Understanding Concrete Polishing Grits

When polishing concrete is undertaken, the grits used serve as a measure of smoothness and light reflection. The term "grits" refers to the different levels of abrasiveness in the polishing process. Lower grits result in a softer and less reflective appearance on the polished concrete floor. On the other hand, higher grits contribute to a smoother surface and increased light reflection, resulting in a more glossy finish.

Typically, the range of finish grits used in concrete polishing falls between 100 and 3000 grits. As the grit number increases, polish and shine also increase. Therefore, higher grit numbers, such as 3000, produce a higher gloss and enhance the reflective qualities of the polished concrete floor. The selection of grits depends on the desired aesthetic outcome and glossiness desired for the specific project.

Level 1 - 100-200 Grit

Achieving a level 1 ground polish typically involves stopping polishing before reaching the 100-grit resin bond. When looking down directly at the floor at this stage, it will have a somewhat hazy appearance with minimal clarity or reflection. The surface will need a higher level of gloss and shine, and the focus is primarily on levelling the floor rather than achieving a polished and reflective finish. This level of polish is often preferred for industrial or utilitarian settings where aesthetics are not the primary concern.

Level 2 - 400 Grit

This stage marks the beginning of the glossing process for the floor. At this point, the surface should be free from any visible imperfections and exhibit a smooth and consistent sheen throughout. This finish is particularly suitable for warehouse environments, balancing aesthetics and long-term durability. Compared to a high-sheen finish, the gloss achieved at this stage tends to be more resistant to wear and foot traffic, maintaining its appearance for longer. In addition, it offers a visually pleasing result while prioritizing the practical considerations of a warehouse setting.

Level 3 - 800 Grit

The process involves using a diamond abrasive of 800-grit or higher to achieve this level of polish. The result is a significantly higher sheen than a level 2 finish, with noticeable light reflectivity. When viewing the floor from 30 to 50 feet, you will observe clear reflections of side and overhead lighting on the surface. In addition, this level of polish enhances the aesthetic appeal of the floor, creating a visually striking and reflective appearance that adds a sense of sophistication to the space.

Level 4 - 1500-3000 Grit

These highly reflective and clear floors are commonly employed in retail and office projects. Their high gloss finish not only enhances the aesthetic appeal but also offers the advantage of easy cleaning. This makes them an excellent choice for high-traffic environments where durability and maintenance are important considerations. However, owners must have a maintenance plan in place to ensure the long-term upkeep of the floor's appearance. Heavy foot traffic in busy areas without proper maintenance may result in visible traffic patterns or wear on the surface. The floor's pristine look can be preserved by implementing a maintenance strategy, maintaining its attractiveness and performance over time.

Benefits of Polished Concrete Flooring

Homeowners, retailers, big-box stores, educational institutions, and medical facilities increasingly opt for polished concrete as their preferred flooring option due to its numerous advantages compared to other floor coverings. Polished concrete floors provide excellent value and stand out aesthetically, making them a compelling choice. In addition, the combination of durability, cost-effectiveness, and appealing design makes polished concrete the logical and competitive flooring solution for many applications.

Eliminating Dusting and Efflorescence

While untreated concrete possesses inherent strength, it is susceptible to specific forms of damage and natural chemical reactions. For example, one of the ongoing concerns with concrete is its porosity, which allows for salt migration (efflorescence). This process can result in dusting, potentially harming surface coatings such as epoxies. However, by opting for concrete polishing, these issues can be effectively addressed at their root, mitigating the risks associated with dusting and preserving the integrity of the surface coatings.

Affordable

Although polished concrete may have a sophisticated and upscale look, the truth is that it is a cost-effective flooring option compared to many others. It has a similar initial cost per square foot as inexpensive alternatives like carpet, and its overall lifecycle cost is lower than that of other commonly used flooring types. This affordability is particularly notable if you already have a concrete slab that can be professionally polished, as it eliminates the need for additional materials or extensive preparation.

Stain-Resistant Floor

The porosity of concrete poses a significant challenge and contributes to a significant portion of its ongoing maintenance costs over its lifetime. However, by polishing the concrete, the surface is effectively sealed and becomes denser. This enhanced density allows the polished concrete to naturally resist water, oil, and other surface contaminants, even without additional protective measures. As a result, the polished surface becomes more resistant to staining and easier to clean and maintain.

Durable

Polished concrete is renowned for its exceptional durability, particularly in manufacturing and warehousing facilities. The solid composition of polished concrete enables it to withstand heavy foot traffic and even the movement of heavy equipment without succumbing to damage. As a result, polished concrete floors are highly resistant to chipping, scratching, and other forms of wear and tear. Furthermore, when the polished surface is properly sealed, it gains resistance to chemicals such as alkalis and acids, which helps prevent corrosion and maintain the integrity of the flooring.

