Anthony, I think you might mean "plaster". *A masonry wall is made
of brick or CMU. *Many plaster walls were done on wood studs with
wood lath/metal lath/rock lath; many were also done on top of
brick, CMU, gypsolite block, terra cotta block. *The wood framed
walls should have studs, the others will not. *I would expect that
you should see studs with your stud sensor. *Make sure you are
following the directions completely.

If you still do not get a consistent indication of a stud, it is
time for the time honored method of probing the wall with a drill
bit. *If you do the drilling just at the top of the baseboard or
some other system, it will be fairly easy to fill the holes
without showing.

I bought this Stanley stud finder and trying to locate a stud on
an
old masonry wall. I did as the instructions said *....slide
slowly in
a horizontal position with the activation button depressed. I
did it
on a 8 foot wall and the red light with the sound kept going the
entire length of that wall. I did it vertically also...same
results.
Which brings to mind that it probably has a metal grid
installation as
they did in the old days. So how can I know if there is a stud
behind
such walls with this tool. It seems to work fine on some newer
walls
that have dry walls..but my problem is the masonry wall. Also,
that
grid might be nailed to thin laths, which is not a stud.

Thank you, I stand corrected...oops. I cannot do the baseboard method,
cause it has ceramic tiles...its the bathroom wall.
