This is a VERY interesting video. While I find the differences in the techniques of polishing vs epoxy covering fascinating, I would be even more interested in your takes on the reasons for selecting one over the other. In essence, I would like to hear your take on the pros and cons of polishing and sealing vs epoxy coating. I would like to have my 2 car garage floor either epoxied or polished. Thank you for the video, and in advance for any reply!!

[@joshjones8047]

Thank you. Polished concrete is considered a high traction surface when clean. If it gets wet while dirty (dust or dirt is all it takes), it will be very slippery. Another drawback to use in a garage is exposure to oil or whatever else may fall off a vehicle. My choice for a garage would be a coating. It’s resilient and able to be made slip resistant, clean or dirty. Polished concrete is perfect for dry areas. It’s a durable surface as long as it’s kept clean and not subject to chemical attack. If the area is expected to be spilled upon, a coating is the best choice.

[@slackjaw4270]

​@@joshjones8047Thanks. I have a bicycle shop with old concrete floors and previous owners tried carpet and linoleum which both failed. I've considered coating the concrete. Is there anything I should consider in an epoxy?

[@joshjones8047]

@@slackjaw4270 I think your choices are pretty open for an epoxy floor surface. There’s the option of opaque coatings such as a solid color, decorative quartz, or flake floor. The durability of each will be acceptable for that environment and traffic type. There’s also the option of what’s called a ‘grind and seal’. This is s durable system as well, provided the resin type is one that’s appropriate to the traffic. Coatings options for your shop are pretty open and more up to you for the aesthetic benefit a specific system will support.

That’s a good point. Epoxy is a more chemically resilient surface (when topped with a urethane or Polyaspartic). Polished is better for abrasion resistance but has little to no chemical resistance. The choice of which is better relates directly to how the floor will be used. Thanks for the helpful input. It is appreciated.

[@joshjones8047]

This is a tough one to address since there are different conditions that will make one a better candidate over the other. Excluding the aesthetic differences, the primary difference between each is chemical resistance. A coating system can be formulated to resist a harsh acid. Polished concrete, by contrast, will etch from pro longed exposure to orange juice or ketchup. As for abrasion, either can be damaged if they aren’t kept clean. Dry storage and/or limited exposure to chemicals- either will work. Expected exposure to acidic chemicals- a coating is the best choice. I hope this helps to clarify what was omitted.

Simple and all basic information about the processes love this video... Epoxy vs polished, mechanic home shop... Work on diesel trucks etc... I'm worried about chipping, does the densifier help strengthen the concrete? Expoxy brand recommendation, also does gasoline effect either of them? Your recommendation for my scenario.

[@joshjones8047]

Thank you very much for the compliment. With regard to the polished surface and its ability to resist chipping, it all depends on the force of dropped tools or metal parts. Densifier makes it more difficult to scratch the surface, but does not affect its ability to withstand impact. An impact resistant coating can withstand dropped parts, but the system’s performance is largely based upon thickness and type. As the system becomes more thick, of course, the cost to install rises too. For resistance to gasoline, a coating is the only way to prevent surface stains or absorption. Polished concrete will have little ability to hold back any chemical. Thanks again for the positive response and the great questions.

Hi Josh, Thanks for such great comparisons and explanations. Between both, which one is much higher costing inclusive labor cost please? Thanks

[@joshjones8047]

Thanks so much for the compliment. The question is difficult to answer precisely because labor rates vary by region. I think it’s a safe generalization to make that polishing will be more expensive than the coating system shown because of the steps (labor) required to do it. Where the polish has a potential for being a better value is in its abrasion resistance and related maintenance costs. Still, the choice of polish or coating should be first made for its ability to withstand the expected traffic. Cost would be a factor in the decision but only after determining what system the floor needs. Thanks again.

[@DoctorWonka]

This sounds super laborious. I am curious how long the whole process normally takes (for an average garage, for example)?

[@joshjones8047]

That’s a good question. Either process is pretty involved. A two-car (400SF) being polished takes a day if appropriate sized equipment is used. This assumes the floor does not require repairs or grout as was shown. If a coating is being done, it’s a two day (faster reacting chemicals allow it to be done in a day) process if the floor requires no repairs. To clarify about the demonstrated coating system, this one is more appropriate for an industrial application. A residential appropriate system is only two or three total coats.

