- This video shows an economical way to grind down small areas in concrete. All it takes is time and effort!
Concrete basement floor is very wavy and is up and down almost two inches over a short span. Self levelling cement has fixed most of the low spots but there are a few localized high spots that should be ground down.

"welcome to my basement...." well alllrriiiiggghty then XP
One day I will update the basement progress! Not much has happened since this video.
Dealing with this now with an old house- you did an amazing job with dust containment!
Thanks! Concrete dust I've heard is extremely dangerous so I definitely didn't want to be breathing that in. The dust shroud probably worked well enough to not even use a mask but I wasn't going to take any chances.
Jealous!! I’m currently doing this and I don’t know of it’s my shop vac or the harbor freight dust shroud but it’s Not helping too much. 😶🌫️ what a mess!!
Wife: Whatcha doin' honey? Me: Watchin' BJ Nation.
She rushes in & shuts down my computer. I was like WTH???
@@DarkFlamage Lmao. Story of my life with initials BJ. I just added Nation onto the end because I spent about 10 seconds coming up with a RUclips name.
Thanks for your help.😊
No problem. Good luck with your project!
Good video. That's exactly what I need for my garage floor.
Good luck! It's slow work but you will get there.
Nice job. I was once at Lowe's and told one of the employees I was gonna grind concrete and he looked at me like I had two heads. But where do you go from here? You've done the heavy lifting: if you wanted to, could you sand with progressively higher diamond grit pads, and after buffing and sealing, make it shine?? I'm wondering if that's possible with terrazzo, instead of hiring an expensive crew with large professional slurry wet-grind equipment.
Thanks for the comment. I'm sorry for not replying sooner.
I got the same look in a Home Depot when I asked where the 'feather boards' are for a table saw. They don't stock them and never heard of them!
I suppose you could polish the floor for sure. I just needed it flat enough to put down a dricore subfloor. It worked really well and some of my other videos show the subfloor.
The subfloor helps level things out but if it is too uneven, certain areas would be 'spring' because the subfloor wasn't contacting the basement floor.
Tks for your use HERZO dust shroud!
It worked well. No complaints! Hopefully my next project with it isn't as big :)
I used a grinding wheel I bought at homedepot, it was a diamond blade, about 60dollars, but it cut through something like that in about 5 minutes.
Good to know.
do you have a 4in or a 7in grinder?
@@rowankeltizar5961 4". If I did this over again and knew how much I would ultimately be grinding, I would probably get something bigger.
@@billjonesnation thanks, that's kinda what figured. I do this professionally including thin-set removal so I went ahead and got a 7in grinder. I also got the dust separator, so thanks for that tip!
Nice job. Thanks for sharing.
Thanks for watching. I have done a lot more grinding since and I am still happy with the set up. Clearly it won't accomplish anything quickly, but I think it seems to be a reasonable method for smaller areas especially when you are doing the work yourself and have time.
Awsome job there. How much is it for this dust splitter system?
I think it was about $40 CAD for the attachment to go onto the angle grinder.
Just like woodworking.......sanding vs grinding. Same thing, making it smooth.
Yup! I think I prefer sawdust over concrete dust tho!
Good job and good video - I don't even need to do concrete - if I do though...
Thanks for watching!! I watch a lot of How To videos that I will probably never need the knowledge for... but you never know!
Would love to see you complete the whole basement!
Me too! I've started to pick up some momentum on this project and have set a goal to be finished in one year. I have finally finished levelling the floor and have 90% of the dricore installed. I have moved my rough in for the washroom as well. My next big task is a brand new staircase. I will have a video out soon of how I made out with the stringers as a first timer.
@@billjonesnation very cool! you are doing a great job! I plan to do similar to you soon. From Winnipeg!
I just tried this with the Herzo and my Milwaukee grinder and there was plenty of dust. I even had my hose running outside so I could keep the shop vac out of the house.
That't too bad. I must have got lucky with my grinder and Herzo going together. I could probably get away with no mask with how little dust I made. Did the brush part of the Herzo make good contact with the ground? I found if I ever angled the grinder and raised up a side it would create a ton of dust.
@@billjonesnation i think the issue was the plane of my diamond wheel was sitting above the plane of the perimeter brush bristles. So that left a gap for the dust. I moved the herzo down a bit-- that is to say away from the motor--so now the bristle shroud touches the floor before the blade and no more dust.
I have a large bump in the middle of my floor, it sticks up properly 2 inches, maybe more. Can I grind that down? Or is there a way to just break it up. BTW.. what kind of mask? R95?
