HydroFort™ PU Polyurethane

HydroFort™ PU is a highly elastic, class 3, single component, liquid applied, polyurethane waterproofing membrane system that complies with AS/NZS 4858. HydroFort™ PU forms a tough, durable membrane that bonds well to most suitably primed building substrates and is suitable for above and below ground applications.

Description

It is designed for waterproofing diverse parts of a building including.

  • Balconies
  • Terraces
  • Podium decks
  • Bathrooms and wet areas
  • Plant room floors
  • Inverted roofs
  • Undertile bed

Applications

HydroFort™ PU is designed to be applied by either brush or a roller. 2 coats of 0.5 - 0.6 litres /m2 are required to achieve a dry film thickness of 1.2 mm. Light foot traffic is achieved after 24 hours. HydroFort™ PU will discolour and chalk on the surface in direct sunlight without effect of properties. It is recommended to top coat with non yellowing polyurethane where these affects are to be prevented.

Surfaces

Ensure surface are clean, sound, smooth and dust and oil-free. A layer of diluted HydroFort™ PU (with 10% Solvent X) can be used as a primer for dry and contaminants-free concrete. In the case of high porosity or slightly damp substrates it is recommended to use HydroFort™ VB epoxy vabour barrier primer in accordance to the product datasheet.
