been in the industry 20 years. this is a great video showing how much work and equipment you need for a "small" job. Resin burn sucks. glad you showed how the edges look from concrete placement and how its not the Polishing guy not doing it right. Great job.
Thank you for watching and thanks for the great compliment.
20 years you say that's a 🤥
Man 20 years that's a veteran in that industries
When you said you used a 400 grit copper to remove scratches around the edges you lost me.
@@j4209-y5o I don't get how he could be lying about 20 years. I'm in the industry and know multiple guys in their 30+ years. Two of them retired last year.
Nice to see professional tradespersons who take pride in their work.
Thank you for noticing and thanks for watching.
I've been in flooring for close to 30 years as well and I can tell your style, you know your stuff and you take pride in a good job. That is why I'm suscribed. On a side note I'm just getting into polishing and coatings. I'm writing a proposal for a stained concrete polish job and I noticed one area has craze cracks. Can you grind through those?
@@1stainless Yoo im late to this but im young in this industry only 23. have been only polishing for 4 years. Depending on where the crack is what I usually do is cut the crack a bit (so that the material bonds) then fill it with your best patching material. When doing this mix it with dust from the floor your doing so it can get the same tone. during this what im still expirementing is putting rocks in the crack mix so when grinding it there's some aggregate and it hides the crack if that makes sense.
Jason,as a floor installer looking to find other aspects of work ,I personally appreciate that you show all of the steps! I appreciate your videos tons man!
My pleasure, thanks for watching.
Jason and Jeff did a great job on this, my garage / studio floor of about 350 sq ft. They revealed some cool character, cracks and varied aggregate. One never knows what the final result will be, except it will shine. Well worth any cheaper solution. No bacon-break for them . . . but did give them one of my home made pizzas for lunch.
And it was delicious. Thank you for the business, i’m glad you like it.
I work for a concrete polishing company and love it. One day I hope to be able to own my own business. Your videos helped ease my mind before I started my job so I wanted to say thank you for your time into making these videos and sharing your knowledge!
My pleasure, I’m glad you enjoyed it
Is it possible to get started with no experience
Great content brotha! 👌🏻 I’m a small general contractor getting ready to do my first concrete floor grind & partial polish on a 13,000 sqft showroom for a big customer or ours. 😬These videos are gold!
@@Justadude1904 good luck, I hope you learned something from it.
@@ConcreteFloorSolutions thank you! Just realized you guys sell all the products as well! I’ll be contacting you soon.
When the diamonds burn you need to lower your speed and spray water. Saves the diamonds. Been doing polish floors for 9 years. You learn tricks from vets. Great video and nice work guys
I actually demonstrate that exact process in many of my other Polishing videos
holy cow i did not expect so much machinery for concrete polishing. Nice setup!
I do exactly the same but in the UK....Same kit, same issues.....Only just found your channel and about to binge watch...Nice work Sir,..👌🏻
Thank you for watching.
I just started doing this trade last week. They were willing to hire someone with no experience and I'm not going to miss out on the opportunity. Thanks for the homework video!! Hopefully I make it😅
Did you do the job? Any advice for skilled first timers?
@pulaskifarm W he fired me because I crashed my car and didn't make it one day (he was fishing for some reason I think he thought I was a thug or something). I did it for about 2 weeks. Advice would be wear proper PPE and if something doesn't feel right, look on the OSHA site and make sure they're to par with everything. I had no respirator grinding concrete getting silica dust into my lungs. Thats my only experience with it, so I can only really hope this was just a bad operation, but PUT YOUR HEALTH 1ST!!! Sorry I couldn't help more tho...
Sorry to hear,,,keep at it and follow your interests
@@ChaserRocks I'm going to try. I think I need to get out of oklahoma🤣
I’m having my clinic floors done, and I had no clue why polished concrete floors cost so much. I had no idea what was involved. Thanks!
They cost a lot bc it’s a lot of work. A lot of man power put into it and the finished product is amazing. I use to do it but had to stop just do to so much traveling and having a young daughter. I very much miss it. It’s fun
@ADD1SCHXRMSXO it's only fun on the final stages lol
How much was it?
