ADVANTAGES

  • Flexible
  • Waterproof
  • Suitable for light pedestrian traffic
  • High resistance to chloride ion diffusion
  • Non-toxic suitable for contact with potable water
  • Excellent adhesion. Bonds to porous and non- porous surfaces
  • Breathable - whilst repelling water, allows substrate to breathe
  • White color has high solar reflectivity index (SRI) to prevent heat island effect on roofs
  • Unlike conventional coatings which require a 7-28 day cure of concrete, MasterSeal 550 can be applied to 24 hour-old concrete thereby giving immediate protection

TYPICAL APPLICATIONS

  • As a waterproof coating for roofs.
  • For waterproofing of wet areas under tiling.
  • For use on pedestrian walkways in marine areas.
  • Sealing and coating tie bar holes to ensure watertightness.
  • As a waterproof and protection coating on top of spray polyurethane foam roof insulation.
  • As a backing to marble and granite to prevent water ingress and thus alleviate surface staining.
  • To provide foundation protection.
  • For coating seawater channels.
  • As a waterproof lining for water retaining structures.
  • To reface and even out variations in concrete surfaces.
  • For waterproofing and protection against brackish water.
  • To provide protection to concrete surfaces from carbonation and chloride attack.