I agree with weekend warrior. Your best bet is to remove it in chunks. I have had success doing something similar with a Bosch Hammer drill. I have a video on that in my channel and it may be right up your alley of what you need. The video shows what it can do to level concrete. It still is a dusty process though so I have a shop vac going beside where I am hammering.
Were can I get a straight edge like that? Nice job
Search for "Bon Straight Edge" on Amazon. I got an 8 ft and 6 ft one from there.
Would that angle grinder work on uneven jagged bumpy cement. I just finished using a diamabrush for paint now I am using a wire brush on my grinder for the paint in all the pot holes.
I personally would avoid uneven concrete because it will break the brush seal of the dust collection and send dust everyone. I'm sure it would cut through it just fine though.
hi I need to level out a basement floor but it looks like the corner where the concrete was originally poured is very high. I’d say it’s about 4-5 inches higher than the rest of the floor just in the one corner. Is grinding my best option or should I look into pouring self leveling concrete or both?
I'm not an expert. However, in your case I would use a jack hammer to remove that 5" on concrete. You can smooth out the flat later with patching concrete or self leveling cement.
You can't really use self leveling to fix your problem unless you want a dump truck load in your basement to fill up 5".
Good luck!
How often did you have to empty the dust cyclone 5 gallon bucket for that one spot?
None actually. The dust really compacts in the bucket and gets quite heavy. Maybe 3-4 inches of dust and bits in the bottom of the bucket for that spot.
Which bushing did you use to attach the herzo to the tacklife?
I can't remember. I seem to recall it taking a bit of time to make work but haven't played with it much in a couple years.
@@billjonesnation Thank you for responding. Happy Holidays.
Why not use a wet grinding system instead of dry ?
No reason really other than this is what I had at the time. If I had to grind a larger area, I would have invested in a bigger system. The grinding I did was fairly localized and I used self levelling cement to level most of it. The grinding was just for the really bad high spots so I didn't have to build up the self levelling cement too much.
So I have a solid concrete pour slab. I need to get it down an inch or inch and a half to stay within code when I put down trex. What do you recommend
I honestly have no idea. I am not a professional. That is a serious amount of concrete to remove. My method removes about 1/4" of concrete in a small area. I would maybe consider other options. Is there a thinner floor or subfloor you can use?
Can you pls tell me that Kind of grinder can do the same job as big floor grinder? Just it will take more time? I mean can I grind all floor in my house and it will be smooth and even? Or just small areas? Thanks
I think a big floor grinder will do a better job. They have a larger grinding wheel so it will be easier to flatten everything out. If it's a big job, it may be possible to hire someone locally that has a grinder and experience. They will have proper dust collection as well. The small grinder worked in my case because I was only attacking smaller / localized areas. The rest of my basement was levelled with self levelling cement. That being said, if you have a ton of time, it is probably possible to just use the small grinder. An entire basement of grinding may also burn out your grinder prematurely. Are you able to rent a larger grinder and get it done in a weekend?
@@billjonesnation No i move to 3rd world Country so i cant rent grinder and they dont have self leveling mixes - only doing still float with cement - but this starting to crack, so im looking any possible option :))) cas wanna do epoxy Floor and now we have raw cement pretty rough 🙈
But you can do with that kind a grinder you show - smooth smooth cement? Or it will have shapes of blade on it and it wont be Perfecty smooth?
@@rapnakaraibach6627 I think if you spend enough time on it you can get it perfectly smooth. I sometimes had a few lines in mine but it didn't matter because I put down a subfloor. This whole setup is fairly cheap and may be worthwhile testing out especially if you already have the grinder. The concrete diamond cup wheels are around 30$
@@billjonesnation 🙏🏽🙏🏽🙏🏽
I think this is what levels are for
What is your aluminum straight edge you're using?
Bon 24-121 3/4-Inch by 4-Inch by 8-Feet Reinforced Aluminum H-Screed with Plastic Cap. I bought it on Amazon for 65$ CAD. It is also great to use as a guide for cutting plywood with a circular saw or checking to make sure my framing is straight.
@@billjonesnation thanks for fast reply, cheers!!!
keep making videos
Thanks for this. I have lost motivation for the basement Reno right now but will be back at it soon. My next video will probably be me replacing the builder staircase with a new one I am building. Taught myself how to build stringers. Next is the install and treads and all that.
@@billjonesnation thank you sir
What makes it so uneven? Just poor craftsmanship?
