How to Resurface Concrete

Updated: May 23, 2023

Concrete, while one of the strongest materials, is susceptible to fracturing over time. The unyielding material is likely to develop cracks, discoloration, or signs of senescence. The primary culprits of concrete's deterioration include heavy foot-traffic, intense pressure, exposure to chemicals or weather conditions, and other deleterious factors. How can one avert the disrepair of their concrete surfaces? Replacing the concrete is one alternative; however, this option is neither obligatory nor fiscally responsible. Another more budget-friendly and efficient solution is resurfacing your concrete floors, particularly if they have weathered poorly.

Steps to a well-resurfaced floor

Cleaning the surface

Prior to initiating any installation or techniques, it is crucial to clean the surface thoroughly. Any extraneous materials, such as dirt, oils, stains, and the like, must be purged. This preparatory step can be accomplished by utilizing a pressure washer or mechanically cleansing the surface, depending on the indoor or outdoor location

Fix it good

Before embarking on the resurfacing of your concrete, it is imperative to address any underlying issues, such as cracks, spalling, stains, and other concrete-related maladies. It is advised to consult with a professional to determine the optimal materials for repairing any cracks or spalling. Investing in high-quality materials will ensure the longevity and aesthetic appeal of your concrete surfaces.

Remove the past

It is essential to remove any previous coatings, such as paints, sealants, waxes, or other surface treatments, before commencing with the resurfacing process. Failure to do so will impede the effectiveness of the resurfacing. This is accomplished by mechanically grinding down the surface and stripping off any remnants of prior coatings, thereby opening up the concrete's pores.

Hose it

If feasible, it is recommended to hose down the area after the surface has been repaired. Following the repair, the surface must be thoroughly cleaned once again. If hosing down is possible, the standing water should be eliminated from the surface.

Blending time

To mix the resurfacer, a 5-gallon bucket is typically used. This can be done either by hand or with a power drill. It is crucial to follow the instructions carefully and use only the recommended amount of water-to-resurfacer ratio. Failing to prepare a proper mixture will result in a weak and short-lived surface.

Weather or not

Before you commence resurfacing your floors, it is crucial to be aware of the weather conditions. If you're working solo, it's recommended that you divide your work into smaller sections, instead of attempting to resurface the entire surface all at once. Pour the mixture in broad strips, and quickly squeegee it across the surface before it dries. This will ensure a smooth and uniform surface.

Texturizing it

After applying the resurfacer, wait for a few minutes until it becomes semi-dry. Then, use a broom to create a safe non-slip surface by running it consistently across the entire floor. Make sure to do this repeatedly to ensure uniformity.

Finishing up

It is important to maintain a clean and dry area for at least 24 hours after applying the resurfacer to allow it to cure properly. In extremely hot weather, make sure to spray the surface with water to prevent it from drying too quickly, which could cause cracking.

Seal the deal

After two hours of drying, the resurfaced concrete can be lightly used. However, it's recommended to wait for 24 hours before applying a sealer to enhance the durability and aesthetic appeal of the surface.
