Objectives
Trainees are …
- able to organize building site, materials and tools for plaster/render
- aware of health and safety correlated to other workers, building site, machinery, equipment, PPE (personal protective equipment) and of issues specific to working with clay
- able to explain the structure of a clay plaster/render with it’s several layersable to apply the 1st base coat of a multilayer plaster/render
- able to apply the base “filling layers” to make the wall even
- able to apply a reinforcement mesh
Method:
- practical exercises at a workshop or building site together with theoretical support
Theory:
- how and why to create a 1st layer to stick the plaster/render on the straw
- the structure and composition of clay multilayer plaster/render with their different thickness
- drying time of the different layers and ventilation procedures to ensure drying
- connection between layers: texturize and wet the surface
- the protection of a drying plaster/render from weather conditions
Practice/Task:
- Exercises:
- to apply a clay slip by hand or using a mechanic spray
- to apply base layers with clay and straw to achieve an even wall
- to reinforce by applying mesh
- to check the thickness to guarantee bracing function as load bearing material
- to check good execution to guarantee a minimum thickness for working fire protection, air tightness, water proof, phonic insulation and rodents and insects protection
Materials/Documents: U5 S4 – Session Plan
Training Time: 1 day
