If you want to do an epoxy floor in your garage, you NEED to do this if you want it to turn out well and last. I'm talking about concrete prep. A lot of times, companies or DIYers will acid wash to save time, but if you want to do it right, you're gonna want to diamond grind. So, that's what we're doing today! I learned a lot about what works and what doesn't, what's easy and what will just make your life harder. So let's get into it and start The Ultimate Dream Garage Build Series!

#diy #dreamgarage #epoxyfloor
Just did this a couple months ago, my first house and epoxied garage. I used Hellfire Concrete Coating which isn't an epoxy but the same prep work. Definitely agree and recommend renting the Diamabrush maintainer. A couple things that I learned though. 1. Even though you're doing a wet grind, I would highly recommend anyone to wea a silica respirator as silica dust is no joke to you lungs. 2. I found that filling the cracks (if you choose to do so), angle grinding, and then the floor maintainer yielded the best results. The maintainer smooths out the angle grinders 'kiss' marks. 3. Give the garage plenty of time to dry out which is a little hard since we've gotten so much rain in TX this past week. Just because its dry on top doesn't mean all that water you've injected with the power wash is gone. 4. The day you're putting down the primer, run your shop vac over the entire floor and/or broom sweep several times to get all the remaining bugs/dust/crap off the floor. 5. Have help when you're putting the epoxy down and make sure you have extra of whatever you need (brushes, rollers, etc). Since its time based, you may not have time to stop and make a trip to the store, especially with the COVID stuff, if you screw up. 6. Full flake is the only way to lessen the effects of UV on epoxy, at some point it will yellow and it doesn't matter what product you use. The quality of product and amount of UV determines how long it will take to yellow. My next garage, I'll be porcelain tiling as it takes just about the same amount of work, around the same price depending on what PEI rate you go with (recommend at least 4), and is the most durable of coatings. Added bonus is you have unlimited amount of time to do the work and can do it in sections, unlike epoxy. Downside is its a higher learning curve of work.
With preping if the home is a new build do you recommand grinding the floor?
You read my mind - I’m skipping the epoxy and going straight for the porcelain tile.
@@shaunmurray7677 Very late on the responding here. You likely do not need to grind and could get away with just acid etching but you will need to wait a certain duration before you can epoxy new concrete. I believe many recommend waiting at least 2 months or more. It would be recommended to perform moisture tests prior to ensure the slab has had enough time to cure.
@@mechanicalcanvas A mechanical grind is almost always required per manufacturer's tds. Only low quality products would allow acid etching as proper preparation.
i got the idea from you to do my floor in my garage and to be honest that is the best thing i ever done
Removing paint and prepping interior concrete floors for stain and polish. Had the same problem with the dust shroud bristles being too long and ended up cutting them. And I thought about doing it all using the angle grinder, too, but it kills your back. Will be renting the floor maintainer and Diamonbrush next weekend. Thanks for the video.
The satisfaction in this video is top notch...
The only person that can make me excited to watch concrete prep.
I did my best 😁
Great video. Thanks, this will help me prepare my 700sq ft garage floor.
The prep is the most important and the most annoying part. I did this same process for my 2 car garage. Full process took me about a week to complete and I swore i would never do it again but i get a ton of compliments from everyone that sees my garage. Look forward to the series.
I feel you dude haha. I think the biggest pain was dealing will all my stuff. If I was doing it in an empty house I don’t think I’d complain much lol
@@motonosity yup, had to deal with the same issue. Moved all my stuff to the basement during the process. All worth it in the end tho. I also bought a 4 garage kit instead of a 2 garage kit so it was a very thick layer so it should last longer. 2 years strong so far.
@@narftastic still standing strong?
@@ryanharter711 yessir. 👍🏼👍🏼
The only one who spent money in this type of crisis ...
Motonosity= yes
I need my build garage! haha
Fox Dye you might as well finish all those diy projects that you started. I mean you have to be home anyway.
