Brother, those imperfections make it unique, original. Polished concrete is amazing. Awesome work!

[@Overpar73]

That floor is amazing and the time it took in labor is crazy!!

[@juliemarsh134]

Beautiful job! Thank you so much for taking the time to do this video.

[@joseoviedo1644]

Absolutely amazing. I kind of like the more in depth videos where you explain the process more clearly. It just makes it fun watching your videos when I know what exactly is going on. Other than that fantastic video. Cheers from Texas!

[@donspradley6912]

Oh this is amazing man! I can imagine the amount of gratitude that comes from doing a job like this!

[@paulmorton3259]

I’m planning on a concrete finish on my self-build home. But I’m pouring the slab from new. Can I achieve this level of beauty without the need of grinding the product down after. This is one of the best floors I’ve seen on KZbin. I’m from the uk and remember visiting nasa in Florida. Don’t know how they did it but they have a floor there under the space shuttle that’s an undulating polished black floor. Best I’ve ever seen ( apart from the floor exhibited in this video of corse).

[@ConcreteFloorSolutions]

Thank you for the compliment. Unfortunately, that finish cannot be achieved unless it is grinded multiple times, Unless there's a process I'm not aware of.

[@beautifuldegen]

I’m out in Oregon and need to do this on my home. Thanks for posting the process.

Waoo what an amazing job 👏.

[@williammonaghan7045]

So rather than watching videos,do you have any type of hands on training by chance? I have looked into a few different courses that are roughly $1500 a person for 5 day courses. Do you have any recommendations? You are obviously incredibly knowledgeable and that is so important when talking to customers.

[@TheGlowjoe]

Floor looks great. I’m redoing a 60,000 square foot floor for the first time and this just confirmed in my mind that I’m not capable of doing it lol. What is an good price per foot for a good quality polished concrete floor? We used a floor scraper to get up all the tile and the floor is very flat in good shape.

[@ConcreteFloorSolutions]

There is a lot that goes into pricing the floors. Condition of the floor, are there previous coatings, are there joints? Do the joints need to be filled? Location of the job. If you want to email me direct [e-mail], we can get in touch and I can go over it with you.

[@glengarbera7367]

Would the project moved along quicker if you used a 16 grit diamond on first pass rather then the 40?

[@ConcreteFloorSolutions]

Maybe, but then on the next pass you need to remove the 16 grit diamond scratches, which are typically much deeper than 40 grit. Every slab reacts differently. I'm not saying there is a right or wrong, everybody has their own technique. That is what I happened to choose for that job.

[@MartyHuie]

First of all, thank you for all your videos. I got a lot of information. I do have a question. Had my floors in my home polished, they started at a low number and was working up on the third day, it's when they vacuumed the floor and then applied a sealer of some sort, rectifier or something like that which brought out the shine and they said it was making it harder. That's when we noticed that some marks became apparent on the floor. Those marks were from tape that the general contractor had put down paper in some area to hold it in place. That tape had been there for a few weeks in full sun and they used a heat gun in order to pull it up because it was sticking to the floor at this stage. Those are very evident in the floor once they got complete. Do you know of any way to get those stains out? I hope I'm asking the right questions and explain

[@ConcreteFloorSolutions]

@@MartyHuie I understand completely, we had that happen on one of our projects before also. Unfortunately, stains are stains and typically are not able to be removed.

[@cmull96]

What kind of floor scrubber do you use? And do you always do that to clean up the dust?

[@ConcreteFloorSolutions]

on stain jobs this size, we normally use a floor scrubber with soft bristles to remove all dust and stain residue prior to guard application. on smaller jobs, we would use horse hair "cleanup pads" to remove the residue, but on a large project like this, its not practical.

[@cmull96]

@ thanks for the response! Love the content!

[@manavchopra1983]

How do you know when 40 grit or 80 grit needs to be done twice and not once? Thanks for a great video 😊

[@ConcreteFloorSolutions]

It is all about consistency. If you do your first grind and you see heavy stripes with inconsistencies, you need to grind the opposite direction one more time. The more consistent you grind your floor, the better it will look when you’re done

[@EVilTeddi]

exactly what type of stain was used in this video? was there a percentage of how black the stain was? I'm looking to get this exact look for my home garage for a more natural look instead of doing a metallic epoxy

[@jackhodges1030]

Why is it sometimes you put down a grout coat on polished floors and sometimes you don't? And can you tell if you're going to need a grout coat before you get into the job.

