Fortify and Beautify Your Concrete Floors

If you have concrete floors that have not been polished, then you are truly missing out. Polished concrete not only looks more beautiful than unpolished concrete, it is also much stronger and more durable. By adding a densifier such as lithium silicate and then polishing it down to a perfect sheen, the concrete has its cracks and holes filled, making it stronger and less likely to wear over time. Call Floor Skinz today to get a free estimate on polishing your concrete floors.

Advantages of Polished Concrete

  • Much stronger

  • More durable

  • Water-proof

  • Stain-proof

  • No more dusting

  • Aesthetically pleasing

Why Choose Polished Concrete?

Polished concrete is growing in popularity quickly. Densifier is used during the polishing process to fill in some of the pores and harden the concrete slab. The harder or denser the concrete, the less water can penetrate and stain the concrete. The most common densifier is lithium silicate. Densifier gets applied several times while polishing a floor. It is also often added to new concrete to harden the slab and help “seal” it to prevent the dusting. This dust that people see after new slabs cure is (calcium carbonate) the byproduct of calcium hydroxide rising to the surface and hitting the atmospheric carbon dioxide. Densifier will harden a slab during polishing & minimize dusting. If sealing the slab to stop water or oil penetration a more substantial sealer will be needed.

Concrete Polish Process - Step By Step

A polished concrete floor has a beautiful, glossy, mirror-like surface — but getting that beautiful finish takes a lot of experience and work! Here are the general steps in the process:

  1. Remove any existing floor coatings on the concrete surface. We do so with a special tool specifically for coating removal

  2. Seal cracks with epoxy or another appropriate filler

  3. Grinding the floor with successively finer grit diamond grinders

  4. Apply a chemical hardener, or densifier, to the concrete to seal it and prevent dusting

  5. Polish with increasingly finer grit resin-bond diamond.

  6. Finish with a 1500- or 3000-grit resin-bond diamond to achieve the desired level of shine

  7. Optional: apply a stain guard to make the surface even easier to maintain.


Polished concrete is a great no-wax flooring material that gives you a long-lasting gloss, similar to an epoxy flooring. It’s incredibly durable, and a great choice for retail, commercial, and office space. Some homeowners love the look so much that they apply it to concrete floors in their own homes! It’s a unique, smooth, high-luster flooring system that will last for years to come.

Can All Concrete Be Polished?

Nearly any structurally sound concrete floor can be polished, with the right concrete contractor and the proper preparation. For new floors, no special floor preparation is needed to produce stunning results. However, The flooring does need to be in place for around a month before polishing the concrete to ensure that the concrete is fully cured.

As for existing concrete floors, polishing can bring to life a boring, aging surface. However, more preparation needs to be done before beginning the concrete polishing processing. Any cracks or imperfections, such as grease or blemishes, can lead to imperfections in the finished floor. Floors that aren’t level, need extensive patching, or are extremely porous may not be the best candidate for concrete polishing. Our New Jersey flooring experts can determine whether or not your floor is suitable for concrete polishing. If you’d like to request a free estimate, contact Floor Skinz today.
