What is Knauf Plasterboard?

Knauf Plasterboard is a gypsum-based drylining solution that comprises a gypsum core sandwiched between facer and backer paper. Popular as an alternative to wet plaster, Knauf plasterboards offer versatility, ease of use and thermal conductivity properties.

The Knauf range features different boards for different purposes, the colour of the board is a guide to their purpose. For example, the Knauf Wallboard is an ivory paper-faced plasterboard, whilst the Knauf Moisture Panel is turquoise. The standard size of board available is 2400mm x 1200mm (8” x 4”), although we do sell smaller boards for specialist applications. 

Knauf plasterboard is manufactured by Knauf Drywall, one of the UK's leading manufacturers of high-quality plasterboards, plaster and drywall systems. With a reputation for excellence, Knauf is considered one of the best brands of plasterboard available on the market.

Where Is Knauf Plasterboard Installed?

  • Partitions
  • Linings
  • Ceilings


Knauf Wallboard is the standard product within the Knauf range; this standard plasterboard boasts an ivory paper face which is ready to receive a plaster finish or painted finish (plasterboard sealer is required prior to painting plasterboard).

Knauf performance boards are understandably a little more expensive than the standard board, with various different facings imbuing the boards with enhanced properties, such as: 

  • Adding to the fire rating of a building (Knauf Fire Panel)
  • Helping with sound-proofing (Knauf Soundshield Plus)
  • Improving vapour-resistance (Knauf Vapour Panel) 
  • Increasing the moisture resistance in a bathroom or kitchen setting (Knauf Moisture Panel)


How Do I Cut Knauf Plasterboard?

One of the reasons for Knauf plasterboard’s enduring popularity is that it is surprisingly easy to modify and cut to size. 

If you need to cut Knauf plasterboard, there are two different ways you can go about it; you can either use a sharp knife (stanley knife) or a saw.

  1. Cutting Knauf Plasterboard With a Knife: If you're using a knife, score the line you want to cut first. Then, place the board on a flat surface and apply pressure to the scored line with your knife. Slowly and carefully run the knife along the line until you've cut through the entire board.
  2. Cutting Knauf Plasterboard With a Saw: If you're using a saw, make sure that it's sharp before you start. Then, follow the same steps as above - score the line you want to cut and place the board on a flat surface. Apply pressure to the scored line with the saw and slowly and carefully run it along the line until you've cut through the entire board.


The plasterboard can also be scored and snapped, so no need for specialist tools required which means rapid installation; just use a knife and a straight edge! 

Frequently Asked Knauf Plasterboard Questions

How Do I Use Knauf Plasterboard Adhesive?

Knauf plasterboard adhesive is a multi-purpose highest quality gypsum-based bonding agent that allows for the bonding of Knauf plasterboard and insulating laminates.
In order to make use of this: 

  1. First, mix 10kg of plasterboard adhesive gradually into a clean bucket containing 5 litres of clean water
  2. The plasterboard adhesive should be left for three minutes before being mixed into a smooth consistency
  3. We recommend using a power-mixing tool for mixing as long as the speed is low and the revolutions per minute are kept below 200rpm


Knauf Plasterboard: Which Side To Plaster?

The grey side is the one to plaster finish as this is the easiest side to apply the bonding adhesive and plaster to. It would still be possible to apply the plaster finish to the other side but it wouldn’t necessarily provide the same level of results. So, for the best result for your project, we recommend that only the grey side is plastered.

There is much debate in DIY forums on whether this is something that matters when it comes to Knauf plasterboard but we believe that the best results are achieved by using the grey side for the plaster finish. 

Is There An Installation Guide For Knauf Plasterboard?

As a company, Knauf is excellent at providing support for all of their products and they have various comprehensive guides available on their very informative website. If you get stuck on how best to proceed with your project we would highly recommend that you take a look at their comprehensive series of guides as we are sure you will find the answers you are looking for there.

To ensure the best performance, use in conjunction with Knauf jointing compounds, finishes, fixings, plasterboard adhesive and metal systems.

If you are storing the boards for some time before installing, ensure that boards are stored flat and protected from inclement weather.
