Garage Floor Prep - CONCRETE GRINDING DIY using the Pioneer Eclipse rental from Home Depot
Вставка
- Опубліковано 19 сер 2021
- This video shows you how to prep a garage floor for a sealant such as epoxy or urethane. I rented the Pioneer Eclipse machine and the "Concrete Prep Tool", each part is a separate rental. Total cost was $170 for 24 hours. It was the same cost for 4 hours, so make sure to get it for 24 because you WILL need it!

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.
+Don Dunning thanks! And no, I’ve actually never used a buffer either 😬
Agreed. Was told to wet and became a nightmare. Do dry folks and work right to left
@@JRODD666 thanks for the info!
Was at Wicked Weed brewery in Asheville this past weekend, good pours there. This vid will help me and the wife as we're tasked with doing our 3 car garage later this this spring. I see some do's and don'ts from this so thanks for taking the time to post.
+@BalcomFamily you’re welcome! We like Wicked Weed too
The space is looking great!
+Jim McCarthy thanks! It should start picking up a lot more over the next couple weeks 😁
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
+73 AMX yes! 🍻
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.
+Brian Alexander thanks! 🍻
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.💨
+Brady Barrera I agree, assuming they have it available 😁
Yes, a collection bag saved me while skimming walls. No dust at all and it saves the motor too.
Best investment ever.
Thank you that helps me make my decision regarding doing this myself
+Jay you’re welcome! 🍻
Thank-you for this video!
+Thomas Hermann you’re welcome! 🍻
Helpful hint when using the orbital sander disk . Use playground sand to help cut into the concrete
+@shawnwalker-ir1qk interesting… first time I’ve heard that 🍻
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
+watahyahknow good tip, thanks!
Doing some concrete prep now and this video showed me what to expect with the buffer rental .
Good stuff
+Rick Monster636 good luck! 👍
Okay! You convinced me. I'm hiring someone. lol
+Shellie Sager hahaha very valid decision!
I just rented one of these babies thanks for posting this video
+Travis Lau you’re welcome. How did it go for you?
@@HelpMeDIY it went very well!
@@travislau808 that’s great!
Great Video! I think the main idea is to give the floor some "tooth" to let the other chemicals adhere to. I think that if you have CSP-2 ground quality that the concrete will be ready.
+RV Scootin thanks! 🍻
Good job bro, thanks for your video, now I can paint my garage... 🤩🍻😎
+@robertocarlosampuero7579 glad to help! 🍻
Thanks for sharing that!
+@budmanzoom4441 you bet! 🍻
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.
+@francoisparadis5184 interesting 🤔
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
+@trailjockeytj6160 makes sense
I just emailed the epoxy company that quoted me last year...no shot I'm taking this project on. Great video!.
+@Scott-nj9gq 😎😉
Great video. Did you have any issues keeping the floor straight? I want to do mine but am worried about creating waves in the floor.
+T-Shirt Dudes nope, not at all. Doesn’t remove enough material to affect that.
Great overview. Hasn't seen anyone with the same watch band before ///M
+Coderman 🍻///M
now that you're an expert, come do my shop! :P
+Shawn D you can’t afford me. Man…. That ranks right up there with roofing! 😭
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.
+ScrewDriver750 sounds so much better… this was all my HD had
Does that tool handle pitting as well?
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
Nice video & it has helped me to think I can do this to my garage. My apologies if people have already asked or if I missed it in the video. How much did Home Depot charge to rent the grinder out to you? I really appreciate your honesty of the use and trial & error with this. Thanks again.
+Dennis Griffith glad it helped! I probably mentioned it, but I don’t remember now. You can call a HD and ask though.
He said $170.
I am putting in a bathroom in an area of my basement that has a concrete floor with all kinds of bumps, old epoxy and a spot where the original oil tank for the heater resided. This was a great video and I am tiling the bathroom area where the reminding 200 sf will be cork with a heavy pad. So my question is does this get the floor to a point where I can lay thinset and tile over it? Or will I still need to use leveling cement which I may just do instead of grinding.
