Welcome to the New Minnesota Lath and Plaster Bureau 

Yes there have been a few changes: Office operations have been suspended and you can no longer pick up the phone and just give us a call. We remain however in an on-line presence. We will continue to work to bring you relevant industry information. If you have a simple question just shoot us an e-mail. If it is more than just simple, we will forward it on to someone that can help.

Since 1953 the Bureau has been recognized as an education and technical spokesman for the lath and plaster industry. It provides information to architects, the construction community and the public on a variety of matters relating to the plaster trades.

We hope that this web resource center is beneficial to you for the information that is presented on lath and plaster systems.