Are you not getting your sheetrock/walls all wet?
Nicely done - yup prep is king. Did this with my garage and tooled back and forth with having a "pro" do it - but - figured meh .. if I screw it up then I'll have someone re-do it. TL;DR - mine ended up awesome.
Can't wait to see the finished masterpiece. Just bought a house and looking for ideas for my garage since I don't have a good imagination lol.
Heck yeah man!
Hope you and the family are staying safe! I’ve been looking forwards to this build! We just got back to Idaho after leaving Austin.. definitely going to take notes and get my garage set up soon! My garage is going to be half gym and half motorcycle.. so will be different, but still excited for this series none the less!
Might not be that different 😉 Thanks for the well wishes dude
Awesome video, thanks for uploading been a subscriber for many years and these DIY videos are dope , hope theirs more to come!
There will be :)
Thanks for sharing. Going to use a maintainer now on mine. Lol about the millions of attachments to get the dust collector to work. I have spent probably $100 on different hose and pipe connectors to make my bucket collector.
I love the use of the football cleats +1
At 12:00: I think the likelihood of someone coming to steal stuff is very small....... next video: SOMEONES STOLE ALL MY STUFF?’
Why shop-vac it if you have to powerspray it all again after you're done? Why not wait until the very end to shop-vac it? Great vid, thanks!
Hi everyone. Concrete coatings professional here. Not trying to critique my guys process here however, just want to make everyone aware:
1- concrete dust is incredibly super fine. Shop vacs do not have appropriate HEPA filters, yes that’s right you need multiple, to help make sure your air stays clean. Why do you need it to stay clean you ask? Because that super fine dust creates silica which if inhaled can cause MAJOR respiratory problems. So, just keep that in mind when you get the urge to do things like this yourself. :)
2- That Home Depot Diama brush unfortunately is garbage. Simply because there’s not enough weight behind the machine.
3-“ floor maintainers” as he described it, are not designed for this kind of work. They’re made for cleaning, not grinding.
A professional with the right tools would be able to get this garage done in less than a day with even better results. That includes prep, and coating installation.
Be safe out there and remember, cheap labor isn’t skilledC and skilled labor isn’t cheap :)
How much on average for this job?
Exactly! I paint professionally and I leave the concrete work to the concrete experts! I'll expoy the floor for the client only after being professionally grinded then I'll finish the magic.
I'd question any so-called pro that puts down an epoxy floor including grinding/cleaning, in half a day, as it requires a lot of down time for drying from the cleaning, between putting down layers or primer, epoxy, sealer, etc.
This is why a lot of times I choose to not use a so-called pro even if money isn't the issue, because they will cut every corner they can to get the job done faster to do more jobs. 2 years later when the epoxy starts coming up, good luck getting ahold of them, let alone forcing them to fix their shoddy work.
With the right knowledge and tools, this kind of job does not need a so-called pro.
Added bonus of wet grinding is a lot less dust everywhere too. Don't let the days get too hot before you epoxy, and fill as many cracks and holes as you can before hand. What will you be using for anti-skid since you weren't a fan of the chips?
Your a very trusting man leaving your things out over night.
paintslinger 104 u see his neighborhood? nobody’s stealing anything😂
Red Baron exactly
Use water
works great
SWISSTRAXX!!!!!!!!!!!
Thanks for the info. Hoping for clarity. Your video you mentioned floor maintainer. Then in parts used in project floor polisher is mentioned. Which is the one you used?
I can't wait to see how it turns out. I have been thinking about doing my garage once my house is done being built.
This seems like such a huge PITA. This would be something I'd pay a professional to do, if I could afford a nice house lol
A good way to afford a house to to do stuff yourself that you can easily do and takes very little skill and just some time and elbow grease, like grinding your concrete floor.
Will the Diamond grinder remove existing floor paint?
Yes along with a degreaser
Can't believe you even considered doing an entire 3-car garage floor with a hand grinder!
How do you still have the gift wrapping on the Honda? That was like 2017?
