log b â¡ ( x y ) = log b â¡ ( x y â 1 ) = log b â¡ ( x ) + log b â¡ ( y â 1 ) = log b â¡ ( x ) â log b â¡ ( y ) {\displaystyle \log _{b}{\bigg (}{\frac {x}{y}}{\bigg )}=\log _{b}(xy^{-1})=\log _{b}(x)+\log _{b}(y^{-1})=\log _{b}(x)-\log _{b}(y)}.
If you wanted an 800 grit polish, which is still very reflective, there arenât as many steps, so the price is decreased. Polished concrete, in general, can range anywhere from $2.00 per square foot to $7.00 per square foot. Glossy Floors, before giving an estimate, takes the time to examine the floor very carefully.
Polished Concrete Prices. Polished concrete pricing and cost per square metre for concrete polishing can range from as little as Â£20 to as much as Â£150 per metre square. Additionally polished concrete overlays with exotic aggregates could add further costs of Â£10 to Â£50 per metre.
