Any project that requires grinding concrete

[SlowShooter]

What I hate: any project that involves grinding concrete.

I had to mount something to a poured-concrete wall, the wall had some uneven bumps on it so I used an angle-grinder with a concrete-grinding disc to knock-down the high spots so the item would mount flush to the wall.

Now, I have used an angle grinder to cut or grind steel, and I know the mess it makes. I've used a concrete cutting disc before to make a cut in concrete block, and that makes a mess.

But, using a grinding disc to grind the surface of concrete is a whole `nother league: that 8,000 RPM spinning-disc hits the surface of the concrete,pulverizes it, and slings it at great speed all over the place. It unleashes a room-filling thunderstorm of concrete dust that settles all over everthing and permeates every open space in the room. This was a workshop area where I had stored some tools, It will take me days to get all the dust cleaned-up off of everything

(I was wearing a respirator for the dust)

I have a slew of friends who are sculptors. They always pay me to help with their projects. I have seen, and will see quite alot of concrete with those folks.

Good you were wearing that mask. The dust for that stuff really isn't good for anything other than as concrete.

For the cleaning use something like the Shop Vac Pro. It has an extra filter just for fine dust like concrete, plaster, and drywall. I have seen people use "standard" wet/dry vacs that do not have the special filters. It spews half of what it is sucking up out the exhaust side.

Half a basketball on the head of your grinder! You won't be able to see but if you can do it by feel it works to keep the dust down. You can even cut a hole for the shop vac

It will Not take "Days" to get all the dust out. Even a few years from now you will move something and still find the dust.

Grinders is what gave me my Tinnitus dam Grinders

Recently had to grind some concrete floors inside a finished house. Almost zero dust.

Two words. Terrazzo floors.

Which I love and have even helped install. But there are ways to mitigate dust with concrete depending on your application. Those vacuum attatchments from the previous thread are a great way, or go wet, and use the vacuum wet. Then you will get zero dust but you better know what you are doing or your gonna make a mess.

I concur with OP. I also hate cutting or demoing stucco. Especially when its the first thing u do on a hot sweaty day so youre covered in that grit all day.

That is cool.

I ground down my floors about 3 years ago with a gas standing grinder. Still had to hit the edges with angle grinder. Rigged an industrial fan for suckage and my brother stood over with shop vac.

It was a Long two days, but dust was minimal.

Good mask worth every penny.