+John Talbot good question. Mine was already level, obviously, so I didn’t have to worry about that. I wouldn’t think this machine would be good at leveling
True diamond grinding will accomplish that. Unless the floor is insanely jacked up...Home Depot machines like the Dimabrush diamond head don't really hone down high spots.
@@HelpMeDIY it's terrible at leveling. A Scanmaskin or Edco with 18 to 30 grit segments and a HEPA vacuum will do that fast and perfect .
@@Pelavitafan I would think so too, but I wasn’t leveling anything
Very good tutorial. Thanks
+Dee P I appreciate that thanks! 🍻
wow, feeling like you on the horse back🤪🤪
+@justinjr1623 yea! 😂
What about removing the top inch or 2 to redo the surface? I ran out of time stamping and was thinking of using this to remove the top 1 to 2 inches and resurface it with a bonding agent. Thoughts?
+SR Kidd12 not with this tool! No no no. 😂 it would take you a week
You might as well go at it with a sledgehammer and repour the slab if you're looking for 1-2 inches down. Diamond grinding removes maybe a millimeter or two from the surface in a thorough pass.
@@dp981 good point. I realized that after I hit send. 😅
I agree, lower is way better control.
+mike randolph 👍
Probly should of had a little water on the ground because the blades glaze after a certain temp
Something doesn’t seem right with the same one I got from Home Depot. It’s very hard to stop the machine. The handles don’t have any tension so when I let go or let off a bit the machine doesn’t stop. Is that the same feeling you had or did yours stop when you let off the triggers?
+Dave Schinkel hmm not sure about that
I'm trying to remove old paint from my basement concrete floor that is chipping away due to a flooding. Do you know if this tool will remove all of the old paint from the floor?
+Andres Ruiz I think it should. You could call them to confirm
To anyone wondering this machine/method needs water or the diamond blades will heat up and glaze over. Understandably, he stated he couldn't use water due to a time constraint.
+Dallas Blaze yes, and thank you for actually listening 🍻
@@HelpMeDIY Cheers! Thank you for taking the time to help others, including myself.
So if there is no time constraints, would you do this differently?
So if your patching first and want to use dye in the end, is it better to patch with concrete, leveler, enamel…. What will show least after grinding.
+FortyOdd Years good question but I don’t know. Maybe someone else will chime in.
You're a hard worker, I would have grabbed two dudes from the Home Depot parking lot and paid them to do all that. Then I would have bought them that beer!
+@stevodakine1 😂🍻
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 !!
Great vid! Why not pressure wash the concrete after brooming? That would certainly help remove dust.
+@gtoddwilliams you definitely could… I explained that I had to paint a few hours later and wouldn’t have time for the water to dry, so that’s the only reason I didn’t.
Thanks. My question is does this machine create a smooth finish?
I don't want to put epoxy on. I just want to seal the concrete with a clear coat.
+@snivvelslurderagementai2560 should be good for that I would think 🤷♂️
Does a concrete grinder like this help grind down bumps or lips on existing concrete floor?
+Derek Hudgin if they weren’t too big it would
lower the handle below waste u will have more control c15 flooring contractor
+p num yes! I meant to mention that in the video… the lower the handle the more control I had. Thanks for pointing that out!
Good video.
Wear a filter or respirator suitable for concrete, to protect your lungs.
Silicosis is nasty stuff you don’t want it.
+Thom Bauer absolutely!
Can I wet the ground so the dust doesn't kick when I grind? Would it be better? like a whetstone?
+Lewis some people do, but I hear it can also make a big mess and be hard to clean up
@@HelpMeDIY Yea, I did some initial scrubbing and degreaser with a deck scrubber and its basically leaves a thick black sludge. You'd need a strong wet vacuum to get it all up. I have a squeegee and a okay shop vacuum though so it'll probably work out.
Will this machine grind any humps or high spots or is this just basically sanding the floor?
+John M not much. Mostly just roughs it up
they have a heavy duty grinder at Home Depot rental
Hello all.... ive been a Floor technician for 6 years now (strip and wax floors).. but recently ive been trying to find a career path that pays more..
Ive never realized how similar this machince is to the buffer i use. I feel like i could do this with my eyes closed, with one arm. LITERALLY!!!! Is it that really that similar to a floor buffer or is it much more intense? Could this be a could carrer for me to advance to? What would the job tilte be????
