A concrete grinder is an abrasive machine for grinding and polishing concrete and natural stone. Concrete grinders can come in many configurations, the most common being a hand-held general purpose angle grinder, but it may be a specialized tool for countertops or floors. Angle grinders are small and mobile, and allow one to work on harder to reach areas and perform more precise work.[1]

There are also purpose-built floor grinders that are used for grinding and polishing marble, granite and concrete.[2] Concrete often has a higher sliding friction than marble or granite which is also worked wet, therefore with less friction. Floor grinders can cover large surfaces, and they have more weight on them, making the grinding process more efficient.[3][4]

Attachments

All concrete grinders use abrasives to grind or polish such as diamond tools or silicon carbide. The diamond tools used for grinding most commonly are diamond grinding cup wheels, other machines may use diamond segments, mounted on varies plates, slide on diamond grinding shoes and for polishing are usually circular Resin diamond polishing pads. The use of diamond attachments is the most common type of abrasive used under concrete grinders and come in many grits that range from 6 grit to the high thousands, although grit is considered by the insurance industry as the highest shine to apply to a floor surface.

Wet or dry usage

Concrete can be ground wet or dry,[5] although dust extraction equipment needs to be used when grinding dry.

To grind concrete dry, a grinding shroud can sourced for most angle grinder sizes,[6] and floor grinders usually have them inbuilt. This provides the necessary vacuum attachment where one can connect a vacuum or HEPA filter-equipped vacuum to capture the fine dust produced when grinding dry. Of course concrete can also be ground wet in which case no vacuum is used. An issue with dry grinding is that is can be time-consuming as is a slower method of keeping the diamond tools cutting and the fine dust particles quickly blocks up the HEPA filters in the vacuum. Continuously stopping to clean or replace filters can be time-consuming and this is where a dust separator can be beneficial. It is connected between the concrete grinder and the vacuum cleaner and works by capturing the larger particles of concrete in its drum, so only the fine particles reach the vacuum cleaner.

The benefit of grinding concrete wet is that it requires less attachments than when grinding dry. The water makes the dust particles heavy by turning them into a slurry or paste and prevents them from being dispersed into the air.[7] This significantly reduces health risks from breathing in concrete dust.[8]

Dust precautions

When grinding concrete it is important to ensure steps are taken to mitigate exposure to concrete dust. According to the Cancer Council, approximately 230 people develop lung cancer each year due to past exposure to silica dust at work. Fine concrete dust contains silica which is very harmful to the lungs and can lead to silicosis so all effort should be made to avoid breathing concrete dust. In construction, mining and other industrial type jobs that expose workers to dust and small particles, one should wear a respirator mask commonly known as a N95 mask, FFP2 mask, P2 Mask or KN95 mask to protect from inhaling concrete dust. This is because such a respiratory mask can block 94-95% of non-oil based particulates that are larger than 0.3 microns.[9] Concrete Dust particles can be as small as 0.5 microns, which is larger than 0.3 microns, which means that a N95 respirator provides effective protection against concrete dust when fitted properly.[9]

For green building methods many regulators have seen the benefit of using concrete grinders that are designed to finish concrete to a very stable wear surface, that can safely be used for many years as a floor or tabletop surface. These machines are sometimes powered by 240 volts or higher as they require motor power larger than 120 volts can supply. Some machine are powered by liquefied petroleum gas such as used on forklifts so that they can be run in well ventilated areas without a power cord, but these machines usually have fewer features that a fully electric unit.

Facilities managers in commercial settings have a lot on their plate, from ensuring the safety of employees and customers to keeping costs under control. Choosing the right concrete floor is an important decision, and there are several factors to consider.

One of the most important factors to consider is the purpose and function of the floor. For example, a warehouse may require a different type of concrete floor than a retail store or a hospital.

Of course, costs are also important, and one should consider both the cost of the concrete floor installation as well as the total cost of ownership for the floor. The cost of the floor should be considered in relation to the expected lifespan of the floor and the budget of the facility.

Concrete Floor Installation

The cost of installing concrete flooring in commercial and industrial spaces can vary depending on factors such as the size of the space, the complexity of the installation, the type of concrete or coating used, and the location of the project.

Generally, the cost of concrete flooring can range from $2 to $20 per square foot, depending on the factors mentioned above. The cost can be higher if additional treatments, such as coating, staining or polishing, are required.

It&#;s important to work with a reputable contractor who can provide you with a detailed estimate based on your specific needs and requirements. They can also advise you on the best type of concrete or coating to use based on the specific needs of your space.

The Concrete Slab

Every coated concrete floor begins with a slab of concrete. This is one of the most predictable of costs, as concrete is one of the most basic and ubiquitous of building materials. Typically, you can expect to pay between $4-$7 per square foot for the initial slab, depending largely on the quality of the concrete, as well as its final thickness. As with most building materials, per-foot costs will go down as the amount of concrete being poured goes up.

Considerations Beyond Concrete Flooring Costs

Durability is another key consideration when selecting a concrete floor. The floor should be able to withstand heavy foot traffic, machinery, and other types of wear and tear.

Safety is also an important factor to consider. The floor should provide a safe surface for employees and customers, with slip-resistant properties and the ability to withstand spills and stains.

Aesthetics are also important, as the floor should complement the space and reflect the brand or image of the company.

Maintenance and cleaning should also be considered. The floor should be easy to maintain and clean, reducing the time and cost associated with upkeep.

There are several types of concrete floors available, each with its own unique advantages and disadvantages. It&#;s important to consult with a reputable contractor who can advise on the best type of floor for the specific needs of the space.

