This standard specifies the requirements, composition, and application methods for bitumen mastic used as a jointless flooring material. Engineers use this code to specify heavy-duty, damp-proof, and dust-free flooring in industrial, commercial, and residential buildings.
Bitumen-Mastic for Flooring
Quick Reference Values
Application temperature170°C to 200°C
Typical thickness for domestic flooring15 mm
Typical thickness for industrial flooring25 mm to 50 mm
Bitumen content (by weight)9% to 15%
Practical Notes
Ensure the concrete base is thoroughly dry and properly primed before laying the mastic; entrapped moisture will cause blistering.
Overheating the bitumen mastic during cooking (above 200°C) must be avoided to prevent degradation of the binder.
Joints in successive bays should be properly staggered and hot-merged to ensure a completely seamless and water-tight floor.
