What Does Biocide Treatment Do?

When it comes to external surface cleaning and long-term maintenance, biocide treatment plays a vital role in removing and preventing the return of biological growth such as algae, moss, mould, and lichen. But what exactly does biocide treatment do — and how does a professional product like PureSeal BioClear Pro work?

Understanding Biocide Treatment

Biocide treatments are chemical solutions designed to kill and inhibit the growth of microorganisms. This includes common surface contaminants like green algae, black mould, and moss, which often thrive on roofs, render, driveways, and patios. These contaminants don’t just look unsightly — they can degrade surfaces over time and create slip hazards.

What is PureSeal BioClear Pro?

PureSeal BioClear Pro is a high-strength, professional-grade biocide with a 40% DDAC concentration. It’s a fully approved and licensed surface biocide (COPR No. 10854), designed for use by trained professionals. This powerful formula delivers a fast-acting treatment that breaks the reproductive cycle of microbial surface contaminants with just one coat.

Where Can It Be Used?

• Roof tiles and slates

• Rendered walls

• Paths, patios, and driveways

• Most exterior hard surfaces

It can be applied by brush or sprayer, depending on the surface and the size of the area being treated.

How Does It Work?

Once applied, BioClear Pro kills biological growth on contact. While results may vary depending on the surface, the environment, and the dilution used, its action is consistent:

• Instant kill of surface biofilm

• Prevention of regrowth by disrupting microbial reproduction

• Self-cleansing – allowing natural weathering to remove dead growth

On non-porous surfaces like porcelain or coated cladding, the treatment won’t last as long due to less absorption, but it will still eliminate biological growth effectively.

Recommended Dilution Rates

To get the best performance, it’s essential to dilute BioClear Pro correctly:

• Render & Roof Tiles (scraped): 1 part biocide to 20 parts water

• Ground Surfaces (driveways, paths, etc.): 1 part biocide to 40 parts water

Apply at a rate of 4m² per litre of diluted product. The exact ratio may vary depending on surface condition and porosity.

Safety Considerations

Because BioClear Pro is a professional-use biocide, HSE-approved training is required to apply it legally and safely. It’s also important to consider the safety of pets and children. After application:

• Leave the product on the surface for at least one hour

• Then rinse thoroughly to remove any residues

This step ensures peace of mind for your customers and protects their loved ones from potential harm.

Final Thoughts

Biocide treatments are a crucial part of any exterior cleaning process. They don’t just clean — they prevent regrowth, saving time and money in the long run. With a powerful, compliant product like PureSeal BioClear Pro, professionals can deliver outstanding results across a wide range of surfaces.
