<p class="MsoNormal"><b><span style="font-size:10.0pt">I
have a very large job consisting of 83 rooms of white carrara marble that has
40 year old non sanded grout, the job consists of restoration and re-grouting of
all marble in the guest rooms,  shower walls, 1 vanity, and the
floor.  1 room has been completed as a control sample and approved by
custy.  The wall grout was a issue, a hand grout tool was skipping over
the grout, we had to use our Fein tool to remove the wall grout which took more
time than I wanted.  Has anyone used a different tool or method for
removing stubborn non sanded grout?  </span></b></p>
