How to Make Concrete Smooth and Shiny Like a Glass

smooth concrete finish

To attain a smooth concrete finish on concrete, careful preparation is paramount. Whether dealing with a new surface or refinishing an existing one, a step-by-step approach ensures success. So, if you are wondering how to make concrete floors shine?

The process begins by thoroughly cleaning the concrete, eliminating debris, and repairing cracks or imperfections. Utilize a concrete grinder with coarse diamond pads to initiate the grinding process, gradually progressing to finer grits for honing and Austin concrete polishing.

Selecting the right diamond pads is crucial, with each stage refining the surface towards a glossy sheen. Applying a concrete densifier enhances durability while sealing protects and amplifies the shine. Buffing and optional burnishing contribute to the final luster.

Regular maintenance, including cleaning and periodic resealing, preserves the glass-like appearance. Quality tools, patience, and attention to detail are key throughout the process, ensuring that your concrete surface radiates a smooth, reflective finish reminiscent of polished glass.

Surface Preparation

To achieve a glass-like finish on concrete, carefully prepare the surface with grinding, polishing, and precise sealing techniques.

Clean the Concrete

Before beginning the polishing process, ensure that the concrete surface is free from any dirt, dust, or debris. Sweep the area thoroughly and consider pressure washing for stubborn stains or contaminants. Allow the surface to dry completely.

Repair Cracks and Imperfections

Inspect the concrete for any cracks, holes, or imperfections. Fill these with an appropriate patching compound or epoxy filler, smoothing concrete floor.

Grind the Surface

Use a concrete grinder equipped with diamond abrasive pads to grind the surface. Begin with a coarse-grit pad to remove any existing coatings or rough spots. Gradually progress to finer grits until you achieve the desired smoothness.

Grinding and Polishing Process

To create a glass-like finish on concrete, employ a thorough grinding and polishing process, ensuring thorough attention to detail throughout.

Selecting the Right Diamond Pads

Choose the appropriate diamond polishing pads for your grinder. The pads’ grit levels typically range from coarse (30-50 grit) for initial grinding to fine (800-3000 grit) for polishing.

Initial Grinding

Start with the coarsest diamond pad to grind the surface thoroughly. Move the grinder back and forth, overlapping each pass to ensure even grinding. Continue using increasingly finer grits until the concrete smooth.

Honing the Surface

Transitioning to honing, employ higher grit diamond pads (typically around 200-400 grit) to refine the concrete surface carefully. This essential step goes beyond the initial grinding, ensuring the removal of any visible scratches and imperfections best concrete mix for smooth finish.

Polishing Steps

Continue polishing with increasingly finer diamond pads, progressing from 800 grit to 3000 grit or higher. Each step brings the concrete closer to a smooth concrete finish, eliminating finer imperfections and enhancing shine.

Densifying and Sealing

To achieve a glass-like sheen on concrete, apply densifiers to harden the surface and sealers to enhance shine and durability.

Apply Concrete Densifier

The application of a concrete densifier is essential to bolster the concrete’s hardness and durability. This chemical treatment reacts with the concrete, penetrating and filling pores, fortifying the surface and rendering it more resistant to wear and tear over time.

Wait for Curing

Allow the applied densifier to cure per the manufacturer’s guidelines. Typically, this entails maintaining a moist surface to facilitate the chemical reaction. Providing the necessary curing time is crucial, as it allows the densifier to effectively strengthen the concrete, enhancing its hardness and durability for long-lasting performance.

Sealing the Surface

Use a premium concrete sealer to improve the overall sheen and shield the polished surface from water stains. Select a sealant made especially for polished concrete.

Buffing and Burnishing

The buff and burned concrete is essential to achieve a smooth, glass-like finish, ensuring the surface reflects light with exceptional shine and clarity.


Following the sealing process, enhance the concrete’s final shine by employing a high-speed buffing machine fitted with a fine-grit polishing pad. This crucial step removes any lingering residue and contributes to creating a flawlessly smooth concrete and reflective surface, bringing out the full luster of the polished concrete.

Burnishing (Optional)

For an extra layer of gloss, consider burnishing the surface. This involves using a high-speed burnishing machine with a diamond-impregnated pad. The friction generated during burnishing enhances the concrete’s shine.

Maintenance and Care

To maintain the concrete smooth, you need to pay the cost of polished concrete floors by tking care of it through regular cleaning and periodic resealing.

Regular Cleaning

Preserve the glossy finish by consistently cleaning the polished concrete surface with a pH-neutral cleaner. Steer clear of acidic or abrasive cleaners, as these may compromise the shine. Regular maintenance ensures the longevity of the lustrous appearance, keeping the polished concrete in optimal condition for an extended period.

Periodic Resealing

To ensure long-term protection and uphold the glass-like appearance of polished concrete, consider periodic resealing based on traffic and usage. This maintenance practice safeguards against wear and tear, sustaining the aesthetic appeal and durability of the polished surface over time.

Tips and Considerations

Below, we have mentioned the tips and considerations for you to look at and make concrete smooth and shiny like glass.

Professional Help

Achieving a glass-like finish on concrete demands skill and the proper equipment. For larger or intricate projects, it is advisable to enlist the expertise of a professional concrete polishing contractor. Their experience ensures precision, efficiency, and a flawless outcome, particularly in projects with paramount attention to detail and expertise.

Quality Equipment

Investing in top-notch diamond pads, grinders, and polishing supplies will guarantee the best results. The effectiveness of these instruments is crucial in attaining a spotless and expertly polished surface on polished concrete.

Patience is Key

Polishing concrete is a patient and gradual process. Taking the necessary time, especially during transitions between grits, is crucial to guarantee a smoothing concrete floor. Rushing through these stages may compromise the final result, emphasizing the importance of precision and attention to detail.

Protective Gear

Prioritize safety by wearing essential personal protective equipment while grinding and polishing equipment. Equip yourself with safety glasses to shield your eyes, a dust mask to protect against airborne particles, and hearing protection to minimize noise-related risks. This precautionary measure ensures a secure working environment during concrete polishing processes.

Test in an inconspicuous area

Use the chosen equipment and materials to do a preliminary test in a small, discrete area before beginning the whole polishing procedure. This eliminates the possibility of more serious problems by guaranteeing that the selected tools and techniques produce the intended outcomes.


So, by now, we hope you know how to make smooth concrete that demands careful attention at every stage. Beginning with thorough preparation, which includes cleaning, repairing imperfections, and utilizing the right tools, the subsequent steps involve systematic grinding to achieve the desired smoothness. Polishing with progressively finer grits refines the surface, unveiling a radiant shine reminiscent of glass.
