Great video, but a note on dust control. A shop vac isn’t adequate to pull dust from even a small hand grinder. You need either a pre separator or a pulsing filter cleaner. You also need to pull 25 cfm for every inch of wheel size, that means 175 cfm or greater for a 7” wheel. They make high cfm, small shop vac style vacuums with auto thumpers that pulse the filter. A bagger vacuum like you are using is even better since it separates, pulses, and bags the dust which limits your exposure. Rental places that rent grinders will also rent these vacuums, it’s important to get the right one or it will clog up very quickly and release dangerous levels of dust.
thank you so much for this. I bought the shroud at HD, put it on my rigid 7" grinder, had to use the spacers to keep the cup from melting the shroud, but then the bristles on the shroud would fold into the grinding surface. That tape skirt is the trick plus comparing how much your 7" removes makes me feel better about my grinder. Again. Thank you
I totally agree with you. They posted a diy video suggesting using citric acid and a brush to scrub and prep your garage. I tried this method and was a complete fail absolutely so mechanical bond what so ever. You have to diamond grind or better. If I saw this video I would have never done the citric acid. In fact that should not even be suggested. Still pissed about it.
John Charville leggari suggests if you don’t have a grinder that citric acid and a deck scrub brush is sufficient for a prep. I don’t know what your talking about with alkalinity and concrete.
Word of warning: make sure you have an industrial grade vacuum meant for dry applications. I just spent the weekend shotblasting using a shopvac and I was dumping shot and the shopvac couldn’t keep up with the dust.
@@SuperJpaez Sun Rental gave me a refund on the shot blaster and I ended up renting a floor grinder. Another important point: With the floor grinder, you need to make sure the grinding plates are for a course finish. You’ll need to have the rental guys check this before you rent the equipment.
This guy isn’t wrong at all. Do not think your shop vac will keep up. Not even a top of the line craftsmen bought from lowes will keep up. You gotta spend the extra money to rent the vac with the shit blaster. You’ll be in for an extremely dusty job if not.
You talked about how you find companies that will do the concrete for your team. What are common websites that you recommend to find subs for concrete prep? Thanks for the content!
Is there video that follows this one. you mention showing us the next step at 40:27 but Im having a hard time finding a follow up video... unless all of your installation videos are a follow up to this one! Thanks for so much detail on this and the patching video!
What about old garages that have been painted? Do you still go straight to the blaster? Also what about large putted areas? Fill them or will epoxy self level in those areas?
How heavy is the shop blaster? Can I use this on a bare concrete slab on outside of house that will be used as a "patio"? Not very smooth. Need to smooth out the slab as the concrete pourer did a P___ Poor job of leveling/smoothing the slab. Since I would not be using epoxy could I use power washer when finished? Or is this equipment not the right one to smooth out bare concrete?
I love watching your videos. We are in constant leaning stage. I have been doing floors for a couple decades, and I am still learning, lol. Nice part about cutting grove into the concrete at the door.
To those looking to under take this kind project please remember to use the proper personal protective equipment because doing this kind of work does pose associated health risks. Cement contains silica which typically effects lungs,
Best tip... If you are using a shot bead blaster, put a duct tape line (two layers on top of each other is imperative) down and the blaster will not penetrate through your tape. Perfeftly straight line!
Great video…quick question. I see the reason for the cut behind the garage door when the concrete runs flat to the outside. But on my floor, my garage raises up 1 inch after the garage door ( on the inside). Where do I stop the epoxy coating? Should I run it down the inch drop? Will the edge on the rise take the abuse of a car wheel running over it? Any advice would be appreciated. Thanks again for making these.
Hey I polish concrete for a living and we would never use a small grinder like the one you used, they’re pretty much useless in big jobs, I would recommend getting a big 30 in propane grinder and it’s just cuts down time by 100 times faster and cuts the concrete 100 times better too
This is for diy dude, most people don't and won't wana spend money on big equipment. I'm sure for commercial jobs it does work better. But this is for home owners that wana do it themselves, I work in propane also and it's to expensive for a home owner to rent or buy equipment that requires propane. Come on dude
Did you get an answer to your question ? I contacted sunbelt in my area for my 700sq ft job and they recommended I buy 2 bags of SS-390 Steel Shot 50# Bag 390 Grit.