By working with a knowledgeable contractor, facilities managers can select the best floor for their specific needs and budget.

Concrete Flooring Contractors

Experience and reputation are key factors to look for in a contractor. You don&#;t want to hire someone who inexperienced, that could lead to a disaster. It&#;s important to look for a contractor who has a proven track record of delivering high-quality work and excellent customer service. Checking online reviews, customer testimonials, and references from previous projects can give you a good idea of the contractor&#;s reputation.

Specialization is another important factor. Not all concrete flooring contractors are created equal. Look for a contractor who has experience working in your specific industry or setting. You wouldn&#;t want to hire a contractor who specializes in installing floors in homes to install the floors in your industrial warehouse.

Certifications and licenses are also important. The contractor you choose should have all the necessary certifications and licenses required by local and state regulations. It&#;s important to ask for proof of these certifications and licenses to ensure you&#;re working with a reputable contractor.

Quality of materials is another important consideration. You don&#;t want to end up with a floor that looks like it belongs in an abandoned building. Look for a contractor who uses high-quality materials and is transparent about the materials they use. Make sure to ask if they have environmentally-friendly options available too.

Cost and timeline are two major factors to consider when choosing a contractor. Look for a contractor who provides a detailed breakdown of costs and timeline, and who is willing to work within your budget and schedule.

Communication and customer service are key. You don&#;t want to work with someone who is hard to get a hold of or who provides subpar customer service. Look for a contractor who is responsive, communicative, and willing to answer questions and provide updates throughout the project.

Choosing the right concrete flooring contractor is a big decision. Be sure to do your research and ask for references. With the right contractor, you&#;ll end up with a floor that looks great and will last for years to come. Remember, a bad contractor can give you a &#;concrete&#; example of what not to do.

Commercial & Industrial Concrete Coating Costs

When you&#;re looking for commercial and industrial flooring, there are often no better flooring options than resin-coated concrete. With a huge variety of coatings available, including customizable mixes, there&#;s an option to fit any business use. The question is cost.

The good news is that coated concrete is still among the most affordable options in commercial flooring, but the exact costs will vary depending on a variety of factors. No online article can give you an accurate estimate &#; for that you need to contact concrete specialists &#; but we will attempt to break down the various cost factors and how they are likely to impact the final price.

When looking at coatings for your concrete, there are three primary options: epoxy, urethane, and methyl methacrylate (MMA). Each has their own costs, although as with the concrete slab, per-foot costs will typically decrease as floor size increases.

Epoxy Coatings Cost

Epoxy is the most basic and common type of coating, and also the most cost-effective to install per square foot. Epoxy is cheap and ubiquitous, with the basic materials as cheap as $2/ Sq. Ft, up to $5-$6 for basic mixes. Labor is similarly inexpensive, adding anywhere from $1 to $5 per square foot.

Urethane Coatings Cost

Urethane is a plastic variation, with good tensile strength and damage resistance. Urethane is substantially more expensive than epoxy, but also offers longer life and less chance of being damaged. Between materials and installation, it can go as low as $6-$7 per square foot for large pours, or up to $13+ for smaller or customized batches.

MMA Coatings Cost

MMA is in-between epoxy and urethane in terms of costs, typically being in the $5-$10 range for installations. It&#;s also in-between them in performance &#; slightly less strong than epoxy, and slightly less resilient than urethane, for a moderate price. MMA is particularly good at standing up to cold temperatures, and it cures quickly as well.

Aside from the space being covered, the confounding factor in these prices are the mixes of flooring materials. A wide variety of additional materials can be added to the resin blend, including:

• Silica for extra traction
• Anti-microbial protection
• Multiple colors
• Reinforcing materials for heavy-duty floors
• Metal or stone flakes as design elements
• Specific additives for extra chemical resistances

As customization increases, so do the costs.

Downtime Cost Factors

If you are retrofitting an existing floor with resinous coating, it&#;s also important to factor in the disruption to your own business. The floor cannot be used while it&#;s drying and curing, which will add to the costs.

Epoxy is the slowest to dry, taking at least 48-72 hours.

Urethane typically takes 24-48 hours to cure.

MMA can dry in less than 24 hours, making it the best choice for rush jobs.

Also, all resinous coatings are vulnerable to moisture and humidity while curing. For jobs where the concrete is exposed to the elements, or within an open building, weather conditions can slow down drying further.

Is It Time To Replace Your Concrete Floor?

For situations where a company already has a concrete slab, the other major consideration is whether the slab should be replaced.

Concrete is strong, but brittle and easily damaged. In addition, it is extremely easy to stain, due to its porous nature. This is one of the major reasons to coat the concrete, as a coating will extend its lifespan significantly.

A concrete floor typically needs to be replaced if:

• The slab has major cracks or potholes
• The ground has shifted beneath the slab, causing it to tilt. In this case, re-grading the ground will be called for.
• The slab has become stained
• The slab has allowed toxic chemicals to seep into the ground below

Otherwise, if the slab is in good condition or only has minor damage/staining, it can typically still be used for a resinous pour.

Once the concrete is protected with a resin, its lifespan increases drastically. Even a low-cost basic epoxy pour will last at least a decade, and more expensive high-strength mixes could last 20-25 years without major replacement or repairs.

Overall, this makes coated concrete one of the most economical choices for commercial flooring. To obtain a free estimate for the costs of your own flooring installation or upgrade, contact Black Bear Coatings And Concrete to learn more.