[@joshjones8047]

That’s a good question. Densifier will help as long as the surface is not covered by any membrane forming sealer. As far as benefit from the treatment, it will help to make the bonds between hard aggregates more complete. If it’s well consolidated as a product of good placement, the only other concern would be stain resistance. There are penetrating sealers that can help to limit staining. As far as polishing, there is always the option to do that in areas where more reflectivity is needed/wanted.

[@soundz9992]

Have you ever done an exposed aggregate floor and clear epoxy and added the grit clear sand? I love the look of the exposed aggregate but need some grip when garage floor gets wet, Thanks.

[@joshjones8047]

I have not done this personally, but that type of floor can be done quite easily. I would suggest you consult your epoxy supplier about clear coatings that are made to be slip resistant. Many industrial applications require a slip resistant clear coat for their floors, so your requirement should be easy to meet. For creating your own system I would recommend that you follow a reputable supplier’s system. The concept of adding sand to a coating is quite easy, but some coatings will actually fail sooner because they do not have the ability to encapsulate an added material. Thank you for the great question.

[@ChicagoEpoxyCoatings]

Thank you for the video! I have a quick question i was hoping you may help. We are currently dealing with a bit of a botch applying a Poly top coat over our clear sealer coat. We tried to stretch out our Poly Top Coat too thin resulting in squeegee marks/roller marks. There are also some blotches of Poly in certain areas of the floor that started to harden before we were able to spread it. What would be your best recommendation for fixing these issues? I assumed we would sand out the areas where we have roller/squeegee marks to the best of our ability and then reply a Top coat. Can you help us solve this nightmare?

[@joshjones8047]

Happy to help. It seems to me the first thing to do would be to sand down the areas where the dried poly has created elevation inequalities. Once that’s done, the only way to not see the treatment there would be to overcoat the whole floor with another poly top coat. This probably means sanding the rest of the floor to prepare for the new overcoat, but I can’t see another way to hide the area that needed help to be smoothed. Hopefully this helps.

Coatings provide chemical resistance that polished concrete cannot and offer a more diverse range of color choices. They can be made slip proof too. To me it’s all about the environment which floor choice is the most appropriate. I hope this was helpful, but I’m also happy to discuss further as needed. Thank you again.

[@joshjones8047]

Thank you for the request. My advice is a coating that is chemically formulated to resist damage or staining from the chemicals you expect to be present. For abrasion resistance and grip, it’s also something to verify in the coating’s formulation and design. If it were my floor, my choice would be an epoxy and urethane system (like in the video). While it’s not the hardest wearing surface, it’s one that can be any color of the rainbow, is easy to clean, has good surface traction, and will be plenty durable for low speed vehicle traffic. As always, surface preparation is most important to any product performing to its full potential. Your choice of product and installer is also important so that the quality of placement and chemistry provides you a durable surface.

Is the polished concrete slippery? - I'm converting my garage to a rental unit. Demolition the old slanted concrete and after plumbing and radiant heat tubes installed - a new concrete pour. I really like the look and (non)maintenance of the polished floor - but I'm concerned about potential slips and accidents.

what diamond disk numbers do i need to polish my terrazo theres so many numbers, can i do it with only 3 steps??

[@joshjones8047]

This is a good question. The beginning step and ending step depends upon the terrazzo’s current conditions and any sealer that may be present. Terrazzo floors are traditionally honed to a 100 or 200 and sealed. In the case of polishing, some can be specified to have a polish to 3,000 grit. Common Diamond progression can be: copper 50, 100, 200, resin 400, 800, 1800, 3000. There could be seven steps possible or maybe only two or three. It depends upon current condition and final surface requirements.

great video but the cost is never mentioned. cost of polished vs epoxy.. i know it costs between 2-4k for most garages to epoxy with lifetime warranty but your company has not mentioned it even once.

[@joshjones8047]

Thanks for the input. The cost varies for either process based upon market and system. Also, this video is a few years old and prices have gone up. Thanks again-

[@charltonheston969]

This is why most homeowners can't do it themselves, you have to spend 20k on equipment & all the different diamond grits.. I'm just going to buy the cheap diamond infused scrubbing pads & rent a 17" machine from home depot for my basement laundry room. It definitely won't look as good as this but I'm not to picky & it should be pretty Shiny after a coat of sealer & 3 coats of wax

[@joshjones8047]

Good point. Wax is easy to touch up and plenty appropriate for the area. Thanks for the positive comment.

