Biocide treatments, also known as soft-washing, are essential for maintaining the cleanliness and integrity of various surfaces, particularly in residential and commercial properties, such as roofs. However, many people expect instant results, which is a common misconception. Here is a description on how biocide treatments work, the factors influencing their effectiveness, and the expected timelines for seeing results.

Understanding these elements can help property owners make informed decisions and manage their expectations regarding biocide applications.
Key Takeaways

• Biocide treatments take time to show results, typically requiring days rather than instant effects.
  Initial improvements may be visible within hours, especially for certain stains.
• Some surfaces may need a second treatment for stubborn stains, particularly if there is significant algae build-up.
• Unlike power washing, biocide treatments are gentler and less likely to damage surfaces.
  Proper surface preparation and care after treatment can enhance the longevity of the results.

 

Understanding Biocide Treatments

What are Biocide Treatments?
Biocide treatments are special chemicals designed to kill or control harmful organisms like bacteria, mould and algae. These treatments are essential for keeping surfacers clean and safe. They are often used in various cleaning processes to prevent the growth of unwanted plants and organisms.

How do Biocide treatments work?

Biocide treatments work by disrupting the cells of harmful organisms. When applied, they penetrate the surface and effectively eliminate existing growth. This process not only cleans the area but also helps to prevent future infestations. Here’s how it generally works:

1. Application: The biocide is sprayed onto the surface.
2. Penetration: It seeps into the material, targeting the cells of the organisms.
3. Elimination: The organic matter and organisms are killed leaving the surface clean.

Common types of Biocides:

There are several types of biocides used for different purposes. Here are a few common ones:

• Sodium Hypochlorite: Often used in cleaning and disinfecting.
• DDAC(Dodecyl Dimethyl Ammonium Chloride): Effective against a wide range of organisms.
• Benzalkonium chlorides(BACS): Also effective against a wide range of organisms.

Biocide treatments are not just for cleaning: they also play a vital role in preventing future growth, making them a valuable tool in maintenance.

Factors Affecting Biocide Treatment Results

Surface Material and Porosity
The type of surface being treated plays a significant role in how effective a biocide treatment will be. Porous materials like wood or concrete absorb the biocide better then non-porous surfaces such as metal or glass.

• Porous surfaces allow deeper penetration of the biocide.
• Non-porous surfaces may require more frequent applications.
• Different materials may react differently to the same biocide.

 

Environmental Conditions

The environment where the treatment is applied can greatly influence the results. Factors such as temperature, humidity and sunlight exposure can affect how quickly and effectively the biocide works.

• High humidity can enhance the effectiveness of biocides.
• Direct sunlight may cause the biocide to dry too quickly, reducing its effectiveness.
• Rain shortly after application can wash away the treatment, leading to poor results.

 

Expected Timeline for Biocide Treatment Results

Biocide treatments can show initial changes within just a few hours after application. This quick response is often due to the immediate action of the biocide on existing biofilms and surface contaminants. After a few days you can expect to see more noticeable results. Typically, the following changes occur:

• Reduction in visible algae and moss
• Discolouration of surfaces may begin to fade.
• Surfaces start to appear cleaner and brighter.

The long-term effects of biocide treatments can help with the lifespan of the surface.

After applying biocides keep people off the surface for at least 24 hours. In some cases a single biocide treatment may not be enough. Regular maintenance every few years will significantly improve the effectiveness of biocide treatments, ensuring long lasting results.

Comparing Biocide Treatments to Other Methods

Biocide vs. Power Washing

Biocide treatments and power washing are two popular methods for cleaning surfaces.

• Effectiveness: Biocides kill living organisms like moss and Algae, while power washing removes dirt and debris
• Speed: Power washing provides immediate results, whereas biocide treatments may take weeks to show full affects.
• Surface Damage: Power washing can damage delicate surfaces, while biocides are generally safer for most materials.

Advantages of Biocide Treatments

• Targeted Action: They specifically target harmful organisms, ensuring effective cleaning.
• Reduced Regrowth: Many biocides prevent future growth, leading to less frequent treatments.
• Versatility: Biocides can be used on various surfaces, including driveways, roofs, walls, render, patios, decking and fencing.

 

Summary

Biocide treatments(also known as Soft-Washing) are a powerful tool in maintaining clean and safe environments and with regular maintenance will help to prevent the growth of unwanted plants and organisms.
