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.
Aside from a uniform design with as little or as much aggregate exposed as the job requires, patterns and designs can be laid using contrasting colours. Unlike tiles, carpeting and other flooring materials, polished concrete floors are created on site.For this reason, you can't simply choose a colour or design you like and get a square metre quote. Estimates will vary, but generally expect to pay from around $50 to $75 per square metre.hile plain concrete can be polished, the results are rarely pleasing and what's generally called concrete polishing starts with the pouring of a special mixture of natural or coloured concrete and aggregate. The initial rough grinding is done to achieve a perfectly flat surface.