Josh A very informative video and educated me a lot. I am looking to do my Garage floor and came across this video. I have sent you an email with some of the questions I had. I am posting here as well. I saw in a forum post shared by one of the Car Garage shop owner and he recommends polished concrete along with dye (if need for color) and sealing vs using epoxy. Is that a better alternative than epoxy? For epoxy, what top coat is the most durable and prevents yellowing over time? - Polyurethane or Polyaspartic? Thanks again for the great video!

[@joshjones8047]

Thank you very much for the kind words. If a floor is going to be colored and sealed, we call that a stain and seal. I prefer to use stain (mineral pigment) rather than dye because stain will not fade from sunlight, it is permanent its color. For the top coat, I would recommend either a polyaspartic or polyurethane. Epoxy will scratch too easily, but polyaspartic and polyurethane were made to bear traffic. Thank you again.

[@davidedwards3052]

Which do you like better for an automotive shop floor? I have a hobby shop where I maintain 10 cars. My 80x40 shop has a sealed floor, but it stains from all the oils over the years. It's a working shop, so it will take a lot of abuse. I like the ability of the epoxy to repel oils, but don't like it's propensity to chip and mar. The polished floors I've heard stain.... Where is your business located?

[@joshjones8047]

@@davidedwards3052 thanks for the request. For a shop and chemical repellency, I’d choose for a coating. Regular maintenance and correct cleaning chemicals will help to extend the coating’s appearance but they will eventually need to be replaced. Our business is located in Morris IL.

[@seanfaulk8641]

So which is better for a garage floor where cars will go in and out and some welding and so on? Epoxy, epoxy with flake, or polished concrete??

[@joshjones8047]

That’s a great question. My preference is a resilient coating because it’s chemical/stain resistant. It can also be made slip resistant with a topcoat additive. For the welding, a protective shield would be needed for either surface. Potential exposure to that amount of heat will damage a coating or polished concrete.

[@seanfaulk8641]

@@joshjones8047 what would that be?

[@joshjones8047]

@@seanfaulk8641 it all depends on the look that’s preferred. A flake floor and solid color epoxy will both perform the same way. The only thing that’s different is the appearance. Flakes are popular because they offer a little more interest than a basic one color floor. Still, the topcoat that protects either type is a system’s workhorse. This is usually a urethane, but that all depends on the installer’s preference.

[@fatimahs_bestie]

For a bus stations waiting room (foot traffic), which one would be better in terms for durability? Epoxy/polished concrete? Which one is more slip resistant when wet?

[@joshjones8047]

Thank you for the question. I think a polish would be very durable, but slip resistance will rely upon the floor being kept clean. A polished floor is a high traction surface wet or dry, but if dirty will be slippery. A coating would be fine for durability as well, but this also must be kept clean. The biggest mistake with floor choices is still remembering that no floor can be attractive and safe if it is not clean. Thank you again for the request. Please revert if you need further advice.

[@zyou8er]

Does polishing make the floor slippery?

[@joshjones8047]

That’s a good question. Testing of polished concrete has proven it can pass OSHA and ADA coefficient of friction minimums. This is true when wet or dry as long as it’s clean. The short answer is no, it’s not any more slippery than waxed tile. Because it’s so smooth, though, a dirty and wet floor will be a hazard.

[@rob1andrews]

What is the relative cost difference between epoxy and polished floors?

[@joshjones8047]

That’s a good question. Polished concrete usually starts at $4/SF, but that’s more along the lines of commercial spaces exceeding 10,000SF. To coat a floor with a single component, clear, aliphatic urethane, it’s maybe around $3/SF. These numbers will be very different based upon local labor rates. In terms of performance and environment, polished concrete is a poor choice where chemical exposure (including oils) is expected. Coated concrete is a poor choice where abrasive surface traffic is expected.

[@cjhification]

Thought you were mad to start with, then realised you were talking in milli-inches. When you first said 7 mill I thought you were using the international standard millimetre, I thought he's crazy 7mm of any resin coating will be super expensive. Then remembered you talkin in milli-inches in North America.

[@totheknee]

That's a good catch. 7 mil is about 180 microns, or roughly 0.2 mm.

