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.

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.

Yes, you can pour new concrete over old concrete, but you need to apply a concrete bonding agent to the existing concrete to ensure the new concrete sticks. Keep in mind that even with a bonding agent, large cracks and other flaws will still come through. If the concrete has heaved, settled, or cracked, pouring new concrete on top won’t address any root structural problems. Removing the existing concrete and rebuilding will be your best solution in that case.

For handy homeowners, concrete projects are DIYable, and DIYing is a good way to save on the cost of a concrete slab, walkway, or other concrete work. If you’re completing a larger project or one that’s subject to building codes, you should always hire a professional to ensure the job is done safely and correctly.
