Granite plaster and marble plaster are decorative renders in which fine granite or marble granules are incorporated, creating a speckled, natural-stone appearance. They combine a strong, hard-wearing finish with an attractive, robust look.
Build-up and function
The plaster consists of a binder — often resin- or cement-based — mixed with coloured stone granules of granite or marble. After application and curing, a hard, closed surface is formed that resists impact, scratching and moisture well. The colour is in the granules themselves and therefore stays attractive for a long time.
Application
Granite and marble plaster are widely used where a surface has to take some punishment:
- Facade plinths — the lowest, most heavily loaded zone of the facade
- Stairwells and porches — hard-wearing wall finish in communal areas
- Basements and garages — moisture- and impact-resistant walls
- Bases and piers — as an accent and protection at the foot of the facade
Advantages and points of attention
- Advantage — hard-wearing, impact-resistant and colourfast
- Advantage — gives a natural-stone look at lower cost
- Point of attention — the substrate must be flat, firm and dust-free
- Point of attention — a closed plaster can reduce the vapour permeability of the facade
