Concrete Patch & Crack Repair - Trowelable

Concrete Patch & Crack Repair - Trowelable

Cement based repair materials are used in major and minor concrete crack filling applications. Some of these repair materials are modified with polymers that enhance bonding properties and some are designed for fast setting. Before a repair material is chosen, evaluate the area and determine:

  • Width, depth and length.
  • Is it a vertical or horizontal repair?
  • Will the area need to be widened to properly repair?
  • Is this a moving crack? Does it appear to get larger over time?
  • Does the area get a lot of vehicle traffic?


The evaluation and diagnosis of concrete cracks may lead to many different options of repair materials. Sakrete offers multiple options for cement based crack repair materials. (See caulk tube and bottle - crack repair products)

Fast Setting Cement Patcher – High strength, rapid-setting material used for filling cracks in concrete slabs, driveways, sidewalks, steps and curbs. Use from ¼” – 2” in thickness.

Flo-Coat Concrete Resurfacer – Polymer modified concrete resurfacing material that can be applied in a flowable consistency using a squeegee when resurfacing but also in a stiffer consistency for trowelable crack repair material. Maximum depth of ½”.

Sand Mix Topping and Bedding Mix – High strength material used as a bedding and concrete topping material. Sand Mix can also be used as crack repair for areas with a minimum depth or width of 1/2” and maximum of 2”.

Top'n Bond Concrete Patcher – A polymer modified sand/cement repair material used in repairing cracks, leveling uneven concrete surfaces and as a concrete overlay. The range of repair is for a maximum of 1/2” down to feather edge.


Tips for using trowelable concrete repair material:
Preparation is key to any project

  • Remove all loose and unstable concrete from the repair area.
  • Clean area free from dirt, dust and contaminants that could interfere with bonding.
  • Eliminate grease, oil, paint, sealer or any other foreign materials that will inhibit bond.
  • Store bags in a shady area 24 hr before use. Heat and rays from the sun will make the bag contents hot which can cause flash setting.
  • Use cold water to mix material in high heat weather to help avoid flash setting.
  • Follow material instructions for preparation, use and placement.