+@token6282 I’ve never used a buffer so 🤷♂️
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.
+@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.
Good job.. for better control it is easy when the arm control are lower thand you use. I work a lot with this kind of crinder. And we're easy ( one hand control ) when you take that lower. But anyway, good job
+@fabienpics thanks! 🍻
Question, your machine seems a little bit worn out, old, but would pressure washing + grinder work better?
+@okcool4128 some people here say yes and some say it makes more of a mess 🤷♂️
Hi. How much did you manage to take off the floor? Mm or cm
+80volwerine my only goal was to rough it up so paint would adhere to it
@@HelpMeDIY I would be interested to grind 30 mm or so. More than an inch. I wonder what could I get for that.
@@80volwerine not this 😆
Rule one for dust extraction never use a leaf blower because dust settles, rule number 2 never use a broom because once again it creates dust, use a foam squeegee instead. 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
Pouring water and sweeping the dust off is one economic and quicker way, than using vacuum cleaners
+भारतीय yes, as I said through, I didn’t have time to wait for it so dry
What is the name of that one you rented ? Thanks in advance
+Paige thought I put it in the video. Only one my HD rented. Sorry don’t remember without going back to look
Will this remove old paint on concrete?
It’s supposed to, but I obviously didn’t use it for that so I can’t confirm
So what your saying is to instead of etching to grind instead?
+@williamcardenasgarcia5932 just another option
Is there a way to get the corners?
+@PossessedbyPhoenix not with a circle, but that’s overkill
You really wanna put the handle lower. Pocket height and lean into it with your upper thigh. I did wood floors for a long time and have buffed football fields worth of floors.
+Vindie makes sense.
Would you recommend doing this on a 2400 sq ft shop?
+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!
@@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!
@@alexkomala yeah it’s crazy how hard it is to get paint/etc these days!
What are you grinding off? Paint?
+LA Geronimo no, just roughing up a new concrete surface so paint will adhere.
in the future just drop your handle closer to the floor and let the weight of the sander do the work you want it to float across the floor not wobble raising it forward will cause it to bite when needed
+mark levenson yes great tip thanks
Lower the handle to your belt line or slightly lower . It will make the job MUCH EASIER!
+@deboraharmstrong3011 yes I’ve heard, thanks! 🍻
To keep the wheel cool, you should keep the area wet. Thtas how we do it anywAY.
+Joe Spear yeah some people like that approach
Fan in the window, suck out the dust boss 👍
+@frankvogel1403 good idea 👍 🍻
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.
+Michael Oritz yes new pour.
So my tires temperature are what’s causing the paint to come up? My garage has one of those speckled floors that’s got some age to it, but since I’ve been using it more I noticed more bare floor coming through
@@MrSrt4dodgeneon most likely yes
@@MrSrt4dodgeneon yes coatings do that I use the GPD hot tire pickup sealer on top of the coating. If that is not done right away the entire floor has to be stripped grind it off start over... The best floors for a garage are concrete polished floors. You get the exposed concrete which is a thousand times more durable than any coating
Michael - can I ask a quick question? I want to put down New Age composite tiles, which interlock and float on the concrete garage floor. The spec says anything over 3/16" over 10' unevenness is a problem. My floor is 60 years old but the concrete is in good shape and has some valleys of around 3/16 over 4 or 5 feet. Hard to even tell. 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? Also, the dang thing weighs 150 lbs and I won't be able to get it out of my SUV by myself, so dumb as that sounds it's another problem. Many of my neighbors are old so I don't want to break their backs!
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
+john doe I’m all for faster and easier!
Problem: I think this is a concrete scraper not a grinder. It's good to remove paint and coatings on the concrete, but not good for remove the top layers of concrete 'crema' to expose the aggregate, which some applications require.
It’s their grinder attachment
I’m experiencing the same hours long struggle as “Help me DIY”. I’m now going to try the Home Depot 9” grinder (much heavier machine) vs the 17” concrete prep tool (mounted on a floor polisher) to finish the OTHER HALF of my garage floor. 🙄
@@screwdriver7507 let us know the comparison!
@@HelpMeDIY Will do.
