Learn a Craft That’s Both Time-Honored and on the Cutting Edge of the Future

Concrete

Concrete is as a solid and strong a substance as there is — yet at the same time, it’s remarkably malleable, able to be shaped and used in many different ways. Working with concrete requires both enormous strength and the skill of an artisan.

From the Hoover Dam to the Roman Pantheon, concrete has been around for thousands of years. Today, it is the most widely used human-made material (measured by tonnage). It is the foundation of your home or office, it is used to make the sidewalks and roads that transport you, and it lends its strength and versatility to build dams and power plants to light your way.

Plaster

As durable as the ancient pyramids of Egypt, and as decorative as the Palace of Versailles, plaster provides long-lasting interior and exterior walls, it decorates our shopping malls and amusement parks, and it provides fire resistance and sturdiness in our offices and schools. It is even used for props and scenery on Hollywood sets.

OPCMIA members apply various plaster products in a wide range of settings. The use of the varied forms of this product in the wall and ceiling industry requires skilled workers who are trained to be artisans.
