Technical overview
Key applications
- Water retaining structures - water tanks, reservoirs, dams, water channels, fountains and swimming pools
- Potable water tanks
- Below-grade structures - basements, retaining walls, foundations, tunnels and galleries under high negative water pressure
- Wastewater treatment plants and settlement tanks
- External protection against aggressive water and ground salts below the water table
- Protection against weathering, carbonation, freeze/thaw cycles, de-icing salts and marine environments
- Roofs, terraces and balconies, in the open or under pavements
- Window boxes, gardens and other surfaces subject to root penetration
- Internal wet areas - bathrooms and kitchens in hotels, hospitals, offices and residential buildings
Surface suitability
- Concrete (solid, sound, rough, clean and free of paints, efflorescence, loose particles, greases, release oils, dust and plaster)
- Masonry (thoroughly saturated with water without forming puddles, coated once the surface has taken on a matt appearance)
- Smooth or poorly absorbent substrates (sandblasted or high-pressure water cleaned to an open texture surface)
Do not apply to water-repellent substrates, bituminous materials, plasters, or paints. Do not apply below 5C or if lower temperatures are expected within 24 hours after application, do not apply on frozen surfaces, and do not apply if rain is expected 24 hours after application. Avoid direct exposure to sunlight and extreme heat, and thoroughly wet the substrate in high temperatures, strong wind or low relative humidity. Do not add cement, admixtures, sand or any other compound, and never add more water to recover workability - remix instead. Do not mix product that cannot be applied within 20-30 minutes. Observe the minimum and maximum recommended consumptions. Keep the coating moist for at least the first 24 hours with wet burlaps and plastic sheets. Allow 3 days before covering with ceramic tile, plaster or earth and gravel, and 5 days before putting into service or water immersion at 20C and 50% RH. MAXSEAL FLEX-M is an abrasive compound classified Danger, H314 causes severe skin burns and eye damage, H317 may cause an allergic skin reaction and H335 may cause respiratory irritation - wear protective rubber gloves and goggles.

Frequently asked questions
-
What's the difference from Maxseal Flex?
CompatibilityMaxseal Flex M is single-component (just add water) where Maxseal Flex is two-component (resin + powder). Flex M is faster to mix and harder to get wrong on site, but slightly less flexible than the 2-component Flex.
-
What's the crack-bridging ability?
PerformanceMaxseal Flex M bridges cracks greater than 0.5mm wide - sufficient for typical substrate movement in residential and light commercial applications. For high-movement applications, use the 2-component Maxseal Flex.
-
Coverage and application?
InstallationApply 2.0-3.0 kg/m² total in two crossed coats at 1.0-1.5 kg/m² per coat. Use brush, roller, broom, or spray equipment onto a damp (not saturated) substrate.
-
Suitable for water tanks?
CompatibilityYes. Maxseal Flex M is rated for water-retaining structures including tanks, reservoirs, fountains, and pools. Resists positive and negative hydrostatic pressure.
-
CE marked?
ComplianceYes. Maxseal Flex M is CE marked with a published Declaration of Performance. Refer to the linked TDS for full test data.
Why trade professionals choose Drizoro
Drizoro is a Spanish manufacturer of cement based waterproofing and concrete repair products, supplied to the Australian trade through The Waterproofing Shop. The range on this site covers Maxseal Foundation and Maxseal Flex, along with repair mortars, grouts, joint products and mesh, used on concrete and masonry where water has to be held back rather than simply shed. Choosing between the rigid and the flexible grade is the key decision, and it comes down to the substrate, the direction of the water and how much movement the structure is likely to see.
