Generally, concrete resurfacing entails adding a new layer of concrete on top of old concrete. The process is performed using overlays comprising of cement or modified polymer systems.

Overlays comprising of modified polymer cement, sand, polymer resins, and other necessary additives are applied to enhance the performance, aesthetics, and wear resistance of concrete.

The products and process involved in resurfacing concrete vary depending on the kind of surface being repaired. For instance, an overcrete resurfacing system is applied thinly to decorate the surface while other systems like floor levelers are applied to a thickness of 30mm at most in a single application.

In case the surface needs filling the pre-existing patterns or holes, then it’s necessary to apply floor levelers before coating the surface with an overcrete resurfacing system.


Options Available

You can choose from a wide variety of textures, designs, and colors. If you want to change the look of the existing surface, you’ll have limitless options. You can choose between finishes such as sandstones, pavers, brick, and granite among others. You can also choose a color that will create an aged, stamped, or warm look depending on your preferences.


Restrictions for Resurfacing Concrete

You’ll need to ground off any pre-existing coating before resurfacing the floor since the coating may prevent the new surface from sticking in place.

Although small cracks may be sealed during resurfacing, large cracks should be fixed before resurfacing. Small and medium cracks can be repaired with a silica and epoxy sand mix. However, repairing cracks doesn’t offer guaranteed results. In case the old concrete re-cracks, you’ll eventually have to resurface it.

Also, any structural damages that might have occurred on the concrete floor, such as movements in the underlying soil, may not be fixed by resurfacing.

Also, ensure the foundation is sound enough to apply a concrete surface on top of the old concrete. If the old concrete is weak, flaky, chalky, or dusty, the new coating can easily lift off.

In case the old floor has such issues, it’ll require additional preparation before resurfacing it. Also, ground off the old layer of cement to create a solid concrete foundation for resurfacing.


How Much Does It Cost To Resurface Concrete?

The cost of doing a concrete resurfacing project will be determined by whether you’ll do the work yourself or hire a professional concreting company. In case you’re planning to do the work yourself, ensure you have the required skills, else you might end up losing a lot of money and time.

The cost will also be influenced by other factors such as the resurfacing product you’re using and the size of the space that you want to resurface.

Another factor that influences the cost is the required detailing. For instance, you’ll spend more money if you want a border color that differs from the body color. On the contrary, you’ll spend less if you’re using the same spray color on the entire floor.

Also, it’ll cost more if the project requires extra leveling before resurfacing. On a similar note, well finished and smooth surfaces are cost-effective and easier to resurface.

Generally, concrete resurfacing is an affordable way of bringing life to old concrete flooring without getting rid of the old concrete. You can choose to resurface the concrete yourself or hire a professional for more guaranteed results.
