How to remove glue/epoxy/paint from concrete floors, DIY style.

- In this video I show a real-time example of the results you get when you grind the top layer of concrete off your floor. After scraping, sanding, sweating and using every nasty chemical within reach, I finally came to my senses and got myself set up with some grinding equipment. This is effective for removing pain, glue, epoxy, mastic, thin-set and even for leveling out high spots in your shop and/or garage floor. I got by with just the one grinding disk for my two-car garage and it still has TONS of life left! Hope this helps anyone else looking to revamp their floors! Thanks for watching!

Man you're the only one who shows how and more importantly what you need, links etc. You were incredibly helpful.
as soon as I watched this video I went to Home Depot and got the dust shroud and the diamond wheel and got to work on my bathroom floor. Worked like a charm and it was fast! Thanks for sharing your info!
This is the only place I found this information on TH-cam. Thank you for taking the time to do this video! You are a very good teacher
Well that’s awesome! I hope it helps!
I’ve been debating that dust removal attachment for my grinder since yesterday and you just sold me! Man, I’m amazed to see your video stays clear of concrete dust!! It makes such a mess and that crap goes everywhere without it. I already have the other equipment so now I’m convinced and ready to get this going! Thanks again.
I'm glad it helped! The first day of grinding I had dust everywhere. As in, the shop, everything we own, the neighbors house... everywhere. This saved my but big time. Good luck!
Great point about doing it this way versus using a buffer. Once I started planning this project I realized that my floor is too uneven for a buffer and that I need the grinder to remove the really bad high spots. Awesome video. Thank you.
Very well executed video. Informative and detailed. Thank you for sharing your knowledge and adding all the links on the description.
Exactly. I've just finished two days of trying to clean up a big spilled (and hardened) tar mess on my garage floor, left over from previous owner. I've been going at it with a scraper, muriatic acid, expenive chemicals, etc., etc. Finally, it hits me: GRIND this shit off! I'll be getting my grinder (need one anyway) and disk in the very near future. Thanks for confirming the idea! And thanks for all the links. Very helpful.
Awesome video just what I was looking for!
Great information and exactly what I needed to know for my project. Thanks for the video!
Super helpful, bro. Thanks for making time to share this. It’s exactly what I was looking for.
Super helpful, thank you. You just saved me a lot of pain.
Wish I found this video 3 years ago - tempted to re-do my garage this way
Thank you so much! I have crappy patchy epoxy paint on my concrete floor but need to self-level it for porcelain tiles but nothing sticks to epoxy properly. This looks like the perfect solution. Off to get a new grinder and correct disc!
Oh, My Goodness!! Thank you so much. This is of great help. I've been trying to remove outdoor carpet glue wasted money on products and nothing has worked. Thank u, thank u, thank u!
Did it work???
holy shit, awesome video, i love your style and i needed to know all this info!
Super helpful! bought similar stuff last week, will start the job today
ok so this is the first video of yours that i've watched... i'm diggin the background music.
good no nonsense video. thank you.
Your a saviour mate. Thanks for sharing your knowledge. Love that disc, it’s just what I need to strip thick painted concrete.
I have a 300 sf concrete basement floor with 3 layers of old, flaking paint topped off with carpet glue. Hurricane Ida entered my basement and it's time to remove all the above crud. What's your opinion of the recommended diamond cup for my job. I'll be doing it with a 4.5 inch grinder?
Thanks
A very useful video thanks mate. 👍🏻👍🏻👍🏻
Thanks, this was helpful.
GREAT VIDEO well explained thank you
Thank you, very helpful!
I honestly can’t thank you enough!!!
1:50 I have the same dust shroud as you, in both a 4 1/2 inch and 7/9 inch models.
I think they would greatly benefit from a larger exhaust fitting. The 1 1/4 inch I believe greatly reduces the amount of dust collected.
Watching this makes my hips hurt. But they hurt all of the time anyway. I am going to get me one of those dust shrouds though. Thanks Jodee.
Same here man. This was a rough few days!
Very helpful, thank you
Thanks for the video. how long did it take to do your garage floor
Great video
Does any carpet glue or liquid nail bind with blades at all or does everything powderizes?