Also, that machine you are using, the shot blaster, is an edger as well. You can take the magnet off of one side to get within about a quarter to a half inch of the wall, no grinding necessary and shot glass prep all the way to the edge. I used to sell those years ago hasn’t changed much. But they are very underpowered compared to something. That’s 220 V.
Shot blast is the way to go. I have wood used for control joints in my garage floor about one in a half inches wide, will that be a problem? Should I remove the wood and replace with concrete before attempting to start this project? Love the videos and the product guys. Keep the videos coming. 👍🏻
My local Sunbelt rents out that very shot blaster for FIVE HUNDRED per day, 500/d, 1000/wk, 2000/mo. The same rates as a mini-excavator! I get it, kind of. Both save you a lot of time.
Looking for the next video on this garage getting the epoxy? I can find others, but not this one with all the details covered in depth. Link, or title, plz?
You should differentiate the difference between the grind profile and the shot blast profile. You really skim over that. The profile of a shot last will give you a tooth, or a much more jagged edge to bond to meaning more surface area. Meaning more sticky. Well grind depending on. The grid used will not give you anywhere close to the profile of a shot blast. The other thing that is mentioned, but not defined removing the cream opens up the capillaries of the concrete to get penetration and better bond. Good video all in all but I think the shot blast for coatings is the way to go. Although you’d be there for a long time with that little 8 inch machine you were showing you really need a more powerful 220 V or even 443 phase to get that shot last done quickly.
Do you have a best tip to remove paint from a basement floor? I would like to remove and reapply something more industrial as previous home owner I think just used cheap stuff. Thanks!
Problem i had is that the floor i applied the epoxy was full of small pocket holes, etc... This floor in tue video is really flat and easy to work with. Do you have any videos which show epoxy prep, for example to a previously brushed concrete floor garage?
@@brandonavellano1836 fill the holes takes times but the same basis as painting just fill the holes grind em down depending on the holes maybe do a skim coat
so i want to make sure i understand correctly before i attempt prepping my basement floor for a metallic epoxy.. do i need to do all of the following?- walk behind grinder + floor sander + shot blaster? i feel like just doing the shot blaster would suffice but perhaps i am showing my inexperience here? I don’t want to cut corners so if all need done, that’s fine. i just want to be sure i’m not doing unnecessary repetitive work. Thanks!
Yes shot blaster would do the trick as he did mention it was there favorite to use.. he was simply just showing us all the other available options as opposed to the shot blaster but for edges you will need the angle grinder
I've got this closet that I ripped carpet out of and is now bare concrete. Would prep be similiar in a small indoor space with concrete that's had carpet glued down to it?
If you are doing a basement floor and you can’t get the floor cleaner down the stairs and the pressure washer is out of the question what’s the alternative. Just mop the whole floor or something else. Let me know. Thanks John
Curious, I have a new pad to my new garage bc I built a bigger one, but have a old 30 plus year old pad that I want to cover too. So what would you recommend to use on both of them? Was going to use a walk behind diamond grinder. Will that be okay and do a affective job on both pads? As well I have a few low and high points in it that I was going to try and level out, so how can one do that? Bc it seems if to do that we can’t grind the floor for prep in those areas.
So if Im doing an interior of a home and use the Shotblaster with vacuum and also follow-up with the auto scrubber, can I paint all the walls beforehand with out worries of them getting too dusty?
I am having my garage floor replaced this summer. It may be obvious, but I want to check with a pro: assuming I don't have a sealant applied with the concrete, will I need to do any prep before coating it, besides just letting the floor cure completely and then washing it well?
Hello! This would be dependent on your project. Feel free to reach out to our team regarding your project and our products 👉 support.leggari.com/hc/en-us/requests/new
Can you guys explain what you do for grinding the corners..? I am about to install kit 13 but I can't find any specific instruction or tips on the best way to get into the corner. Not the edges but the corners.
Hey Bud, so I used to have carpet in my basement, last year I ripped up the carpet and I used a floor buffer with a diamond blade and took all the carpet glue off the concrete, is this sufficient to now lay the epoxy a year later? It's just all bare concrete down there now, I have been trying to figure out what I'm going to put down there for flooring and now I've decided to go the epoxy route, not sure what else I need to do for prep tho, since I've already removed the carpet glue.
