What is Biocide Treatment (Bio-Treatment)?

Biocide Treatment, also known as Bio-Treatment, is a highly effective method for treating organic growth such as lichen, algae, and moss on exterior surfaces.

Unlike soft washing, it doesn’t clean the surface directly—it kills the organic matter, stopping it from regrowing and keeping surfaces cleaner for longer.

It's a low-maintenance, long-lasting solution ideal for busy homeowners or delicate surfaces.

How Does It Work?

The treatment kills organic growth like lichen, algae, and mold at the root.
Every time it rains or the surface gets wet, the treatment reactivates, continuing to work over time.
Within 24 hours, lichen starts turning brown.
Full results appear within 6–12 months, as the dead growth naturally falls off.

Benefits of Biocide Treatment

Long-Lasting Results
– Keeps surfaces clean for years without frequent reapplication.

Soft on Delicate Surfaces
– No high pressure—rain and wind do the work over time. Great for soft materials.

Safe for Timber
– pH neutral; won’t damage or stain untreated wood or other delicate surfaces.

Cost-Effective
– Cheaper than pressure washing or soft washing, especially for roof lichen and algae.

Best Surfaces for Bio-Treatment

Roofs
– Especially effective for lichen, algae, and moss on tiles, Colorbond, and shingles.

Soft & Delicate Surfaces
– Ideal for untreated timber, soft render, or surfaces that could be damaged by pressure.

Problem Areas
– Perfect for spots with recurring growth that always comes back after cleaning.

When to Reapply?

Generally a one-time treatment lasting several years.
Reapply only when organic growth visibly starts to return.

Why Choose Bio-Treatment?

Non-invasive and safe – No harsh pressure or chemicals
Let nature help – Wind and rain naturally clear debris
Highly effective – Targets growth at the source
Cost-saving – Avoid repeat pressure cleans
