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 costs about $200 a cubic meter for the concrete itself, plus another $80+ for laying, (which you need as well for the tiles!) plus between $40-$90 sqm for polishing.So it really depends on what type of tile you want, and if you compare it directly to the finish of polished concrete.olished concrete costs about $200 a cubic meter for the concrete itself, plus another $80+ for laying, (which you need as well for the tiles!) plus between $40-$90 sqm for polishing.
