- In this video I demonstrate the effectiveness of the shroud I built in part 1. I couldn't see any dust in the air during or after grinding which is awesome!

I wish I could give this multiple thumbs up!
Looks like 180mm Makita wet grinder. A few years ago I had to grind the top of a concrete balcony in preparation to recoat concrete. I used two machines both dry and using dust collection. One was a 130mm machine If I remember correctly supplied to me and the other a smaller 5 inch makita dry grinder with a dust shroud . Definitely the wet grinder is a better optio. From looking at your video, very impressive. Grinding vertical is no easy task. Great video.
Genius ! A+ sir!
Definitely the way to go. Thanks for sharing the info. I didn't see any dust whatsoever and that was a sideways (vertical) test run. On the floor, I would imagine, it has to work just as great 👍😀!
It does! Used it to clean up some thinset and level out a slab. No dust whatsoever!

show did you grind the corners flush to the wall?? wow.
Also I bet the water keeps the blade cool and it lasts much longer! This really is a fantastic remedy (as long as you don't get zapped).
haven't been zapped yet! but yes, plz be mindful of where your chord is folks :D
What is the model of the makita you have !?
Me regalas la cubierta guarda polvos d tu máquina cuando ya no la quieras??? Esta padre !!!
Good idea
This cool! I have not seen this blade type. What tpye of blade is that?! Thanks.
They call them 12 seg, its a diamond blade for soft concrete
Where can I buy this whole machine?
what makita tool is that?
I want to do the same thing to a angle grinder for dust control cutting tile. I know you can use a wet saw but sometimes it sucks to haul a huge wet saw for a few minor cuts. Is your tubbing attached to a pump in a bucket of water?
I have a garden hose hooked up to the valve on the grinder. Standard brass valve typically used for swamp coolers.
Great
So you made that or what?
Please show the clumps of MUD from all the wet dust!
Little dust thanks to water?
Can i spray water on the concrete to be sanded so as not to create too much dust, since my grinder is not water-based and does not have a cap to suck up the dust and also has a single speed of 11,000 rpm.
You can, but once the water is absorbed into the dust (which happens fast), you get dust.
Or... you can split the difference between the two ideas:
If you just spray water on the concrete, it will get absorbed quickly.
But, if you want to build a water streamer like here in this video, you'll have to spend the time to fabricate it.
Or, instead of _spraying_ water on the concrete, you could point a small water tube (like the one in this video) at the concrete (or low-flow a regular water hose). It's the same amount of water as the streamer, so it won't get absorbed quickly. When you're grinding concrete, you're usually grinding in one small area at a time, so you'd only have to move the water hose occasionally. This method is particularly easy when grinding horizontal surfaces (floors), and you'll just need to get a clip to clip the water hose above a vertical surface that you are grinding when grinding vertically surfaces.
Flip flops? Really!
Hey, it's my house! OSHA ain't showing up 😂
