Moss and similar heavy growth and vegetable matter should be cleared from the surface using a stiff bristle brush or wire brush if necessary. Pressure washing may also help. Ensure the surface is as clean as possible, sound, free of loose or flaking material and dry or damp (but free of standing water) before applying Destroy IT.

Shake well before use.
Apply the solution by brush or broom to the affected area.
After 24 hours, remove any stubborn residues of organic growth by brush or scraper and re-coat any persistent stains.
After application, Destroy IT should be left for 24 hours before any further preparation or painting to avoid spreading active spores to the surrounding area.
