BASF - MasterEmaco P 5000 AP

BASF plc, Construction Chemicals

MasterEmaco P 5000 AP active primer, not only reinstates a high pH environment it also contains active corrosion inhibiting additives for the protection of reinforcement steel. It can also be used as an adhesive bonding slurry for subsequent repair mortars.

It is a ready to use material that contains Portland cement, well graded fine fillers, re-dispersible powder and special additives.

When mixed with water, it forms slurry that can be applied by brush to the clean exposed reinforcement, or directly on the dampened, prepared concrete substrate when used as a bonding coat.

Features and benefits:

  • Meets all major national and international standards for steel priming in concrete repair systems.
  • Excellent rust inhibiting properties as it reinstates a high pH environment.
  • Contains active corrosion inhibitors to further protect the steel.
  • Polymer modified for additional adhesive bond to the steel.
  • Does not affect the pull out strength of reinforcement steel.
  • Compatibility with steel reinforcing bars and concrete or repair mortars.
  • Low chromate (Cr[VI] < 2 ppm).
  • CE marked.


MasterEmaco P 5000 AP is used for the protection of reinforcement steel:

  • When steel is visible and the available depth of cover is less than 10 mm.
  • When concrete is contaminated with chlorides.
  • In critical environments when extra protection is specified.
  • With MasterEmaco N 5200 repairs when steel is visible.
  • When the timing at the jobsite does not allow for the repair mortars to be applied immediately after cleaning the steel.

It can also be used to aid bonding and application properties of hand applied repair mortars in extreme thicknesses and conditions.
