The West Australian Solid Plastering Association (WASPA) is dedicated to promoting the art of solid plastering within the West Australian building industry.

In 1996 a group of Western Australia's leading plasterers, suppliers, manufacturers, and training professionals met to develop ways of maintaining and improving plastering standards. The diverse backgrounds of it's inaugural members allowed WASPA to emerge as the only fully incorporated not-for-profit organisation in WA representing the full spectrum of Western Australia's solid plastering industry.

Today, the West Australian Solid Plastering Association provides an extensive range of products and services to plasterers, builders, architects, designers, hardware retailers, manufacturers, colleges, and members of the public throughout the state. WASPA recognises and rewards quality workmanship by actively promoting businesses that express a commitment to excellence in solid plastering.
