Mold and algae make stone and concrete surfaces slippery, unsightly, and even hazardous. They thrive in damp, shaded areas and can spread rapidly if not properly treated, creating stubborn green or black patches that damage your outdoor spaces and reduce safety.
Mold and algae don’t just sit on the surface — they penetrate deeply into microscopic pores and capillaries. This is why surface-level cleaning methods often fail, and regrowth happens quickly.
Bleach only removes surface discoloration temporarily and can damage plants, soil, and even the stone or concrete itself. High-pressure washing may push spores deeper into the material and roughen the surface, making it more prone to future infestations.
Logic Clean A is not just another cleaner — it goes beyond traditional nano-based formulas. Using ultra-fine particles smaller than nano (pico-level technology), it penetrates deep into the tiniest pores that other products cannot reach.
What truly sets this product apart from conventional mold and algae removers is its ability to reach the core of mold and algae, drying them from within and eliminating them completely at their root.
Logic Clean A is bio-based, eco-friendly, non-corrosive, and safe for surrounding plants and surfaces. It delivers powerful, thorough cleaning without the harshness of traditional chemicals, helping you keep your environment and surfaces healthier.

After cleaning, long-term protection is essential. Use Logic EX — an advanced, paraffin–polymer-based water-repellent coating — to seal exterior stone, concrete, and brick surfaces. It creates an invisible, breathable barrier that repels water, dirt, and moisture, preventing new mold and algae formation.
Logic EX penetrates deeply into the surface and provides durable hydrophobic protection that helps keep façades, terraces, stairs, and walls clean for years. It reduces moisture-related damage, cracking, and energy loss — offering up to 20 years of reliable waterproofing when applied correctly.

A heavily stained stone terrace treated with Logic Clean A showed dramatic improvements in just one day. Even deeply embedded algae and mold disappeared, leaving the surface clean, safe, and beautifully restored. After sealing with Logic EX, the terrace stayed spotless and water-resistant for over a year, with significantly reduced maintenance needs.
Combining Logic Clean A for deep biological cleaning with Logic EX for long-term exterior sealing ensures lasting results. Surfaces remain cleaner, safer, and more resistant to environmental wear. This dual treatment not only restores your property’s appearance but also extends the life of your stone and concrete structures.
