- Sharing tips for using a concrete grinder to smooth a concrete floor after removing tile with a rotary hammer. This is not a how to use a concrete grinder video. BUT it’s concrete grinder tips I wish I would have known before removing thinset on my concrete floors.

😊 as someone who does this a lot for a living this made me smile. Thank you. It’s a tuff learning curve.
Tough is an understatement. Hands down this has been one of the harder jobs on the house so far! I can't imagine doing this all the time. Any pro tips for all us rookies in the crowd?
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.
Great ideas! Thanks for sharing 😄
So I literally purchased an older edco floor grinder and I was going to pair it up with a shop vac rigid hepa approved one. The filter with the hepa approved baggies will that work good for me while I save up for a better vaccum. I could save up to buy the edco vortec vaccum but will take me weeks longer.
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.
Glad sharing my experience was helpful for you. It likely gonna be a mess either with or without water. I think it's picking which type of mess you prefer :)
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
Thank you for posting this.
Cheers thank you!
I would use a proper respirator. Grinding concrete produces silica dust which can cause lung cancer.
Thanks for sharing!
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.
Great question. One I'm trying to figure out myself. I have glue all over one of the bedrooms. Tried a chemical solution but it just make it even gummier. Had someone suggest wire brushing...
Some of the other Edco instructional videos show swapping to different bits. They specifically mention glues and adhesives so maybe look into that for those that are mid project.
I’ve seen thin set mortar scrubbed into glue which changed the consistency. Then when the grinding started the glue came up easier and didn’t jack up the grinding machine
Just barely wet the floor for 1 hour the glue will easily come up when you come back from lunch then you can grind right over it.
Could have just used a leveling agent to go over it
Too late for us, but possibly a solution for others in the same spot. Appreciate the idea!
