How to repair old concrete areas?

Make sure to cut any damaged area of concrete in square form. Remove all the debris, dust and water. Reinforcing steel should be exposed and cleaned around its surface; clean and remove the corrosion of steel by alternative methods. Repair Mortar can be applied at the thickness of up to 50 mm thickness on old concrete areas.

Curing Method

  • When used with portland cement, the surfaces might need water curing for concrete strength.
  • Curing compounds may affect the adhesion of mortar with a substrate.
  • Curing of repair mortar commences immediately after finishing.

Precautions & Limitations

  • Repair mortar should not be used below 5°C & above 35°C.
  • Don't use partly used bags of repair mortar.
  • Part mixed repair mortar should be avoided.
  • Repair mortar should not be exposed to running water during the application or prior to a final set.
  • Water ponding is not recommended for curing.
