How to Plaster a Ceiling Step by Step

So you’re ready to take on plastering your ceiling, are you? Well, just follow the simple steps outlined below and you’ll soon be well on your way!


1. Gather Your Tools and Equipment

Before you begin plastering your ceiling, you will need to gather a few tools first. Keep these handy for the duration of the project. Then, if you need something mid-project it will be close at hand.

We’ve included a list below of the most important tools and supplies for plastering a ceiling:

  • Plaster
  • Plastering trowel
  • Ladder
  • Mixing stick
  • Sandpaper
  • Clean water and sponge

Once you’ve gathered all the essential supplies then it’s time to begin the prep work.


2. Prepare the Area

Plastering a ceiling is messy there is simply no better way to put it. You’re balancing on a ladder with wet plaster on a trowel that you spread across the ceiling. This means, there’s a pretty good chance that some of it is going to drip down and land on your or the surrounding area.

The best way to counteract this is to plan ahead. Remove as much furniture as possible from the room. Then, cover any remaining furniture as well as the floor with a sheet of plastic. Take special care to ensure that the entire floor is covered. You don’t want plaster falling and hardening on your carpeting or hardwood.

To protect yourself, you should wear a renovation mask and some old clothes. While the mask prevents plaster from landing in your mouth, the clothes will protect your skin. Not to mention that using old clothes means you won’t destroy any favourite pieces.

3. Prepare the Ceiling

Do you have uneven patches on your ceiling? Then you should sand these down first. You don’t want the faults of your old ceiling to carry over after you are finished your project.

Then you’ll need to tidy up. Even if your ceiling is newer you should still follow these steps and tidy to remove any hidden dust. The good news is, that cleaning your ceiling is relatively easy. Use a vacuum to remove old cobwebs from the ceiling and then a sponge with some soapy water to wipe up any dust that remains. After this, get rid of any traces of soap residue by sponging the ceiling with clean water after following this step.

Are you plastering on a surface that has been exposed to oil? Then use a degreaser. If you don’t remove the oil before you plaster, it won’t set.

If you have a hole in your ceiling, you will also need to take some steps to patch this up first.

4. Start Mixing Your Plaster

Mixing plaster is relatively easy. The best way to mix plaster is by using equal parts of water and plaster. Then add the plaster to the water using your mixing stick to create a smooth consistency. Once the consistency is just right you can move on to the next step.

5. Plastering Techniques for Skim Coating

Now that you have your plaster all mixed you can begin plastering your ceiling. In order to plaster your ceiling properly, you will need to learn how to skim a ceiling with plaster. This is a pretty simple process but it does require some patience.

Remember that while you are plastering the ceiling you should always have someone nearby to hold the ladder steady. It is important to make safety a top priority.

To skim a ceiling with plaster, first, dab some clean water on the ceiling where you plan to apply the plaster. Then add a small amount of plaster to the edge of your plastering trowel to create a thin, even layer. For your convenience, apply the plaster in rows that are about a metre long. Divide each part of the ceiling into manageable steps and don’t forget to take breaks!

As you apply the plaster you should also use the rough edge of your plaster trowel to create scrapes or scratches in the plaster. Continue this process along the entirety of the ceiling.

Once the ceiling is entirely covered with a skim coat, let it set completely. Depending on the type of plaster you use this could take up to 48 hours. After your plaster is set you can apply a second coat continuing to use the skim coat technique. Together these two fine layers of plaster will contribute to a smooth and even ceiling.


6. Sand and Smooth It Out

No matter how skilled you are at applying a skim coat to your ceiling you’re going to end up with a few bumps along the way. Don’t fret though, this has an easy remedy. Just grab your handy piece of sandpaper that you gathered earlier with your tools. Then, use this to sand the bumps away. With a bit of elbow grease, your ceiling will soon be smooth, even and ready for a coat of paint!

How to Fix a Hole in the Ceiling

Do you have a hole or crack in your ceiling that you need to patch up? Then you’ll need to take a few extra steps first before you begin the plastering process outlined above.


Hole in plaster ceiling


First, brush any loose plaster away You don’t want loose plaster particles around the edge of the hole to compromise your project.

Second, fill the hole with plaster. This will be the first coat of plaster you apply. If you have a lath ceiling, make sure the plaster surrounds the lath. Then let this set completely.

Then, cover the hole with a piece of wire mesh. If the piece of mesh isn’t sticking properly, use wooden dowels to keep it in place. The wire mesh will strengthen the area so that it is sturdy and strong once the project is complete.

Add another layer of plaster over the wire mesh. When the plaster is completely dry, snip off any exposed pieces of wire from the mesh.

Then, sand down the edges of the hole so that they are smooth and even. With proper sanding, you won’t even notice the area where you sanded the hole!

How Much Does It Cost to Plaster a Ceiling?

The two main factors which influence the cost to plaster a ceiling are ceiling size and its general state of repair. Logically, larger ceilings will cost more to plaster than smaller ceilings. Not only does it take longer to plaster a larger ceiling but, you will also need more materials to completely plaster it.

Then, the general state of repair is also a key consideration. If your ceiling is in rough shape and there is more than just a small hole to patch up, this will contribute to a higher cost.

On average, plasterers in the UK charge around £18 per hour. Then, in terms of materials a 25kg bag of dry plaster which you would then mix on your own runs at around £7-15. If you buy pre-mixed plaster, which is ready to use the cost is a little higher with prices ranging between £15-20 for a 6L container.

A 25kg bag will cover about 2.25m² if the layer is about 35mm thick. On the other hand, a 6L container covers about 0.75 m²  when you make the layer 6mm thick.

To get the precise cost for plastering your ceiling, first measure the square footage. Then divide this by the area the bag covers. This will tell you how many bags you need to buy. From this, you will be able to estimate the material cost.
