Overview
Ultibed Mortar 60 is a rapid-setting bedding mortar formulated to achieve a typical return-to-service time of approximately 60 minutes at ambient temperatures around 18–22°C. It is specified for applications requiring fast early strength gain and compliance with National Highways HD 27/15.

Applications

• Laying setts (bedding mortar for paving setts)
• Installation of street furniture
• Inspection chamber and manhole reinstatement
• Manhole cover and inspection frame installations
• Stanchion and post installation
• Gully grate and drain cover installation
• Laying kerb stones

Key benefits

• Rapid return to service: typical traffic-ready time ~60 minutes at ~18–22°C
• High early and high final compressive and flexural strength (see technical data)
• Strong bonding to substrates without requirement for a primer
• Factory blended under quality procedures in accordance with BS EN ISO 9001
• Easy to mix on site; mechanical mixer recommended
• Workability typically 5–10 minutes after mixing
• Available in 25 kg water-resistant bags and tubs; vacuum packed for extended shelf life
• Optional PLUS+ formulation with improved performance and reduced environmental impact

Usage & mixing
Mix one 25 kg bag with approximately 2.5–3.0 litres of clean, cool water. For best results, pre‑measure water and add powder to water, mixing for about 2–3 minutes until a smooth, homogeneous consistency is achieved. Recommended equipment: forced-action high shear mixer or slow-speed drill with paddle; hand mixing acceptable for small volumes. Typical workability: ~5–10 minutes. Clean tools and equipment immediately after use with clean water.
