Prepare your tools and materials.
Next, check the weather condition: If the temperature isn't below 50 degrees, you tin can move forward with confidence.

Next, subsequently lightly dampening the driveway, prefill any cracks or holes with a small amount of the mixture. With that done, cascade the balance of the resurfacer onto the driveway and, with your long-handled duster, push and pull the material across the surface to create an even layer upwards to an eighth of an inch thick.
