The Firestone Public house Project done in 2012. Located at 1132 16th Street, Downtown Sacramento. was one of the most severely damaged floors that we have ever done. It was thickly covered with multiple glues, adhesives and thin sets. We had to do test holes in various locations just to see if the concrete underneath could be honed or polished. The original plan was to diamond hone the floor to a 200 grits level. after completion, the owner changed there mind and opted for a 1500 grit polish. we simply went over the 200 grits honed with 400, 800 and 1500 grits. this is not what we call one of our truly polished jobs, But we did managed to increase the gloss level without the need to add much extra cost to the project.
