Repairing Large Cracks in Concrete

Featured Product: Fast Setting Cement Patcher


PREPARATION

  • Clear out chipped, loose or unstable concrete from the repair area. This may require a hammer and chisel to break away the pieces.
  • It may be necessary to widen the crack in some places. Once the area has been prepared, sweep away all loose concrete debris.
  • To ensure the area is adequately prepared for the repair, use a pressure washer or water hose to clean the area of dirt and surface build up. This step will contribute to obtaining a good bond between the existing concrete and the repair material.


APPLICATION

  • Follow the mixing instructions and mix the dry powder to the water requirements to ensure the material mixes properly.
  • Using a margin trowel, thoroughly mix the material to a trowelable consistency and until all lumps have disappeared.
  • Using the margin trowel, place the material in the crack.
  • In thin sections, it may be necessary to turn the trowel sideways to work the material into the voids until filled.
  • Continue this process filling the crack and repair area.


FINISHING

  • It may become necessary to use a finishing trowel and apply pressure to fill some of the voids.
  • This step will aid in pushing the material into the voids and will also smooth the surface of the repair area.
  • Use the finishing trowel to put a neat edge on the side of the repair and remove any excess material from joint areas.
  • Use a brush to smooth and blend the patch material into the existing concrete surface.
  • A successful crack repair using Sakrete Fast Setting Cement Patcher.


Tip: When using Fast Setting Cement Patcher at 1/4 inch, Sakrete Bonder & Fortifier must be used.

Calculated results will reflect how many bags are needed for Block and Brick.

Enter the number of bricks (8" x 2" x 4") or blocks (8" x 8" x16") in the box below that you plan to use for your project. The calculator will then tell you the number of bags you need based on the different size of bags we carry.

This calculator is based on a 3/8" mortar joint. All yields are approximate and do not include an allowance for waste, uneven subgrade or any other variations from the joint size and brick and block sizes noted above.
