Marmorino Venetian Plaster

If Authentic Plaster FX mentions  Venetian Plaster to a designer,architect or builder in Vancouver,  they all seem to  equate the term to old world wall finishes, I’m trying to change that. In fact I am trying to change the misnomer that venetian plaster is only used for interior wall finishes….simply not true!

What is true mind you, is that there is no better suited texture medium then Lime based Venetian Plaster for interior and exterior stucco finishing. Now I used the word “texture” but in the case I show you here, there is no texture….yet it is a Marmorino Venetian Plaster we used on this exterior.

Authentic Plaster FX used Venetian Plaster,in this example, a Marmorino Lime Putty,to create a mix of contemporary west coast with West Coast Salish and Japanese influenced architecture .

Most onlookers think that this exterior stucco is  polished and acid stained concrete,when I inform them that in fact it is a hand troweled  lime based Venetian Plaster…there eyes open wide! What further blows them away is the fact that this particular project is in fact an E.I.F.S  wall system….4 inches thick  to be exact,using  STO’S Gold Guard rainscreen technology.

Architects, Designers….think outside the box !

Carlos Scarpa did…..bringing back the technique, and re-popularizing the use  of Marmorino Lime Plaster in the 1950’s namely with the Olivetti showroom and the Castelvecchio Museum in Verona Italy.

Now what does the reference to Scarpa have to do with my little marmorino venetian plaster project here in Vancouver? Well not much really but it proves that  thinking  outside the box you can come up with some really impressive designs which I feel is what happened with this architect/home owner driven designed exterior.

They asked Authentic Plaster FX for a smooth hand troweled plaster finish,and I gave it to them …the walls have so much depth ,which as usual does not depict properly in these photos…you have to touch and feel it to appreciate its elegance.

Pozzolanic Hydraulic Lime

A type of lime that has been used in construction since ancient Roman times is now covered by an ASTM International standard. ASTM International Committee C07 on Lime has approved ASTM C1707, Specification for Pozzolanic Hydraulic Lime for Structural Purposes. The new standard is under the jurisdiction of Subcommittee C07.02 on Specifications and Guidelines.

Greening of Mortars with Pozzolans

Quote from ASTM.org

“Growing interest in sustainable building has created a strong interest in fly ash and other coal combustion products (CCPs). Emergence of agencies like the U.S. Green Building Council (USGBC) and the Coal Combustion Products Partnership (C2P2) of the USEPA has accelerated this trend. Their primary goal is sustainable development, focusing on environmental and social concerns. More than 30% of the 100 million tons of coal combustion products produced in the U.S. annually are being beneficially used in such things as manufactured stone, ceramic tile, shingles, concrete, aerated cellular concrete blocks, concrete blocks, stuccos, and mortars. The use of CCPs positively impacts the environment. Specifiers, contractors, and industry need to recognize that environmental stewardship today affects our children tomorrow. The features and benefits recognized in pozzolanic mortars reach beyond the technical, environmental, social, and sustainable aspects of this mortar. They signal future generations to track, improve, and develop mortars beyond any of our current technology”

Natural Hydraulic Lime (NHL) is seeing a worldwide comeback

Hydraulicity & Properties

Hydraulicity is the property of a binder to harden in contact with water.

Hydraulicity is produced by burning a limestone containing silica, alumina and iron oxides which above certain temperatures combine, totally or partially, with the Calcium Oxide. The resulting silicates, aluminates and ferrites give hydraulic properties to the product. Today as in the past, natural building limes are obtained by burning and slaking limestone and the more or less hydraulic character of the finished product is directly related to the percentage of calcium silicates, aluminates and ferrites formed during burning. The composition of the Earth crust shows the predominance of silica and its presence is almost inevitable in all limestone deposits.

Cement Stucco’s are Evil !

There I said it….but until the majority of home buyers and builders realize the benefits  of  hydraulic lime base coats and finishes we will be stuck with cement and acrylic stucco in North America…where time is money friends!

Evidence shows that lime has always been and will remain a practical, sustainable, healthier and greener  alternative to cement, worthy of far more widespread use across the building industry.

Until the  time the consumers realize these benefits, the ST. Astier NHL will remain relatively expensive,and cement will continue to be used as base coats for exterior stucco’s,which is a shame

Authentic Plaster FX from Vancouver BC. is working hard, exposing local builders to Natural  hydraulic lime  stucco’s, and venetian plaster finish coats such as Intonachino and Tadelakt. Discerning homeowners, architects and the exterior  envelope engineers will look closely at the beauty and functionality of Hydraulic Lime plaster exteriors.

Exterior Vancouver Tadelakt Plaster project complete!

Landscaping is almost complete, this private residence in West Vancouver BC has the best of the best in contemporary finishes including an exterior Lime Plaster Tadelakt finish …there is no other house like it in the lower mainland of British Columbia.

Ryan Chivers of Artesano in Boulder county  Colorado seems to think this  is the only, if not the biggest exterior ever done in north America with Tadelakt lime plaster …if you know of another  …drop me a line.

For  a smooth stucco finish there is no better finish then Tadelakt ,this Vancouver exterior Venetian Plaster, also incorporates a rain screen cavity system,usually associated with leaky condos here in Vancouver,but which became part of the BC building code approximately 2-3 years ago.
