PRODUCT DESCRIPTION

Key Features:

  • Concentrated formula: 1 container makes 25 litres of ready-to-use solution
  • Treats up to 125m² from a single 5L container
  • Broad-spectrum biocide targeting multiple organic contaminants
  • Suitable for use as a standalone treatment or pre-treatment before sealing/painting
  • Easy application with a brush or garden sprayer

What It Treats

Surface Types:

  • Concrete and brickwork
  • Paving stones and blocks
  • Tarmac driveways and paths
  • Natural stone (sandstone, limestone, slate, granite)
  • Cement mortar joints
  • External walls and facades

Organic Contaminants:

  • Green algae and lichens
  • Green and black mould
  • Moss growth
  • Organic stains on masonry
  • Microscopic spores and root systems

Why Surface Treatment Matters

Organic growth isn't just unsightly; it actively damages your property. Moss and algae cause deterioration through:

Chloride Erosion: Moss roots retain moisture up to 16 times their dry weight, preventing mortar joints from drying and encouraging the formation of corrosive salts that accelerate mortar breakdown.

Freeze-Thaw Damage: In winter, moisture-laden organic growth freezes and expands, rupturing mortar surfaces and allowing deeper water penetration that leads to complete joint failure.

Regular treatment with Bio-Wash prevents the accumulation of organic matter that can damage buildings and hard landscaping over time.

How to Use

Surface Preparation

  • Ensure surfaces are relatively dry with no standing water
  • For areas with weeds, treat with appropriate weed killer first
  • No other preparation required

Application Methods

Method 1: Post-Pressure Washing Surface Sanitiser

  1. Dilute 1 part Bio-Wash with four parts clean water
  2. Apply liberally using a brush or a low-pressure garden sprayer
  3. Do not rinse off
  4. Leave to dry for a minimum 1-2 hours before applying subsequent coatings
  5. Perfect for sanitising surfaces before sealing, painting, or re-pointing

Method 2: Direct Treatment (No Pressure Washing)

  1. Dilute 1 part Bio-Wash with four parts clean water
  2. Apply liberally over the entire contaminated area
  3. Leave for 7 days
  4. Brush, scrape, or gently hose clean
  5. Ideal for delicate surfaces like soft brick or friable stone

Coverage

  • One 5L container treats up to 125m²
  • Approximately equivalent to two average UK driveways
  • Highly cost-effective for large-area treatments

Professional Applications

Bio-Wash is commonly used as pre-treatment for:

  • Water-seal or surface water repellent applications
  • Re-pointing weathered masonry
  • Re-rendering earth-retaining walls
  • Masonry paint application
  • Paving resin sealer application

Proper surface sanitisation improves adhesion and longevity of protective treatments, preventing costly delamination of paint or sealers caused by organic growth.

Important Usage Notes

Safety & Application:

  • Do not apply at temperatures below +6°C
  • Avoid contact with metal or anodised finishes
  • Never use in a pressure washer soap reservoir
  • UV light activation required – better results in spring/summer
  • Use a garden sprayer, not an atomiser

Best Results:

  • Annual maintenance prevents damaging organic buildup.
  • Particularly effective for low-traffic areas under tree canopies
  • Essential preparation step for any protective coating application
