What Causes Red & Green Algae?

Green algae commonly appears on:
 
  • House walls
  • Render
  • Patios
  • Driveways
  • Roofs
  • Fences
  • Decking
 
It thrives in shaded, damp environments and can make surfaces slippery, unsightly and difficult to maintain.
 
Red algae is becoming increasingly common on modern render systems, particularly silicone render, monocouche render and coloured render finishes.
 
It often appears as:
 
  • Red streaks on walls
  • Pink or red staining
  • Rust-coloured discolouration
  • Patchy red growth on render
 
Red algae can spread rapidly and significantly affect the appearance of a property if left untreated.

Why Remove Algae?

Algae growth is more than just a cosmetic issue.

Removing algae can help:

  • Improved kerb appeal
  • Protect property value
  • Reduce slip hazards
  • Improve appearance of render
  • Maintain exterior finishes
  • Enhance first impressions

Early treatment often prevents more extensive cleaning work later.

Our Safe Wash Cleaning Process

At Soft Washing UK, we use specialist low-pressure application methods to apply Safe Wash to affected surfaces.

Our process typically includes:

  • Inspection of the affected area.
  • Assessment of algae contamination.
  • Application of Safe Wash organic cleaner.
  • Treatment of red and green algae growth
  • Gentle rinsing or natural weathering process where appropriate.
  • Final inspection.

This approach helps achieve effective cleaning results while protecting delicate exterior surfaces.

Surfaces Suitable for Safe Wash Treatment

Safe Wash can be used on a wide variety of exterior surfaces, including:

  • K Rend
  • Monocouche render
  • Silicone render
  • Coloured render systems
  • Brickwork
  • Stonework
  • Timber cladding
  • Fencing
  • Decking
  • Patios
  • Driveways
  • Garden walls
  • Commercial buildings

This approach helps achieve effective cleaning results while protecting delicate exterior surfaces.

Safe Wash provides an ideal cleaning solution for:

  • Red algae on render

  • Environmental contamination

Because the product is organic and applied using low-pressure techniques, it helps reduce the risk of damage associated with aggressive cleaning methods.
