Garage Floor Prep - CONCRETE GRINDING DIY using the Pioneer Eclipse rental from Home Depot

[@dondunning1307]

Wow, this is the best video I have seen on this tool. Two years ago I did this to a 2000 square foot house (3 full weekends of 10+ hour days grinding).... there was not a lot out there on this tool other then HD and factory stuff. You did a great job and showed the realities of using this machine. I have to think you have used a buffer before.. the learning curve to handle the machine was a little harder for me. Do not do the water method that he mentions.... I did that in one hallway and it created an insane mess. I do suggest running a light mop ahead of this to keep some of the dust down. Do not go crazy with water! A light mop only.

[@HelpMeDIY]

+Don Dunning thanks! And no, I’ve actually never used a buffer either 😬

[@watahyahknow]

small tip i learned from running a floorbuffer (basicly the same machine) put the extention cord over youre shoulder and make sure you move away from where the extention cord is comming from (allways pull on it , never let the machine move toward it , if it catches under the scrubber it will tear the cord a part

[@HelpMeDIY]

+watahyahknow good tip, thanks!

[@brianalexander4139]

Great video! I rented the same concrete grinder and grinded down the floor. The grinder has a pretty good amount of power so I agree with starting in the middle of the floor to learn how to use it. My pattern was to slide it left to right, right to left, and the vertical ovals. Lots of dust and swept throughout the process and after finishing. Then used a shopvac to collect the remaining dust. Pressure washed the floor to clean all dust. Don't forget to get a good respirator, safety glasses, and coveralls so you don't get your clothes super dirty. Now I'm ready for cleaning & degreasing, if needed, and then etching.

[@HelpMeDIY]

+Brian Alexander thanks! 🍻

[@73amx63]

Home Depot folk gave you good information. The thing is a beast. Best to let it find its own plane or its own comfortable operating position. It can turn easily. I wanted to remove paint overspray so bought a red pad and some 60 grit paper. Worked well

[@HelpMeDIY]

+73 AMX yes! 🍻

[@trailjockeytj6160]

To get more power out of that unit, you had an interesting technique that works limited. It’s better to lower the handle and put it into your hip while twisting the handlebars, pulling up on your left and pushing down on your right, it will get the right hand of the machine cutting like what you’re doing with the backside of the machine but continuously, you just have to lean into the machine, and that gives more weight on the cutting surface, or at least makes the cutting surface smaller, giving you more weight on that section. I am a professional flooring, guy, and polish floors, quite a bit the first house of a garage like that would take about an hour with our machine, 25 hp grinder with a 7 hp vacuum all 480 V three phase. And finally your shot back will handle all that dust on your final cleanup. It’s just you would have to shut down and clean the filter quite a bit which is a safer way as far as breathing hazardous dust but you did have your respirator on so then you just have to worry about the best going where you don’t want it like into the rafters and so forth

[@HelpMeDIY]

+@trailjockeytj6160 makes sense

[@linabracey3177]

Yes that’s what I did.., 15yrs ago of course. When women do things we gotta be more creative so the weight pushing even though I’ve always been slender worked for me. I was prego too back then. Doing this project again years later for a basement floor and taking all the tips I can get. Taking notes 👍👍 thank you for the input.

For anyone doing this, I’d recommend getting the premium “fine dust” filter as well as the adding the collection bag that you can put inside the canister. I do this for woodworking and general maker stuff. For a few extra bucks, your shop vac won’t even know it’s within inches of dying.💨

[@HelpMeDIY]

+Brady Barrera I agree, assuming they have it available 😁

[@ledi2005]

Yes, a collection bag saved me while skimming walls. No dust at all and it saves the motor too. Best investment ever.

[@akhere07]

Is that not included with rental?

[@linabracey3177]

Omg. Did this grinder when I was prego years ago. Ya the machine does have a mind of its own. But not impossible to control. I’m a slender woman.., so anyone can do this. You do change a lot of the sanding pads and it’s not difficult to change- at least the model I used. Definitely shop vacuuming and then I use the flat bona mops. Picks up more than other styles. New project now, great refresher good video. 👍👍

[@HelpMeDIY]

+@linabracey3177 thanks! 🍻

[@A6Legit]

Pro tip, the lower you keep the handle bars when running the easier it is to keep it steady and get it to go left and right when you lift the handle up or down.

[@HelpMeDIY]

+@A6Legit yep, thanks!

[@screwdriver7507]

The right tool for this job is the 10” concrete grinder that Home Depot rents. It’s a very heavy machine, almost 200 lbs, so getting it home can be a chore. I had to rent a small garden trailer that had a ramp/tailgate. But getting it home was definitely worth it! At least 2X more effective as the floor buffer setup. Also it was MUCH easier to control.

