How to Plaster a Wall like a Pro: A Step-By-Step Guide

Plastering With Hand

Plastering a wall is a task that can seem daunting, but with the right tools and techniques, it can be a satisfying DIY project. The process is similar whether you’re repairing damaged areas or completely plastering a new wall. In this article, we’ll go through the steps of plastering a wall, from preparation to finishing touches.

Tools and Materials Needed


You need to gather the following tools and materials before you begin:

  • Plaster
  • Trowel
  • Jointing knife
  • Bucket
  • Water
  • Sandpaper
  • Drop cloth or plastic sheeting
  • Mixing drill or paddle
  • PVA glue
  • Paintbrush
  • Spirit level
  • Plasterer’s hawk



Before you start plastering, it’s essential to prepare the wall. The first step in preparing your wall for plastering is removing wallpaper, loose paint, or other debris. This is important because plaster cannot adhere to surfaces covered in wallpaper or loose paint. Use a wallpaper scraper or paint scraper to remove any existing wallpaper or paint. If any stubborn areas won’t come off, use sandpaper to smooth them out.

Next, it’s time to fill any holes or cracks in the wall. Use a suitable filler, such as a joint compound or spackle, to fill any gaps or holes in the wall. Apply the filler using a putty knife, ensuring the surface is completely covered. 

Once the filler is dry, use sandpaper to smooth the wall’s surface. Sand until the surface is completely smooth and even. Be sure to dust off the wall thoroughly after sanding to remove any debris or dust that may have accumulated.

Finally, before you start plastering, it’s essential to protect any furniture or flooring in the room. Cover any furniture or flooring with drop cloths or plastic sheeting to protect them from plaster splatters. This will save you time and money on clean-up.

Mixing the Plaster


To begin, you will need a bucket, a mixing drill or paddle, and the plaster powder. But before you start, wear protective gear plasterers use, such as gloves and a mask, to avoid inhaling dust.

Start by adding the plaster powder to the bucket. Measuring the amount of powder accurately is vital to get the right consistency. Most manufacturers provide instructions on how much powder you need per gallon of water.

Next, add the water slowly to the powder while mixing with the drill or paddle. It’s essential to mix the plaster thoroughly to avoid any lumps.

Once you have mixed the plaster, let it sit for a few minutes to allow any lumps to dissolve. After a few minutes, mix it again to ensure that it’s smooth and creamy.

Applying the Plaster


Using a wide paintbrush, apply a coat of PVA glue to the wall. This will help the plaster adhere to the wall better. Let it dry completely before moving on to the next step.

Now, using a trowel and plasterer’s hawk, scoop up some plaster and spread it on the wall. Start at the bottom of the wall and work your way up, using the trowel to smooth the plaster out. Ensure the plaster is evenly spread and there are no bumps or ridges.

Once you’ve covered the entire wall, use a straight edge or spirit level to smooth out the plaster, removing any excess. This will create a flat and even surface.

Finishing Touches


After the plaster dries for about 20-30 minutes, use a jointing knife to smooth out rough spots or ridges. This will create a smooth surface for painting or wallpapering.

When the plaster has dried completely, use sandpaper to smooth out any imperfections or bumps. Wipe the wall down with a damp cloth to remove any dust.



Plastering a wall can seem daunting, but it can be a satisfying DIY project with the right tools and techniques. Remember to prepare the wall properly, mix the plaster thoroughly, and apply it evenly. With a bit of practice and patience, you can achieve a professional-looking finish.