How much was it?

If you come across really hard concrete..wet grinding is the best option. We also use HTC machines, most often we use the 950, we have 15 of them and smaller ones of course.. There have been good machines.You seem to know what you are doing, and thanks for the great work samples.
That’s a 500 CFM vacuum the larger 854 I believe gets up to 750 CFM but you aren’t getting 500 CFM through that 3 inch hose probably closer to 400. 500 CFM is when you have the 5 inch hose being utilized. So when you strangle it down, it will lose air flow in CFM, although you will increase the velocity of the air in the hose. But that being a fan motor doesn’t have a lot of lift and strangling it really affects its performance. Also, we start with a 1618 or even lower just so we can get down through the cream faster.
Hey man just FYI I watch about every video you publish and just get so much knowledge from them. thank you
Thanks for watching
Probably the best video out there for what's involved. I'm now certain I'm just going to grind my floor level to 120 grit and paint it.
I love how organised you are. You've absolutely fine tuned your craft
This business looks serious and professional and worth what ever you charge
You are so detailed in your work, a true artist. What a wonderful job.
Watching and learning from Australia great work guys
Liked seeing your trailer and you showed all job details well
Hey guys, watching and learning from Australia - thanks for the content!
Thank you for watching
Ayyy same boat!
I do this type of work. Polishing and epoxy, and trust me, this stuff will make a man out of you. It definitely isn't easy work. I love it though. Great job on the floor by the way, looks good man 👍
Very informative. As a career documentary cameraman may I suggest you have a go at positioning the camera at floor level so we can better see the aggregate in the concrete which will highlight the changes in texture with each pass of the grinder. Modern smartphone cameras have good macro capability. You may have to invert the camera to get the lens really close. With these closeups play around with a small battery powered led soft work light positioned to one side.
very nice polishing like it I m a polisher from ontario canadia I like the way you doing it.
We use 100 grit transition puck. The 100 resin I find is not very aggressive. Although we also use thehundred grit after the 40 grit diamond bus, saving a step
You can’t buy that at the store. Looks amazing especially when furnished.
It’s concrete .. everything is placed on site
@@teebo5298 wtf does that even mean??!!?
Nice gear and good hardworking knowledgeable team. I’d highly recommend getting with the Australians and look into the husqvarna hiperfloor system. Worx+ is the name their runnin under after the sold to husky. Oh and FYI 400 won’t ever remove scratches.
I wish you were in Arizona. You are a class act.
Every floor is unique!
Great work.
Take and run soap down both sides of your joints before you put in the joint compound. Clean ups a snap. Try it
Thank you Concretefloorsolution for up load this comprehensive video. I am currently getting quotes from different companies ( sorry we live in Australia ) to do my floor, I now known what to expect from them. Thank you again
Great video,thanks.I want my front deck ripped out and would love polished concrete stairs front and back of house.I wasn’t keen on the cracks in floor but looks unreal otherwise.
Love the exposed aggregate. Great job! Beautiful look.
Them racattacs are a life saver when it comes to hand grinding the edges. We usually use an edger. But sometimes the edger doesn't give as great of results as hand grinding it does. Just depends on the floor really.
Your equipment is amazing. Clear sign your winning as a business 👏
Thank you for sharing!! Very interesting and good job and explanation!! saludos desde Argentina!!
I love this look! Great work guys.
That’s amazing . A lot of work .
When doing my wooden floors, on my 30's property, with a stand up belt sander, at 32 grit, I used up 25 belts, then only 2 belts on 40, 80 and 120 grit, (and my finish required I stop there 😁) so very much understand the struggle to get the first layer sorted.
Amazing work
Just a tip next time grind those edges a little more use water just like you did with the big grinder
I love running easy edges as well especially with these high polish
I hit 30, 50, 100, and 400 easy edge then run my pads on the edges to make sure everything matches
Easy edge are the 💩
You skip 200???
@@davidbolton4930 don’t think they make 200 easy edges only pads but correct me if I’m wrong
Nice attention to detail, gentlemen.
