I work in a historic house museum that is beginning to show large cracks in
the plaster.  Some of these have developed due to settling, others, due to
poeople touching the walls ("look at the hole in the wall...").  Does any one
have any idea of a product that will help monitor the growth of these cracks.
 I once saw a product at the Octagon House in Washington, DC- they looked
like "bandaide" that attached to the wall and was calibrated.  Any other
ideas.  I thought it would also be a great way to educate our visitors about
historic preservation/restoration in a site like ours, so it does not bother
me to have something show.

You can email me at [log in to unmask]

Thanks for any ideas.
