5. **Sanding Tools:** Sandpaper, sanding block, or electric sander for smoothing surfaces.
6. **Trowels:** A variety of sizes for applying and smoothing plaster.
7. **Mixing Tools:** Buckets, mixing paddle, and a drill for preparing plaster mixtures.
8. **Protective Gear:** Safety glasses, gloves, and a dust mask for safety.
**Steps:**
1. **Prepare the Surface:**
– Clean the walls thoroughly, removing any dust, dirt, or loose particles.
– Apply a primer to create a suitable base for the plaster.
2. **Address Wall Imperfections:**
– Fill any cracks or holes with joint compound.
– Apply joint tape over seams for added reinforcement.
3. **Mix Gypsum Plaster:**
– Follow the manufacturer’s instructions for mixing gypsum plaster.
– Ensure a smooth and lump-free consistency.
4. **Apply First Coat:**
– Use a trowel to apply the first coat of gypsum plaster evenly over the wall.
– Work in small sections, spreading the plaster in a thin layer.
5. **Embed Joint Tape:**
– Press joint tape into the wet plaster along seams or areas that require reinforcement.
6. **Second Coat Application:**
– Once the first coat is dry, apply a second coat, smoothing it over the entire surface.
– Use a larger trowel for a broader, more even application.
7. **Feathering Edges:**

8. **Drying Time:**
– Allow each coat to dry thoroughly before proceeding to the next stage.
– Follow the recommended drying times specified by the plaster manufacturer.
9. **Sanding:**
– Once the plaster is completely dry, use sandpaper, a sanding block, or an electric sander to smooth the surface.
– Sand in circular motions to achieve an even and polished finish.
10. **Inspect and Touch Up:**
– Inspect the walls for any remaining imperfections.
– Apply additional coats of plaster or joint compound as needed.
11. **Final Coat:**
