MasterSeal 588
Application

  • Water retaining structures which may be subject to movement.
  • As part of the basement waterproofing system, in areas sensitive to movement, vibration and settlement.
  • To protect concrete from water of low pH or soft quality, carbonation and de-icing salts.
  • Suitable for internal and external use, against positive and negative water pressure.
  • As a resilient coating to protect concrete on bridge parapets, columns, piers, on land and in marine environments.
  • Waterproofing of new structures where movement is expected from drying shrinkage.
  • Once cured, the 2 mm thick membrane will accommodate up to 0.5 mm, or 1.5 mm of movement when reinforced with FX Mesh.

MasterSeal 588 is not suitable for prolonged contact with hydrocarbons such as petrol, fuel oil, etc.

Description

MasterSeal 588 powder and liquid when mixed forms a brushable waterproof slurry, which cures to a flexible elastomeric membrane. It is applied to a minimum 2 mm thickness in two coats by stiff brush, broom or spray.

Features and benefits:

  • Regulation 31 approved for use with potable water.
  • Retains flexibility when submerged.
  • Good chemical resistance against soft water, domestic and sewage waste water and other liquids moderately aggressive to mineral substrates.
  • Resistant to occasional foot traffic.
  • 2 mm of cured coating equivalent to 500 mm of concrete cover.
  • Freeze/ thaw resistant and water vapour permeable.
  • No solvent.
