On the surface, it might seem strong. But you’ll never know if your concrete needs some resurfacing done. It might be hiding surface imperfections that will further harm you and your family in the future. Concrete gets worn out over time; it is a regular thing. Aesthetics isn’t everything; as a homeowner, it is your responsibility to check if everything is in good condition. Even if you have the most beautiful patio, concrete driveway, pool deck, or even indoor floors, check their surfaces since they are prone to damage.
Fortunately, there’s no need to repour the concrete if only mild damage or minor cracks on your driveway, sidewalk, or patio surface. It is not necessary to completely replace the concrete slab, as there are other repair options to fix the issue. And that is concrete resurfacing, but what is it? And how did it differ from the traditional procedure?
This blog will guide you through the process.
What is Concrete Resurfacing?
Concrete resurfacing does not necessarily mean you have the tear and remove the old concrete surface and replace it with a new one. That’s the traditional procedure; however, no one has to do all that and consume much time with concrete resurfacing. Resurfacing concrete will need the existing concrete structure as the base, and then the new resurfacing material is laid on top of it. As a result, it becomes a new surface.
Minor damages such as cracks, discolorations, imperfections beneath, updating finishes, or covering unsightly concrete would be solved with concrete resurfacing.
How to Resurface Concrete?
Here is a step-by-step guide on how to resurface the concrete. Remember to follow proper surface preparation procedures so that it will be installed properly.
Steps in Surface Preparation
An improperly prepared surface may cause further damages. So, before you begin to resurface, here:
- Clean the area. It is a must to clear out every surface dirt. Make sure to wash away or sweep away rocks, sand, leaves, and other materials off the surface. Some homeowners prefer washing the area with soap and water or other cleaning products. However, it is necessary to ensure that it is free from soap or chemicals.
- Remove the unsound concrete. You must remove all delamination, scaling, and minor spalling before proceeding to resurface. Concrete resurfacing materials can be affected by these extraneous materials.
- Fill up the cracks. Make sure to have a smooth surface before proceeding to the job. An actively growing gap can inhibit the adhesion of the resurfacer material, and if it isn’t filled, the new surface will develop cracks and breaks.
- Increase the surface’s grip. It is not ideal for the surface to look shiny, so you have to roughen it slightly.
After preparing, let’s get down to the real business.
This concrete resurfacing job requires expertise and training; therefore, it would be better to hire someone professional in doing this job. However, if you insist on doing it alone, just continue reading the steps.
To mix the resurfacer, you first need to get it in a dry powder form. Pour water into the correct proportions and mix well. As part of the resurfacer production, this step is essential, as it determines the quality and strength of the finished product.
Once done with the resurfaced, you can fill the walkway joints now. Make sure to seal it with peel-and-stick foam weatherstripping. You can mix half a bag of powder with 512 cups of water at a time since the resurfacer is workable for about 20 minutes. The amount will cover two sidewalk slabs or approximately 17 square feet. Pour it.
Trowel out the resurfacer, and make sure the thickness is between 1/8 inch to 1/4 inch. You can make the surface slip-resistant by sweeping it with a nylon-bristle concrete broom, 90 degrees away from the traffic. Lastly, remove the weatherstripping after 20 minutes. In the meantime, cover if rain appears imminent.
Please do not walk on it yet; it can be walkable after 6 hours.

Does Concrete Resurfacing Last?
It depends on the material you used, but if you hire professional concrete resurfacers to do the job and install it with a high-quality resurfacing product, it will last for ten years and more. However, you will not get the same longevity if you go with a DIY resurfacing kit from a big box store.
In addition, keeping your new surface clean, maintained, and protected will make it last for years to come. You will also need to reseal your concrete as required.
Call a professional
Doing the job by yourself appears to be the most cost-effective way. But is it? Problems could arise after a few months. There could still be hidden imperfections beneath the surface that you weren’t able to address. It could cause you more money, and it might worsen the scenario.
So, why not trust a trusted masonry contractor? Professionals guarantee quality since they have the expertise and knowledge to do the job. It would help to ask for an estimate so you can budget!
