Is Plaster the Solution for Stopping Black Fungus and Mold from Growing on Your Walls?

Black fungus and mold creeping across your walls isn’t just an eyesore—it’s a sign that moisture and poor surface protection have given these invaders the perfect home. Whether renovating your house or safeguarding a new building, finding a reliable solution that keeps these harmful growths at bay is crucial. Plaster offers an expert-level shield, promising not only a pristine finish but also long-lasting protection against mold and fungus, so your walls stay beautiful and healthy in all seasons.

Why Does Black Fungus and Mold Appear on Walls?

Mold and black fungus thrive in damp, poorly ventilated environments. The most common scientific triggers include:

·       Water Seepage: Cracks or leaks allow moisture to seep into walls, creating a perfect breeding ground for spores.

·       Humidity and Temperature: Mold and fungus flourish when humidity levels exceed 60% and temperatures stay around 20–30°C. Warm, moist indoor air condenses on wall surfaces, supplying steady moisture.

·       Material Porosity: Highly porous surfaces absorb water and retain dampness. Cement plasters that are not water-resistant provide ample room for fungal colonization.

Fungi such as Aspergillus niger (black fungus) and other molds create webs of hyphae that digest organic molecules found in dust, paint, and construction residues. Their growth accelerates in the presence of persistent moisture, poor air circulation, and lack of sunlight. Over time, they break down wall finishes and can trigger health problems like allergies, asthma, or even more severe respiratory symptoms.

How Plaster Can Be the Solution

Modern ready mixed plaster like Birla White Levelplast creates a protective barrier between the wall surface and external moisture. But why exactly does good wall plaster stop fungus?

• Blocking Moisture Entry: Cement-based, polymer-modified plasters prevent water from filtering through the wall’s surface, stopping fungi from accessing the essential moisture they need to grow.
• Anti-Carbonation Properties: Carbonation can weaken the wall surface and promote micro-cracks. Anti-carbonation plaster resists this process, reducing vulnerabilities where mold could settle.
• Smooth, Dense Finish: A properly applied wall plaster leaves few pores or surface irregularities, denying spores the rough, porous environment ideal for anchoring and colonizing.

Birla White Levelplast’s Superior Protection

Birla White Levelplast stands out among wall plaster products because its formula is specially engineered for water resistance and anti-carbonation, making it the best cement for plaster where mold and fungal attacks are a threat.

Let’s break down what makes Levelplast so effective:

• Cement-Based, Polymer Modified: The white cement base resists absorption, while polymer modification increases flexibility and adhesion, protecting both new and old walls.
• High Water Resistance: Scientific testing shows Levelplast’s water capillary absorption is ≤0.80 ml at 28 days (Karsten Tube method), confirming its ability to repel water and shield against seepage—a primary trigger for mold.
• Compressive Strength and Dense Structure: With a high compressive strength  Levelplast is tough, reducing micro-cracks. A bulk density of 1.3–1.7 g/cm³ means fewer gaps for fungal invasion.
• Hacking and Curing Free: Unlike traditional cement plasters, Levelplast does not require hacking or curing, reducing weak spots that might otherwise collect water or dust.

Scientific Evidence Behind Anti-Fungal Performance

Walls covered with poor-quality plaster allow water ingress, which, in turn, encourages the formation of biofilms—microbial communities that foster fungal proliferation. The anti-carbonation property found in Levelplast slows down the penetration of CO₂ and moisture, stalling processes that would otherwise create fertile ground for fungal spores.

Furthermore, ready mixed plaster with dense microstructure blocks the capillary action that carries water upwards from floors or sideways from leaks, making interior and exterior application effective in preventing mold and black fungus.

Application and Results: Wall Plaster That Lasts

A well-plastered wall—using Birla White Levelplast—achieves:

• Uniform Coverage: Adherence on difficult surfaces (AAC, concrete, red bricks, ceilings), minimizing unprotected zones where mold might take hold.
• Sealed Cracks and Joints: Levelplast can repair cracks, holes, and joints, closing off major routes for moisture intrusion and fungal infestation.
• Long-Term Protection: With up to 12 months shelf-life and certified durability, this ready mixed plaster offers lasting defense on all types of surfaces.

Environmental and Health Advantages

Levelplast contains no added lead, mercury, or chromium compounds. It’s safe for both applicators and residents, when handled correctly. By keeping walls dry and free of black fungus and mold, Levelplast improves indoor air quality and helps prevent allergies, respiratory infections, and other health threats linked to mold spores.

How to Get the Best Results

• Surface Preparation: Remove all dirt and greasy residue, moisten walls, and follow directed thickness steps for optimal plaster performance.
• Finishing: Complete with 1–2 coats of Birla White putty for even greater resistance to fungal contamination.
• Precautions: Ensure surfaces are dry between coats, don’t apply during peak sun on exteriors, and protect eyes, skin, and lungs during use.

If stopping black fungus and mold is a priority, use only the best cement for plaster: Birla White Levelplast ready mixed plaster. It offers unmatched water resistance, anti-carbonation benefits, and a dense, even finish—all scientifically backed features that defend your walls against damaging fungal growth while promoting a healthier home.
