Product Description

Thistle Hardwall is a gypsum undercoat plaster for use on most masonry. With a final coat of Thistle Multi-Finish, it provides a smooth, inert, high quality surface to internal walls. The combination has superior impact resistance, earlier surface drying, a higher than normal resistance to efflorescence, and gives a durable base for the application of decorative finishes. Thistle Hardwall is a lightweight, retarded hemihydrate, pre-mixed gypsum plaster, incorporating special aggregates and additives, requiring only the addition of clean water to prepare it for use. 

Suitable for use on most masonry backgrounds such as bricks, medium-density and aircrete blocks.

APPLICATION

Thistle Hardwall should be applied with firm pressure, built out to the required thickness, ruled to an even surface and lightly scratched to form a key for Thistle Multi-Finish. For machine application, the plaster should be sprayed on to the background in the form of a ribbon. The consistency should allow the ribbons to run together. When a substantial area is covered, Thistle Hardwall is worked and ruled as in hand plastering. It is easier to attain the required thickness of plaster in one application by machine, but the total thickness should not normally exceed 25mm (subject to background suitability)