It was 2018. And because I felt like it lol.
Motonosity Christmas is not a time but a feeling. A feel ya! Hahaha
Can you show a pic of the diamond grinder? It looks different than the one I rented from Home Depot
what exactly is the point of the pressure washer???
What type of pad or brush are you using? Is it a diamond pad?
Can I still sand if the primer has already been put down
what are your lighting plans?
im gonna do mine next weekend but im gonna use a acid wash to clean the garage floor before I lay down epoxy
How do you know when to stop grinding
Great channel thank you for the useful content
Can we see more on the super Moto?
yeah lemme just finish this garage first lol
Epoxy greatest thing ever made! I use that shit on everything lol Love it next you will be doing your countertops! Which I did and Looks great!
Yeah man makes a massive difference! Already thinking about it for the counters in our rental property.
Did you manage to do this all on one grinding wheel for the rental?
How long did it take you and roughly how much square-footage is your garage? I wanna get an idea of how long I should plan to do my 1000 sq-ft.
Hi! is there a reason you didnt just hire someone to do it for you???
Remember uv will yellow and break down epoxy no matter how uv resistant the epoxy is (keep the garage door closed as much as possible).
I have a 10 x 20 concrete floor with a concrete surface profile of between medium scarification and heavy scarification. What grinding blades and procedures do you suggest for making it smooth for an epoxy coat?
Nice Vid...did you have a concrete sealant over the concrete requiring you to have to diamond grind??? I am planning to epoxy too, just the stuff from home depot, but I think my concrete is sealed. From what I've been watching, grinding the old sealant is the only way. Thanks in advance!!
Why wet it use a diamond grinder from sunbelt no wet no mess
enjoyed the video!
DIY = Daerah Istimewa Yogyakarta
May I ask which diamonds you used for the first cut?
Looks like a diamabrush head
Great video! A new subscriber here.
Would be awesome if you could chop this down to < 5min vid
They put 3-4 spacers in the package with the dust shroud.. you put them under the wheel to make it match to the bristles
Lol
I have an existing epoxy floor, but I would like to change the color. Do I have to remove the old color entirely?
Yes from all research I have done, if you already have epoxy garage floor or paint, you should get the big grinder in video or sand blaster.
You changed your shoes halfway through the video. 🙂👟
7:50 what is that on the wall by the ruckus
Rocket88 tesla charger? i think
Sprinkler system control unit
What motorcycle is that?
4 1/2" grinder is not made to do this. 7 1/2" would be best for small areas.
Is there anything you can’t figure out! You do it all! I know it will come out awesome because I honestly haven’t seen you do anything half ass yet!
What happened to the grom?
That floor machine is not taking off enough concrete. it looks like it is smoothing instead of cutting and leaving tooth for the epoxy to adhere to. Pros use much bigger machines with very aggressive carbide cutters.
Thanks or uploading this video. I'll be doing this work within the next few weeks, and my research, all the way down to the nitty gritty details such as modifying the angle grinder dust buddy, led me to the same conclusions as you. However, I've decided to go with polyurea, rather than epoxy. In fact, given your attention to detail and inclination to do thorough research, I'm surprised you didn't choose polyurea as well. Any particular reason why not? Anyway, thanks again; I appreciate your video.
🚨 FYI pro tip *Use good hearing protection* I’ve used buffer/floor maintainers 35+yrs
*Just use them* !!!!!!!!
I'm seriously not looking forward to having to do this on the new garage floor. -_-
Hit it with a 3000+ PSI pressure wash first with a surface cleaner. Then use the buffing machine
@@llamacebu216 Why do that when the diamond grinder is going to literally remove the entire top layer of the flooring and anything attached to it?
So I don’t have to an acid wash if I just use the floor maintainer? I have a few stains on my concrete... would I have to do an acid wash instead?
