Crack and Spall Repair

Using Bulk Roadware 10 Minute Concrete Mender™

Applies to Concrete Mender™ and Concrete Mender™ Low Odor.

Use Roadware 10 Minute Concrete Mender™ in bulk for repairs of spalls and cracks that are wider than 3/4″. Before application, clean the cracks and spalls down to solid white concrete, and remove all dust and debris.

Pour 4 oz of Side A into a measuring container.

Pour 4 oz of Side B into a measuring container.

Roadware 10 Minute Concrete Mender™ must always be mixed in a one-to-one volume ratio.

Combine Side A and Side B into a larger container and mix by hand for about 10 seconds. You will now have 8 ounces of mixed Concrete Mender.

Promptly add up 16 – 20 ounces of silica sand and mix with a trowel. Click here to learn more about using sand with Concrete Mender.

Combine the sand and material thoroughly by mixing for approximately 10 seconds until they are well blended.

A reliable way to assess the sand-to-liquid ratio is to tap the side of the pail. If the mixture appears wet on top, your mix is just right.

Quickly place the material into the repair area. If the concrete is clean and in good condition, you do not need to prime it with pure material.

Trowel back some material and ensure that the Concrete Mender is thoroughly saturating the surface of the concrete. If the surface is not solid or if the concrete quality is poor, you may need to “prime” the surface using pure mixed liquid Concrete Mender™.

Smooth out the material as needed, but be careful not to overwork the mixture.

After 10 to 15 minutes at 70 degrees Fahrenheit, blend the repair into the surrounding concrete using a finishing brick, grinder, or polisher.

Use extra silica sand as a grit to give you a smooth finish.

Repair is now ready for coating, polishing, or heavy traffic.

Workers may be exposed to dangerous levels of silica dust when cutting, drilling, grinding, or otherwise disturbing materials that contain silica. These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses.  Click here to learn how to work safely with silica.
