A Beginner’s Guide to Concrete Polishing

Ongoing concrete polishing work

Concrete polishing transforms your concrete floor into a stylish structure with a durable yet glossy finish. There is a wide variety of designs and colors you can choose from for a fulfilling concrete structure. And the fact that it is easy to maintain is the icing on the cake. That is the reason why it is commonly used in many commercial and residential premises.

The Concrete Polishing Procedure

The concrete polishing process involves the use of diamond particles fused in a metallic disk. The coarse particles eliminate small holes, unwanted marks, and coatings from the concrete surface you want to polish to make it smooth. The grinding happens from the biggest grit to the smallest until you achieve the desired results.

The same way you would sand wood, you use coarser-grits then finer grits of polishing disks to give the concrete floor the right glow. A highly-experienced concrete polishing expert understands when to change to the next polishing grit as the process moves from one level to another.

The process ends by applying a hardener, which impregnates a chemical solution into the concrete to bonds with it. Doing this protects the concrete and does away with the need for coating. You could also apply a concrete floor polishing solution after grinding to improve your floor’s gloss and eliminate any filtrate that might remain on the floor after polishing.

There are two methods used in the concrete polishing process. These are the dry and wet methods. Each has its benefits and drawbacks. But most concrete polishing experts prefer the dry approach to the wet because it is much faster and eco-friendly. It doesn’t require water use and has a mechanism that controls dust during the concrete grinding process.

Steps to Follow During Concrete Polishing

  • Survey the Concrete Before Polishing

It is important to check the condition of the surface that needs polishing. Bear in mind that not all concrete surfaces can be polished. Newly installed concrete requires some time to cure and dry adequately before you carry out the process. Also, severely damaged or very soft concrete structures cannot be polished until you patch them up. In this case, look for cracks, stains, paints, coatings, sealers, and adhesives on the floor and repair or remove them.

  • Surface Preparation

Remove all the sealers and coatings from the floor. If there are badly spalled areas and major cracks, you should consider an extensive overlay. Otherwise, fill any minor cracks with concrete filler and even it out so it levels the rest of the concrete.

  • Polish the Floor

Once the surface is even, start course-grinding it. You can divide the floor into sections and grind from one section to another while ensuring evenness. To make a little easier, let the sections run from one end of the floor to another. Besides, there are different diamond segments bonded in a metallic medium to use at this stage. For instance, there are 40, 80, 150, and 300-grit metal bonded abrasives, with the bigger number representing finer grinding.  

Be sure to start with the right bonded abrasive. You can begin with either 40grit or 80-grit depending on the condition of the surface. If the floor is too rough, then begin with 40-grit.

  • Concrete Hardening

Surface grinding is now over. Next, you should harden it. We usually use a liquid chemical hardener, which penetrates the concrete to solidify and make it water-resistant. You can use a broom with stiff bristles to spread the hardener on the surface.

Let the hardener penetrate through the concrete for about 30 to 45 minutes. Any excess hardener remaining on the surface after that should be removed. Also, concrete hardeners need curing. Check on the instructions on the container for the duration your hardener requires to cure. On average, it is between 12 to 24 hours.

  • Ultimate Polishing

Give your concrete a more elegant final finish. Start with a 100-grit resin bond. Move to 200, 400, onwards until you get the sheen you desire. The finest grit is 3000 and is meant for an exceedingly high-gloss finish. Take note that the first polishing requires a metal-bonded diamond while the final polishing requires a resin-bonded diamond.

  • Protection against Chemicals, Oil, and Other Spills

Your floor has a glossy finish that satisfies your desire. It now needs protection. Therefore, apply a stain-guard for polished floors. It increases the ability of polished concrete to resist different stains. You can apply it after every three months for effective maintenance.

The Requirements for Concrete Polishing.

Here are the tools and materials you need for the polishing process:

  • Concrete filler. The epoxy filler is ok.
  • Chemical hardener
  • Diamond-bonded abrasives
  • A dust vacuum device to contain dust during surface grinding
  • A floor polisher

What are the Benefits of Concrete Polishing?

Installing a polished concrete floor has the following benefits:

  • Polished concrete is easy to maintain. Regular mopping to remove dust and stains is the easiest method of cleaning the concrete.
  • Polished floors can handle heavy foot traffic without getting stressed.
  • It eliminates the need for coating concrete and the expense of reapplying the coats periodically.
  • Concrete polishing gives your floor the level of elegance that matches marble floors, which are highly-priced.
  • It is possible to achieve gleaming beauty by adding coloring products such as dyes and chemical stains.
  • Polished concrete is resistant to rust, dust, and spills. The damage occasioned by water is also reduced because the abrasives and the chemical hardener make the concrete waterproof.
