Fungicidal Wash 5ltr

SPSEnvirowall Fungicidal Wash is a specialist masonry biocide designed to sterilise and cleanse exterior surfaces affected by organic growths such as algae, moss, mould, and fungi. This water-based treatment incorporates a carefully balanced blend of biocides that are effective against a wide range of microbial organisms, making it a critical preparatory product in external wall insulation and general façade maintenance.

Product Features & Benefits

• Highly Effective Formulation: The active biocides in SPSEnvirowall Fungicidal Wash work to kill both visible and unseen organic contaminants, including spores, ensuring long-term protection.

• Versatile Application: Suitable for a range of common substrates including concrete, brick, stone, and render.

• Easy to Apply: Can be brushed, rolled, or sprayed on, providing flexibility for site conditions and access challenges.

• Deep Penetration: Designed to soak into the substrate’s capillaries, enhancing efficacy and longevity of results.

• Preparation Enhancer: Provides an essential preparatory step before applying coatings or insulation systems, helping to improve surface condition and adhesion.

• Environmental Considerations: Toxic to aquatic life with long-lasting effects – hence, precautionary environmental care is recommended during application.

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.
