hi slb,
i would love to have an opportunity to quote to sand the floor and give you a head start on the up keep, but as you have only started the ncontract this is what you have to do,
clean the floor properly witha degreaser and then neutralize it. then apply johnsond liquid wax with a mop, leave to dry, then buff it with brown pad, you will need a box of five as they will get dirty, if required to get a more shine apply more and buff again, this system will need regular buffing to keep the shine on.
good luck, and if they wantb it sanding give us a bell.
thanx jonny
let castle take the hassle
