Plastering for beginners can be tricky. But with practice and the right tools, anyone can learn to plaster walls and ceilings.

From this article, you’ll learn how to prepare and plaster a wall from scratch. And at the end, there’s a video of the process you can watch.

Anyone can plaster a wall, but you need to follow a formula. You can’t just pick up a trowel and start throwing plaster on the walls.

Here are the three main stages of plastering a wall:

  • Knowing what plastering tools and general DIY tools to use
  • Correctly preparing walls for plastering (failing to do this can cause chaos)
  • Plastering the wall

What plastering tools and equipment do you need to plaster a wall or ceiling?

Before you start plastering you need the right tools.

Here are the 5 main tools you’ll need to start skimming. You will eventually strive for a lot more but here are the basic tools you need:

  1. Plastering trowel
  2. Hawk/hand board
  3. Bucket trowel
  4. Mixer
  5. Water brush

1) Plastering trowel

This is obviously the most important tool. This is the tool that will affect your results the most.

So, yes, you need a decent trowel. The one below is a good starting point.

It’s a good size, it’s easy to use and it’s made from stainless steel, which makes it easier to maintain.

If you don’t fancy paying for one of these make sure you don’t buy a cheap and nasty one. It won’t pay off and you won’t get the results you deserve.

2) Plasterer’s hawk

This is another important one because this is the tool that holds your plaster. If you didn’t have one of these you’d have to throw the stuff on the walls!

There are many options but a plastic hawk board, like the one below, is ideal for beginners.

Plastering for beginners can be strenuous and hard on your forearm muscles. So it makes sense to reduce the amount of weight you’re holding, if you can. Plastic hawk boards are lightweight and go a long way to making plastering easier.

The downside to using a plastic hawk board is that they’re not very strong so they won’t last forever. But you can upgrade once you get better at plastering.

3) Bucket trowel

This one isn’t as important. The main function of this tool is to scoop the plaster from the bucket and onto your hawk board.

4) Mixer

A decent plaster mixer is a good investment, even for those just starting out. It automates the mixing process so you don’t wear yourself out before you start plastering!

It mixes the plaster in double the time with little effort and generally creates a nicer, smoother mix. Prices can range from £50 – £300.

5) Water brush

A good water brush is a crucial tool in your arsenal of plastering utensils.

It keeps your edges clean, allows you to splash water onto your plaster and gives your walls a perfect finish. You could use a cheap brush but a more expensive one is a better option.

A cheap brush leaves its bristles on your wall, and can often be more trouble than it’s worth. Consider investing in a real decorator’s brush, like this one.

No products found.

You will also need a small brush to clean all your tools with. Use a decent hand brush that’s small enough to get between the paddle of your mixer.

Keeping your tools clean is one of the most important tasks when plastering. Remember – if you take care of your tools, they’ll take care of you.

What’s next?

How to prepare walls for plastering

You know what tools you need, now it’s time to learn how to prepare your walls. Keep this phrase front and centre – failing to prepare is preparing to fail.

Get this part wrong, and full sheets of plaster could fall from the wall. This is so crucial because weak preparation creates so many problems.

Let’s go through each step of the preparation process so you have the perfect base for skimming.

There are four steps you MUST follow:

  1. Strip wallpaper
  2. Wash down the walls
  3. Scrim tape any cracks
  4. Apply PVA
  5. Start plastering

Let’s delve deeper!

1) Strip wallpaper

This is probably one of the most hated jobs in the history of man (painting skirting boards is another).

Unfortunately, it’s vital for preparing your walls.

If you don’t remove wallpaper before applying new plaster (yes, people do this), you’ll be in a whole load of trouble.

Over time, the wallpaper absorbs moisture from the plaster and starts to fall from the wall. Over a longer period of time, the whole lot could fall from the wall.

This is why you need to remove ALL of the paper before you start plastering.

Yes, it’s hard work and it’s very boring, but in the long run, it’s worth it.

2) Wash the walls down

This isn’t always necessary but many professionals recommend it.

The reason is simple: grime and dirt prevent plaster from sticking. And if plaster doesn’t stick to the wall (or ceiling), it will fall off, bringing surrounding plaster with it.

To avoid a situation like this, wash walls with a mix of sugar soap and water by applying it to the area you want to work on.

This will remove any grime from the surface and prevent any issues with your plaster. (It seems like a pain but it does create an ideal base for plastering.)

3) Scrim tape any cracks

Scrim tape is a self-adhesive mesh tape placed over the joints of plasterboard sheets. When movement occurs the scrim tape prevents the plaster from cracking.

If you have any cracks in your walls, cover them with scrim tape. This stops the plaster from cracking if movement occurs around the cracked area.

4) Apply PVA

It is standard practice to apply No products found. to a wall prior to plastering.

Every wall has its own rate of suction. Which refers to the amount of moisture a material absorbs. Brick, for example, has a very high suction rate. If you throw water on brickwork it will disappear within two minutes.

Applying PVA to a wall or ceiling before plastering slows the suction rate. Which gives you a longer time to apply the plaster before it starts to set. Another perk is that PVA helps the plaster bond to the walls.

Typically, you mix one part PVA with three parts water, give it a good mix and roll it all over the walls. You then have to then wait for the first coat to dry completely and apply a second coat before you can begin plastering.

Just before it dries completely you may find that the PVA is sticky (which plasterers call “tacky”). This is the moment you want to get your mix on and start applying the plaster to the walls. The best time to start skimming is when your walls are slightly sticky, as the plaster binds to the PVA and generally has a better connection.

This is where the 3rd and most important part of plastering comes in.

If you’ve got this far the preparation is over and it’s now time to start skimming.

5) Plastering the walls

Finally, the moment you’ve been waiting for: getting plaster onto your walls.

Mixing the plaster

The first thing to discuss is mixing the plaster.

British Gypsum Multi-Finish plaster is ideal for the job – it’s a great product and can be used on various surfaces, making it perfect to use on your walls. The instructions from British Gypsum (BG), state that you should use 11.5 litres of water per bag of plaster.

This is roughly a full bucket of water to one bag of plaster.

Some pros mix a full bucket of water with an extra litre (roughly 12.5 litres), because they find it gives the best consistency.

Always pour the water in first and add the plaster in stages.

Typically, add one-third of a bag of plaster first, mix the plaster using the mixer, then add another third whilst mixing.

Finally, throw in the final third and finish mixing.

This prevents any plaster from sticking to the bottom of your bucket whilst getting a decent mix to work with.

Always use clean water and never mix in a dirty bucket because you could risk the plaster setting at a faster rate. You want to aim for the plaster to be at a consistency of melting ice cream and the mix to stay on your bucket trowel without sliding off when held level.

Always check the date of the plaster. If it’s past its expiry date then get rid of it – there is nothing worse than using a dodgy batch of plaster.

Following these simple steps will give you the perfect mix for plastering.

Applying the plaster

Now you’re ready to go, so let’s get cracking.

There are six steps to plastering:

  • 1st coat of plaster
  • 2nd coat of plaster
  • Flatten your plaster
  • 1st trowel over
  • 2nd trowel
  • Final polish

Now, instead of describing how to apply plaster to walls, watch this video which walks you through every step of the process. Have a look and give it a go. You probably won’t be perfect the first time you try it, but with a little time and some practice, you’ll achieve great results.

And now you’re ready to begin!
