Get matched with top concrete resurfacing pros in Springer, NM

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Mix the resurfacer into a sticky mixture. The consistency should look like mashed potatoes. Use a squeegee to push the resurfacer across the pitted area and smoothen the surface with a cement trowel flush. Make sure you protect any expansion joints with a weather strip. Alternatively, cut out any resurfacer that touched the joint once the mixture begins to harden.

DIY repair is possible for minor cracks or small areas, often through patching. For a durable, properly leveled, and seamless finish, professional repair or resurfacing is recommended.

Whether resurfacing concrete is worth the cost depends on the condition of the underlying slab. Resurfacing can be a good option if the concrete is in decent condition with only minor issues like standard wear and tear, small cracks, chips, or discoloration. In these cases, resurfacing adds a protective layer that can extend the concrete's lifespan without the high cost of a full replacement.

However, if the concrete has significant damage—such as deep cracks, peeling, sinking, or is broken up—resurfacing may not be worth it. The new overlay is only as good as the concrete beneath it, and existing problems like peeling and cracks are likely to show through the new surface. In situations with severe damage, replacing the entire slab is often more cost-effective in the long run and will yield a better result.

To make the best decision, it's recommended to have a licensed concrete specialist inspect the damage and determine if resurfacing is the right choice for your situation.