Brighter and Reflective

Enhanced reflectivity provided by polished concrete floors not only improves the effectiveness of safety painting but also offers long-term advantages in terms of energy control. The increased reflectivity of polished concrete contributes to superior ambient lighting, giving your facility a fresher and cleaner appearance. This enhanced lighting makes the space more visually appealing and creates a more inviting and pleasant environment for visitors and workers alike. Additionally, the improved lighting can help reduce energy consumption, leading to long-term benefits in energy efficiency.

Environmentally Friendly

Polished concrete floors are considered eco-friendly due to several reasons. Firstly, their installation and upkeep do not require hazardous chemical coatings, cleaners, or adhesives, reducing the release of harmful substances into the environment. In addition, this makes them a sustainable choice for indoor air quality.

Additionally, polished concrete floors are energy-efficient. The reflective properties of polished concrete enhance natural lighting, reducing the need for artificial lighting and lowering energy consumption. This energy efficiency contributes to a greener and more sustainable environment.

Overall, the absence of hazardous chemicals and the energy-saving characteristics of polished concrete floors make them an environmentally friendly flooring option.

Low-Cost Upkeep

Polishing your concrete floor has a significant cost-saving impact over an extended period. The dense and compact surface of polished concrete eliminates the need for aggressive scrubbing to remove stains, reducing maintenance expenses. Moreover, the characteristic sheen of the floor can be maintained without the requirement of waxing or stripping, saving you the investment and effort associated with these traditional maintenance methods. Choosing to polish your concrete floor results in substantial long-term cost savings.

Healthy

Polished concrete, being sealed and nonporous, remains dry and prevents the accumulation of allergens, dirt, and bacteria on its surface. Unlike hardwood and carpeting, polished concrete contains no harmful volatile organic compounds (VOCs), contributing to better air quality. In addition, its smooth and nonporous nature eliminates crevices where pollutants can gather, making polished concrete a favourable choice for improved indoor air quality.

Enhancing Old Floors

Treating your concrete floor, whether through epoxy flooring or concrete polishing, is a beneficial way to prolong the lifespan of the underlying slab. Polished concrete, in particular, offers exceptional compressive strength and effectively resists erosion from various factors. In addition, through a mechanical polishing process, the top layer of the concrete can be ground down to rejuvenate its appearance and integrity, contributing to an extended service life of the slab.

Customizable

While you might have a preconceived notion of how polished concrete floors appear, the possibilities for their final aesthetic are limitless. The appearance of a polished concrete floor can be customized to suit individual preferences and design preferences. For example, you can choose from a range of shine levels and have the option to select different aggregates, colours, and patterns. Additionally, you can add a personal touch to the floor by incorporating decorative engravings or graphics, allowing for a truly unique and personalized result.

Minimal Operations Disruption

Each floor coating and treatment process comes with its specific set of requirements. For instance, certain paints may require a primer layer and a designated curing period. In contrast, the time required to polish concrete can vary, but with dry mechanical polishing, a concrete floor can be ready for use immediately after completion. This eliminates the need for additional curing time, allowing for a more efficient and convenient turnaround.

No Toxins, Cleanup, or Risks

Many businesses delay extensive flooring projects due to concerns about safety hazards. However, concrete polishing offers a solution that minimizes these risks. Unlike other flooring treatments, concrete polishing does not involve harsh or abrasive chemicals, and it does not produce dangerous waste products. Additionally, the ventilation requirements for the treated area are less demanding. As a result, most concrete polishing projects can be completed within a relatively short timeframe, typically taking only a few hours or days. This allows businesses to improve their floors efficiently without compromising safety or causing significant disruptions to their operations.

When Polished Concrete Isn't Your Best Option

Polished concrete is a highly suitable choice for the majority of flooring projects. The only reason to consider an alternative flooring type is if your facility has exceptionally specific and unique requirements. We have already discussed such scenarios, which typically require a high-performance surface. If you require epoxy flooring or industrial coating, it is important to note that these surfaces may incur higher maintenance costs as they tend to deteriorate over time. While epoxy has gained popularity in residential applications, it is primarily utilized in commercial facilities, including:

• Aeroplane hangers
• Places where cars are made
• Kitchens for businesses
• Decks and front steps
• Garages
• Places like laboratories and drug stores

Some people find concrete floors uncomfortable in their homes because they have less cushion than other traditional flooring types when standing for long periods. Since concrete doesn't absorb sound as well as other materials, people living in homes with concrete floors often add rugs, curtains, and even wall panels to reduce noise.

With a big investment at stake and many things to think about, hiring an experienced concrete contractor is important to help you choose the right flooring for your space.
