Fixing Plasterboard to a Wall Step by Step

After you’ve measured your walls’ height and width and calculated your square footage, you should have the sheets of plasterboard and other supplies to start the project. For a standard stud timber wall, follow these steps for the best results.

  1. First, measure your walls. Take these measurements and mark your plasterboard with where you need to cut. Try and use a full sheet to start, and then cut pieces down to fit as needed.
  2. Using your utility knife, score the front paper of your plasterboard. Then, fold the section back to get a clean cut through the plaster. Cut the remaining paper with your knife. Even cuts will help you match up sheets neatly.
  3. Take your first sheet and set it next to the timber wall. Use an offcut to keep your plasterboard just off the floor. This gives the plasterboard some clearance, allowing allow for floor expansion behind your skirting boards.
  4. Adjust your plasterboard so it is resting snugly against the wall in position. Nail or screw it into place on every stud. Make sure to fasten at the edges of each sheet as well as in a line down the stud for a secure connection that will last. Repeat the process for each plasterboard sheet until your walls are securely covered.

Your Top Questions About Fixing Plasterboard Answered!

Now, you know how to go about fixing your plasterboard. But you might still have questions about what else you can do with your plasterboard. Don’t worry, we are here to help! We’ve compiled some of the most common questions about plasterboard to help you handle the installation — and help you feel prepared for the next steps!

Can You Fix Heavy Items to Plasterboard?

Yes, you can fix heavy items to your new plasterboard. But in the interests of keeping your items safe — and to prevent ruining your hard work, you need to do it right.

Heavy items cannot be fixed to plasterboard with ordinary screws or nails. You also can’t use regular wall plugs. These plastic plugs usually expand to fit the hole when you put them into a surface.

Plasterboard is a soft material, meaning that a plug’s expansion just makes the hole bigger and less likely to hang on to your heavy item. One day you may walk into your room and find your mirror or shelf has fallen to the floor and damaged the plasterboard too.

Instead, we recommend using a special plug that gives you extra staying power. Look for fixings that have a spring or toggle option. Commonly made out of a strong plastic or metal, they have wings that expand once installed. They are inserted flat into a predrilled hole so your plasterboard won’t need patching. It holds onto the other side of your plasterboard and disperses the weight of your heavy item so it’s sure to stay.

Fixing a TV to a Plasterboard Wall – How to Correctly Fix Your TV to The Wall

A wall-mounted TV is a great solution for space and viewing comfort. But you might be wondering what you need to know before fixing your TV to your walls.

First, consider the wall you want your TV to sit on. Make sure there are no pipes, wires or cabling buried behind the wall’s surface. Running into any of these items can cause some major and expensive damage, so it’s best to check before you drill into your plasterboard.

Next, you’ll need to ensure you have the right bracket. It needs to be able to hold up the size and weight of your TV. You won’t want to become a horror story and have your TV fall down and get smashed up against the ground.

To fix your bracket on a timber stud wall, find studs and screw your TV bracket into these for a strong grip. For plasterboard that has been fixed over masonry, you will need to use long enough screws or bolts that are graded for use in bricks. They will use the surface behind to anchor the weight.

If you still don’t feel confident in your ability and don’t want to be responsible for getting it right, you can always submit a free request for a plastering or TV mounting professional who will use their expertise to get your project done right!

Can You Fix Plasterboard to Brick?

Plasterboard can absolutely be fixed to brick surfaces, but it does require different steps than fixing it to timbers. This is where some of the optional materials listed above will be useful.

Your first step is to prepare the brick surface. Painted or natural surface bricks will need to be sanded for a rough surface that’s receptive for fixing. Run your hand over them to ensure no stray pieces of brick are sticking out that could damage the underside of your plasterboard. After sanding, wipe them down with a damp sponge to remove any dust that could interfere with application.

There are two methods of fixing plasterboard to masonry.

With the first, you apply stud adhesive to the bricks and stick your plasterboard to it. This is a lot like pasting a piece of paper to another surface! Use enough adhesive that your plasterboard sticks but not so much that it cannot dry.

In the second, you need to apply the wooden furring strips to your masonry using screws and plugs graded for masonry work. These should be spaced approximately 40 to 60 cm apart, about the same distance as timber studs are spaced. The furring strips give your screws something to grab onto to keep your plasterboard up. Make sure you are using screws that are long enough to reach the masonry behind for the best results.

Can Plasterboard be Fixed to a Ceiling?

Plasterboard is the perfect way to start finishing a ceiling! Use a plasterboard lift to help raise up sheets of plasterboard to the height you need, and then use traditional screws as you would with a timber wall.

Fixing plasterboard to a ceiling can be a bit more difficult since you are working over your head. If you think manoeuvring large sheets into place is going to be too much of a challenge, you can always enlist the help of a pro.

What is One Coat Plaster 

What is One Coat Plaster?

One coat plaster is a particular kind of plaster created to offer a simpler approach to plastering. It allows for application with fewer steps since this plaster acts as base and finishing coat in one. It’s also a thicker consistency that allows for thicker layers than with other types of wall plaster. 

Made up of the traditional gypsum material, the powder is mixed with the right proportion of water to create a workable consistency. This can be applied with traditional plastering tools, but this type of plaster does not need a scratch coat as your base layer. This will shorten the time of application considerably!

One coat plaster can be applied in thicker layers than traditional plaster, up to a recommended 25 mm thick. This allows you to build up any repair to the right thickness easily. more

Render can give your exterior walls a smooth finish or one that has more texture, so be sure to consider your options before you make a decision. Different texture patterns can make a difference in the look of your home. Some of this comes from the type of render material you are using.
