Eradicating Black Spot Problems

Eradicating Black Spot Problems – At Protech Property Solutions, we take pride in delivering top-tier cleaning and maintenance services to property professionals across London and the Home Counties. One issue we often encounter during pressure washing is the appearance of stubborn “black spots” on paving and hard surfaces. Understanding what these black spots are, why they persist, and how to deal with them is key to maintaining the aesthetic and functional value of your properties.

What Are Black Spots?

Black spots, also known as lichen, are tiny but tenacious organisms that attach themselves to outdoor surfaces such as paving slabs, brickwork, and concrete. Lichen thrives in damp and shaded conditions, making many areas of communal spaces in blocks of flats particularly susceptible. Over time, these spots form a tough, black crust that bonds tightly to the surface, making them highly resistant to standard cleaning methods.

The issue is not merely cosmetic. Left untreated, black spots can:

• Diminish the appearance of communal areas, potentially affecting property value.
• Pose safety hazards by contributing to slippery surfaces.
• Accelerate surface degradation, leading to costly repairs or replacements.

Why Do Black Spots Persist After Pressure Washing?

While pressure washing is highly effective at removing dirt, algae, and surface grime, it often fails to eliminate black spots. This is because:

1. Strong Adhesion: Lichen anchors itself deeply into the pores of paving materials.
2. Resilience: Lichen has a robust outer layer that withstands high-pressure water.
3. Growth Cycle: Pressure washing can remove the visible surface layer of lichen but leave behind microscopic fragments, which can regrow over time.

How Protech Property Solutions Tackles Black Spots

At Protech Property Solutions, we employ specialised methods to ensure your outdoor surfaces remain spotless and safe. Our approach includes:

Pre-Treatment

Before pressure washing, we apply a specially formulated biocide or lichen remover. This treatment breaks down the tough outer layer of the lichen, weakening its grip on the surface.

Targeted Pressure Washing

Once the biocide has had time to work, we use professional-grade pressure washing equipment to thoroughly clean the area. Our technicians are trained to adjust water pressure and temperature to suit the surface material, ensuring effective cleaning without causing damage.

Post-Treatment Care

To inhibit regrowth, we apply a protective sealant or an additional layer of biocide. This creates a barrier against moisture and organic growth, keeping surfaces cleaner for longer.

Benefits for Property Managers

Investing in professional black spot removal has several advantages for property managers:

• Enhanced Kerb Appeal: A spotless exterior creates a positive impression for residents and visitors alike.
• Cost-Effective Maintenance: Preventative care reduces the need for expensive repairs and replacements.
• Safety Compliance: Clean, slip-free surfaces help you meet health and safety standards, avoiding potential liability issues.