[@ConcreteFloorSolutions]

@@jackhodges1030 very good question, some concrete is very porous and sometimes you can tell before you start the job that you will need a grout coat. Sometimes you don't know at all until you start grinding, and when you look real closely you can see the pores opening up within the concrete. If you don't see the pores opening, typically you do not need the grout coat. The grout coat simply fills all those little microscopic holes / pores. I always say Concrete is consistently inconsistent..

[@jackhodges1030]

@@ConcreteFloorSolutions thank you for the answer.

[@rodneyram5172]

​@@ConcreteFloorSolutions Thank you for being so informative! When you say grout coat is it the same grouting used for filling up the gaps between tiles?

[@ConcreteFloorSolutions]

@@rodneyram5172 negative, that is joint filler used for filling joints.

[@gregholland8729]

Hey there! V good work. I’m curious about the perimeter- looks good, but can you help explain the process and product used and did the customer balk at the difference? Thanks!

[@ConcreteFloorSolutions]

The perimeter was the customers choice. Either hand grind the whole perimeter 10 times at a cost of +/-$5,000 additional or install a High performance urethane border at 1/2 the cost. Its MUCH easier than hand grinding, especially all the corners and down vents for the exhaust in the floor. Here is a link to the urethane, Black. concretefloorsolutions.com/store/urethanes/cfs-high-performance-urethane/

[@brandonsetters7608]

How much do you typically charge per square foot? Or is thst how the job is bid? What all do you take into account when bidding a job? I’m sure that it goes into what all has to be moved, and other things I am just curious.

[@ConcreteFloorSolutions]

there are MANY factors. Location, access, repairs?, joints? hard or soft concrete, coating removal, disposal or dust, power supply, grout coat needed? edging? gloss required, is the concrete smooth. (high and low spots affect the final look, uneven stone exposure). can range anywhere from $15 per sq.ft. for a small job to $3 per sq.ft. for a large job. We typically can polish 1,000 sq.ft. per day on average with a 32" grinder. 9 step, not including staining.

[@TheCureThatKillz]

What is the grout product you used on the floors? I am doing my first polished concrete floors I just started yesterday so I’ve been studying your videos to help guide me through the process.

[@directapprec]

Hey I'm about to do my first polish job. How did your first job go? How big was it? Was concrete level? What grinder did you use? Thanks

[@MeditacionPositiva39]

How much did you charge for the job?

[@skitzochik]

just gorgeous...really

[@ze_german2921]

Is grinding required on brand new concrete as well?

[@ConcreteFloorSolutions]

The only way to polish concrete is by grinding it. That is the process.

[@samuelrobinson7151]

what do you use for grout????

[@dognatious6153]

How did you apply the border without getting it on the walls?Masking? How did you mask the borders? Did you roll it, spray it, brush it?

[@ConcreteFloorSolutions]

We rolled it, the cove was not installed, so we could roll right up against the wall. We did tape the inside edges with blue painters tape and got a very crisp line.

[@alexguerrero4251]

Hello great job. How many days took you to finish a job like this?

[@ConcreteFloorSolutions]

We did this job a while ago. I believe it was about 10 business days.

[@hectormartinez1600]

man you guys are good ,let me ask you this when i need to stain i stop at 200 hybrids clean the floor, stain and densify but when i start polishing with 400s resins i notice that still taking a layer of the floor which i think makes the stain fades off ,now i am thinking to do all that after 400s then clean, stain and densify then run 800/1500s guard and burnish, any advise will be appreciated

[@ConcreteFloorSolutions]

I have always applied acetone based stain at 400 grit because I was afraid of grinding off the stain. After I apply stain and denify, I run a 800 grit Fenix pad then guard then burnish to 1500 grit. That is what we have been doing and that is what was done in that video.

[@palm8229]

How many days did you guys have into this project? Looks awesome!!

[@ConcreteFloorSolutions]

If I remember correctly, it was five days.

