We approach the close of the year, a time of repose,
reflection. My thoughts have drifted towards the many friends I have made
across the country and the globe due to my curious profession. Plaster is an
ancient, noble craft, virtually unchanged, whose practitioners form part of a
continuity of human culture as old as civilization itself. Personally, I must attest
to the fact that I have been the beneficiary of a wealth of knowledge from many
generous colleagues. What is there to do then? For myself there is a resolution
for 2013: Share, Teach, Diffuse traditional plaster trade knowledge.
State of the Art
I have to ask myself, why do I feel impelled to make such
a commitment? The simple answer: there is a need. We have to be honest. The
plaster trade is far from its zenith. The guilds, academies and unions that traditionally
shouldered the responsibility of passing on trade knowledge have collapsed or
are severely diminished. The atelier system of master, journeyman and
apprentice in place for centuries has been replaced by a typically divided corporate
structure of management and labor.
Yet, as my grandmother used to say, “if it’s not dead don’t
bury it”. Actually, plaster is far from dead. There is a renewed appetite to
learn the trade by artisans, to specify plaster by architects, to live in
plastered homes by everyday people. The restoration, preservation movement in
the US and EU began to gain momentum in the mid-20th century. Loads
of painters and artists have taken up decorative veneer plasters, particularly Venetian
plaster and marmorino in the past 20 years. Natural builders are going back to
basics plastering rammed earth, cob plasters and straw bale homes inside and
out.
What Is There to Learn?
Materials. There are a number of modern materials and
systems that have supplanted traditional plastering: EIFS, drywall, Portland cement
stucco to name a few. No need for my support there. I’m more interested in what
we’ve been using for plaster for the previous 12,000+ years: clay, gypsum and limes.
Studying their individual chemistry, physical properties, interaction with each
other, compatibility with various building assemblies and highest and best use
in diverse climates goes a long way in understanding the traditions surrounding
them.
Traditions. In plaster these are as diverse as humankind.
I could not pretend to achieve expertise in them all. Nevertheless, there are two
basic categories that all plastering can be classified under. Primarily plaster
is used as a coating or render. Traditional plaster is used as a coating over a
solid substrate or a lath typically to protect and finish the structural
supports of a building. However, plaster also can be modeled. Running cornices,
coves and other profiles in place or on a bench as well as casting ornament,
modeling or carving in situ explores an entirely different art in which plaster
excels like no other medium.
How to Share?
Those who know me also know that I believe in sharing plaster
knowledge openly. My figurative door is always open to discuss any technical or
artistic inquiry. If I know a best practice or can direct someone to reliable
information I will share it, freely. There are three ways to learn plaster best
practices. 1) Read technical information. 2) Study well done examples of
plasterwork. 3) Plaster yourself. By far the best of these is the latter, the
physical act of plastering. I am focusing my efforts this year on how I can
share, physically.
I have been working with talented, experienced colleagues to
organize hands-on plaster workshops. French, Italian and Moroccan coating traditions
are scheduled for January in association with Prima Terra Plasters (http://www.primaterraplasters.com/).
A workshop teaching running and casting of plaster is being organized at the
same facility for later in the year. Two onsite consultations are similarly
being organized to help individual artisans set up their own studio for running
and casting plaster.
Plaster is a trade with a rich history and has given me a
lot. I’m always enjoying learning more, meeting more people. Hopefully, we’ll
have a chance to roll up our sleeves together in 2013. Until then, Happy
Holidays everyone!!

Do you have suggestions for help as we begin an Academy of Building Conservation in Darby Borough (just outside Philadelphia)regarding people who can teach flatwork?

Hello John,
DeleteA couple of craftsmen come to mind. Rob Wozniak is rather local, being situated in Easton. http://www.preservationworks.us/Home.html
Ben Scott is from the UK, brought up in a traditional program there, now living in Toronto. http://www.naturallimeplaster.ca/
Thank you for a wonderful post! The artisan traditions that created beautiful building should br cherished and preserved! The General Society of Mechanics and Tradesmen in NYC promotes these traditions through the Mechanics Institute and the Artisan Lecture Series. On March 12 Foster Reeve, an architectural and ornamental plaster artisan, will give a lecture that is open to the public: http://www.generalsociety.org/images/stories/pdffiles/general_society_2012-2013_lecture_series_schedule-letter_size-updated.pdf Hope you can be there!
