Tools and Materials Needed

Before starting, gather the following tools and materials:

Tools:

  • Plastering trowel
  • Hawk board
  • Mixing bucket
  • Plasterers’ float
  • Sandpaper
  • Paint roller (for PVA application)
  • Spirit level
  • Joint tape (for cracks)

Materials:

  • Plaster (multi-finish or bonding plaster)
  • Water
  • PVA (Polyvinyl Acetate) adhesive
  • Dust sheets
  • Sponge or soft cloth

If you’re unsure about the materials needed, consulting an experienced plasterer Doncaster at Plastering Doncaster can provide clarity.


Step 1: Prepare the Wall

Proper preparation is the foundation of good plastering. Here’s how to prepare your wall:

1. Clear the Area

Remove furniture, decorations, and fittings to create a clear workspace. Lay down dust sheets to protect floors.

2. Clean the Surface

Ensure the wall is clean and free of dust, grease, or loose debris. Use a damp cloth or sponge to wipe it down.

3. Repair Cracks and Holes

Fill any significant cracks or holes with joint tape and a layer of filler. Let it dry before moving to the next step.

4. Apply PVA Adhesive

Mix PVA with water (in a 1:4 ratio) and apply it to the wall using a paint roller. This helps the plaster adhere properly. Allow the PVA to dry until it becomes tacky.


Step 2: Mix the Plaster

1. Choose the Right Plaster

For most internal walls, multi-finish plaster is suitable. For uneven or damaged walls, bonding plaster might be required.

2. Mix Correctly

In a clean bucket, slowly add plaster to water (never water to plaster) while stirring. Use a paddle mixer for a smooth consistency, resembling thick cream.


Step 3: Apply the First Coat of Plaster

1. Load the Hawk Board

Scoop a small amount of plaster onto your hawk board.

2. Spread the Plaster

Using your trowel, apply the plaster to the wall in thin, even strokes. Start at the bottom and work your way up. Aim for a thickness of about 2mm for the first coat.

3. Smooth the Surface

Once the wall is covered, use a straight edge or spirit level to remove excess plaster and ensure a flat finish.

4. Allow to Set

Let the first coat dry slightly until it becomes firm but still damp. This usually takes 20–30 minutes.

For large or complex walls, consider hiring a professional plasterer Doncaster from Plastering Doncaster to ensure efficiency and precision.


Step 4: Apply the Second Coat of Plaster

1. Prepare the Surface

Dampen the first coat lightly with a sponge or spray bottle to prevent the second layer from drying too quickly.

2. Spread the Second Coat

Apply a thinner layer (around 1mm) of plaster over the first coat. Work methodically, ensuring all areas are covered.

3. Smooth the Surface

Use long, sweeping motions with your trowel to achieve a smooth finish. Pay attention to corners and edges for a professional look.


Step 5: Final Smoothing and Polishing

1. Trowel Over the Surface

As the plaster begins to set, trowel over the surface to smooth out imperfections. A clean trowel works best for this step.

2. Polish the Plaster

Lightly dampen the surface with a sponge and use your trowel to polish the wall. This step gives the wall a smooth, glossy finish.

3. Inspect and Touch Up

Check for any missed spots or uneven areas. Address them immediately while the plaster is still workable.


Step 6: Allow the Plaster to Dry

Plaster takes 2–7 days to fully dry, depending on the room’s temperature and humidity. Avoid painting or decorating until the plaster turns a uniform light pink color.


Common Mistakes to Avoid

1. Improper Mixing

Failing to mix plaster correctly can lead to lumps and an uneven application. Always mix thoroughly.

2. Skipping PVA Application

Neglecting PVA can cause the plaster to crack or fail to adhere properly.

3. Overworking the Plaster

Working the plaster too much after it starts setting can create rough patches.
