Application

Used in waterproofing applications where contact with potable water or a high level of chemical resistance is required.

  • Water towers, storage tanks or any other water retaining structures.
  • Interior coating to drinking water tanks.
  • Storage tanks containing foodstuffs etc.
  • Waste water treatment plants (commercial and industrial), both in the inflow and outflow areas.
  • Sewage effluent pipelines.
  • Steel and concrete pipes.

Additionally it can be applied on:

  • Horizontal and vertical substrates.
  • Internal and external areas.
  • Concrete, cementitious mortar or steel substrates.
  • Reinforced concrete to protect it against carbonation or chloride induced corrosion and for protection against chemical attack in secondary containment bunds in chemical and petrochemical industries.

Description

MasterSealM 808 is a two component, 100% solids, elastic polyurethane membrane, with high chemical and abrasion resistance. Approved for direct contact with potable water and foodstuff.

Features and benefits:

  • Regulation 31 approved. (Regulations 2014, 33 (3 a) in Scotland and Regulation 30 in Northern Ireland).
  • WRAS approved for use in contact with potable water, approval 1210500.
  • Can be applied on vertical and horizontal surfaces.
  • Easy to apply by roller or air-less spray equipment.
  • Resistant to standing water.
  • Elastic, flexible and crack bridging.
  • Protects concrete against carbonation and rebar corrosion: Once hardened it is impermeable to water and carbon dioxide.
  • High chemical resistance.
  • Excellent adhesive, mechanical and elastic properties (elongation, tensile and tear strength, abrasion).
  • Excellent freeze/ thaw resistance.
  • UV resistant.
  • 100% solids formulation, no risk for the environment and operative caused by solvent vapours.
  • CE marked.
