Detailed Preparation
Inspect and Prepare the Wall: Carefully examine the wall for any cracks, holes, or moisture issues. Repair any damages before starting.
Surface Cleaning: Use a brush or vacuum to clean the wall thoroughly. If necessary, wash the wall and allow it to dry completely.
Preparing the Wall for Plastering
Before you begin plastering, preparing the wall is crucial to ensure a smooth and lasting finish. This section outlines the essential steps:
Cleaning and Clearing
Surface Cleaning: Remove dust, dirt, and any flaky paint. For greasy walls, use sugar soap or a suitable cleaning agent.
Clear the Area: Move furniture away and lay down dust sheets to protect the flooring.
Addressing Wall Issues
Repairing Damage: Fill any holes or cracks with an appropriate filler and sand down once dry.
Dampness Check: Address any signs of dampness before plastering, which might require professional assessment.
Surface Preparation
Scoring Old Paint: If the wall has glossy paint, lightly score it with sandpaper to help the plaster adhere better.
Applying PVA: For smooth surfaces or where old paint has peeled, use a PVA (Polyvinyl Acetate) mix to provide a good base for the plaster.
Setting Up Tools and Materials
Ready Your Tools: Have all your tools and materials within reach to streamline the plastering process.
In-depth on Plaster Types
Different Plaster for Different Surfaces: Understand that gypsum plaster is ideal for dry areas, while cement-based plaster is better for damp conditions.
Undercoat Plaster: Learn about undercoat plaster for uneven walls that need levelling.
Comprehensive Tools and Materials List
Complete List of Tools: Make sure you have a hawk, a variety of trowels (including a corner trowel), a mixing stick or drill with a mixing paddle, a bucket, and a spirit level.
Preparing Your Workspace: Lay down dust sheets and tape off areas to protect from splatters.
Mastering the Mix
Mixing Technique: Mix the plaster in clean water until it is creamy. Avoid overmixing, which can introduce air bubbles.
Step-by-Step Application Process
Enhancing the details in this section will guide you through a more intricate and compelling plastering process:
Applying the First Coat (Scratch Layer)
Mix Consistency: Ensure the plaster mix is creamy but not too runny.
Applying Techniques: Use the trowel to apply the plaster in upward strokes. Aim for a uniform thickness of about 2-3 mm.
Creating a Key: Once the first layer is slightly firm, gently scratch the surface with a plasterer’s comb or similar tool, as this creates a key for the next layer.
Applying the Second Coat (Floating Layer)
Thickness: Apply a second layer, slightly thicker (about 2 mm) than the first, ensuring it’s smooth and level.
Smooth Out: Use a clean trowel to smooth the surface, filling in gaps or indentations.
Applying the Final Coat (Finishing Layer)
Fine Finish: Mix a thinner, smoother plaster for the final layer. Apply it finely to fill in any imperfections.
Polishing: After slightly drying, polish the surface using a clean, somewhat wet trowel for a smooth finish.
Expert Tips for Application
Consistent Pressure: Apply constant pressure when spreading the plaster for even layers.
Edge and Corner Technique: Be meticulous around edges and corners for a neat finish.
Temperature and Humidity Considerations: Be mindful of the room’s temperature and humidity, as they can affect drying times.
Drying, Sanding, and Finishing
Optimal Drying Conditions: Ensure good ventilation but avoid direct drafts, which can cause the plaster to dry too quickly.
Sanding Tips: Use fine-grit sandpaper and sand lightly to avoid creating indentations in the plaster.
Final Checks: Look for any missed spots or blemishes to touch up.
Painting and Decoration
Sealing the Plaster: Seal the plaster with a mist coat of paint or a specific plaster sealer.
Choosing the Right Paint: Consider the room’s use and the plaster type when selecting paint.
