- This is a basic tutorial on how to polish a concrete counter top. This done with a standard orbital sander and a hose. The concrete polishing pads are the cheap set that you can find on eBay or amazon for about $13 shipped. Be sure to stay updated by subscribing to my channel. I am working on a series from mold to counter top.

*Great **MyBest.Tools** item. Superior quality.*
you are awesome, just go ahead and get it done, love that, love how short and informative you keep the vid and the instruction, simple, clear and down to earth with humour, Montana man I salute you and I now feel totally capable to go polish my 5ft wide 90 step staircase and less likely to feel the need drink vodka before looking for a how to you tube vid, thank you :) Fiona.
Thanks bro I'm getting my countertops done and bought the same off Amazon.
I’m about to sand the landing slab for my brick oven. Thanks!!!
I'd recognize that mountain any day! Good channel, this video helped me on my own project... also in the same place in MT :)
I made a 1.5"x 27" x 67" solid countertop in a form upside-down using concrete from Z-counterforms, which says it does not need any rebar or fiberglass. The instructions say 48 to 72 hours cure covered in plastic. I let mine cure for 6 days. Then 2 days outside the mold on a flat table, good side up. Then I began wet sanding with 50 grit and 100 grit pads just like shown in the video. The next day the ends of the countertop curled up about 1/4" each side and the slab is no longer flat. Maybe I used too much water for the sanding process and this somehow caused it to curl, but I'm scouring the Internet to find the answer as to why this happened.
It dried too quickly on the edges.
You answered my main question about resurfacing my concrete countertop: just do it. I will indeed. Quick question about sealant: I'm a bread baker and use the countertop for kneeding. I there a sealant that is absolutely non-toxic - as in zero risk? Thank you!
I have that dewalt and I piped water into the dust collector. It works amazing
That’s cool! Would like to see how you did that.
Montana Made couple reducers to a hose bib. Just let it trickle. I’ll upload a vid and tag you.
Great video. Love the sales pitch btw lol
Dude! I look back on this video and cringe. It was my first TH-cam video and its loud and poorly cut..;) Even said my channel name wrong.
@@montanamade1114 Haha thought it turned out pretty well. If you're still making videos I'll subscribe to ya I have a welding project coming up and this helped me learn quite a bit about table top finishing
Still making a bunch of videos. Just moved and finally get setup again.
I have done a bit of naughty non wet Sander stuff... One of them is my 18v Makita... Not going to kill me but obviously I don't want it breaking so I block all dust extraction through the pad and use small amounts of wet and it has worked so far...
Exactly what I was looking for. Tanks. PS I am going to try the professional grade Lake Worth Beach city water. If it doesn't work I will order some of that professional grade Montana water from you.
THANK BRO VERY INFORMATIVE. WE WANT TO TASTE THAT WATER
Tx for illustrating
Thanks for the vid pal
Skip to 4:09 for the polishing.
Best comment ever...
Will this method also work on granite counter tops just as easily? All the best!
I like it bro. May have to put on some protective gear against electrocution but nevertheless it'll work for me. Cheers
Do you have any final pictures of it completed ?
Is that an orbital sander or a rotary polisher? Looks like the latter.
You didn’t mention any of the products you used to polish, and the pads in what sequence and how to know when to use what
Hi there. Your videos help me a lot. Do you have any recommendation how to clean my sander after wet sanding. Not the filter but the body of the machine. There is a residue of wet cement all over and in the wholes of the pad. Thank you in advance.
I waited till it all dried and was about to clean it off with a rag. Glad this old video was still helpful! First one I posted.
Looking at re doing our concrete counter top in the kitchen. Looking at this set of pads on Amazon , might have to try. What grits did you start and end with? Also what sealer you using?
Thanks for putting this together! I am wondering about your thoughts on polishing a rounded concrete edge. Did you use the sander or do you have to hand sand that? Currently doing research for pouring a concrete hearth.
