1. Apply a first coat of LANKO 731 STRUCTURE REPAIR with a trowel, pressing firmly to ensure effective bonding, building up to required thickness in one single operation. A maximum thickness is 35 mm.
2. The case of repairing the corner of the concrete column, use 2 trowels on each side of the corner to prevent over use of mortar on the corner.
3. Apply additional mortar to obtain the desired overall thickness. Smooth the surface with a trowel or float the repaired surface for a smooth finish.

After finishing, protect the mortar from drying out by applying LANKO 361 CURE.
