FORTIS, 10 L, mold remover. External works

The professional-volume FORTIS — built for contractors and property teams clearing mold and weathering from large facades, long fence lines, cemetery monuments or a whole street of paving in one run. Probiotic formula lifts plant growth and atmospheric staining without damaging brick, render, stone or concrete, and won’t harm surrounding vegetation.

Why crews choose FORTIS:

• Vegetative-bacteria formula with a synthetic-acid boost that penetrates the surface, not just the stain.
• Safe for the treated surface and everything growing next to it.
• Hypoallergenic, chlorine-free — no need to clear the site of people or pets during the job.
• Certified to US standards: USDA, NSF, SaferChoice, Green Circle.

Application: Clear loose dirt from the surface first. Apply FORTIS and leave for 10 minutes, then brush or sponge and rinse with water. For thick, established buildup, leave for up to 8 hours or overnight. To stop mold returning, let the product work into the surface rather than rinsing it off immediately.

Coverage: roughly 1 litre per 4–8 m² depending on the severity of staining — a 10 L container is sized for a full job across multiple surfaces.
