Plastering
There are quite a few plasters but two main types - gypsum based and cement based. The latter are used mainly for outdoors, generally for rendering. Gypsum based plasters are used indoors only - damp will attack a gypsum based plaster and cause it to crumble.

Cement based plasters can be used indoors for areas that are susceptible to damp and areas that require a greater thickness of cover.
