Remove Black Mold from Walls Safely - The Bio-Based Way

MoldEx is a bio-based, chlorine-free solution that removes black mold (black mould) completely and safely. Unlike harsh bleach products, it doesn’t just lighten the stains — it destroys the mold at its roots. The best part? You don’t need gloves, masks, or special equipment.

This article explains how to use MoldEx effectively, what makes it different, and how to keep your walls mold-free long term using complementary Logic Sept and Logic Chemie solutions.

Why Choose MoldEx

When it comes to removing mold, safety and effectiveness should go hand in hand. MoldEx offers both:

• Bio-based and chlorine-free: no aggressive chemicals or strong bleach fumes.
• No PPE required: safe for everyday home use; gloves are optional for very sensitive skin.
• Deep-pore cleaning: MoldEx penetrates surfaces, eliminating mold instead of covering it.
• Surface-friendly: suitable for painted, plastered, or mineral walls and ceilings.

MoldEx doesn’t mask the problem — it removes the cause.

Preparation Before Cleaning

A few minutes of preparation can make your treatment more effective:

• Painted walls: remove any loose or flaking paint so the product can reach the wall surface.
• Silicone joints and corners: cut away old silicone before cleaning. Mold often hides underneath it. After cleaning, reseal joints with Logic Silicone for long-term protection.
• Ventilation: open a window or door for normal air circulation. No special ventilation is needed, but airflow helps drying later.

How to Use MoldEx

1. Spray generously on all visible mold and the surrounding area. Make sure the surface is evenly wet.
2. Wait 3–4 hours. MoldEx will slowly penetrate the pores and break down mold growth.
3. Clean and rinse. Use a soft sponge to remove the residue and rinse with clean water.

Aftercare and Long-Term Prevention

MoldEx removes the existing mold completely, but whether it returns depends on environmental conditions. To prevent recurrence, you need to keep the area dry and address the source of moisture.

• Bathrooms: ensure ventilation and re-seal joints with Logic Silicone after cleaning. For full guidance, read Get Rid of Shower Mold with MoldEx. You can also use Logic S on stone or concrete surfaces in the bathroom — it prevents mold from growing again for a long time and keeps the area water-repellent and easy to maintain.
• Basements and damp walls: leaks or rising damp often cause recurring mold. Treat the wall with Logic Water, a deep-penetrating waterproofing system that blocks moisture.
• Home humidity: maintain humidity below 60%. Use fans, open windows, or dehumidifiers.

Once you control humidity and protect vulnerable surfaces, MoldEx keeps your walls clean and bright for years.
