Proper use of hydraulic cement for maximum benefit include the following steps:



  • The surface on which the cement is to be applied should be clean. Dirt, oil, grease and loose particles will prevent the cement from adhering to the surface properly.
  • It is imperative for the temperature to be maintained between 45°F (7°C) and 90°F (32°C) during initial curing since the cement will not be durable on frozen surfaces.
  • The area should be saturated for 24 hours before applying cement there.
  • Small cracks and holes should be enlarged prior to the cement application. V-shaped cuts are to be avoided.

Mixing Cement

  • A mechanical mixer with rotatory blades is recommended for mixing the cement to get a uniform mix.
  • The mixer should be saturated and drained of excess water prior to mixing.
  • Following the manufacturer’s instruction, the required amount of water is to be added to the proper amount of dry hydraulic cement. However, once it begins to set, water should not be added anymore.
  • It is recommended that small amounts of cement be mixed at a time since it hardens very quickly and has to be placed within 10-15 minutes.
  • The cement mix should be blended at a relatively low speed.

Applying Hydraulic Cement

  • The hydraulic cement mix should be applied as quickly as possible.
  • Excessive blending will cause bleeding and segregation.
  • Any other additives or admixtures should not be added unless mentioned in the manufacturer’s instructions.
