Although focused on coloured render, the principles and techniques outlined in the manual also apply to other exterior surfaces affected by algae and microbial growth, including:
Paths and patios
Driveways
Play areas and hardstanding
Tennis courts
Roofs and other exterior finishes
Soft washing requires proper planning and safe working practices. The manual includes clear guidance on:
PPE requirements
COSHH awareness
Safe handling and application of biocides
Environmental protection and run-off control
Risk assessments and RAMS
This ensures contractors can work responsibly while meeting client and regulatory expectations.
The manual also includes essential technical product information to support correct chemical selection, dilution and application across different surface types and site conditions.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
