Maxseal Flex M is a single-component, less flexible waterproofing mortar based on special cements, graded aggregates, and advanced additives. Once mixed with water, it forms a highly durable, seamless, and elastic coating suitable for both positive and negative side waterproofing of concrete and masonry. This product guarantees robust protection even under severe hydrostatic pressure and harsh environmental conditions.
Benefits:
Creates a seamless, flexible coating capable of bridging microcracks and shrinkage cracks (>0.5 mm)
Works as an anti-fracture membrane between the substrate and finishes
Exceptional resistance to carbonation, chlorides, sulfates, freeze/thaw cycles, and atmospheric pollution
Permeable to water vapor, allowing the structure to breathe while remaining waterproof
Highly resistant to abrasion and UV radiation
Suitable for aggressive environments: marine, wastewater, saline, and industrial
Certified for potable water contact, non-toxic and chloride-free
Excellent adhesion without primers; fills and seals substrate pores
Long-lasting durability with virtually zero maintenance
Resistant to root penetration
Easy to apply by brush, roller, trowel, or spray
Cement-based and solvent-free environmentally friendly
Applications:
Waterproofing and protecting water retention structures (tanks, reservoirs, canals, pools, fountains)
Interior and exterior waterproofing of basements, elevator pits, tunnels, and structures under hydrostatic pressure
Protection of concrete in water treatment and purification plants
Waterproofing of foundations, retaining walls, and structures below grade, even with aggressive water/soil exposure
Roofs, terraces, balconies, and planters (exposed or under tile/soil)
Interior waterproofing of bathrooms, kitchens, and wet areas in commercial or residential buildings
Yield and Presentation:
Supplied in 22 kg bags (white or grey). Typical consumption: 1-1.5 kg/m2 per coat, with a total of 2-3 kg/m2 applied in two coats.
Warranty:
10 years when applied according to the official technical sheet and recommended practices.
Compatibility:
Compatible with Drizoro Mesh 58 for reinforcement of joints and cracks; compatible with Maxrest Passive for rebar protection.
Application Tips:
Apply on a solid, clean, slightly damp surface. Mix only with water as directed. Apply two perpendicular coats using a brush, roller, trowel, or spray. Embed Drizoro Mesh between coats for cracks/joints. Allow at least 6-8 hours between coats; avoid rain or temperatures below 5C for 24 hours post-application. Protect against rapid drying with wet cloth or plastic if needed.
Warnings:
Do not add other cements, additives, or aggregates. Do not use on hydrophobic, bituminous, or resin-coated surfaces. Do not use in structures that present movement or are exposed to temperature dilation, for that, use Maxseal Flex. Always use gloves and goggles and avoid inhaling dust or contact with skin/eyes.
