Wire brush areas of the concrete surface that may be unstable to remove loose pieces. Sweep the concrete with a push broom.
Apply a heavy-duty degreaser to the concrete surface with a scrub brush over any areas that have oil spills or grease. Work the degreaser in with the brush in a circular motion. Rinse the surface with clear water from a garden hose. Allow the surface to air-dry.
Wear a dust mask and eye protection. Attach the metal mixing blade that came with the resurfacer kit to a three-eighth inch power drill. Add the liquid portion of the resurfacer to a clean and empty five gallon bucket.
Insert the mixing blades into the liquid in the bucket. Turn the drill on at a slow speed. Slowly add the dry portion of the resurfacer to the liquid mixture while continuing to combine the mixture with the power drill.
Switch the drill to a higher speed once the mixture has been combined. Continue mixing at high speed until the mixture has a smooth consistency without any chunks. Turn off the drill and remove the mixing blades. Allow the mixture to sit for a few minutes before using.
Insert the mixing blades into the mixture and turn on the drill. Mix the resurfacer a few more minutes just prior to application.
Apply a fine mist of water to the surface of the concrete to be resurfaced with a garden sprayer. Sweep any water that has puddled from the concrete with a squeegee or broom.
Dip an epoxy-safe three-eighth inch nap paint roller into the mixture contained in the five gallon bucket. Apply the mixture by rolling an even coat over a four by four foot section of the concrete. Continue applying the mixture in four foot square sections until the entire surface of the concrete has been covered.
Allow the resurfacer to dry for 24 hours before foot traffic and four days before vehicle traffic is allowed on the surface.
