MMC-Pro – Moss Killer

MMC-Pro is a concentrate moss killer for hard surfaces such as drives, roofs, paths and block paving. It also treats mould and algae, and needs no pressure washing or scrubbing: dilute it, apply it with a sprayer, and leave it to work.

MMC-Pro is a combination anti-viral/anti-bacterial disinfectant, fungicide/algaecide and detergent. It kills mould, algae and moss in typically 2-4 days, then continues cleaning slowly over the following weeks and months.

MMC-Pro is suitable for all exterior hard surfaces, including drives, roofs, paths, tennis courts, artificial turf, concrete, tarmac and block paving.

Depending on the surface, the dilution rate used and natural weathering, MMC-Pro will generally prevent regrowth for approximately 9 months, and longer on absorbent surfaces such as timber fencing.

MMC-Pro is readily biodegradable and pH-neutral. It contains no bleach or acids and is fully HSE-approved.

Target organisms

• Green mould and algae: killed in 2-4 days when applied according to the instructions.
• Black mould: killed in typically 10-14 days, though pigment staining, if present, is likely to persist.
• Lichen: killed gradually, over a period of several months; natural weathering then takes a few more months to remove the dead growth.

Cleaning

MMC-Pro is not a general-purpose or instant “cleaner”. In most cases, though not all, product residues lift ingrained dirt slowly over a few months from application, leaving a cleaner, brighter surface. Rainfall and other variables mean this cleaning action varies from site to site.

Prevention

Product residues typically prevent algal regrowth for 8-9 months on south-facing, exposed surfaces, but for less time where surfaces are permanently shaded or damp. MMC-Pro is also suitable as a pre-paint treatment.

Coverage rate

Applied with a knapsack sprayer, the standard coverage rate is 4-5 m² per litre of dilute.

Operating conditions

Apply to dry surfaces and leave for 3-5 hours so the chemical can work effectively.

Key precautions

Approved under the control of pesticides regulation 1986 for use as directed. HSE 7824. Use MMC-Pro safely. Always read the label and product information before use.

Contact with plant life should be minimised. Limited run-off or over-spray onto grass, soil or hardy plants will not normally cause damage. Where heavier run-off or over-spray has occurred, the area should simply be flooded with fresh water.

Pets and unprotected persons should be kept off the treated surfaces until the product has first dried, typically 3-5 hours.
