About Solid Plastering

The art of solid plastering or rendering, as it is commonly called, dates back to well before ancient Roman times where mixtures of lime, sand and volcanic ash were used over rough mud or block walls. Before this time, both stone and clay and straw huts were also plastered internally to offer a smooth, softened interior for dwellers. Towards the time of the middle-ages, solid plastering took on more decorative forms to improve the aesthetic appearance of both internal and external walls. Even Leonardo da Vinci plastered the walls of the Sistene Chapel in a base relief (which gave the walls a 3D effect) before painting his masterpieces during the Renaissance years.

Preserving and upholding some of these techniques, solid plastering today, has evolved to include new styles, textures and patterns of render applications over an increasingly wide range of building substrates from brick and block, through to plasterboard, concrete and light weight energy efficient walling such as polystyrene.

Rendering or solid plastering a wall not only improves the durability, water tightness, acoustic and thermal properties of the surface, but also dramatically improves its overall look and appearance.
