Venetian Plaster

Architectural Stone employs traditional plastering techniques from the 15th century.
We deliver your most challenging demands in unique plastering finishes replicating the same plaster look as the great artisans of Italy.

Venetian plaster is NOT FAUX PAINTING….rather, it is a finish coat of the finest plaster, applied with a hawk and stainless steel trowels by skilled and certified plastering artisans.

The artisans at Architectural Stone Concepts will provide you with that special elegance and incredible beauty of Venetian Plastering. We have a huge variety of historically accurate and modern finishes for you to compliment most any architectural thyme.

Architectural Stone Concepts has the freedom to treat each commission as a work of art. The result is a true stone veneer plaster finish in a matte or lush translucent color of your choice.

The art begins with the source for the natural materials needed. The line of plasters we use result in a cool to the touch smooth or textured finish where you can feel and see the ingredients of natural Limestone and Carrara Marbel.

Lime and Marbel based plasters, once exposed to air, will carbonize, lose their causticity, and harden back to natural stone. Venetian Plaster, once applied, literally turns your wall into stone, providing you with that relaxing sense of permanence.

Carrara Marble

Each plaster is hand mixed and custom colored in-house at Architectural Stone Concepts with natural earth mineral pigments for ecologically sound applications.

Venetian plaster also guarantees against the formation of mold and bacteria because of the natural diffusion and control of humidity through the plaster.

To start, almost every finish we apply will begin with Firmonovo. Firmonovo is a bonding agent essential for a successful plaster finish. Firmonovo has excellent penetrating capacity into the substrate with an excellent binding/cohesive capacity while allowing the substrate to breath.

After the substrate has become a good base from which to work, we begin the finish layers of Venetian plaster. The first layer of plaster for many of our applications will be Prontomuro. Prontomuro is 100% lime plaster, modified with quartz sand, and becoming a base coat for the several layers of finish plaster to follow. From three to seven layers of finish are needed to achieve the true finish of Venetian Plaster.

The final step is a process known as self-burnishing. This happens when the stainless steel trowel, reacting with the marble dust and limestone in the plaster, seals and shines the finish. This also brings the trowel movements, of the previous layers, to the surface. Venetian plaster is traditionally, but not exclusively, burnished to a very high sheen. A wide variety of effects and colors can be achieved, from classical to contemporary. Unique and sophisticated color combinations are one of the trademarks of Venetian plaster, going far beyond any faux paint.

Venetian plaster was developed in Venice to replace the use of real marble, which was proving too heavy for the sinking city of Venice. The artisans of the 15th century had improved on the long history of using lime and marble powder for wall protection and decoration. The Romans learned the art of plastering from the Etruscans and Greeks of the 1st century BC but it was used mainly as stonewall protection and a base for wall fresco paints.

The Venetian artisans studied the plasters of the Romans and found ways to give it more breathability and resistance to the moisture and the saltiness typical of Venice.

It wasn’t until these Masters of Venice who had studied the plaster mixture based on lime and marble, that decorative plaster had found its highest point of beauty.

Architects and Interior Designers have come to rely on Venetian plaster applications as a must for their portfolios, and once you have seen and felt the many applications that are available, you will know why.
