5 Tips To Resurface Old Concrete Floor In San Marcos

5 Tips To Resurface Old Concrete Floor In San MarcosConcrete floors, though long-lasting and durable, can wear out or become damaged over time. Instead of replacing the entire floor, which can be a costly and labor-intensive affair, resurfacing provides a practical alternative. Resurfacing rejuvenates the look of your old concrete floor while enhancing its functionality and lifespan. If you’re considering giving your concrete floor a facelift, here are five vital tips to help you get the job done.

  1. Before embarking on the resurfacing process, it’s crucial to ensure the old concrete surface is clean. Dirt, oil, grease, or any old paint need to be removed, as they can prevent the new material from bonding correctly. Pressure washing is a useful method to deep-clean the surface. Chemical cleaners, such as degreasers or etching solutions, can also be employed to get rid of stubborn stains or to help open up the pores of the old concrete, ensuring better adhesion.
  2. Once the floor is clean, inspect it for any cracks, spalls, or damages. Using a quality concrete patch or filler, repair these imperfections. Ensure that the patches are smooth and level with the rest of the floor. Resurfacing over uneven patches can lead to an unsightly finish, and the resurfaced layer may not last as long.
  3. Various concrete resurfacing products are available in the market, each designed for specific applications. Whether you’re looking for a simple overlay, decorative finishes, or a slip-resistant surface, select a product that best suits your needs. Pay attention to drying time, adhesion capabilities, and compatibility with your existing floor.
  4. Proper application ensures the longevity of the new surface. Follow the manufacturer’s instructions carefully. Typically, it’s recommended to dampen the old concrete before applying the resurfacer, as this prevents the substrate from drawing moisture out of the overlay. Using a squeegee, trowel, or a broom, spread the resurfacer evenly across the floor. Ensure there are no bubbles or inconsistencies.
  5. Once your floor is resurfaced, protect it from damage by sealing it. Concrete sealers prevent moisture penetration, resist stains, and can offer UV protection for exterior surfaces. Depending on the traffic and usage of the floor, reapply sealers as needed over time.


How Long Does A Resurfaced Concrete Floor Last?

With proper care and maintenance, a resurfaced concrete floor can last for over a decade. However, the longevity also depends on the quality of the resurfacing product used and the environmental conditions it’s exposed to.

Can All Concrete Floors Be Resurfaced?

While most concrete floors can be resurfaced, floors with extensive damage or those that are uneven might not be suitable candidates. It’s essential to assess the condition of the floor before proceeding with the resurfacing.

How Soon Can You Walk On A Resurfaced Concrete Floor?

Typically, you can walk on a resurfaced floor after 24 hours, but it’s always best to follow the manufacturer’s recommendations. For vehicular traffic or placing heavy furniture, it’s advisable to wait for at least 72 hours.


Resurfacing an old concrete floor is a cost-effective way to restore its aesthetics and strength. Following the proper steps, from cleaning to sealing, is pivotal to achieve a lasting and beautiful finish. With the right materials and a bit of diligence, your old concrete floor can look brand new and serve you for many more years.