What pad would you start with if you didn't want to reveal any aggregate? Thank you
400 or higher
It would help a lot to show what the counter top looks like at each stage. This lets people know if they are on track to having the same results when they make the attempt. It would also be nice to see the finished product once it is completely dry and then again with the clear coat. It's unsatisfying to watch the video all the way through only to not be shown the finished, dry counter top.
Agreed. This summer I am planning on doing just that. This was my very first TH-cam video and frankly it sucks.
I had some bumps from possible air bubbles. Will the 50 grit help even the surface?
Did you have to wait for the concrete to cure before polishing?
David Hanks you don’t have to wait for concrete to cure to polish it you can grind it and use abrasive bonds like he has in video within a day the actual reason concrete needs curing is in case you densify it and or put a sealer on if you going for an exposed aggregate you can start polishing within a day or 2 depending on drying conditions
Would you mind sharing how do I look up the sander pads on Amazon so i get the right ones?
I am tempted to put a resin finish on my concrete kitchen countertops because I just cannot keep them looking nice. Do you have any thoughts about how that might turn out?
How long should I let the concrete cure before polishing?
the sander is 5inch, but the polishing pads are 4inch right?
I ordered the sander i just need the part number for the pads. I need to finish my countertops.

@@montanamade1114 I see the dewalt you use is a 5 inch and the pads you referred to are 4 inch.Is the re a reason for that or is that just how they come?
Thanks Curt
That was how those came. At that time. I was totally using the 4" on the 5" orb. Worked out fine. The pads are pretty thick.
@@montanamade1114 Perfect thanks for the answer.
Thanks for sharing! Do you know if there are any special tools we can use to achieve a similar effect (revealing aggregates) on spherical concrete surfaces? Like if you would have to sand a bowling ball. Thanks again!
I would say it depends on the outcome you want to achieve. If you were sanding a bowling ball I would say you need a lathe...but it you are sanding a sphere that is for decoration I have free handed those with the pads above and they look great. Just take extra time as you work the project, step back and look at it, then sand some more. Very light pressure the whole time.
hey your obital sander is way to much rpms for tbose pads it says only use below 5000rpms that sander is 12000
True at full RPM. I bought that specific sander though because you can adjust it down into the range for using those pads. Its been a sweet sander!
do u know the model number id love to buy it
@@PaypalBank Look at the video man and you'll find out haha
Price of pads probably means it doesn't matter too much if you tare through them.
Also, electrical power tools and water don't mix, so be careful. Or, maybe go pneumatic.
I have the same set up as you. I am struggling with the drill shaking like crazy with any kind of speed in the drill. Have to run it extremely slow to not shake. Doesn’t matter what grit, they all shake. I’ve tried high pressure, low pressure. Very frustrating!!!
Don't use drill, use sander
Get a puematic wet sander hose not enough to cool the pad
How would you recommend to give the edges a soft rounded finish?
I think it makes a cool final product for sure. I have done both. If you do the rounded edges be carful because the polishing pads remove a ton of material in those locations really quickly.
Rounded edges is done at caulking the edges of the mold before pouring.
Just curious why not use 5" pads?
Clear coat ?
Will clear coat break if the polished concrete piece is left outside?
Is there any reason I couldn't do this for a basement floor? Hard to find contractor for that.
I dont see why not. You can rent the polishing machine. Usually takes a few guys though. One cleaning and one running the machine.
Can you sort the sanding pad used to cut the first and last?
hi! is it alright to use an angle grinder?
Can this method be used on floors as well?
Does this process produce a lot of dust?
Hi, great video thanks. What speeds are you using?
Did you vary the speed with different pads?
I turned the speed all the way up on the sander and throttled it with the trigger. That sander is very easy to adjust speed through the trigger. Just start on a spot and it will make sense. If you pour a slab maybe mix a little extra and make a practice slab. I have three other videos that show a little detail.
Your metals and resins up to 200 typically run at 3-4 rpm anything higher I set to the highest rpm so the resin will burn and polish better
Do you use any slurry to fill in holes in any ever?
I do. I have a big project I am working on currently and I will post the video for it...inclusive of slurry use. The video above was my first ever TH-cam video and I have better editing software and a nicer camera now.
