Skim coat, also known as a thin coat, is a process of applying a thin layer of cement-based or gypsum-based material over a rough or uneven surface to create a smooth, flat finish. It is commonly used in construction and renovation projects to prepare surfaces for painting, wallpapering, or tiling.
Skim coating can be done on various surfaces such as concrete walls, drywall, and ceilings. The material used for skim coating is typically a mixture of water and a cement or gypsum-based powder, which is then applied to the surface using a trowel or a plastering tool.
The process of skim coating requires skill and precision, as it is important to apply the material evenly and smoothly to achieve a flat finish. Skim coating can be time-consuming and may require multiple coats to achieve the desired results, but it can significantly improve the appearance of a surface and provide a suitable base for further decorative treatments.