[@palm8229]

@@ConcreteFloorSolutions 2 guys 40hrs 10k sq ft thats hustling. I own Xmate Epoxy just had a customer ask if we polished concrete up to this point we haven’t but been debating getting into that aswell. The equipment needed isn’t cheap. We’re looking to expand our services.

[@edwardtemporado9806]

Thx Jason😀 I watch your videos a lot, quick question what would you recommend for a box generator ?😀

[@ConcreteFloorSolutions]

When you say box generator, you mean a portable one? Our large tow behind is a Wacker Newson G-70 to supply 480 V power. I would highly recommend that generator to anybody. As far as small portable generators, I can't say I have a lot of experience with them but the little experience I have is with Honda generators, they are extremely expensive but very high-quality.

[@jimfitzgerald2500]

Nice work. What product do you use to fill the cracks in the epoxy floor.

[@ConcreteFloorSolutions]

Thank you, we used Sase, all-spall 3 tinted black.

[@Interdimensionales]

Hello! For how long you let the guard dry before using the burnisher? And how fast do you walk the burnisher, what pace?

[@ConcreteFloorSolutions]

The guard normally dries within 5 or 10 minutes, (depends on temp and humidity) you can actually see it dry it happened so quickly. Remember it needs to be applied at approximately 2000 ft.² per gallon, super thin or else it gets streaky. A slow stroll is how I would describe my pace with the burnisher with a +/- 6" overlap.

[@MrKlarc19]

What's the difference between the 800g puck and the 800 grit disks you use?

[@ConcreteFloorSolutions]

The 800 grit pads are diamond impregnated and don't leave resin burn on the floor. Resin pucks leave resin burns sometimes.

[@MrKlarc19]

@@ConcreteFloorSolutions may I ask who your distributor is. We do a lot of natural stone work but it seems concrete is a whole different learning curve. I have 1 other question. When you grind the concrete after staining does that ruin the 800g pads?

[@ConcreteFloorSolutions]

@@MrKlarc19 does not affect the pads at all after staining. We used SASE pads and diamonds.

[@kaptincrazy]

New to this... What do you use for grout coat? Densifier? Heavy industrial use. Recommendations?

[@ConcreteFloorSolutions]

We use different materials depending on the job. This particular job we used Sase materials, all-spall 3 grout coat, sase densifier and guard coat.

[@kaptincrazy]

@@ConcreteFloorSolutions very cool,

[@MrBradfordwill]

Jason what did you use for the perimeter urethane? I need to start doing this. I'm polishing a 2200 slab home now and its taking about 2 hrs to run all the edges each time.

[@ConcreteFloorSolutions]

This is the material we use. All urethanes smell, so make sure everyone is aware the day you install it. This material bonds extremely well and has a long working time after it is mixed. concretefloorsolutions.net/shop/ols/products/cfs-322-high-performance-urethane

[@2012isRonPaul]

can u do a matte black too?

[@ConcreteFloorSolutions]

You could polish to 200 grit, that would be more matte, but it won't be as easy to clean either.

[@aaacustomdesign2729]

Haha looks like this one wore you right out man

[@ConcreteFloorSolutions]

It wasn't an easy one, thats for sure.

[@anthonyfernandez9709]

How do you price out each concrete floor do you have price list per sqft

[@ConcreteFloorSolutions]

There is no way you can give a set price per square foot. All concrete reacts differently. Here is a list of factors that I look at before I give a price. Job location, ease of access to the work area, is the concrete hard or soft, are there any repairs, are there joints and do they need to be filled, do they want stain, does the concrete need a grout coat, what grit finish do they want, how much edging is there, and then just the overall feel of how long the job may take. I can almost assure you, if it is an active construction site, you will be in everybody’s way, or they will be in your way the entire time. A large floor 20,000 square-foot is approximately three or four dollars per square foot average.

[@colbyabbott1760]

@@ConcreteFloorSolutions do you give customers prices before or after the job? Because you mentioned the softness of the concrete, just making sure.

[@ConcreteFloorSolutions]

@@colbyabbott1760 I always price out jobs before we do anything. I will sometimes have line items like “if a grout coat is needed” or “if repairs are needed” with pricing , and will also say as directed by owner so they need to give permission if there is an additional charge coming. We NEVER come back and say it will cost more than quoted.