Kate Sorbello no the slurry does not harden back to concrete
So you are using an "water" with an "electric" sander? I think an air orbital sander would be safer and you get them cheap that have a water hook-up.
It's not that serious lol..
The worst what will happen, you short the sander, you shock yourself and trip the main DB.
RIP earbud users
I let it completely cure before polishing.
I let it cure three days.
Thank you
hey Amazon also sells camera tripods!
Right! I bought one shortly after this project. I was my first offical TH-cam video so a lot about the whole thing has improved since;)
Do I polish before or after I seal? Thanks.
Before
Thanks so much. Pouring tomorrow!
That’s not an orbital sander. That is a straight 4000 RPM sander with speed adjustment
Thanks for showing us the pads you used. I have the same disc sander as you but my backer pad is 5" and I cannot for the life of me find a 5" pad set. How is it that you have a 4" backerpad?
My pad has a threaded rod and all the ones online don't, I am not sure what to do about that...
It worked perfectly without issue. Forces you to keep the of flat. Just go slow and easy. Good luck!!
Are you talking the backer pad provided with the set has the threaded rod?
The backer pad on my sander has a 1/4” threaded rod, the backer pads with the polishing kits have a 1/2” female end or something like it.
I used the existing 5" pad that came with the Dewalt sander. Then I took the 4"pad from Amazon and stuck er right to the 5".
Ah yes, that would do it! Thank you, sir!
Why are you using a disc sander I've done this for 15 years and never seen anyone use that I've always seen grinder's Makita etc
I’ve used both and prefer the disk sander. I like the speed and control over what a grinder provides. Just works better for me. When I use a grinder I tend to take to much material off.
isn't the sanders RPM too high? The pad producer recommends low RPM to avoid gouging etc. the sander is 3 times the speed.... RIGHT?
Looks great! What sealer did you use? I researched some sealers and found Omega and Cheng to work great...have you had the opportunity to use either one? Which sealer do you recommend?
What is the sander model? What do you recommend?
How long did you let the concrete cure before polishing?
I let it set for about 3 days. It was a fairly warm day (70) degrees. Plus I put a tarp over it the whole time to make sure the moisture evaporated at a consistent rate.
Depends on size of slab
Crit Wilson 7-10 days is recommended.thats the shortest time, the longer the better
Water and electricity do not mix. Please discuss
Mad Mac 66 there are machines that have a shroud for back splash
@@JuanRuiz-zf8dw Cool. Can you recommend a model
anyone get electrocuted using a regular orbital sander rather than a wet grinder that is intended to get wet?
Nothing works better than Washington water and I'll sell it to you at a real good discount price per bottle.
As long as its not from the Spokane river you have a deal!! ;)
Can you give me the item number for the pads?
Link to them in the description
What clearcoat do you use please.
Pineapple Top no clear cut final polish stage is shiny and smooth like a clear coat
Can u ship me some water ??
can you link to the pads you used?
You bet. I am working on redoing this video now. It will be a multi phase series. Uploaded the mold making last night. Link below for the pads. Like I said in the video the pad adapter was garbage. The backer flew right off of the thing the first time. The pads are great though.

How to Build a concrete countertop Series has been uploaded. Be sure to check it out. th-cam.com/video/A9ej1IPvd0s/w-d-xo.html
get on with it!!
What clear coat do you use?
I use Behr Wet Look. I buy it at Home Depot. Just make sure you get the interior food grade if you doing a kitchen counter top. I am working on re-doing this video with better video and detail.

Is the tiles replaced br this,i am thinking of using it in residential scheme. And what is the strength if used in place of tiles.
Not quite sure what you are asking.
Montana Made. I want to use concerte polishing in residential project in all the rooms, rather than using tiles so is it suggested?
I recommend it. It will make a mess if you are casting in place so have a buddy to run a wet shop vac and the hose while you run the sander. Be sure to cover areas in plastic drip cloth that you don’t want splatter on. Have y u had a chance to look at my other concrete videos as well? They are a little more detailed than this video.
Montana Made ok thanks.
