Application
Consumption Estimated consumption of the preparation:
0.7 – 2.2 kg/m2 when executing a bonding coating
2.2 – 3.7 kg/m2 of reinforcement bar when applied twice,
Substrate preparation The concrete surface should be free of cement milk, dust, loose defects and impurities, such as, e.g., Lubricants, oils and other
The surface should be matted/roughened,
The average strength of the substrate should be min. 1,5 MPa, and the value of a single measurement cannot be less than 1,0 MPa,
The concrete surface should be matt and damp (uniformly dark, matt, devoid of bright and dark spots, and standing water).
Prior to the material application, the elements of reinforcing steel should be cleaned of rust to Sa 2 ½ degree of purity, using abrasive blasting (e.g. sand blasting), according to PN-EN ISO 8501-1.
Stirring ratio Add approx. 20 – 25% of water; i.e., approx. 5 – 6 liters per 25 kg of dry preparation.
Stirring Pour approx. 2/3 of water into a container, then pour the bag contents. Mix the contents using a contra-rotating stirrer (with a maximum rotational speed of 500 rpm) Add the remaining part of water and continue the mixing. The total mixing time should be approximately 4 – 6 minutes.

Types of application
Bonding coating The mixed mortar should be applied on matt and damp substrate with a brush – wide brush or by spraying. The size of the bonding coating surface should be so selected that the mortar can be applied on the unbound bonding coating ("wet on wet” application method). If the bonding coating dries before applying a repair mortar, remove and re-apply it.
