Render Cleaning

Render Cleaning & Algae Treatment in Ireland

Render surfaces across Ireland are highly prone to algae growth, staining, and discolouration due to constant moisture and limited drying conditions.

Softwash Ireland provides professional render cleaning solutions using low-pressure softwashing treatments powered by AlgoClear — designed to treat organic growth at its source and restore the appearance of render safely and effectively.

Why Render Becomes Stained

Render is a porous surface, which makes it particularly susceptible to:

Green algae growth
Red and pink staining
Black streaking and discolouration
Atmospheric pollution and deposits

These issues are common across Ireland and tend to worsen over time if not treated correctly.

A Safer Alternative to Pressure Washing

Traditional pressure washing can damage render by:

Forcing water into the surface
Removing protective coatings
Causing uneven cleaning or patchiness

Softwashing avoids these risks.

Instead of aggressive cleaning, a specialist treatment is applied at low pressure, allowing the solution to penetrate the surface and treat the root cause of contamination.

How Render Softwashing Works

The process involves applying a controlled biocide treatment to the affected render surface.

This treatment:

Penetrates the porous surface
Breaks down algae and organic growth
Targets biofilms at a microscopic level
Continues working after application

Rather than delivering an instant cosmetic clean, the surface improves gradually as natural weathering removes the dead organic material.

Understanding Different Types of Staining

Not all render staining is the same, and different types of contamination require different expectations.

Green Algae

The most common issue. Typically treated effectively with softwashing, with visible improvement over time.

Red or Pink Staining

Often caused by specific types of airborne algae. While treatment kills the growth, full removal may take longer and depends on environmental exposure.

Black Streaks (Metabolites)

These are by-products left behind by organic growth. In some cases, additional treatment may be required to fully remove these marks.

Atmospheric Pollution & Efflorescence

Some staining is caused by environmental factors rather than organic growth. These may require different or additional approaches depending on severity.

Long-Term Results, Not Just Instant Cleaning

One of the key advantages of softwashing is that it focuses on long-term improvement.

Once the treatment is applied:

Organic growth is eliminated at source
Surfaces gradually clean over time
Regrowth is slowed significantly
Maintenance frequency is reduced

This makes softwashing particularly suitable for render surfaces where aggressive cleaning can cause damage.
