Waterproofing Membrane - HydroFort™ PU

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

Material

Polyurethane

Advantages

Seamless waterproofing membrane Permanently flexible Low odour / Low VOC High resistance to puncture and standing water Quick tack-free surface Low VOC High elongation, class III membrane according to AS/NZS 4858 Crack bridging capability, no reinforcement needed Single pack, ready to use TDI and Toluene free

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. Lightfoot traffic is achieved after 24 hours. HydroFort™ PU will discolour and chalk on the surface in direct sunlight without the effect of properties. It is recommended to topcoat with non-yellowing polyurethane where these effects are to be prevented.

Surfaces

Ensure surface is 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 vapour barrier primer following the product datasheet.