[@HelpMeDIY]

+ScrewDriver750 sounds so much better… this was all my HD had

Am I supposed to put a disc on it? Or use what’s on the machine

I just rented this, I agree its the better tool for the job (or so it seems from my research) However, I didnt realize how heavy it was. I am picking it up later today and only have an SUV. Wish me luck otherwise will need to reschedule and figure out plan B hah

[@ottomc560]

Did you use the grinder pad that came with it??

[@francoisparadis5184]

Next time use "dustbane"...I think it's "sweepy" or something here at Home Depot. (very small wood chips with an oil...You put it down and the oily chips pick up the dust as you sweep, so nothing comes up. It also works for drywall dust....It's simply amazing. You would not even need a bag of it for your project a little picks up a lot of dust.

I have a question, I am converting my garage to a living unit...my footings around the garage are sticking up about 6 inches just like your stem walls... do you fur out the stem walls and install the drywall half an inch above the stem wall and just do a really high baseboard? Or do you fur out the wall and install the drywall all the way down to 1/2 in above the concrete floor? But the stem wall/footings will be behind it?

[@trailjockeytj6160]

Also, a better way to scuff the surface is a shot blast. I thought you were going to try to polish this floor which is what we do when we grind. We will use eight different grades of grinding pucks Starting at 18 ending at 800. A really good look for a garage but way too much work for 110 V. If it took you 10 hours to do the first grind, which wasn’t sufficient For an initial grind for polish, by the way, you would’ve been there for weeks! Painting a floor to me, is not the way to go, I assume you’ll end up getting stains from your tires sitting on the coating, and hopefully you got enough prep to keep your hot tire from just peeling off the coating after that tire cools and backs back out of the garage. But you did go pretty far to get a good profile. I’d be curious to see what the grip of your grinding disc was.

[@HelpMeDIY]

+@trailjockeytj6160 I didn’t use paint, the coating I used is marine grade and has been perfect for tires, chemical spills, etc. extremely durable and easy to clean.

[@ssdtrain1]

When done grinding, vacuum floor check vacuum filter every 5-10 minutes. empty then repeat process. Wet mop, (not moist mop) with a large head (not a kitchen swiffer mop) but a commercial size and bucket from Home D. to pick up the rest of the surface dust from the concrete. Don't scrub the mop, go back and forth turning the mop on your return swipe, "scrubbing" works the dust back into the floor. And try not to pressure wash unless oil stains are present.. Have fun !!

This is a new pour, cured 30 days, right? If so, use a floor maintainer/polisher RS16 with a 60 grit sanding screen underlaid by a black pad as a backer pad. All of this is at home Depot Tool Rental. This technique produces a better surface for coatings or sealing without curricular grind marks Vacuum up the grind dust grind and microfiber mop with zep NEUTRAL cleaner, 2 times. Rinse thoroughly. Let dry overnight with fans. Coatings cannot be applied on moist floors. Will fail later. Concrete us porous and permeable. Concrete should be coated only when moisture is 10% or less. Get all moisture meter at harbor freight ($10). This saves time, money, and produces a better surface with open pores. I know this from doing oodles of garage floors professionally for 14 years. Another option is call us to do high end diamond grinding with various iterative diamond tool segments for polished concrete, from coarse to fine. We use HEPA vacuums. One note: wet grinding is messy and the rinseate water will leave a mess all down the street! We use a hot tire resistant sealer. Hot tires WILL lift up most coatings and epoxies. GUARANTEED. Polish concrete that are densified and sealed properly---and sometimes stained first, are the most durable. All coatings fail eventually and you'll hv to grind it off. Geological engineer here, most contractors haven't a clue.

Anyway HD rents the EDCO grinder which seems like it will flatten everything out moreso than the machine in this video. However, how do you knock down high points? I was going to mark the high spots with a sharpie and then grind as needed. Will this work?

If you have only fine dust no rocks or debris a squeegee work’s beautiful if you do have rocks and debris from grinding lightly broom then squeegee

Would be faster and easier just to Shotblast the floor, just saying since I own a epoxy flooring company. Stan Houston rents them out for about 300 a day

[@HelpMeDIY]

+john doe I’m all for faster and easier!

[@maxromero7998]

Great video but rhat concrete is way to hard to cut that surface. Mine is not that hard troweled. Might just get a real concrete grind thanks for the video

[@HelpMeDIY]

+Max Romero thanks! 🍻

[@Imwright720]

That attachment is really the wrong one. It’s going to sand more than grind. Your really need to get a good GRIND WITH ABOUT A 40 GRIT scratch pattern for the best bond. Certainly anything is better than nothing but I would hate to work so hard and have the finish fail. Maybe the head is just worn out. It’s not how much you grind off but the scratches it creates that matters.

[@HelpMeDIY]

+Gene Miller well that’s the only one they rent. Maybe it’s worn like you said though.

