Full Answer

  1. Clean the existing surface

    Use a 3,500 pounds-per-square-inch pressure washer to clean the concrete, removing any dirt, grease, oil and deteriorating concrete. If there are deeply spalled areas, fill them with the appropriate concrete filler. Wet the surface and remove any standing water before applying the resurfacer.

  2. Mix the product

    Follow the manufacturer's mixing directions for the products. Some require mixing in a five-gallon bucket with a drill and paddle mixer and are not for hand mixing or use in a concrete mixer. The mix should be thin, easy to pour and free of lumps.

  3. Apply the product

    Apply the resurfacer in strips about 1 foot in width. Use a long-handled squeegee to scrub the material into the existing surface and then spread it smooth. For a non-slip surface use a concrete broom to add texture to the surface.

  4. Allow the concrete to cure

    The product cures for foot traffic within six hours and vehicular traffic in 24. Keep it moist while it cures, misting with water if temperatures are above 90 degrees Fahrenheit. Protect the product from freezing for the first 24 hours after application.
