Resurfacing Damaged Concrete
How to prepare the existing surface and mix, apply, and finish a concrete patch.
When resurfacing damaged concrete, begin by preparing the damaged area by removing all loose material and dirt. It’s a good idea to prime the old concrete first using a concrete bonder to ensure adhesion. Next, mix fast-setting concrete patch with water, following the manufacturer’s recommended ratio and making sure to scrape all the dry material from the bottom of your mixing bucket in the process. Mix only as much material as you can place in about 15 minutes. Trowel the patch flush with the surrounding concrete, then use a dry paintbrush to blend the old with the new. Depending on the temperature, the patch will be ready for traffic in an hour or two.