What grit do you recommend for angle grinder to remove concrete sealant? Will a floor maintainer remove old sealant?
great video
dear sir , shall we use this process cleaning for my factory shopfloor which has more resin spillages , gelcoat deposits with 5 to 10mm height .
Were going to try your method tomorrow. We have a floor with peel and stick tile we have been trying to remove from a kitchen floor. We rented floor stripper with a blade that didn't work, we tried a blow torch, and we tried acetone. For three days we tried and barely got anywhere! The Peel & Stick Tile has a rubber backing that sticks to the floor!
That was exactly how I started as well. Pain thinner, acetone, mineral spirits, heat gun, torch, scraper and elbow grease... NOTHING would work! This worked like a charm and took just as long as all the other methods put together and they didn't even work! Good luck! Let me know how it turns out.
Excellent
Do you press down on the wheel? My disk doesn't seem to grind flat or maybe I'm just a n00b since this is my first time trying to angle grind my concrete
The previous owner of my home just painted on outdoor caulk on the pebble topped concrete driveway instead of putting it just in the crack, a grinder will remove all the rocks. I bought a steel brush wheel, do you know of a chemical that may loosen up the caulk?
The only good way I found to remove carpet glue from concrete. The solvents don't do a very good job. It's very dusty, but works
The way you grind that asbestos is awesome!
I would agree with you, but it isn’t asbestos. It’s just carpet crud and adhesive.
It does NOT look like asbestos to me.
Yea that definitely looks like asbestos mastic.
Thanks for sharing
Looks hella good! Can you do the same on a Concrete Porch outside? If you Pull up ugly Green Carpet Turf and it has years of old glue?
I'm using the big home Depot dimond brush and it works but not on heavy glue.
I need to do a three-car garage, removing old paint. Paint remover seems to be a much better option.
Thank you.
Thanks.
This be the best video on removing junk from concrete.
Hey Jodee, Great way to do this. I have a 90 year old garage that needs work but the adjacent photography studio is where I will use this. Two things I want to mention.
1. On the focus thing at the end, check your metering mode. You're probably set to matrix metering where the camera takes in the entire scene and focuses on the largest parts. If you switch to Spot metering it will focus where you place the cursor in the view finder. Drawback: It may change your exposure mode too if your set to Auto. Best thing to do is set to Matrix and Auto, shoot a single photo and note the settings. Then switch to Manual mode and set the metering to Spot, use the other setting from the still. Boom! in focus and properly exposed.
2. I see that we both use the same barber. My garage is not air conditioned so the sweat rolls off my head. Beanies or caps from a local cycling shop are made to wick away the sweat with are uber helpful when dealing with that much dust and the sweat too.
Another great video, keep up the good work!
Thank you, sir! I wish I could come trade grinding for learning. I was so bummed when I got the footage and found out it was focused on the bandsaw! I think you’re at least on the right path with what happened. It’s set to evaluative metering (Canon) and single-point AF, which I set in the center of the viewfinder. I’m also wondering if I bumped it with my hand and moved the focus point. It wouldn’t be the first time as this camera is a little small for my hands sometimes (only downfall so far). I usually use tracking for talking head stuff but I’m not sure why I didn’t. I will try this. Thanks a ton, my friend!
Meh, its only about 3,000 miles. I will ride my bicycle out to you. 🚴🏼💨 😜
Inspire Woodcraft THE INTENT WAS A SOFT FOCUS. LESS NEED FOR MAKEUP AND BOTOX.
This video is quite informative! Only critical thing is that respirator isn’t doing anything with your beard in the way. The rubber seal is completely useless with more than stubble on your face. Medical fit test 101. :)
Genius!
Howdy Bud. Welp with some high hopes, I tried your setup to grind off a layer of paint over fiberglass resin that one of the prior homeowners of our home nuttily installed over our front porch stairs. We've been chipping it off with a mallet and chisel which was slowly working. Bottom line was the get-up took it off but also took off some of the old red concrete on the stairs. Didn't seem to go as smoothly as your job! Darn it!
Great video. Thank you for posting. Have you, or have you seen people paint their garage floors by section? I have a lot of crap to move
I noticed you're not using the 2091 pads in your respirator, you've got the bigger filters, but It thought those were for painting, spray, etc. not dust?
