Zebra installation manual


  1. Remove all delaminated and damaged concrete. After chiseling the concrete should emerge as solid and free from impurities. There is no need to remove all visible rust from the reinforcement bars, remove what is loose. 
  2. Connect reinforcement bars to continuity and verify before closing and leveling to surface.  
  3. Test adhesion on old concrete, the requirement is 1.2 MPa or break in the substrate. 
  4. Always use current open mortar for repairs where applying ICCP - Impressed Current Cathodic Protection. Preferably use a mortar with similar characteristics and resistance to prevent current drainage. 
All reinforcement bars must be in electrical continuity. No continuity - No ICCP! 

Test area  

To ensure that the Zebra system is reacting good with the concrete in the area to be treated a test must be carried out prior to big surface application. An area of about 1x1 meter is to be made with Zebra anode. When cured - apply Ahead primer to the center part of the field (let the edges be untreated so that the field can be connected to all later). Let cure and apply Ahead Leveling layer to half of it.  Take pull off tests between each step of the Zebra system to verify its consistency with the concrete and satisfying adhesion. 

Installation of the Anode layer 

Pay attention to temperature and humidity. The Zebra anode needs a min. temperature of  10°C on concrete surface. Do not apply if max. temperature exceeds 30°C on concrete surface. The anode should not under any circumstances be exposed to water before fully cured. 

Zebra PDR (primary anode)

PDR - Power Distribution Ribbon is a metal wire (Ti/Cu/Pl) that when installed correctly will work as an anode that will not corrode. It is essential that the PDR is in contact with the Zebra. 
  1. Start with looking at the design drawings for the project. Make clear where Zones meets and ends, and where the feeding cables and minus -reinforcement bar connections are. 
  2. All cross sections for PDR, and connection to cables must have connection pits. On floors the PDR needs chasings , cut them in straight lines.   
  • Chasings should be made 8 mm wide, and 2 mm deep. Maximum distance is 1.7 meters in between. 
  • For connection pits drill Ø 30 mm, and 20 mm deep. 
  • Vacuum-clean the thoroughly. 
  • Mix Zebra Anode paint and apply it with a 10 cm roller over the chasings. This is to achieve protection under the tape. Do not apply in the connection pits! 
  • Let dry and cure. 
  • Add PDR tape and after PDR in the chasings. 
  • Connect the PDR wires together in the connection pits using the special PDR Connector clips. 
Zebra Anode conductive paint (secondary anode)
When ZEBRA anode paint is applied the concrete temperature must be above 10o + with low humidity. If needed, use a dehumidifier.

Mix the ZEBRA anode conductive paint and apply in stripes using a 25 cm wide roller. Paint in between the chasings leaving a 5 cm gap between each 25 cm stripe. This ensures the currents is spread evenly to the surface. 

AHEAD Binder E/N (to protect PDR) 
AHEAD Binder E/N is used to insulate the PDR tape. Apply 0,1 kg/m2 over the Zebra PDR  with a 10 cm wide roller. Sand stew and leave to cure. 
Binder seals of the Zebra Anode and prepare it for alkaline protection layer to follow. 

Protective alkaline layer
Apply AHEAD Multiprimer Floor over the entire floor (normal consumption: 0,2 l /m2)
Apply one layer of AHEAD Levelling Layer over the entire floor (normal consumption 3,5 kg/m2).

The following day, continue with applying second layer of AHEAD Multiprimer Floor (normal consumption: 0,2 kg/m2). Let dry.
Then, apply second layer of AHEAD Levelling Layer over the entire floor (normal consumption 3,5 kg/m2).
