Small 2X2 patch in my foundation that I need to sand down. Is there any way besides renting a floor sander?

We are putting down laminate and this patch is about 1/4in higher than the rest of the floor. I hate to rent a huge machine for such a small spot. Is there anything like a grinder or dremel type tool that I can use instead?Small 2X2 patch in my foundation that I need to sand down. Is there any way besides renting a floor sander?
You can use an angle grinder but it will make a ton of dust. I would recommend using a wide cold chisel and a hammer. Knock it down and if it's low and not perfect, skimcoat it with Ardex SPD or Feather Finish.


I have a chipper hammer at work so it's easy to recommend this.


Even if you don't get it all the way down, you can probably still float it and feather it out so it won't be noticeable.


Of course this all assumes you are talking about a concrete subfloor.Small 2X2 patch in my foundation that I need to sand down. Is there any way besides renting a floor sander?
use an angle grinder and diamond blade...but instead of grinding the whole thing , make kerfs and inch apart and as deep as you need them... take you hammer and chisel to knock down the kerfs...less dust this way...
Use a side grinder it can be rented from home depot for a few bucks and it will take less than an hour to do that small of an area.
Use a floor sander. Is this a basement slab? I'm sure it isn't a foundation.
I find a belt sander with heavy grit paper can do it.
If its 2'; x 2'; and concrete - chip it off with a bolster and hammer.





if its 2' x 2', add hardboard to the rest of the floor to bring it up level.





If it's timber a belt sander will shift it.
Any run of the mill hand sander will do, but will take some elbow grease.
A floor sander for 1/4'; high on 2X2 seems overkill. Rental places have grinders for much less. For better results, I would just buy a cheap angle grinder (the wheel is perpendicular to the shaft/body of the grinder) and get a couple of 1/4'; extreme grit grinding wheels for it. The, you can run the wheel back and forth and see what you are doing depth wise. In a pinch, use some water to assist in dissolving the top finish of the concrete, but be prepared to get a bit splashed if you do, and protect anything close that you don't want a concrete slurry coating on. After finishing, you still have the grinder for future use. They take all sorts of grinding wheels, and I have even used mine with a mini saw blade that usually goes with a craft type table saw, for other projects including smoothing off edges of drywall, cutting small pieces of wood for craft projects, notching wood, etc.


Cost would be about the same as renting, maybe a bit less.


Use a level to see if your grinding is getting you where you want.
