Overview
ET Industrial Eco Roof Guard (ERG) is a powerful, non-caustic and biodegradable solution for removing mould, mildew, and lichen from outdoor surfaces. This ready-to-dilute concentrate is simple to use with no scrubbing or pressure washing required. ERG penetrates growth over time and creates a protective barrier that helps prevent regrowth.
