Hello
I Have Recently Removed Ceramic Tile From A Concrete Floor And Am Left With A Huge Mess Of Grout Absolutely Stuck To The Concrete. I Can No Longer Physically Scrape It... how Can I Remove It Without Damaging The Concrete Floor? I Want To Put Hardwood On It And Need The Surface To Be As Level As Possible.
Thanks
Marianne

I'm just throwing out words here, but how about a skim coating of cement to bring the floor up to the level of the grout instead of trying to take the grout off.
