Smooth walls are essential for creating a visually appealing and professional finish in any space. Whether you’re renovating your home or working on a new construction project, achieving a smooth surface is crucial before applying paint or wallpaper. Skimming and plastering techniques are widely used to achieve this desired outcome. In this guide, we will explore the process of skimming and plastering, providing you with valuable insights into achieving smooth plasterboard solutions for a flawless finish.
Understanding Skimming and Plastering
Skimming and plastering are techniques used to create a smooth and even surface on walls and ceilings. Skimming involves applying a thin layer of finishing plaster, also known as skim coat, over existing plasterboard or plastered surfaces. Plastering, on the other hand, is the process of applying several layers of wet plaster mixture directly onto brickwork, blockwork, or other surfaces to create a smooth and level base.
Preparing for Skimming and Plastering
Before you begin skimming or plastering, it’s crucial to prepare the surface properly. Start by ensuring that the walls are clean, free from dust, and any loose or flaking paint. Repair any cracks or holes using a suitable filler and allow it to dry completely. Sand the surface lightly to create a smooth and even base, ensuring a better bond between the plaster and the wall.
Applying the Skim Coat
To achieve a smooth surface, it’s important to apply the skim coat correctly. Mix the skim coat plaster according to the manufacturer’s instructions. Using a trowel, apply the plaster in thin, even layers, starting from the top and working your way down. Ensure that each layer is completely dry before applying the next one. To achieve a flawless finish, sand the surface lightly between coats to remove any imperfections and create a smooth texture.
Professional Plastering Techniques
If you are starting with a bare surface, plastering is the way to go. Here are some professional techniques to ensure a smooth and seamless finish:
Prewetting the Surface: Before applying the plaster, prewet the surface with clean water. This prevents the dry wall from absorbing moisture too quickly, allowing for better workability and adhesion.
Applying the Scratch Coat: The scratch coat is the first layer of plaster applied directly to the surface. Use a plastering trowel to spread the mixture evenly and at a consistent thickness. Create a textured surface by scratching it with a nail float or a comb float. This helps the next layer of plaster adhere more effectively.
Applying the Skim Coat: After the scratch coat has dried, apply the skim coat. Use a steel trowel to spread the plaster in smooth, even strokes. Maintain a wet edge while working to ensure a seamless finish. Feather the edges to blend them with the surrounding surface.
Final Smoothing: Once the skim coat is dry, use a wet sponge or a damp cloth to smooth out any imperfections. Gently wipe the surface in circular motions, applying light pressure. This process helps to create a flawless finish by removing any blemishes or uneven spots.
How to Hire a Professional Plasterer?

Second, ask to see examples of the plasterer’s work. And finally, be sure to get everything in writing, including the price, the scope of work, and the timeline.
