Cultured Marble Manufacturing Class

Provides a technical overview to enable manufacturers to process cultured marble (and other materials) using Gruber Systems’ molds, materials, supplies and other equipment. This week-long course (Monday - Friday in Valencia, CA U.S.A.) focuses specifically on the manufacture of Cultured Marble, Cultured Granite, Cultured Onyx and Spray Granite Manufacturing.

Note: For students interested in Solid Surface Manufacturing and Fabrication, a similar beginning course if available.

The curriculum for the first week of classes includes:

Health and Fire Safety
General Chemistry Background
Raw Materials
Quality Control and Lab Test Methods

This class focuses on "hands-on" experience, so that you will gain immediate experience manufacturing cultured marble products:

Mold Preparation
Gelcoat Application, Repair and Finishing
Cultured Marble
Cultured Onyx
Cultured Granite
Spray Granite
Veining Techniques - a variety of beginning veining techniques are taught, but experienced technicians should take the two-day Advanced Veining Techniques course.

Who should take this course:
The training program is for people new to the industry, as well as for those who have had experience but want a refresher, or to expand their experience. Hundreds of manufacturing owners, general managers, production foremen, workers, and industry suppliers have completed the Gruber Systems Training Program since it began in 1976. Gruber’s training program emphasizes a “hands-on” approach to learning. We believe the best way to learn the proper, most up-to-date, proven methods of manufacturing is through carefully supervised practice under the watchful eye of an experienced instructor. During the program, the participants set up molds, mix, cast, and finish a variety of products, including all of the newest formulas and technology available. Detailed information is presented on every aspect of the process, including raw material control, gelcoat application, casting techniques, and mold maintenance and repair. In addition to cultured marble, focus will be given cultured onyx, spray granite, solid surface, and other applications. Participants will learn the proper formulations, casting techniques, as well as fabrication methods.
