How to Mix Concrete Resurfacing Mixture

Resurfacing concrete is the application of a thin layer to fill in and hide cracks without the need for repaving.

Concrete is a porous material when it is not sealed. Unsealed concrete can develop cracks or holes which hold water and further deteriorate the concrete in a walkway or driveway. Mixing concrete resurfacing material in a thick application fills in the cracks and holes, and levels the concrete project. You then mix the resurfacing mixture at its regular thickness to add a layer of resurfacing to the concrete.

Things You'll Need

• Concrete resurfacing powder
• Water
• 1-gallon bucket
• Trowel
• 5-gallon bucket
• Drill with mixing paddle
• Long-handled squeegee

Instructions

Surface Preparation

1. Add one part water to seven parts concrete resurfacing mixture in a 1-gallon bucket.

2. Mix the surface preparation thoroughly with a trowel until it is about the consistency of peanut butter or brick mortar.

3. Apply the resurfacing to deep cracks and holes with a trowel to level the concrete. Let the resurfacing mixture dry thoroughly.

Resurfacing Mixture

1. Pour 3.5 quarts into a 5-gallon bucket. Add one 40 lb bag of resurfacing mixture to the bucket.

2. Insert a paddle mixer into a drill chuck. Tighten the chuck and place the paddle in the bottom of the bucket.

3. Turn the drill on and move it up and down in the bucket. Touch the drill paddle to the sides of the bucket and move it in a circle to incorporate all of the liquid and powder together.

4. Mix the resurfacing for about five minutes.

5. Pour the mixture on the concrete and spread it out evenly with a long handle squeegee. One bag covers an area of about 12 square feet. Mix additional batches and apply to cover the entire concrete area.

Tips & Warnings

• Use concrete resurfacing when the temperature will remain above 80 degrees Fahrenheit for eight hours so it will cure.

• Do not apply the resurfacing material if it will rain within six hours. The added moisture will thin the material and it will run off the concrete. Hard rain drops can also make dents in your project.

• Apply a concrete sealer to keep your resurfacing job in place without the need to repeat the resurfacing project.

• The amounts of water and resurfacing powder may vary from one manufacturer to another. Consult the package instructions for your particular brand.