I like seeing stuff like this and knowing my jobs easier. After first cut depending on how bad the concrete is, all you need is 100s, 400s and 800s. 200s in between 100s and 400s are literally just a waste of time
Unless you are leaving scratches that won't be removed from the 400s, which is why we were using the 200s. We used to do that years ago and we landed up getting residual scratches, now we do the extra grind. It's much easier to do the extra grind before you realize you should've done it three steps ago.
The rack attack makes life so much easier!!!!!!
Love the blastrac collector
I found this to be a lot of help to do this exact same work for a factory thank you
Couple questions... ( Finisher here) I'm about to pour a 320 sq.ft. floor for polishing) 1) obviously I gather from you that a newer floor can be easier without the hard trowel finish. IYO , what is ideal to start the polish ? Ex: 3 days after pour ? Next day?
2) what type of finish to make it easier? Smooth steel trowel ? Will finish lines come out if you have a small line?
3) you never mentioned any sealers when done....does that floor you did get any type of sealer for shine, or is it not needed due to slip factors?
That floor you did , was it a 1 day job for that many grinds?
Thanks , love the video you did.
Typically you should wait 30 days before polishing concrete, I have already done it at 20 days and it seems to react well. If you start grinding too early, the surface will be so soft it will pull the stone out of the surface and probably do more damage than good. I have had great success doing a smooth steel trowel finish, without burning the surface with the steel trowel (Power trowel). We always apply a densify or after the 150 grit metals concretefloorsolutions.com/product/cfs-concrete-densifier/ and then a guard at the 800 grit stage:
concretefloorsolutions.com/product/cfs-polished-concrete-guard/
then burnish the floor. Do not use a sealer that creates a film, once you do that it defeats the whole purpose of polishing because you have a coating on the surface. True polished concrete is exactly that, a polished concrete surface.
I love this video. You guys are true professionals. What do you guys do with all the dust that comes out?
I can polish a floor that size with my hand trowel . and the cracks are from the heat when you are grinding the floor . if they where just there they would be every where .
Thanks for posting. No filling of pin holes in the concrete or densifier step? Please let us know.
What do you guys use for your joints

Great work guys, very professional and tidy.
How long did this project take?
And how do you estimate how many days a project will take when it comes to the size in Square footage?
Do you have a general rule of thumb?
Thank you, that project took approximately eight hours on job.
Typically for smaller jobs we get about 1000 ft.² per day. You can increase production dramatically by doing a larger area. Larger floors we can do about 2000 ft.² per day.
We also have a second large grinder that we will use on larger projects.
was the propane varnisher the 1500 grit why do you change machines. great video
Yes it was, the burnisher is needed for the final polish, the grinder has too much down pressure to burnish the floor.
Pretty amazing job yall do. Quick question.
What do you all do with all the grinding dust that's left over from all your jobs?
trash, all inert dust from stone and cement
Love your videos ! Thank you for your detailed explanations! My wife loves these floors except she is wanting a low luster , not so much shine - how is this accomplished ?
My friend's high school built in the 1930s as part of the depression works program has polished concrete floors that are still glossy.
I always wondered how this was accomplished and now I know!
Aside from filling in joints to polish over, can pits in the concrete be filled in?
absolutely. either by using a grout coat or simply filling each pit prior to polishing. We did that every day.
That's awsome......if u guys ever in south Texas let me know.....u got the job !
That looks awsome. My question is how you would do a bathroom as it needs a fall to the drain.
Thanks again for the video. Once the sealer is applied on ground floor slabs, have you ever experienced moisture migrating to the walls ? Can a sealer prevent the slab from breathing ?
@@OptLab the sealer used in polishing are actually what they call a microfilm. It allows moisture to pass through, but it is not a waterproofing sealer by any means.
If you need to stop moisture from passing through, you need to apply a coating, which would be a moisture vapor barrier or any of our epoxy kits on top of it
Keep making the videos. I always learn something from you guys.
welcome to the channel
I work for Diamond polishing company his equipment was antique thank God it was only one job
@@donaldcurtis9229 this video is almost 4 years old and yes, I made a big investment a long time ago and the equipment lasted the entire time without a problem.
