Application Guidance
Before application, substrates should be assessed for persistent damp conditions. Moisture sources such as rising damp, plumbing faults or poor drainage should be addressed to prevent recurrence. Remove all loose material with a soft brush, and power washing is recommended for better surface preparation.
Apply SPSEnvirowall Fungicidal Wash liberally using a pressurised sprayer, roller, or brush, ensuring thorough saturation. A minimum contact time of 48 hours is required to allow the biocide to act fully. Once dried and effective, dead growth should be removed mechanically with a steel brush or pressure washer.
Environmental & Weather Considerations
Application and curing should occur under stable conditions:
-
Temperature range: +5°C to +25°C
-
Relative humidity: Less than 95%
-
Substrate pH must be below 8
-
Avoid direct sunlight, rain, wind, frost, or high substrate temperatures (>30°C)
Surfaces should be protected for at least 24 hours post-application from adverse weather using scaffold sheeting or similar. Failure to comply may result in wash-off, film damage or discolouration.
Shelf Life & Storage
The product remains effective for up to 12 months when stored in original, unopened containers in dry conditions above +5°C.
Cleaning & Waste
Tools must be cleaned immediately with water after application. Waste materials should not enter drainage systems.
Compliance and Handling
SPSEnvirowall Fungicidal Wash is formulated with 2-Octyl-2H-isothiazol-3-one, a biocide that may produce allergic reactions. It carries hazard statements relating to skin and eye irritation and environmental toxicity. Use appropriate PPE and refer to the Material Safety section below for full handling guidelines.
