- Plant room floors
- Inverted roofs
- Undertile bed
- 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
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.
