Decorative Plaster & Running Moulds

Decorative Plaster

Decorative plaster refers to the use of plaster in creating ornamental, textured, or aesthetic finishes on walls, ceilings, or other surfaces. It can be used both for functional purposes (such as protection) and purely for visual appeal. These plasters often incorporate intricate patterns or textures, and they are typically used in historical buildings, high-end interiors, or in modern designs that aim to create a classical or sophisticated feel.

Types of decorative plaster include:

Stucco: A durable plaster finish, often used on exterior surfaces, which can be molded into a variety of textures, from smooth to rough.

Venetian Plaster: A smooth, marble-like finish that is typically used for luxury interiors. It’s a multi-layered, polished finish that can give walls a reflective, rich appearance.

Tadelakt: A Moroccan technique that produces a smooth, glossy, and waterproof finish, often used in bathrooms or kitchens.

Running Moulds

Running moulds, also known as cornices, mouldings, or coving, are architectural features used to add detail and visual interest to the junctions of walls and ceilings. The term “running mould” refers to the continuous process of shaping these profiles, often using specialized equipment to form intricate and consistent patterns. These moulds can be made from various materials, including plaster, gypsum, polyurethane, or even wood.

Running moulds are typically created using the following methods:

1. Plaster Moulding: Traditional plaster cornices or mouldings are cast from a mould and then fixed to the wall or ceiling. The process involves mixing plaster with water, pouring it into a mold, and then running the plaster to create a consistent, intricate design.

2. Coving and Cornices: Coving refers to a rounded moulding at the junction of walls and ceilings, while cornices tend to be more intricate and often feature elaborate patterns or reliefs. Running moulds are used to create these continuous, curved profiles.