Get in contact with Matt @obsessed garage, put some swisstrax flooring down 👌🏻 or get your garage completely “dialed in” by him
I’m not a fan of those floor tiles. Don’t like how they feel and don’t like that you can’t just sweep junk out
Use ppg
Did you use the Coating Removal disc from Home Depot or just the Concrete Prep disc? Their website description is unclear which works with the floor maintainer (presumably both).
I'll be doing my second garage epoxy floor next week. The first one I did was on a new build home and the floor was ready to go - pretty easy with very little prep required. The one I'm doing next week is older with remnants of an old pre-existing epoxy floor that's flaking up everywhere. I think the coating removal tool is good enough and I'll etch separately with citric acid but the concrete prep disc says it etches. Thoughts?
Do you acid wash after you grind
Thought acid etching is what people would do when they didn't want to grind. The grinding removes any paint/sealer/etc and gives the surface the rough texture needed for the epoxy to adhere to. I've heard too many stories that etching simply doesn't do enough to create a surface for a good bond and epoxy ends up flaking away after just a couple of years.
no
No, stay away from acid. That's why he grinded
I miss read the channel, thought it was leggari or stone coat.
Edit: since you're dealing with epoxy resin, why didn't try making your own carbon fiber? New idea, new thing, more video, more money
Whatever you do do not use home depot epoxy
Great video! I'm going to tackle this project this weekend, starting with grinding the sealed garage floor. Do you remember roughly how long it took you to grind your 3 car garage?
How long did it take you?
@@samm3561 It took me about 2 hours to hiring the floor, but I think that's a little overkill. Once I figured out how to best use the grinder it went pretty quick
@@kevrobinson2000 Seems like the prep is the hardest part.
@@samm3561 yes for sure. Once the grinding is done, each day gets easier. I put primer down and it took 45 mins. Next day is epoxy and it goes on the primer very easy. Last day is topcoat and thats a breeze
To much work to much trouble I will stick to garage floor tiles. Racedeck.com or Swisstrax.com
Really want to go that route, but they have their own issue: water getting under causing mold/mildew, popping up, especially when you have aa car on them and turn the wheels, costly for what they are compared with the cost of DIY epoxy.
My weird ass ocd wants the floor to look wet for good after lol.
You and Dan both
Well it’s about time. I love your videos but you definitely needed a better space.
I’m couldn’t watch your video talking to much without showing,dislike
6:45 hello 🛵😘
;) lol
#satisfying?
Maybe lose the "How to" from the title? or the DIY ? both together doesn't seem right.
Oh dear!
How to do the minimum work with the minimum equipment and still expect a professional job, and then tell everyone to do it the same way you did
Yo you know when you live in a white neighborhood because you're not afraid to leave your stuff outside. People go through my trash bruh lmao 😂
Lasted 2 minutes...does anyone make a simple go-to guide versus some guy staring into clthe camera talking crap not relevant to the DIY? Cripes.
After all that I think maybe just hire a pro? Nice job though. Seems like quite a bit of time- 3 days just getting ready
Saving 2grand sounds better to me
First like
Pin this comment
the reason why i only chemically etch concrete, and only grind when it is uneven
Heard way too many stories about how etching doesn't really create an ideal surface for the primer/epoxy to bond and it ends up flaking away after 2/3 years.
I guess if you're doing it professionally and don't care how it looks 2 years later than etching is fine.
do not listen to this guy, epoxy goes on bare cut concrete do not use a primer!
Editing this busy must have been a bitch when you can’t record more than 2 sentences at once. Couldn’t watch it
Hyper-speeding thru the actual only part of the video of value makes no sense. We can't learn any technique from this.
There's no real technique, just go slowly over the surface until you have a clean surface with even texture needed for the primer to properly adhere.
Sorry but this is Too long and it’s only part one. Maybe just do a separate “steps” video under 4 minutes on the side…for people who know their tools but just want a quick layout of the job
Rent a floor grinder prep work is 3 hours max hahah vs 2 days
I know!!! Shit is painful to watch😂😂🤦🤦
