MasterSeal 7000CR

The Solution for Extreme Wastewater Challenges

The concrete infrastructure of wastewater treatment systems is subject to complex physical and chemical attacks. MasterSeal 7000 CR is specially designed to address these challenges.

Unique Combination of Application and Performance Properties

MasterSeal 7000 CR’s high resistance to abrasion and biogenic sulfuric acid corrosion are ideal to withstand the severe conditions that occur in pretreatment and aeration tanks, digesters, or sewers. Its dynamic and static crack-bridging abilities protect concrete from cracks thus prolonging the structure’s life cycle.

Proven durability

Product properties
  • Fast and easy application by rolling or spray at temperatures from 5oC to 35oC
  • Excellent curing properties, which reduce downtime
  • Specific chemical resistance, including high concentrations of biogenic sulfuric acid
  • Crack-bridging for gaps of up to 0.7 mm
  • Maximum moisture tolerance, including application on humid substrates
Fast and Easy application – even on humid substrates

The easy application of MasterSeal 7000 CR by spray or roller, as well as its compatibility with damp substrates, suit the conditions of wastewater facilities particularly well. Downtime – which is always critical when stopping a wastewater process – is also reduced because of its fast-curing properties that allow contact with water only 24 hours after application at 20oC.
