Skim coat意思

"Skim coat" is a term used in construction and home improvement, specifically in the context of finishing drywall or plaster surfaces. It refers to a thin layer of a mixture, typically a combination of water, joint compound (also known as drywall mud), and sometimes additional bonding agents or additives, that is applied to a wall or ceiling to create a smooth finish.

The skim coat is applied with a trowel or a special applicator, and it is used to cover minor imperfections in the surface, such as small holes, cracks, or rough areas. It can also be used to create a smooth base for wallpaper or to prepare a surface for painting.

Skim coating is often the final step in preparing a wall or ceiling for finishing, and it is important to apply the skim coat evenly and smoothly to ensure a professional-looking finish. Once the skim coat is applied, it is typically left to dry and then sanded smooth before any final painting or wallpapering is done.
