Do you have dampness affecting the interior walls of your home? Plastering is a great way to not only fix the issue but also enhance the aesthetic appeal of your living space. In this guide, we’ll walk you through the steps to properly plaster a damp interior wall, ensuring a smooth finish that’ll last for years to come.

Gathering the necessary tools and materials

Before you start plastering, it’s important to have all the required tools and materials at your disposal. Here’s a list to help you get organized:

  • Plastering trowel
  • Bucket
  • Plaster mix (water-resistant formula if dealing with dampness)
  • Filling knife or scraper
  • Dust sheets
  • Sanding block or sandpaper
  • Primer
  • Paint
  • Paintbrush or roller

Preparing the wall surface

Proper preparation is crucial to ensure a successful plastering job. Follow these steps:

  1. Remove any loose or flaking plaster using a filling knife or scraper.
  2. Brush off any dust and debris from the wall surface.
  3. If there’s mold present, clean it thoroughly using a solution of bleach and water.
  4. Allow the wall to dry completely before proceeding to the next step.

Applying the base plaster coat

Now it’s time to apply the base coat of plaster to the wall:

  1. Add water to the plaster mix, following the manufacturer’s instructions. Use a bucket to achieve the desired consistency.
  2. Apply a thin base coat of plaster to the wall using a plastering trowel. Work from the bottom up, applying upward strokes.
  3. Ensure the entire wall surface is covered with a uniform layer of plaster by feathering the edges as you go.

Allowing the base coat to dry

Once the base coat is applied, give it sufficient time to dry. Refer to the plaster mix packaging for recommended drying times.

Applying the finishing coat

Now it’s time to achieve that smooth, flawless finish:

  1. Prepare another batch of plaster mix, following the instructions.
  2. Apply the finishing coat to the wall in the same manner as the base coat, smoothing it out with the plastering trowel.
  3. Make sure to feather the edges to blend the new plaster with the existing wall surface.

Finishing touches for a professional look

Finally, make some finishing touches to complete the plastering process:

  1. Once the plaster is completely dried, use a sanding block or sandpaper to smooth out any imperfections and create a seamless surface.
  2. Clean up any remaining dust from the wall using a soft cloth or brush.
  3. Apply a primer to the plastered wall to create a suitable surface for painting.
  4. Once the primer is dry, paint the wall using your desired color, applying multiple coats if necessary. Use a paintbrush or roller for a professional finish.

By following these steps, you’ll be able to properly plaster a damp interior wall, transforming it into a visually appealing space while eliminating the dampness issue. Remember to gather all the necessary tools and materials, prepare the wall surface, apply the base and finishing coats, and complete the process with some finishing touches for a flawless result. Enjoy your newly plastered wall!
