The most commonly specified wet plaster is Thistle Hardwall, a gypsum based undercoat plaster that can be used on most masonry. With a final coat of Thistle Multifinish it provides a smooth, inert, high quality surface to internal walls.

The combination has a superior impact resistance, earlier surface drying and provides a durable base for the application of decorative finishes.

The recent increases in steel prices has led to more use of internal blockwork which in turn increases the likelihood that two coat plaster is used rather than drywall systems, primarily because the British market is highly price sensitive.
