The measured quantity of clean water (8.3 l) shall be poured into a clean vessel. Then the entire contents of the BAUBOND bag should be emptied into water, with simultaneous mixing for minimum 5 minutes with a mixer mounted on a slow rotation drill (400 rotations/minute). A homogenous mixture should be achieved (without lumps), which may thicken a little. The suspension should have adequate viscosity to allow desired spreading. During application it should be mixed from time to time.

The concrete surface shall be free of any contamination and loose parts, and the existing cracks and losses shall be repaired. The base may not be frozen. It is necessary to remove from the surface any oil stains etc., as well as tyre marks or surface markings. Concrete fragments with corrosion (e.g. chloride corrosion) are to be removed. Damage to concrete caused by corroding reinforcing steel shall be broken away, and all damages and loose parts removed.

If possible the surrounding areas of reinforcing shall be uncovered and rust is to be removed. Ripping strength of the surface layer may not be lower than 1.5 N/mm². The base may be prepared by shot blasting, milling or pressurised water jet, etc.  It is not permissible to allow poodles. The BAUBOND suspension is applied using a brush.
