Pioneer Eclipse

Using a coating to protect a high traffic floor is nothing more then a band aid in  many cases because the coating eventually wears off...  and then you incur the expense of re-laying your coating.  Polishing the concrete itself eliminates a coating that can wear off.

When maintained, a polished concrete floor can maintain it's smooth finish for 10 years or more.
