Hob Polyurethane is a high-density polyurethane foam perimeter solution designed for professional wet area waterproofing and shower hob construction. This dimensionally stable profile weighs approximately 500g per unit, significantly reducing labor fatigue in multi-story residential fit-outs while maintaining the rigid edge required for precise tile alignment.
Engineered for full compatibility with liquid and sheet membranes, it ensures a continuous seal to prevent capillary action and meet AS 3740 and NCC wet area requirements. Installers must ensure the substrate is level using tile screed or base leveller and avoid direct installation onto raw timber to prevent delamination or moisture ingress.
While providing a mechanical bond for tiling systems, this profile is not rated for structural load-bearing glass hardware and must be fully waterproofed prior to finishing to maintain watertight integrity.
Frequently Asked Questions About Hob Polyurethane 1200mm x 75mm x 50mm
Q: How do I cut the polyurethane hob?
A: Use a fine-toothed handsaw or a power saw with a clean blade for precise cuts. Always mark your measurements clearly before cutting to ensure accuracy on site.
Q: Will this hob support tiling and grout properly?
A: Yes, the hob is designed for full tiling systems and provides a stable base once waterproofed, allowing tiles and grout to adhere securely without movement.
Q: Is it compatible with liquid or sheet waterproof membranes?
A: Absolutely. This hob works well with both liquid-applied and sheet membrane systems. Ensure the surface is clean and dry before applying the membrane.
Q: What if the subfloor is uneven?
A: Level the area using tile screed or base leveller prior to installation. Shimming may be used for minor adjustments to ensure even contact along the full length.
Q: How do I dispose of offcuts or damaged sections?
A: Offcuts can be disposed of with general construction waste. Avoid burning the material, and always follow local disposal guidelines.