As far as I know, planetary grinders still spin in the same planetary motion.
And that was not my only job I ever did. We've done hundreds of thousands of square feet.
What is the point of your comment?
Thanks for the insight into the job! You guys did great:)
Great job guys. The attention to detail is awesome.
Firstly, this floor is absolutely stunning. You do amazing work and love how informative this video is!
I’m having my floor done currently, after they stripped the paint off the concrete, the team says that my floor “cannot be polished”, is this possible?
They’ve told me the floor is turning to dust when they go over it with the machine. I see how many passes you had to take to get the polished look - they’ve tried to convince me I cannot achieve this look. Any advice or advisement would be greatly appreciated!!! I would love to end up with a perfectly imperfect polished concrete floor like you’ve shown us!
Thanks I’m advance for any help
Great work gentlemen! Awesome video
Did you close down shop? How much did you spend on bits per year during operation? And what are all the grinding types did you support. A 3 step a 7 step and a 1 step
@@zorartfamily1374 we sold all of our equipment and now only sell our epoxy flooring materials in our online store
concretefloorsolutions.com
We typically only did nine step grinds
Good day. If the client was looking for a light salt and pepper exposure think it would have been best to start with a resin 30 and run wet. Then run wet resin 50 and 100, densify with way more densifier. Let the densifier rest over night then run up to 800 dry and guard. I realize this makes the job 2 days instead of one but in reality it is much less work and a much more refined look. It’s one man and two half days for a floor this size. When running metal bonds, the deep cut exposes more pours, more pours equals less refined. Also, if the concrete is obviously that hard just run wet. Water tricking the metal bonds is a mistake. It will help with the cut a little bit but it tempers the metal making the bond harder therefore not as good for hard crete. When the metal does shed, it will often leave a burr and a scratch pattern.
Very nice job . But can I ask if if you drop red wine on the floor. Can you easily remove it without making spot?
If you wipe it up quickly yes. If you leave it set, it will stain just like red wine stains everything.
@@ConcreteFloorSolutions okay I will tell my daddy. Thanks you
what if you use a stain guard ? I myself use it I think it protects tbe floor
I like your trailer , wonderful job 👍
Thank you for watching
Great channel. Do you use the shot blaster much at all ?. Thanks
We use the shot blaster a lot to clean out joints, and for commercial jobs for heavy duty surface prep.
Racatac is a must for this type of work
Thanks a lot for the video.
Do you use triangular sander machines or oscilating tools for the corners ? How do you make the surface even for the corners ?
we used a 4" grinder for corners. typically your trim will cover anything exposed after that.
Keep it up man! Love watching your vids! I always learn so much from your efforts! Stay safe out there!
Thank you for watching.
you can add some color to create darker finishing.
Correct, we have some videos of staining and polishing too. Acetone based stains work the best for us.
I just figured this was done with one pass over and some epoxy. Boy was I was wrong.
Looks great. Do you put down any kind of compound before burnishing? Wax or something?
@@hobocameltoe Apply polish concrete guard, then burnish.
concretefloorsolutions.com/store/surface-treatments/cfs-polished-concrete-guard/
Polished concrete is so attractive.
Is your competition I have to have to hand it to you very organized great work and we can all learn something from you
Is that an Aztec burnisher? We’ve been doing business with them for over 30 years. One of the best propane burnishers on the market.
Yes, aztec lowrider. Great machine
Thank you so much for this video. We are considering polished concrete for our garage. I have a question: is the concrete still porous and easy to stain when it is polished? How often does it need to be repolished to keep it looking nice? Thanks! Do you recommend it for garages (cars) or just for work spaces?
Typically we do not recommend polishing in garages because it really does not provide any resistance to oil stains, etc. Every concrete slab is different so it may or may not be porous. There is no way to know until you are done. If it is done properly, you may not ever need to redo it. If your concrete is soft and porous, you might need to re-polish after five or 10 years. Concrete is very inconsistent
Your working style is very professional in india we work like this
Cool dude...cool tools...thanks for the expertise...nice to see the country...is that concrete dust reusable?
