Description
BAC 50 Biocide 5L | 50% Concentrated Moss & Algae Remover
Eliminate moss, algae, mould, and lichen with our professional-grade BAC 50 Biocide. Formulated with a highly concentrated 50% Benzalkonium Chloride base, this industrial-strength formula deep-cleans and protects exterior hard surfaces.
Unlike standard retail washes, BAC 50 bonds to the surface to provide a preventative barrier that keeps organic growth away for up to 1–2 years.
Why Choose BAC 50?
- Trade Strength: 50% active concentration built for professional contractors and heavy-duty commercial use.
- Versatile Use: Perfect for roofs, patios, block paving, driveways, rendered walls, and fencing.
- Weather-Driven Action: A slow-acting formula that kills organic cells on contact, allowing wind and rain to naturally wash away dead debris over time.
- Eco-Friendly: Fully biodegradable when diluted, requiring fewer applications over time.
Quick Dilution Guide
- Roofs & Render: Dilute 1:20 with clean water.
- Patios & Paving: Dilute 1:30 with clean water.
- Heavy Industrial Cleaning: Dilute as required based on contamination.
How to Apply (No Rinsing Required)
- Prep: Ensure the surface is completely dry. Avoid applying if rain is expected within 24 hours.
- Apply: Mix your required ratio and apply evenly using a low-pressure sprayer or a soft brush. (For best results, apply in cool, cloudy conditions).
- Leave It: Do not rinse it off. Allow the product to dry naturally. A dry period of at least 24 hours is required for optimal effectiveness.
What to Expect (Working Time)
- First Few Days: Initial discolouration as the biocide rapidly kills algae and moss on contact.
- 6 to 12 Months: Complete, deep cleaning of heavily infested surfaces as natural weathering washes the dead contaminants away.
- Next 1 to 2 Years: Active, long-term protection against regrowth.
Important Precautions
- Safety First: For professional use. Always wear appropriate PPE (gloves and goggles) during handling.
- Pets & Children: Keep pets and children away from treated areas during application and until the surface is completely dry.
- Storage: Store in a cool, dry place in the original tightly sealed container. Protect from frost and direct sunlight.