[@charleslee4361]

I hate replying negative comments. So I wasn’t going to say anything. But you are the only comment that I read that is spot on. And yes I am a flooring guy.

[@Toofastfourluv]

A laser level to determine your effectiveness

[@HelpMeDIY]

+Dedra Skipworth perhaps. Although just visually seeing it scuffed up was all I needed to know that my paint would stick

[@JohnnyVoidMusic]

Thank the home depo video or the employee did not tell me how to steer this so it throw me 6 feet in to a wall and flipped over.

[@HelpMeDIY]

+Johnny void yikes! 😬

[@typhoonjenkins8330]

Just watched this. Decision made, I'm hiring the pro's to do mine. I'm too old and couldn't possibly do all that work, which sucks. It is what it is

[@HelpMeDIY]

+Typhoon Jenkins better to know before you get into it 😁👍

[@alexkomala]

Would you recommend doing this on a 2400 sq ft shop?

[@HelpMeDIY]

+Alex Komala I think it’s necessary and will give you the best final results, but I sure wouldn’t want to do it myself!

[@alexkomala]

@@HelpMeDIY thanks for the reply. Epoxy came in after 4 month back order now it’s too cold to lay. Time will tell what I end up having to do!

[@HelpMeDIY]

@@alexkomala yeah it’s crazy how hard it is to get paint/etc these days!

[@watchyourtonex6989]

That is 100% a adhesive scraper for getting old adhesive off of concrete it just scrapes the surface you will end up buying that thing if you try to grind concrete with it. Cuz it will take the entire blade to do anything and still wont grind

[@HelpMeDIY]

+watchyourTONE x it did what I needed it to do and I didn’t have to buy it so…

[@cgrobe21]

Looks like homedepot rented you one with a bent spindle...

[@catcall569]

After watching this video, I might pay to have this done…

+@frankvogel1403 good idea 👍 🍻

[@sunracer1869]

1: to 10 Acid & water ratio with the white scrub pad & push broom with a helper moving water & would have been much better. Advice from hom depot employees is like getting advice from kamala Harris.

+Capitan Mike 😂

[@diehardfan173]

Laugh out loud, as soon as he said the Home Depot People I was thinking…

[@VictorMorales-fh4br]

Proof that the captain is not always that smart

100% right. Never take advice from her, I mean them, or it.

"How can I bring politics into a comment about grinding concrete"

[@TheCureThatKillz]

Should have rented an actual concrete grinder instead of a floor sander with a diamond pad.

[@HelpMeDIY]

+TheCureThatKillz that is the correct machine.

[@TheCureThatKillz]

@@HelpMeDIY sorry man but it’s not the “correct machine”. I own a concrete coating company and have been in the industry for a very long time. If a floor sander was the correct machine, us professionals would much rather spend $1,500 on a few of those instead of $20K - 50K on actual concrete grinders. You’ll never see professional companies using those to grind concrete, at least you shouldn’t.

[@HelpMeDIY]

@@TheCureThatKillz well I’m sure there are bigger and better machines to do this, but I just meant that’s the one that Home Depot rents for this task. Thanks for clarifying

[@tylersGBO]

@@TheCureThatKillz so trying to smooth out rough concrete, better to use a grinder and appropriate pads for smoothness?

[@jiajia4856]

@@tylersGBO the machine in the video is the one you can rent from HD. You also need to rent the diamabrush from HD. I’m doing research myself. Planning my work on the garage in July.

[@jaromc9045]

thats not a grinder, its a floor machine. for sanding and buffing

I tray this with the sanding paper same machine, it was a nightmare, I could not controlled, waste of moneyed the effect is all ugly scratched, the best way is to give a wash finish the next day of the poor to the acid will also di the job, if you are doing to tile it it will be just fine

[@HelpMeDIY]

It works, just takes effort

[@edwardcrone2465]

Water

[@HelpMeDIY]

I talked about that

[@christianschuessler7318]

First need to know how to operate it without it bouncing like that. You just the handle of the machines in line with your hip and you basically drive the machine with no bounce and you simply controlled the left and right movement with pushing upper down on it at that level takes a little bit to understand, but it should be almost effortless

[@HelpMeDIY]

Yeah, I got the hand of it eventually

[@EdA-bz3bu]

5:40 🤣😂🤣😂. you are convincing me to have a pro do my garage floor with industrial epoxy. What are they about $6/sq. If I ever decide to coat the floor. Currently my garage floor has rough areas and cracking. *Please remember to wear the proper mask no matter how little you think you are inhaling. Silicosis. Your boss(wife) will kick your a$$ if she looks up the dangers. And I will be very sad that something will happen to you, after aaaaall the years I have known you (zero😂).

[@HelpMeDIY]

+Ed A that would be a very reasonable decision 😆
