Best describes the form work for wet plaster

• A. Plaster grounds
• B. Lath
• C. Scaffolding
• D. Form Ties

Answer: (A)

The formwork for wet plaster is provided by plaster grounds—the prepared backing that receives the plaster and gives it a shape and key as it cures. This ground can be rough wood lath or another suitable backing, but its main role is to hold the wet plaster in place and provide adhesion so it doesn’t sag or separate as it sets. In traditional plastering, you apply the plaster to this ground in coats, and the ground determines the surface contour you’ll end up with. Scaffolding is only for access, form ties are used in concrete forms, and while lath is the actual backing, the term that best describes the formwork concept for wet plaster is plaster grounds because it defines the surface that contains and supports the plaster.
