Frequently asked questions
How should the subfloor be prepared for this hob?
Level the subfloor using a tile screed or leveller to ensure full, even contact with the hob. Minor adjustments can be made with shims if necessary to achieve a stable base.
Can this hob be used for all wet area applications?
This hob is designed for perimeter barriers in wet areas like showers. It requires full waterproofing prior to tiling and is not intended for structural load-bearing applications.
Is this hob compatible with waterproofing membranes?
Yes, it works with both liquid-applied and sheet waterproofing systems. Ensure the hob surface is clean and dry before membrane application for optimal adhesion.
What is the best way to cut the polyurethane hob?
Use a fine-toothed handsaw or a power saw with a clean blade for precise cuts. Mark your measurements clearly before cutting to ensure accuracy and reduce waste.
Applications and benefits
| Application | Key benefit | Primary trades |
|---|---|---|
| Shower hob construction | Forms a compliant, stable perimeter for AS 3740 wet area waterproofing, reducing the labour and weight of traditional masonry. | Waterproofers, Tilers, Builders |
| Wet-area edge formation | Provides a consistent, straight edge that integrates cleanly with liquid and sheet membranes, ensuring effective water containment. | Waterproofers, Tilers |
| Base edge for step-downs | Creates a defined, stable barrier for screeded floors in recessed areas, maintaining consistent levels and supporting waterproofing continuity. | Builders, Tilers |
How to apply Hob Polyurethane 1200mm x 75mm x 50mm:
- Clean and level the subfloor surface where the hob will sit
- Measure and cut the hob to required length using a saw
- Secure in place with polyurethane construction adhesive
- Allow adhesive to cure before applying waterproof membrane
- Tile and grout as normal once waterproofing is complete
Product limitations
- Not for: Structural load-bearing applications. This product functions as a perimeter barrier, not a structural support.
- Waterproofing: Must be fully waterproofed prior to tiling. This hob is an element within a complete waterproofing system, not a standalone barrier.
- Storage: May deform under high-heat conditions if improperly stored. Keep in a cool, dry place away from direct sunlight.
Safety and handling
Personal protective equipment
Wear gloves and eye protection when cutting the material to prevent injury from dust or debris.
Ventilation
Work in a well-ventilated area when using power tools for cutting to minimise dust inhalation.
First aid
- Inhalation: If dust is inhaled, move to fresh air. Seek medical attention if irritation persists.
- Skin contact: Wash skin thoroughly with soap and water.
- Eye contact: Rinse eyes continuously with water for several minutes. If irritation persists, seek medical advice.
Storage and disposal
Store in a cool, dry place, protecting it from direct sunlight and high temperatures to prevent deformation. Dispose of offcuts and damaged sections with general construction waste. Do not burn the material. Always follow local environmental disposal guidelines.
Substrate guide
Proper substrate preparation ensures a stable foundation for the hob and reliable performance of the overall waterproofing system.
Concrete floors
Surface prep: Ensure the surface is clean, dry, and free from contaminants. Level any significant unevenness using screed or leveller. If required by the chosen adhesive, prime the concrete surface.
Primer: Optional, based on adhesive selection.
Compressed fibre cement
Surface prep: Ensure the surface is clean, dry, and stable. Verify a strong mechanical bond can be achieved with the chosen adhesive.
Primer: Optional, based on adhesive selection.
Timber substrates
Surface prep: Install over a waterproof board or screed system to provide a stable, moisture-resistant base. Ensure the underlying timber is structurally sound and prepared according to the board or screed manufacturer's specifications.
Primer: Not required for the hob itself when installed over a prepared waterproof board or screed. Adhesion will be to the board or screed system.
