ActiWash Biocide is a broad-spectrum antibacterial disinfectant, algaecide and cationic detergent for the control of mould and algae on all hard surfaces.
ActiWash Biocide typically controls targeted growth in 2-4 days, without the need for pressure washing or scrubbing and also has a slow cleaning action in the following weeks and months.
Active Ingredients: 9.90% w/w (99 g/l) didecyl dimethyl ammonium chloride
The active substance in Actiwash Biocide, helps to remove algae mould and other single celled organisms from hard surfaces, by disruption of the cell membrane. Preventing photosynthesis and other physiological processes, leading to visible results in 12-24 hours.
Once dry Actiwash Biocide adsorbs onto hard surfaces creating a molecular film, which provides preventative action for a number of months. Contains no bleach or chlorine, and is not corrosive, almost completely pH neutral.
Green algae typically disappear within a week, red algae in 2-3 weeks. Well-established dark stains may take several months, but you will see a gradual lightening over time and should consider light brush agitation for heavily contaminated areas.
Where to Use:
Actiwash Biocide is suitable for use on all exterior hard surfaces including drives, roofs, paths, tennis courts, artificial turf, concrete, tarmac & block paving. Preventative action is significantly reduced when applied to loose or friable surfaces such as gravel.
When to Use:
- Apply at any time of year when algae is present on both porous and non-porous hard surfaces.
- Apply onto dry surfaces and allow for 5-6 hours prior to rainfall, so the chemical can adsorb effectively.
How to Use:
- Brush off any heavy growth of surface detritus such as leaves which may prevent Actiwash contacting the surface affectively and evenly.
- Apply to dry surfaces only.
- Apply via low pressure hand held or knapsack sprayer
- Add half of the required water to the spray tank.
- Measure out and add the required amount of product to the spray tank.
- Add the remaining amount of water to the spray tank.
- Saturate the surface and leave to dry.
- Avoid contact with non-target organisms or plants.
