How to Plaster Wall
To plaster a wall, you will need a good set of tools including a plastering trowel, plasterer’s hawk board, bucket trowel, power mixer, and a paint brush.
Before starting, remove furniture and other fixtures from the wall and tape up sockets to protect them.
Lay down protective sheets on the floor to prevent dust contamination.
Clean the wall thoroughly, removing wallpaper, loose plaster, grease, and dust.
Apply plaster tape to cover joints in new plasterboard and trim it with a sharp knife.
Follow the manufacturer’s instructions to apply diluted PVA glue to the wall.
Always follow the manufacturer’s instructions when mixing plaster, using clean tap water.
Use a bucket trowel to incorporate any dry plaster around the edge of the bucket.
Use a power mixer at a low speed to mix the plaster until it is smooth and free from lumps, with the consistency of “thick custard”.
Clean the power stirrer before the plaster sets.
For large areas, pour the plaster onto a spot board and transfer a small amount to a hawk board.
Use a plastering trowel to spread the plaster firmly on the wall in upward strokes, angling the trowel away from the wall.
Flatten the trowel at the end of each stroke to smooth the plaster down.
Work from the bottom left corner of the wall upwards and outwards, using a small amount of plaster each time.
Allow the first coat of plaster to dry slightly for about 20 minutes, then smooth out any bumps with a trowel.
Spray water on sections of the plaster to make it respond better to the trowel.
Apply a second, slightly thinner coat of plaster following the same steps as the first coat.
Let the plaster dry according to the manufacturer’s instructions.
Finally, go over the surface lightly with a clean trowel blade, dampening it with a spray bottle, and angling the blade slightly to smooth over the plaster.

Preparing The Wall For Plastering
Before you start plastering, it is crucial to prepare the wall properly to ensure a successful finish. Follow these steps to ensure your wall is ready for plastering:
- Remove Furniture and Fixtures: Clear the area by removing any furniture, curtain rails, dado rails, and radiators from the wall you will be plastering. This will prevent any obstructions during the plastering process.
- Tape Up Sockets: To avoid any plaster getting into electrical sockets or switches, it is essential to tape them up securely. Use masking tape or electrical tape to cover and protect them from any damage.
- Lay Protective Sheets: Plastering can be a messy job, so it is vital to protect your floor from dust and debris. Lay down protective sheets, such as plastic or old sheets, to create a barrier between the plaster and the floor.
- Clean and Scrub the Wall: Ensure that the wall is clean and free from any loose plaster, wallpaper, grease, or dust. Use a scraper or wire brush to remove any stubborn materials, ensuring a smooth surface for the plaster to adhere to.
- Plaster Tape: If you are working with new plasterboard, apply plaster tape to cover joints and corners. Trim the tape with a sharp knife to create clean edges. This step will prevent cracking and create a strong foundation for the plaster.
- Diluted PVA Glue: Before applying the plaster, seal the wall with a diluted PVA glue solution. Follow the manufacturer’s instructions to prepare the glue, then apply it evenly, ensuring full coverage of the wall surface. This helps the plaster adhere better to the wall.
Mixing And Applying Plaster
Now that the wall is prepped, it’s time to mix and apply the plaster. Follow these steps for a smooth and consistent mixture:
- Follow Manufacturer’s Instructions: When mixing plaster, always refer to the manufacturer’s instructions. Different brands may have specific guidelines for water-to-plaster ratio and mixing times.
- Use Clean Tools and Water: Ensure that your bucket and power mixer are clean to avoid any contamination. Fill the bucket with clean tap water, as any impurities may affect the plaster’s quality.
