Rust-oleum 27400CAL Mold Control Spray 14 Oz

Product Description

The RUST-OLEUM 27400CAL is a 14-ounce aerosol mold control spray formulated to kill, clean, and prevent mold and mildew growth on contact. Part of the Concrobium line, this 3-in-1 product eliminates existing mold spores, removes staining, and leaves a protective barrier that resists future growth. The aerosol valve is designed to spray in any direction, including upside down, allowing technicians and service pros to reach tight spaces, cracks, and crevices that standard trigger sprayers cannot access. The formula contains no chlorine bleach and no volatile organic compounds (VOCs), making it suitable for use in enclosed or occupied spaces where chemical exposure is a concern.

This product is used in residential and light commercial settings where mold remediation or prevention is required. Typical applications include HVAC air handlers, ductwork interiors, crawl spaces, basements, bathroom surfaces, and any area prone to moisture accumulation. It is well suited for HVAC technicians, plumbers, restoration contractors, and property maintenance professionals who encounter mold during routine service calls or remediation work.