[@margiehilton3370]

Thank you for doing this video. I have a 40yr old house and the basement concrete floor was colored enhanced applied when built. I thought an epoxy was the way I would be going until I contacted a flooring company and they recommended polished concrete would do better inside the basement of a house. Sighting it would hold up better. I like the cinnamon color of my concrete but would like to see it slightly lighter if possible. Even a gray concrete color would be desirable. Is polished concrete advisable on an existing color enhanced concrete floor?

[@joshjones8047]

Thank you for the request. It’s hard to say if your floor will polish to your satisfaction. The only way to know how it will look is to do a mock-up. Of course this means time and expense to do the work, but it’s all that can be done to provide a representative sample. As far as the color or overall shading, it’s been my experience that a polish will make a floor darker as it is refined. For the environment, there’s not much there that can damage a polish. It’s breathable and abrasion resistant. It’s only weakness is damage that can be caused by chemical attack. Orange juice, ketchup, soda (a few examples) can all etch the reactive surface. Some extra protection can be applied to minimize damage caused by incidental exposure to acidic compounds , but regular exposure can cause surface damage. Thanks again for the comment and request.

[@Philly_s_Best]

Which would you prefer on low traffic garage floor?

[@joshjones8047]

Good question. For a low traffic garage, I think an epoxy system is the best choice. It’s resilient and durable to make it easy to clean and able to handle low speed auto traffic. Thank you for the question.

[@ethos79]

Price wise, which one is more expensive per square footage?

[@joshjones8047]

Great question. Polished concrete is usually more expensive because it involves more labor. In countries where labor is cheaper, coatings are more expensive.

[@sirakberhane1420]

Hey Josh, Great work. My question is would a polished floor be too slippery for a commercial Laundromat business?.

[@joshjones8047]

Thank you for the compliment. A polished floor wouldn’t be slippery wet or dry when clean. If it’s anticipated that chemicals (soap) and water will regularly be on the floor, then a coating with an anti slip additive would be better. It wouldn’t have to be as involved a system as shown in the video. It could be a one or two coat aliphatic urethane system.

Is this finish slippery or safe as far as disabled people falling on it?

[@joshjones8047]

That’s a good question. Polished concrete has been tested using a dynamic slip meter to verify it can meet OSHA and NFSI standards. With this said, it’s my understanding that actual testing of a polished floor is only able to be certified when tested at each location it’s installed. So, yes, it meets the standards. Each location where installed, though, would have to be tested to protect the property owner if litigation were to occur.

[@the_microfibre_man]

Great video. I want to do polished concrete in my garage at home. If you were doing polished concrete in your own garage what grind level would you stop at? And if you were to use a clear sealant, would you choose polyurethane, polyaspartic or epoxy? Thanks in advance for the reply.

[@joshjones8047]

Thanks so much, Greg. A floor that’s been ground and sealed is a great look. Polished concrete is one that has no topical sealer that can wear. This means it is still prone to staining by oil, road salt, etc. Your idea of a floor that looks like natural concrete, but is protected by a chemically resilient top coat, is a good one. My preference is to grind the floor to expose the sand and then topcoat with an aliphatic urethane. There is the matter of best surface preparation practices to remove all dust prior to coating, but an aliphatic urethane is the most user friendly coating there is to apply. It’s a durable commercial grade product that can be incorporated with anti-slip additives (recommended for a garage). Your local SW store can offer suggestions about their aliphatic urethane or you can feel free to email me for more specific instructions. I will plan to shoot a video detailing this same process. I’ll shoot it and post it for you. Thank you again.

[@markvincentcocjin]

What would you recommend for parking hangars of battle tanks? Epoxy or polished concrete or is there something else out there?

[@joshjones8047]

Mark Vincent Cocjin that’s a tough environment for either product. I would recommend a slab treatment that is generally called emery top. It’s a mixture of very hard minerals and specialty binders that can handle extreme abrasion. It’s an industrial flooring product one might find in heavy equipment repair areas and trash container depots.

[@fz1xr650lyz426kx500]

What if you have fiber in your concrete?

[@joshjones8047]

That’s a great question. Polished concrete containing fibers might be a little less clear in shine, but it can still look quite good. As far as coating a fiber reinforced slab, it’s a bit more tricky. The fibers can be torched, but the remaining ones will absorb the first resin coat and stick up. I’ve been told that they can be sanded after the first coat, and then should not be a problem again.
