Repair mortar for voids from 5 – 40
mm, maximum grain: 2 mm
INDUCRET-BIS 5/40 is an anti-sag repair mortar for voids from 5 – 40 mm.
Main uses :
INDUCRET-BIS 5/40 is used as an antisag re-profiling mortar for vertical, horizontal and overhead areas for voids up to 40 mm. Use for concrete restoration areas under dynamic load (e.g. under roadbeds and concrete parapets).
Technical data :
Application Guide Direction:
- Surface preparation :
Before application of INDUCRET BIS 5/40 exposed steel reinforcement must be prepared with the corrosion protection INDUCRET BIS 0/2 in accordance with the product instructions. Cementitious surfaces must be solid with a good key and be load bearing , free from cement laitance , loose particles as well as adhesion inhibiting substances (oil , grease ,rubber marks , paint residues or other contamination).
Surface preparation is necessary such as e.g. grit or shot blasting , high-pressure water jetting , scabbling or planning. The substrate is to be intensively pre-wetted but during application of INDUCRET BIS 0/2 the relevant substrate may however only be matt damp.
Average surface tensile strength : min 1.5 N/mm2
- Product preparation :
1. Production of the repair mortar:
Partly fill a mixing vessel with up to 3 /4 of the above mentioned water quantity. Add the aforementioned quantity of INDUCRET-BIS 5/40 under constant stirring with a suitable stirrer (approx. 300 rpm). Thoroughly mix for 3 – 5 minutes to a lump free mortar. Add the remaining water and mix for a further 2 minutes. Use a forced paddle mixer for preparing large quantities. Only mix as much material as can be used within the aforementioned timings.
Hand trowel, wood float, steel lath, hand smoother, rubbing board.
INDUCRET-BIS 5/40 may only be used in combination with the bonding agent INDUCRET-BIS 0/2. Bonding agent:
Brush the INDUCRET-BIS 0/2 with a hard broom into the prepared matt damp substrate ensuring complete coverage and the pores are filled.
Subsequent application of the repair mortar INDUCRET-BIS 5/40 must be into the wet bonding agent. Spread the INDUCRETBIS 5/40 onto the fresh bonding agent to the required thickness with a suitable tool. Subsequently compact the mortar and smoothen.
Material consumption (finished mix):
Approx. 1.8 kg/m2/mm thickness,
approx. 1.0 litre/ mix = 2.13 kg
Protect the surface for at least one day after application of the INDUCRET-BIS 5/40 using suitable measures (e.g. covering with polythene) against rapid drying out resulting from direct sunlight, draughts and/or high temperature fluctuations.
Health and safety:
INDUCRET-BIS 5/40 contains cement that forms an alkaline reaction with moisture. Therefore contact with the eyes and skin is to be avoided and mortar splashes are to be thoroughly washed off immediately with plenty of water. Seek medical attention from an eye specialist when in contact with the eyes. Please store INDUCRET-BIS 5/40 out of the reach of children.
