Koster Repair Mortar Plus is a watertight, fast setting, slightly expanding repair mortar with excellent adhesion even to old building material substrates. With the addition of Koster SB Bonding Emulsion or Koster Mortar Boost, it can be used as a PCC (polymer modified cement concrete) mortar.
The material is intended for the execution of watertight repairs and touch ups. It can be used for the installation of fillets in the wall / floor junction which are exposed to pressurised water prior to the application of bitumen thick film sealants (Koster Bikuthan 1C and 2C, Koster Deuxan Professional and 2C) and mineral coatings (Koster KD System, Koster NB etc.). The material can be used as a PCC Mortar, for under filling machine foundations as well as for filling blowholes, cracks, and oversized joints, for repairing breakages as well as a plugging mortar.
