Plastering an external wall can be a daunting task, but with the right tools and techniques, it is certainly a DIY project you can tackle. In this step-by-step guide, we will walk you through the process of plastering an external wall, ensuring a smooth and professional finish.

What You Will Need

  • Plastering trowel
  • Hawk (a small square board with a handle)
  • Mixing bucket
  • Plaster (pre-mixed or powdered)
  • Waterproofing additive (if required)
  • Fine aggregate (if required)
  • Fabric mesh (if required)
  • Measuring jug
  • Protective gear (goggles, gloves)
  • Scaffolding or ladder (if necessary)

Step 1: Preparing the Wall

Before you can start plastering, it is crucial to properly prepare the external wall. Make sure the surface is clean, free from dust, dirt, and loose particles. Remove any flaking paint or old plaster using a scraper or wire brush. Additionally, ensure that any cracks or holes on the wall are filled and repaired.

Step 2: Mixing the Plaster

Start by carefully measuring the required amount of plaster and placing it in a mixing bucket. If you are using powdered plaster, follow the manufacturer's instructions to achieve the correct consistency. Gradually add water while stirring continuously until you achieve a smooth, lump-free mixture. For extra durability, you can add a waterproofing additive or fine aggregate to the mix, ensuring it adheres better to the wall.

Step 3: Applying the Plaster

Now, it's time to start applying the plaster to the prepared external wall:

  • Take a small amount of plaster onto your hawk.
  • Hold the hawk with one hand and scoop a little plaster onto the trowel using your other hand.
  • Start from the bottom of the wall and work your way up, applying the plaster in an upward motion.
  • Hold the trowel at a slight angle against the wall, spreading the plaster evenly in thin layers.
  • Continue this process, working on small sections at a time, until the whole wall is covered.
  • Smooth out any bumps or ridges using the trowel, ensuring a flat surface.

Step 4: Applying Multiple Layers

In most cases, one layer of plaster might not be sufficient. To achieve an even and robust finish, it is recommended to apply multiple layers. Allow each layer to dry before adding the next. Before applying the next coat, make sure to dampen the previous layer slightly to ensure better adhesion.

Step 5: Finishing Touches

Once all the layers are applied and dry, inspect the plastered wall for any imperfections or rough edges. Use a damp sponge or fine grit sandpaper to smooth out any uneven areas and achieve a polished finish. If necessary, apply a final thin coat for a flawless appearance.

Congratulations! You have successfully plastered your external wall. Now, take some time to admire your handiwork and allow the plaster to fully dry before considering any further decoration such as painting or rendering.

Remember, plastering requires practice to master. Don't be disheartened if your first attempt isn't perfect. With time and experience, you will improve your technique and achieve professional results.
