A broad spectrum anti-bacterial disinfectant fungicide, algaecide and detergent, MMC-PRO doesn’t contain bleach or acids and is biodegradable. It is 100 per cent non-abrasive and should be applied in dry conditions at dilutions of 1:4 to 1:9 with water. There is no need to scrub or pressure wash.
Treatment is typically effective in two to four days and the secondary detergent action will help to gently clean the treated surface in the following weeks and months.
Any dead growth not removed by the elements can be lightly brushed away. The price from ALS is £21.20 for five litres.
