IZOMAX® C75 Flex
IZOMAX® C75 Flex is a two-component, fully elastic, cement and polymer emulsion based waterproofing material designed for demanding conditions involving temperature fluctuation and water pressure.
Complies with class CMO2P according to EN 14891.
CM: Cementitious waterproofing material applied in liquid form
O2: Crack-bridging ability (-20°C)
P: Bond strength in chlorinated water
Areas of Application
• Indoor and outdoor areas, on horizontal and vertical surfaces
• Wet and water-exposed areas such as bathrooms, kitchens, terraces, and balconies
• Swimming pools and water tanks
• Walls and floors of cold storage facilities
• Waterproofing applications beneath ceramic tiling
• Foundations and retaining walls
Advantages
• Easy to prepare and apply
• Fully elastic structure; does not shrink or crack
• Waterproof, with a water penetration resistance of 7 bar
• Provides excellent adhesion to the surface
• Waterproof yet vapour-permeable
• Can be applied with a brush, trowel, or sprayer
• Resistant to freeze-thaw cycles