@@screwdriver7507 how'd it go. I'm about to jump into this situation
how big is the garage?
+Andrew Williams around 17’ x 36’ if I remember correctly
@@HelpMeDIY Thanks. I am going to epoxy my garage. It's a new construction with smooth concrete so I know I need to rough it up. If you could have saved time but spent about 2x as much on a shot blaster, would you have done it? My garage is 780 sq. ft. and I am a little intimidated by the time it would take with a floor polisher/diamond wheel. Any thoughts? Just discovered your channel and really like it!
@@andrewwilliams9973 I appreciate it! Hmm… possibly. My limiting factor was time… I didn’t start planning early enough to have this done before moving in!
After watching this video, I might pay to have this done…
+Daniel Cobb I don’t blame you!
4 to 5000
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.
+Gene Miller well that’s the only one they rent. Maybe it’s worn like you said though.
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.
A laser level to determine your effectiveness
+Dedra Skipworth perhaps. Although just visually seeing it scuffed up was all I needed to know that my paint would stick
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
+Max Romero thanks! 🍻
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

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

In job corps someone would sit on it when we did the floors lol 😂.
You can work that with 1 hand 🖐
+j vandyne 😂 luckily it turned out great!
Should have rented an actual concrete grinder instead of a floor sander with a diamond pad.
+TheCureThatKillz that is the correct machine.
@@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.
@@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
@@TheCureThatKillz so trying to smooth out rough concrete, better to use a grinder and appropriate pads for smoothness?
@@tylerstanfield3501 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.
They gave u a dina brush lol
+Alvah B 🤷♂️
thats not a grinder, its a floor machine. for sanding and buffing
😂Hold it against your waist, not with your hands out. It will be much smoother running!
+Hatman1974 I did! Hence the bruising 😆
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
Yeah, I got the hand of it eventually
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 😂
Laugh out loud, as soon as he said the Home Depot People I was thinking…
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"
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
It works, just takes effort
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😂).
+Ed A that would be a very reasonable decision 😆
Well it is definitely not polishing like the machine I have worked on
+MrMechanicandy polishing? I’m not sure what you mean. It’s a grinder. I was trying to grind and make a rough surface, not polish for a smooth surface
lower your handle some your handle is too high you have to relax and let it ride across the surface doing good for a pilgrim lol
+mark levenson yes thanks! 🍻
Go get a different grinder that one sucks
Leave the handle loose floating way better.
+Rob probably right
Man you have to look video tutorials 😂😂😂
It’s not dust it’s silica
+Craftworker4Life fair enough
It doesn't seem like this was even a necessary process.
It was very necessary for the coating to stick and not peel!
This thing was a bitch to control when ai tried it
+Dave Schinkel 😂 yup
I found out mine was literally broken. The from home depot needs to be serviced now and the triggers weren't dropping when I let off them so the machine would not stop. Like how the hell do they rent shit that's broken like that. I have the maker of that machine already calling them, that store to make sure they fix the fucking thing so nobody gets hurt down the road
@@tddtv wow, glad they are getting it sorted. What a pain
This is not the proper tool to properly grind a prep a floor for epoxy or Poly coatings ,.. ..it does not create a true fresh surface , u need a weighted grinder with at least 80 Grit diamond pads ,..
Actually it worked perfectly for my coating.
Just a horrible machine. Buy a werkmaster from Canada.
+Glen Garbera 😂
Dimabrish recommends water. Blades overheat. Do your research. Also, w water you get a better cut.
Better grind with a wet grind. I've done over 700 slabs. That eliminates the dust. Home Depot has a wet floor maintainer with a reservoir tank.
+DOG NATIOUS I’ve heard that, but I’ve also heard people say it was a huge mess and wished they hadn’t.
If I'm doing a garage thats 10 years old and just need to get off the old carpet glue and prep for GPD hot tire do I need a grinder or can I use a maintainer with pearl, flap, sanding screen progression? I saw your other comment about the sanding screens but afraid they will get worn down in seconds on concrete.
All concrete slabs are uneven with high spots and low spots. Orbital grinder will hit the high spots and leave the low spots. No contractor in the world can create a perfectly even surface.
