What is Tapered Edge Plasterboard?

Tapered Edge Plasterboard refers to any gypsum plasterboard that has a tapered edge rather than a square edge. These tapered edges create a small groove when the plasterboards are butted up against each other.

This groove can then be taped with scrim tape and jointed using joint filler or jointing compound. This process is known as taping and jointing, and it provides a smooth finish that can be painted over.

Tapered edge plasterboard comes in both standard and performance ranges, is suitable for direct decoration, and will comply with most building specifications.

Types of Tapered Edge Plasterboard

All standard multi-use plasterboard comes with either a square edge or tapered edge. Tapered edge plasterboards are typically sold in 1200mm widths to accommodate the 600mm stud spacing which is common in residential builds. They also tend to boast an ivory paper face which is designed to receive a plaster finish or for direct decoration. We sell a range of standard Tapered Edge Plasterboard boards, one of our popular boards being the 12.5mm Knauf Wallboard TE

Other plasterboard boards, such as those offering acoustic and fire performance, also come with a tapered edge. Some examples of this include:

Frequently Asked Tapered Edge Standard Plasterboard Questions

How Do I Install Tapered Edge Plasterboard? 

Installing Tapered Edge Plasterboard is a relatively straightforward process provided you take the necessary steps and ensure you have any potential safety hazards covered.

  1. First, set up your timber or metal partitions to create the frame of the wall

  2. Next, fix the plasterboard to the partitions. The sheets can be easily fixed using drywall screws. If applying to brick or masonry backgrounds, you can bond the plasterboard using drywall adhesive

  3. Tape the joints (this is where the tapered edges meet) using scrim tape

  4. Fill the joints using joint filler

  5. Sand the joints down so that surface of the plasterboard sheet is relatively flat

  6. Finally, paint the plasterboard for a nice finish

Note that tapered edge plasterboard can also be skimmed with a thistle plaster finish.

How Do I Cut Tapered Edge Plasterboard? 

Tapered Edge Plasterboard is super easy to cut - all you'll need is a plasterboard saw, or failing that, you can simply score with a sharp knife and snap the board over a straight edge. 


Holes for switch/socket boxes should be considered and cut out before the boards are fixed.
