How To Repair Salt-Damaged Concrete

Step 1

Sweep the damaged concrete with a stiff-bristle push broom, using vigorous motions to dislodge any remaining chips and crumbles from the concrete. Push this material into a dust pan and then into a trash can.

Step 2

Turn on a garden hose and spray the entire concrete area with a light spray of water until all of the concrete changes color but there are no water puddles on it.

Step 3

Fill a bucket with 1 to 2 cups of concrete, or more if you are repairing a very large area such as a driveway. Slowly add water to the mixture until it is the consistency of paint. Stir the solution well with a paint stirrer, and then use a paintbrush to apply a thin layer over the entire damaged area of concrete.

Step 4

Fill another bucket with a mixture of three parts gravel, two parts coarse sand and one and a half parts cement. Mix the solution with a trowel and add water until it is the consistency of peanut butter.

Step 5

Step 6

Scoop up 1/2 cup of the mixture on the trowel and place it in the damaged areas of the concrete. Smooth the top of it out with the back of the trowel until it blends in with the surrounding undamaged concrete.

Step 7

Place an old board on top of the concrete patch, and move it from side to side over the surface until the gravel sinks down and produces a smooth upper surface.
