😊 as someone who does this a lot for a living this made me smile. Thank you. It’s a tuff learning curve.

A few other ideas-- 1) concrete grinder rental companies also rent HEPA filters to use with the grinder. They work much better than a shop vac. Helps get to near dustless grinding. 2). If you want to use your shop vac, add a hose to the discharge and route it outside. That way, anything that makes it thru the filter (which will plug up quickly) goes outside, and 3). if you want to use your shop vac, invest in a Dust Deputy cyclone. Then connect the grinder discharge to the cyclone, and the shop vac as well. Doing this, the majority of the material removed goes in to the bucket the cyclone is mounted on, and your vac filter doesn't plug up so much.

for thinset i recommend chipping with tile blade first not a chipping blade as this will get the floor much smother initially and u will greatly reduce the grind time wide thin blades for the chipping allow u to chip at a steep angle and the blade will bounce off the concrete but go through the thinset and leave only residual behind whatever is left only takes a few quick passes to grind for adhesives water is your friend first step is to use floor prep blades instead of sanding or finishing blades or a scarfire with water to bulk remove the glue dont need a lot of water but it fights the tackyness of the glue and keeps your blades from clogging up with glue when finish grinding the rest of the glue u want wet in front and dry behind the grinder this is the best way to fight retracking of the glue back onto the floor from the heat of grinding chemical removal of glue is a lot easier and faster however it voids most flooring warranties so be careful ive done acm removal commercially and residentially for 10 years now and have ground a lot of types of materials out of other materials there are a lot of tricks and grinding is literally the daily grind

Very good tips you give👍 I spray water with a garden pressure can, spray thin layers, minimizes dust and mess, pick up the waste with a scoop and bobs your uncle.

Very very good insightful tips. I simply used a 7" diamond cup for a rough spot in the remaining thinset on a small tiled area. Dust was insane! Came to your video to see if wetting down was smarter. I helped do a big floor at work with a walk behind grinder and with water and followed with shop vacs. Def a 2-3 person job.

Thank you for posting this.

Cheers thank you!

I would use a proper respirator. Grinding concrete produces silica dust which can cause lung cancer.

I use a hepa vacuum. No dust whatsoever.

Definitely use water I can only imagine the amount of silica dust you just caused 😂

What do you do for the glue? I have 3 living rooms that I need to take the glue off of.

Could have just used a leveling agent to go over it
