or finishing coat plastering is the final layer of plaster which, when done well, should leave a wall or ceiling ready for decoration.
Traditional plastering consists of two or three coats of plaster. The plaster may use strips of wood or metal (lathe
) as a base onto which plaster is applied or can be applied directly onto brick (Plaster on Hard
). Though this method offers good sound and heat insulation it is both labour and materials intensive and so relatively expensive.
A modern equivalent is to apply a skim coat of plaster directly onto plasterboard which will give something of the quality and feel of traditional plastering.
A further alternative to "skimming" plaster board walls is to "tape the joints". Often referred to as Ames
Taping this, in simply terms, uses plaster and tape to fill the joints where sheets of plasterboard meet.
