When treating exterior walls for mould, algae, or fungi, Ceresit CT99 provides a professional-grade, deep-penetrating treatment to eradicate organic growth right at the root.
However, cleaning the wall is only the first step. For the most durable and long-lasting finish, CT99 is designed to work perfectly as part of a complete Ceresit exterior system:
✅ Step 1: Ceresit CT99 Anti-Mould: Eradicate moss, mould, and algae completely before any rendering begins.
✅ Step 2: Ceresit CT16 or CT17 Primer: Seal the newly cleaned substrate to create the perfect grip for your basecoat.
✅ Step 3: Ceresit Silicone Renders (like CT74): Apply a highly breathable, water-repellent topcoat that actively protects the masonry from future weather damage.
