How To Install and Fix Plasterboard

Plasterboard can be fitted in your home in three different ways, the most relevant of which will depend on the type of substrate behind it. For example, if you are fixing plasterboard to brickwork then the best option will be to use the dot and dab technique. While if you are working with timber frames and partitioning walls, then you can use screws or nails.


In this guide, we’ll take you through how to install plasterboard in each different scenario.


How to fix plasterboard using screws

When dealing with plasterboard fixings and screws, you’ll need to be aware of where any pipes are located behind the boards to avoid accidently fixing a screw through a pipe, which would cause a multitude of problems. The ideal size of the screws that you’ll need is roughly 25mm longer than the thickness of the plasterboard.


When you’re ready to fix the boards, take the following steps:


1.     Make a note of where the timber framework is and mark lines on the plasterboard as a reminder. This is to ensure that you don’t accidentally miss the timber when you’re placing the screws in.

2.     The screws will need to be placed at gaps of 100-200mm across the timber framework. It’s important to note that you shouldn’t place any screws within 12mm of the edge of the board.

3.     Drill the screws in slowly until the head of the screw is just under the surface of the paper.


How to fix plasterboard with nails

Plasterboard can also be fixed using nails, with the size of the nails depending on the size of the plasterboard. 30mm long nails are best for 9.5mm thick plasterboard and 40mm for 12.5mm thick plasterboard.


When you’re ready to fix your plasterboard using nails, take the following steps.


1.     As with the version with screws, make sure to mark lines on the plasterboard where the timber framework is. This is so that you don’t miss the timber when hammering the nails in.

2.     Ensure that there is a gap of 150mm between nails and don’t be any closer than 12mm between the nails and the edge of the boards.

3.     Hammer the nails into board until they are securely in.

How to fix plasterboard with the dot and dab method

It is important to have plasterboard adhesive ready to go for this method, as well as having the boards cut and ready with the right dimensions for the space that they’re going in. If there are any electrical sockets that will be in the way, make sure to cut out the spaces for those in the board too, as required. Then, take the following steps:


1.     The first step is to mix the plasterboard adhesive until it is thick in texture.

2.     Then dab a lump of the adhesive spaced out around 20cm across the plasterboard, so that it leaves dots.

3.     Use a spirit level to make sure the board is straight, and line it up with the space that you will be putting it into.

4.     Press the board down firmly and make sure that it doesn’t move when you’ve taken your hands off it.


You’ll also need to make sure that you leave a gap between the boards and the floor to reduce the risk of any damp.
