Resurfacing Damaged Concrete
Learn 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.

Impressive repair. The video says It was done in four batches, and the concrete sets up quickly, but the final result looks like a continuous pour. Was the repair allowed to dry after each batch was applied, or were the batches done one right after the other to essentially make a continuous pour?
They were done one right after another, so basically a continuous pour with one guy mixing and another placing and troweling. This stuff sets up fast.
I suspected that might be the case (since it looks so seamless) but wanted to be sure. Thanks.
This type of repair method would not last more than 1 or 2 years in areas where there is freeze/thaw. I work in concrete restoration - this patch would need mechanical securement in the form or rebar, mesh or combination thereof to hold in place.
When resurfacing damaged concrete, the method described here may not always be the most effective, especially for larger or more severely damaged areas. Instead, I recommend consulting with a professional concrete contractor who can assess the damage and use advanced techniques and materials to ensure a long-lasting repair.
