Concrete stucco is a cement-based finish coat applied to walls or ceilings to create a smooth, hard-wearing surface. Unlike traditional gypsum plaster, concrete stucco uses cement as its binder, making it harder, more water-resistant and more durable.
Properties
- Water-resistant — suitable for wet rooms such as bathrooms, basements and utility rooms
- High strength — harder than gypsum plaster, resistant to impact and abrasion
- Good adhesion — bonds well to concrete substrates
- Longer working time — dries more slowly than gypsum, allowing more time for finishing
- Shrinkage-prone — hairline cracks may occur if not applied correctly
Application
Concrete stucco is used where a robust, moisture-resistant finish is required:
- Bathrooms and shower rooms — as a base for tiles or as a visible finish coat
- Basements — protection against rising damp
- External walls — as part of an external render system
- Industrial spaces — where an abrasion-resistant wall is needed
Difference from gypsum plaster
Gypsum plaster is lighter, easier to work with and faster drying, but is not suitable for wet rooms. Concrete stucco is heavier and harder, but water- and frost-resistant.
