Which Biocide Should I Use?

Quick Answer: The most suitable biocide depends on the surface being treated, the type of contamination present, environmental conditions and the objectives of the maintenance programme. Professional contractors typically select products based on site-specific requirements rather than using the same product for every project.

Why Is Choosing The Right Biocide Important?

Different properties, surfaces and environments present different challenges.

A roof affected by biological contamination may require a different approach from a rendered wall, paved area or commercial building.

This is why professional contractors usually assess the project before selecting a treatment product.

What Is A Biocide?

A biocide is a product designed to control biological organisms such as algae, fungi, mould and bacteria.

Within exterior cleaning, biocides often form part of wider cleaning and maintenance programmes.

Should Price Be The Main Factor?

Not necessarily.
