1. Surface Preparation: Ensure the repair area is clean, dry, and free of dirt, oil, dust, and loose concrete. Use a wire brush and industrial vacuum for thorough preparation.

2. Mixing: For small cracks: Combine 1 part A with 1 part B and mix thoroughly for 20 seconds.

For larger cracks: Mix 1 part A with 1 part B, then add 5-10 parts of sand and mix thoroughly. Example: Mix ½ pint each of Part A and Part B, then add ½ gallon of sand.

3. Application: For hairline and small cracks: Apply the mixed liquid directly into the crack and allow it to cure.

For larger patches: Apply the sand slurry with a trowel and smooth the surface to remove excess material.
