• Stucco: Used for exterior walls, it is a decorative and protective coating that can withstand harsh weather conditions.

2. What are the key factors to consider when selecting the appropriate plastering material for a specific project?

• Subsurface conditions: The type of surface being plastered, its condition, and exposure to moisture.
• Project requirements: The desired finish, durability, and aesthetic considerations.
• Environmental factors: Temperature, humidity, and ventilation conditions that may affect the plaster’s performance.
• Cost and availability: The budget and availability of different plastering materials.

3. Describe the steps involved in preparing a surface for plastering.

Surface preparation is crucial for successful plastering:

• Cleaning: Removing dirt, dust, and any existing finishes.
• Repairing: Filling cracks, holes, and other imperfections.
• Priming: Applying a bonding agent or primer to enhance adhesion.
• Keying: Creating a rough surface to improve the plaster’s mechanical bond.

4. What are the techniques used to apply plaster and achieve different finishes?

• Floating: Applying the plaster in a thin, even coat to create a flat surface.
• Troweling: Smoothing and compacting the plaster, producing a smooth finish.
• Floating and troweling: Combining the two techniques to achieve a flawless surface.
• Texturing: Using tools or additives to create decorative patterns or textures.
• Coloring: Adding pigments or dyes to the plaster for a colored finish.

5. How do you ensure the plaster is properly cured and protected during the drying process?

Proper curing is vital for the plaster’s durability:

• Maintaining moisture: Keeping the plaster moist by misting or covering it with plastic sheets.
• Controlling temperature: Maintaining a consistent and moderate temperature to prevent rapid drying and cracking.
• Protecting from direct sunlight: Covering the plaster with shade or tarps to prevent overheating and cracking.
• Allowing sufficient drying time: Providing adequate time for the plaster to fully cure, typically several days or weeks.

6. How do you handle and troubleshoot common problems that may arise during plastering?

Understanding and addressing common problems ensures successful plastering:

• Cracking: Caused by improper curing, excessive shrinkage, or movement of the substrate.
• Blistering: Caused by trapped air or moisture beneath the plaster.
• Efflorescence: Salt deposits appearing on the surface due to moisture evaporation.
• Poor adhesion: Caused by inadequate surface preparation or incompatible materials.

7. What are the safety precautions to be taken when working with plaster?

• Wearing protective gear: Respirator, gloves, and eye protection to prevent inhaling dust and contact with wet plaster.
• Proper ventilation: Ensuring adequate airflow to prevent dust and moisture accumulation.
• Avoiding direct skin contact: Wearing gloves to protect skin from irritation.
• Handling wet plaster with care: Preventing splatter or spills that could cause injury.