What is the depth of the cut? How do you cut the concrete when there is floor heating system with water pipes running under the concrete? Thanks, great videos.
very carefully... That is something you would need to talk to the concrete contractor about when they pour the concrete. They should know the depth of the water lines so they can cut the proper depth joint.
Thanks, I am in the process now to plan the concrete flooring and thats one issue bothering me@@ConcreteFloorSolutions
If I want a smooth acid-stained interior floor that absorbs rather than reflects sunlight (i.e. matte, not glossy), do I even need to polish it like you're doing in this video? It seems like an alternative is to apply sealant then wax. With the fine polishing that you do, I guess wax isn't needed, or even sealant? But maybe this fine polishing method doesn't work with acid staining? (because it polishes away the staining). Thank you for your opinion on this.
I have no experience at all with acid stain so I really don't feel comfortable making a recommendation.
Great job!to hide the cracks we use colored sealer.Works fine and helps if the customer aint happy.Check Husquarna polished concrete system,you gonna like it:)
Awsome. Now do you apply an epoxy finish or some sort of sealer to it from here? Or do you just leave it
Do you need a dry/wet vac if you use a little bit of water to cool down the diamonds? Or can you just use a fry vac?
if you were doing it correctly, you should not be vacuuming any water up. the water actually vaporizers from the heat of the diamonds so it should all be dry dust if done properly. We only used a dry vacuum system, and never had a problem
How long does the shine last?
Indefinitely as long as you keep it clean and don't use chemicals on it. The actual finish is the concrete itself, how long does it take to wear the surface off of concrete with foot traffic? Typically a very very long time
Nice guys. Well equipped, very professional
Joint filler Great Products to , I forgot the name !
The versaFlex it’s so good to
Very cool work actually going to be joining a small company that does this same thing here in a few days very exciting and interesting work!
Good luck, thanks for watching.
Great videos! You are obv true professionals. I have recently purchased an Edco 22” grinder and am planning on doing a few large floors with it. I am totally new to this, but have been a contractor for almost 20 years doing almost everything from the ground up. Quick question. In my very limited understanding of this process, the actual grinding bits go to 140 grit, and then you switch to pads? Also, how do you match your hand grinder grit to your floor grinder? Thanks again for your helpful videos, and any advice you might provide.
Hello I'm about to pour a slab for a customer that plans to have it polished. Do I do anything different? Hand rod or vibe strike?
More aggressive in the mix ect?
also can you demonstrate how to get the floor accurate? asking because , i work withing a bunch of groups who want , polishing they way, but i need one that is THE most accurate !
Terrazzo look, with the gator skin look finish
It is possible to polish it after the slab is poured and before the walls are built on it? Seems like it might be easier to do it that way if possible?
That is always preferred. The only issue is, the concrete needs to cure 30 days before you polish it. That creates huge delays for builders not being able to construct any interior walls for a month. In most cases builders can't wait with the interior construction.
I hope you charged for all the extra work. If you had known that they wanted exposed from the beginning you could have requested the proper mix and it wouldn't have been so difficult.
Do the high grit diamonds get as hot? Or do you only use the water for the low grit?
Typically the higher grit you go, the less friction and less heat. It's normally the 40 and 80 grit diamonds we use water on.
On a very rare occasion we do use water on 150 grit metals.
If I was looking for a similar look for an exterior slab, but not glossy, what would you recommend?
Greet video. We have faced many issues with concrete polished floor shading. How do you control the tone and shade of the concrete polished floor?
Excellent question. You don't, the concrete itself dictates what it's going to look like. You are polishing a natural concrete.
I always say Concrete is consistently inconsistent. You can't change the way it's going to look. That is always the first thing I tell the customer before we ever do a polishing job. I can only make it shine, the rest is out of my control.
@@ConcreteFloorSolutions I appreciate your quick honest and professional reply. I guess it is time that we highlight what you have just said to our customers here in Malaysia. Many thanks 🙏
Excellent work may I ask for that particular job? What was the cost to the customer just to have an idea because I would like that done about the same square footage
