasteners, thicknesses, mixing, curing, and installer conditions to the current listing and ESR-5231.
ESR-5231 evaluates structural, durability, weather-protection, construction-type, and specified fire-resistance uses. It does not replace the separate OSFM WUI listing or expand that listing.
OSFM listing is not a permit. The authority having jurisdiction decides.

Where this applies

A product is a national record; where it applies is a fact about a place. The rule that binds a given address — and every product matching it — is published on that place's own answer page, linked above and re-linked by the location lens. The complete per-place claim graph for this record, including every open official check, is in its JSON twin.
