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.
Honed concrete will outlast a grind and seal finish and mechanically polished concrete lasts even longer. Concrete polishing starts at around $50-$75 per square metre for a grind and seal or honed finish on an existing concrete slab.If you want to have the slab poured and mechanically sealed, it will depend on several factors.f you have an existing concrete slab, you can have it polished to a smooth and stylish finish. If you're building or adding on, get quotes from concrete polishing services before you pour your slab and you will have even more stylish options to choose from.
