Tencuieli

Tencuieli, a Romanian term, refers to the process of plastering or rendering walls, typically for interior and exterior finishing. This traditional building technique involves applying a layer of mortar to surfaces to create a smooth, level, and durable finish. The mortar commonly used in tencuieli is a mixture of lime, sand, and water, though cement and gypsum are also incorporated into modern formulations to enhance strength, adhesion, and drying times.

The application of tencuieli is a skilled craft. The mortar is usually applied in two or three coats. The first coat, known as the scratch coat or render coat, is a rougher mixture that is scratched to provide a key for subsequent layers. The second coat, the brown coat or float coat, is applied to achieve a level surface. Finally, a finishing coat, often a finer plaster or skim coat, is applied to create the desired aesthetic, whether it's a smooth, polished surface or a textured finish.

Tencuieli serves multiple purposes. It protects the underlying masonry from the elements, improving insulation and soundproofing. It also provides a clean and uniform surface ready for decoration, such as painting or wallpapering. Historically, tencuieli was essential for creating habitable structures, offering protection and aesthetic appeal. Today, while modern materials like drywall are common, traditional tencuieli techniques are still valued for their durability, breathability, and the natural aesthetic they provide, particularly in restoration projects and in certain architectural styles.
