Sealing resurfaced concrete is not an absolute necessity. However, it is recommended, and in most cases, a high-quality concrete sealer can protect the surface from stains as well as water penetration, extending the life of the resurfacing material. Some sealers are formulated to protect pigments from fading due to UV exposure. Sealer tends to enhance the colors in decorative resurfacing applications, making them more vibrant and richer compared to the duller, more faded appearance of concrete colors without sealer.

While you don’t technically need to grind concrete before resurfacing, it is very helpful. Grinding creates a rough, porous surface on the concrete, which gives the resurfacing material something to latch onto. Grinding your concrete before resurfacing can ensure that your resurfacing material lasts longer, reducing additional concrete resurfacing costs down the line.

You can pour concrete over existing concrete and then stamp it to create an overlay. The old concrete must be prepared correctly for the new concrete to adhere properly and create a strong, stable surface. Stamping the new concrete creates a patterned finish that adds visual interest and an upscale feel.

Water that pools on concrete indicates a low spot somewhere on your driveway. You can level the slab with a concrete patching compound to help redirect water. You can also install drainage over existing concrete by digging out enough space for a channel drain or French drain or by adding a culvert below the slab.