Could you use just a pressure washer or mop instead of the floor scrubber like the one in the video, if you don't have access to a floor scrubber (or don't want to pay money to rent one)?
If you do not have access to a floor scrubber, use whatever you can that will get your substrate the cleanest it can possibly be. As you can see in the video, a mop is used where the scrubber cannot reach. This simply means it might take more than one time to completely clean the floor with a mop or pressure washer and more time will be needed for the floor to dry.
We recommend doing whatever your can to create the cleanest floor profile possible for the best bond to the products you install. If you have the means to do the cleaning machine, that's great. If you can grind, sweep, and mop it so that there isn't any dust or debris left over, great! You can view our epoxy floor kits here! 👉 leggari.com/order-flooring/
the diamond tooling does come in different grit, depends on what you need to grind, some concrete is softer some harder....garage and basement floors in my opinion are the hardest most dense floors, but that shot blaster takes it right off with a great profile
If it's thin, usually under 8-10mil, problem with some glues or other coatings is that they are elastic, which takes the energy out of the shot. We usually recommend grinding for removal and shot blast whatever is remaining
Very nice video, I used the hand grinder but my poor skill creates lost of gouges some seem a bit deep. Would it be visible after applying epoxy coating using a roller?
Yes, before applying epoxy, you will want the substrate to be as level as possible. Unless you do a flood coat first, if the floor is not level, epoxy will settle in those low spots, possibly affecting the design and leaving and uneven surface. We recommend using patcher paste to fill those low spots. leggari.com/product/patcher-paste/
Also, you don’t run that machine backwards notice how it’s leaving all that shot. If you just go forward with it it won’t leave the shot on the floor that you have to end up picking up. Did anyone train you on that machine?
Grinder or shot blaster? Seems like the shot blaster is the way to go but 700+/day to rent in my area! I just want be sure i have a long lasting floor ...
Great video, but a note on dust control. A shop vac isn’t adequate to pull dust from even a small hand grinder. You need either a pre separator or a pulsing filter cleaner. You also need to pull 25 cfm for every inch of wheel size, that means 175 cfm or greater for a 7” wheel. They make high cfm, small shop vac style vacuums with auto thumpers that pulse the filter. A bagger vacuum like you are using is even better since it separates, pulses, and bags the dust which limits your exposure. Rental places that rent grinders will also rent these vacuums, it’s important to get the right one or it will clog up very quickly and release dangerous levels of dust.
Hella smart to make a “root pass” for the material to sit in to prevent delamn. Mad scientist action right there. Nice.
thank you so much for this. I bought the shroud at HD, put it on my rigid 7" grinder, had to use the spacers to keep the cup from melting the shroud, but then the bristles on the shroud would fold into the grinding surface. That tape skirt is the trick plus comparing how much your 7" removes makes me feel better about my grinder. Again. Thank you
Omg such a great idea. I’ll never do anything like that again without cutting that edge-groove! I’m so glad I came across this video! Great work gents
If you feel the need to do that, trust me, just leave them now.

@@MrCustomConcrete
PPC Concrete is hard, and it is often used in the above circumstances
Is it either/or for the grinder and shot blaster? Or do you use the shot blaster after the grinder?
Yes, either will work you would not need to do both! We recommend using a shot blaster over the grinder, because you get a better profile!
Great video. Will the shopblaster remove carpet glue and old paint?
If it's thin, usually under 8-10mil, problem with some glues or other coatings is that they are elastic, which takes the energy out of the shot. We usually recommend grinding for removal and shot blast whatever is remaining

Very nice video, I used the hand grinder but my poor skill creates lost of gouges some seem a bit deep. Would it be visible after applying epoxy coating using a roller?
Yes, rolling the epoxy will leave a more thin layer which will not fill. Better epoxy filler those low gauges areas or epoxy leveling.
Yes, before applying epoxy, you will want the substrate to be as level as possible. Unless you do a flood coat first, if the floor is not level, epoxy will settle in those low spots, possibly affecting the design and leaving and uneven surface. We recommend using patcher paste to fill those low spots.

Nice video. How do you grind in the corners? With my 5" diamond wheel I can't get completly in the corner.
In all honesty just do the best you can, you can get pretty tight with a 4 or 5” grinder but obviously you can’t get it all!
@@LeggariProducts thanks! That makes sense!
