The Sacramento Valley Bureau website, home to lath and plaster
content found nowhere else on the internet, has expanded and
joined a larger group of Bureaus and will become a member of the
Wall and Ceiling Bureau.
For almost 60 years Architects, Designers, General Contractors,
Plastering Contractors and homeowners received solid information
from the Executive Directors of the Sacramento Valley Bureau for
Lath & Plaster.
Starting January 1, 2013, the same solid information will be
available to everyone in Northern California as the Plaster
Information Center, the Northern California Plaster Institute,
Sacramento Valley Bureau for Lath & Plaster and the South Bay
Lath and Plaster Bureau and the Drywall Information Trust have
merged into the Wall and Ceiling Bureau. We have taken the best
of each of these respected organizations and distilled their
over 200 years of experience and expertise into a website that
defines both Drywall Technical Expertise and White Papers and
Lath and Plaster Specifications, Installation Procedures, Crack
Remediation Protocols, Best Practices, Standard Details, Guide
Specifications, Glossary, over 70 Different Exterior Stucco
Textures with in depth definitions of how to achieve the texture
If you thought the Sacramento Valley Bureau for Lath and
Plaster website was full of content. Wait until you see the Wall
and Ceiling Bureau website. Simply Amazing!
Introduction to Sacramento Valley Bureau for Lath and Plaster
This website is designed to be a companion to all the Plastering Industry
codes, specifications, manuals and other information available to the Building
and Design Communities, and to augment reference documents to produce
higher quality plaster specifications, and bid and building processes.
We hope to give a clearer picture of what it is that Architects are
designing, General Contractors are actually building, and what you can
expect to see during your inspections, pre-job conferences, and the
punch list process.
The proliferation of new additives, admixtures, sealants new wall
components, substrates, papers, laths and finishes can confuse even the
most astute practitioner. We think it will be helpful to provide
performance characteristics, and indicate what to look for during
inspections, how the ASTM Standards and UBC or CBC relate to each
component of specifications and what kind of performance you might
expect when you add or subtract individual components. This type of
knowledge will allow you the freedom to design plaster installations
with confidence, inspect with knowledge and apply plaster with best
practices gleaned from well over 100 years of experience in plastering
We’ve collected texture data from the last 60 years in the finish
section, and will continue to include antiquing, synthetic stucco
finishes, and information on patching, remediation and case studies of
failures and how to avoid them.
We’ve included Typical Details thanks to the Architectural Firm of SKW
Architects, especially Kelly Reynolds and Brian Wiese, with Digital
Photographs of the development of the detail in real life thanks to
Roger Henley Jr.
The History of The Sacramento Valley Bureau for Lath & Plaster
1954 the Sacramento Valley Bureau for Lath & Plaster was incorporated in
Sacramento, California as an organization to promote Lath & Plaster. The
first director was Khalil Bennett. Notable Directors during the next
fifty years were Clyde Bell, Tony Schiro and Floyd Gates. The current
director, Bruce Bell is Clyde Bell’s first son.
The Bureau’s goal and purpose is to educate the Architectural,
Inspection, and Building communities on the best uses and practices for
Portland Cement Plaster, Gypsum Plaster and Synthetic Plaster wall
To this end the Bureau:
Assists and consults on Plaster Details for planned building
Interprets the Building Codes and Standards that relate to
plaster for the International Conference of Building Officials
jurisdictions in Northern California
Diagnoses the cause of plaster failures, and consults in
Acts as an impartial trusted third party mediator and expert
witness in litigation issues
Promotes new products that raise the standards of quality for
Conducts free seminars to Architectural Firms on the proper
installation of Plaster
Conducts free inspection seminars to City and County Building
Consults with Home Builders on proper installation of all types
of Plaster applications
In 1965 Clyde Bell helped compile the Lathing, Furring and Plastering in
California Reference Specifications as Director for the California
Lathing and Plastering Contractors Association Inc. The pre-courser to
the Lathing and Plastering Systems Manual that went out of print in
1988. The book was to help define the minimum requirements for a
satisfactory plaster job.
Bruce Bell & grandson
I was eighteen years old and attending University of California Santa
Barbara as an English Major and had no clue what plaster was other than
that I should stay away from the lime pit behind the garage where I grew
In 1970 after an unspectacular stint as a college student I moved to
Sacramento to find my roots and get a job in a bank or as a teacher. I
ended up as a Hodcarrier working clean up on a condominium project at
4th & P in Sacramento, having been given the referral from Tony Schiro
(Director for the Bureau for Lath & Plaster) to go see Dutch Florin,
business agent for the Hodcarriers Local Union. Blisters, cramps,
hemorrhoids, a sore back and old guys who hated college punks were my
introduction to plastering. 34 years later I’m a journeyman plasterer,
the Executive Director for the Sacramento Valley Bureau for Lath &
Plaster and would like to acknowledge Cornelius Bell, my grandfather (a
plasterer whose trowel handle I used on every finish trowel while
plastering) and Khalil Bennett (The first Director for the Sacramento
Valley Bureau for Lath & Plaster and current President) and the
Plastering Industry for allowing me to make a living.
As the Director for the Bureau, I’ve tried to paint as clear a picture
of the process of plastering to The Building Community as I could.
Hopefully this website will be of some additional value.
Director, Sacramento Valley Bureau for Lath & Plaster
The Sacramento Valley Bureau for Lath and Plaster acknowledges the
efforts of Rich Scheuermann, Architect, Specification Writer and all
around good guy in the production of this webpage. He is a no nonsense,
(some even define him as hard headed) kind of guy with a short fuse for
folks with an agenda, a shorter fuse for bull, and an infinite capacity
to nurture those with fewer brain cells than he possesses . . . hence
his willingness to help the Bureau Director with this project.
The Architectural Community has a gem in Rich and the Plastering
Industry owes him a great debt in helping make clear what seems to be
constantly viewed unclearly.
