Our Hands-On Venetian Plaster Workshop provides practical, in-depth training in the application of traditional lime-based Venetian plasters. Designed for both beginners and professionals with previous plastering experience, the course combines essential technical knowledge with extensive hands-on practice.
Participants begin by understanding the lime cycle and the characteristics of different lime-based finishes, learning how grain size, application technique and polishing affect the final appearance of the surface.
The workshop covers the main types of Venetian Marmorino, as well as Grassello and Lime Paint:
Throughout the course, participants practise the complete Venetian plaster application process, from tool substrate preparation to the finished surface. Training includes how to prepare tools, assess different substrates, select the correct primer, apply each plaster using the correct trowel techniques and choose the most suitable protective treatment according to the requirements of the project.
Practice takes place on both vertical sample boards and full-size wall areas, including inside and outside corners, giving participants experience with the situations commonly encountered on real job sites.
Each participant will also produce several 2 × 2 ft sample boards, ¼ in thick, which can be taken home at the end of the workshop.
Particular attention is given to job-site evaluation and substrate preparation, helping participants understand how to identify potential problems before application and prepare the surface correctly for a durable, successful Venetian plaster finish.
Upon successful completion of the workshop, participants will receive certification in the products covered during the course from Stucco Italiano and Gulf Coast Plaster Artisans.

Gulf Coast Plaster Artisans was formed in 2022 as a natural extension of its sister business, Sylvia T Designs. The latter has been delivering plaster and decorative finishes as the Gulf South’s premier decorative arts firm for over 30 years. With our deep experience in application, we have used numerous materials over the years. Before becoming US distributor for Stucco Italiano, we began using their artisan level products on our own project sites with great success – loved by both our professional application team and clients alike. Our long-running track record as high-level plaster applicators allows us to provide top-flight customer service, education, and technical support to our clients. We proudly offer Stucco Italiano to artisans in the US and serve as their certified US trainer, hosting hands-on, certification workshops at our shop in New Orleans and points beyond.

Sylvia Thompson-Dias, owner, founder, and master artisan of Sylvia T Designs and Gulf Coast Plaster Artisans, has been in the plaster and decorative arts game for over 30 years. After achieving her degree in architecture from Louisiana State University, she jumped into the worlds of fine and decorative art in the New Orleans area. Though plaster has been used in this part of the world for generations, real lime plaster was becoming scarce. The scene had become dominated by acrylic and gypsum plasters. She became fascinated with true artisan lime plaster and picked up its mantle in 2017. She never looked back. After discovering Stucco Italiano, Sylvia trained with their founder and master artisan, Giovanni Polistena, in both Italy and New Orleans. Today, Sylvia has led both Sylvia T Designs and Gulf Coast Plaster Artisans to new heights and is widely seen as the region’s preeminent decorative and functional plaster artisan and is also a world-class instructor.