How long does the diamond disk last before you need another one?
Cool that for the good information
The old owners of my home hired some crew to put in wall to wall stick-on laminate flooring. Now, in the summer, the glue is oozing up between the cracks. My question to you is, doesn't the glue eventually muck up the grinder wheel and clog the diamond blades?
I see no one answered your question. What I do with glue that is for lvt/lvp and/or pressure sensitive adhesive I put either sand or flour (I go more with flour since it's cheaper) and spread it evenly where I am going to remove glue. The flour prevents the glue from sticking on your cup wheel or scrafier and the floor. Also makes it easier to sweep up.
3 days!? 😭 how many per day?? Looks like I have a long job ahead.
Great advice. Thanks
Would suggest though for safety turn off grinder when you’re putting the clear cover back on.
It looked like he unplugged the grinder for that
I was just doing this with the same setup and was wishing for a less aggressive tool. Those grinders and disks remove a lot of material quickly! I want to flatten more accurately without removing too much material too quickly. I'd like someone to make a diamond velcro disk for my little random orbit sander that could more gently remove a thin layer of concrete. Ever seen anything like it?
The 4.5 works, but man that takes a loooong time. The buffer style swing machine is usually a no go. Well done, but I know that it was a hard slog. Ever decide to polish that floor, hmu.
4:50 Hard to keep it flat on the floor. I find that a heavier 7 inch Makita grinder easier as it just about balances itself.
If you are dust collecting concrete it is basically a MUST to have a cyclonic stage in your vacuum and a filter bag, too. Otherwise you are going to be very frustrated with suction loss.
AB_015 you are correct. Extremely difficult to keep level - which is absolutely necessary to get the job done. I am not getting acceptable results with the 4 inch grinder with diamond cup attachment. Regretfully, will rent the 7 inch from HD. Or perhaps buy one, then sell on craigslist
I just used bags in my shop vac instead of a filter and cyclonic stage. I was only removing thinset from plywood though
That is way more effective than the time I removed 600 square feet of linoleum glue with my belt sander. I wish I’d seen this video three years ago. 🤣
That sounds HORRIBLE! I’m glad you said you would have found it useful though because that means someone else will too! 👍🏻
What is this device name please. I want order from online
will one blade do the job for about 200 square feet? or can I expect to buy a few extra?
One did a large area for us! Disk was $40 at Home Depot.
👍
You need a “PCD cup wheel” for taking up membrane, been doing epoxy designer floors for years ... reg diamond cup wheels is time consuming
I have to remove 1/4" thick epoxy floor in my small bathroom. Can u elaborate on what I need, please!?
Katherine cummins 10-13 amp 4.5” grinder, shroud and vacuum for dust and “pcd” diamond blade
can you help me how to remove epoxy stain from my vynil?
thanks
Do you guys think this would work to remove paint from concrete block walls in my basement? I want to seal them with a concrete sealer thats why I want to remove it.
I had paint on the floor as well and it took it right up no problem. I eventually had the whole floor down to fresh concrete.
Where are you ? I would like to talk to you. I have a big project. I need great advice from like you.
Would this work if I want to clean my floors in my house to stain my concrete.
I can't say for certain because I don't know the exact situation, but this takes EVERYTHING off and exposes new concrete.

great video music could have been skipped.LOL
Ok
you figured out how to get a vac to fit on a makita !!!!
Looks like a universal dust shroud
Hi, kudos for the smart workshop rework and getting it done!
Still, I wonder if it would have been a better idea to go and rent a en.wikipedia.org/wiki/Concrete_grinder . My friends restored a large wooden floor with a rented machine - they could work standing up and quicker with a much larger diameter disc.
Well like I said (I think) in the video, this floor is so uneven that a larger diameter disk would have most likely floated over a lot of the smaller dips and pockets. Plus the larger disks can't get into the tight corners like a smaller disk can, so you end up having to go back and touch-up with the smaller disk anyway.
my wife likes the extra half inch too.
you need a better camera or microphone... only getting sound out of the left channel.
This might be a YT issue. It’s never had that problem before.
@@InspireWoodcraft odd I think it was only the beginning of the video...
I was so excited to read the title, but I don't have a grinder so this is useless to me
You can rent them
