Substrate Preparation

  • Clean the surface thoroughly, removing dirt, oil, paint, and concrete fragments
  • In case that applying surface is in a spalling condition, old surface must be removed for a solid layer before repairing work

  • In case that plastering mixture become swollen, use wood trowel to stir or let the surface dry before further plastering
  • For chipped corner fixing, use 2 trowels to shape both sides to prevent mixture overflow to the other side
  • If the mixture tends to flow in vertical during the plastering, reduce the water ratio until it fits with repairing surface and temperature


Curing
The mixture normally absorbing water and cure itself naturally. In case of high temperature or strong wind at job site, Crocodile Admix Cure is recommended to preserve internal moisture

Usage ratio
Crocodile Repair Mortar 1 bag (20 kg) per 0.011 m3
