• plasterboards – The foundation for modern wall finishes
• plaster – For a smooth, durable coat
• Plastering trowel – For applying and smoothing plaster
• Hawk board – To hold and transfer plaster
• Mixing bucket and drill mixer – For preparing the plaster mix
• Joint tape (Scrim Tape) – To reinforce joins between plasterboards

Step-by-Step Guide: How Do I Plaster a Wall?

Step 1: Preparing the Wall

2. Start from the top and work your way down in thin, even layers.
3. Apply a second coat once the first layer is semi-dry for a smoother finish.

Step 4: Smoothing and Finishing
