How To Get High Gloss Concrete Polishing And Finishing

High gloss concrete polishing has gained some popularity in the construction industry in recent years. From residential spaces to commercial complexes, more and more people are recognizing the benefits of achieving a high gloss finish on their concrete surfaces. 

The glossy sheen creates a visually striking effect that adds a touch of sophistication and elegance to any environment. It enhances the ambiance and creates a sense of luxury that can greatly enhance the overall appeal of a space.

However, the significance of high gloss concrete polishing goes beyond mere visual appeal; achieving a high gloss finish enables the concrete surface to become highly resistant to wear, stains, and damage caused by heavy foot traffic or other environmental factors. 

This article looks at what concrete polishing is, the polished concrete floor process, and what makes concrete glossy. 

What Is Concrete Polishing?

Concrete polishing is a specialized process that involves refining the surface of concrete to achieve a smooth, glossy finish. It is typically performed using diamond abrasives and chemical densifiers that work together to transform ordinary concrete into a visually appealing and highly durable surface.

To enhance the glossy finish and protect the polished concrete, a high gloss concrete sealer is often applied. The sealer forms a protective layer that intensifies the shine and luster of the polished surface. It provides additional durability and resistance to stains, chemicals, and wear, especially in high-traffic areas.

In residential spaces, polished concrete floors can create a modern and stylish look. In commercial settings like retail stores, hotels, and restaurants, polished concrete is valued for its durability and aesthetic appeal. It is also commonly used in industrial facilities due to its resistance to heavy machinery, chemicals, and high traffic.

Concrete polishing has become a popular choice for those seeking a cost-effective, long-lasting, versatile, and visually appealing flooring option. Its ability to enhance appearance, increase durability, and simplify maintenance makes it a versatile solution for a wide range of projects.

How to Achieve High Gloss Concrete Polishing and Finishing on Concrete

To get a high gloss finish on concrete, you should follow these key steps:

Step 1: Surface Preparation

Here, you are to clean the concrete surface to eliminate any coatings, adhesives, or impurities that may be present. Surface preparation ensures a clean canvas for the polishing process and allows for better adhesion of subsequent treatments.

Step 2: Grinding and Leveling

Grinding and leveling are done using a concrete polishing machine, which utilizes rotating diamond abrasives to remove imperfections and create a smooth and even surface. The machine’s diamond tools effectively grind away any roughness, unevenness, or minor flaws present in the concrete. 

If you know how to polish concrete by hand, you can opt to grind with hand-held diamond pads or abrasive blocks. While manual grinding and leveling may be more labor-intensive, it allows for greater precision and control in smaller or hard-to-reach areas.

Step 3: Polishing Process

After the surface has been properly prepared, the polishing process begins. For achieving a high gloss finish, a series of diamond abrasives with progressively finer grits are used. 

Starting with a coarse grit, the diamond abrasives are systematically applied to the concrete surface using the concrete polishing machine or by hand.

As the polishing progresses, finer grits of diamond abrasives are used, gradually refining the surface and enhancing its smoothness. The process involves multiple passes with each grit, ensuring that the desired level of gloss is achieved.

Step 4: Densifiers and Sealers

To enhance the gloss and protect the polished concrete, densifiers, and sealers are applied to the surface. Densifiers are chemical solutions that penetrate the concrete, reacting with it to create a hardened and densified surface. This process strengthens the concrete, increases its durability, and contributes to its glossy appearance.

Once the densifier has cured, a high-gloss concrete sealer is applied. The sealer forms a protective layer on the surface, intensifying the shine and providing additional resistance to stains, chemicals, and wear. The sealer acts as a barrier, enhancing the longevity of the high gloss finish and simplifying maintenance.

What Makes Concrete Glossy?

The glossy appearance of polished concrete is achieved through a combination of factors that work together to enhance the surface reflectivity and shine. These factors include: 

1. Diamond Abrasives

Diamond abrasives are important in the concrete polishing process. They consist of industrial-grade diamonds embedded in resin or metal bonds. 

As these diamond abrasives are applied to the concrete surface, they grind away imperfections and create a smooth and refined finish. The progressively finer grits of diamond abrasives used in the polishing process help to achieve a higher level of shine and gloss by further smoothing the surface.

2. Densifiers

Densifiers are chemical solutions that are applied to the polished concrete surface. They penetrate the concrete and react with its minerals, typically calcium hydroxide, to form a hardened and densified surface. This chemical reaction creates a stronger and more durable surface that enhances reflectivity and glossiness. 

Densifiers also contribute to the overall appearance of the polished concrete by increasing its clarity and depth.

3. Polishing Technique

The technique used during the polishing process is crucial in achieving a glossy finish. Properly trained professionals understand the optimal speed, pressure, and movement required to achieve the desired results. 

The polishing technique ensures that the diamond abrasives effectively smooth out the surface and bring out its maximum shine. Skillful and consistent polishing techniques contribute to the overall glossy appearance of the concrete.

4. Maintenance

Proper maintenance is essential for maintaining the glossy look of polished concrete over time. Regular cleaning and maintenance routines, such as sweeping and occasional damp mopping, help to remove dust, dirt, and debris that can dull the surface. 

Avoiding harsh chemicals and using pH-neutral cleaners specifically designed for polished concrete can help preserve its shine. Also, periodic reapplication of a high gloss concrete sealer can help protect the surface and maintain its glossy appearance.

What Not To Use On Polished Concrete?

To maintain the appearance of polished concrete, certain substances and cleaning methods should be avoided. Here are some things you should not use on polished concrete:

  • Avoid using acidic cleaners, such as vinegar or citrus-based cleaners, as they can etch or damage the polished surface. Similarly, abrasive cleaners or scrubbing pads can scratch the surface and dull the shine. It’s best to use pH-neutral cleaners specifically designed for polished concrete.
  • Stay away from bleach, ammonia, and solvents. These harsh chemicals can cause discoloration, staining, or degradation of the concrete surface. 
  • Avoid using steel wool or wire brushes for cleaning polished concrete because they can leave scratches and marks on the surface. Instead, use soft bristle brushes or microfiber mops for gentle cleaning.
  • High-pressure water or steam cleaners; can force water deep into the concrete and potentially cause issues with moisture or efflorescence. Stick to regular mopping or low-pressure water spray for routine cleaning.
  • Do not apply oil-based or wax-based sealers on polished concrete. These types of sealers can create a greasy or slippery surface, compromise the natural shine, and potentially require more frequent maintenance.
  • Avoid dragging heavy furniture or sharp objects directly on the polished concrete surface. Use furniture pads or protective mats under heavy items to prevent scratches or indentation.

In all, always follow the manufacturer’s recommendations and consult with professionals for specific care instructions based on the type of polished concrete and the sealants used in your particular installation.
