TECHNICAL DATASHEET
BIT 1702
Rubberized Bitumen Waterproofing
BIT 1702 is a thixotropic rubberized bitumen emulsion dries to provide a tough, seamless, flexible waterproof and vapour proof membrane coating. It forms a dark, thick coating that keys directly onto cementitious and brick surfaces.
TYPICAL APPLICATION
An economic system for the sealing and waterproofing of tanks, retaining walls, reservoirs and pools, floors and roofs, balconies, prestressed concrete slabs.
Use with POLYESTER FIBRE MEMBRANE for maximum protection
ADVANTAGES
• Earlier hardening and greatly improved flexibility
• Fast Setting
• Hard surface
• Good adhesion to concrete
• Easy application
• Resistant to chemicals and sulphates
• Water based
WATCH POINTS
• Keep surfaces from being exposed to water prior to BIT 1702 setting hard.
• Wash equipment immediately after use with water.
DIRECTIONS FOR USE
Surface Preparation:
Surfaces are to be clean, sound, and free of deleterious substances. Remove all laitance, oil, grease, mould oil or curing compound from concrete surfaces using wire brush, bush hammer, scabbler or other plant as appropriate. When repairing damaged concrete, ensure that all loose concrete has removed down to a firm base. Repair with PLAST 1038 or GROUT CEM 60. Surfaces can be damp but not wet.
Priming:
No priming is required
Application:
Apply with a sprayer or block brush or at a rate of 0.5mm thickness. Inset POLYESTER FIBRE MEMBRANE (if required). Allow to cure for 24 hours between coats. Apply a second coat. Target thickness is 1mm.
