What is Knauf Plasterboard?

Knauf Plasterboard is made from calcium sulfate dihydrate, (gypsum), which is often made using stucco or plaster of Paris, which is then sandwiched between a facer and backer paper. Plasterboard is a very popular product that is used an as alternative to wet plaster. Since its introduction, it has been widely adopted due to its versatility and ease of use, there are also thermal conductivity properties as well.

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, or the Knauf Moisture Panel is turquoise. 

Knauf plasterboard is manufactured by Knauf Drywall, who have a whole plant in East Lincolnshire dedicated to the continuous production of Knauf plasterboard, with around 480 employees in the UK. With a reputation for excellence, Knauf is considered one of the best brands of plasterboard available on the market.

What is Knauf Plasterboard used for?

Strength and versatility are words that describe Knauf plasterboard very well and it is these properties that make it one of the most popular building materials in the UK and worldwide. There are a myriad of uses for Knauf plasterboard and some of the most popular are as partitions between different rooms, linings and ceilings. Knauf Wallboard is the standard product within the Knauf range, which has an ivory paper face, which is ready for a plaster finish or for direct decoration.

The various different facings that can be given to Knauf Plasterboard imbue it with enhanced properties and this makes it an even more desirable material as it can be used to add to the fire rating of a building (Knauf Fire Panel), to help with sound-proofing (Knauf Soundshield Plus), to improve vapour-resistance (Knauf Vapour Panel) or to increase the moisture resistance in a bathroom or kitchen setting (Knauf Moisture Panel). Boards with these properties already in place would be referred to as “performance boards” and are understandably a little more expensive than standard Knauf Plasterboard.

How do I cut Knauf Plasterboard?

One of the things that we as a major Knauf plasterboard supplier often get asked is “how to cut Knauf plasterboard”. One of the reasons for Knauf plasterboard’s enduring popularity is that it is surprisingly easy to modify and cut to the size that is needed for the job. There are dedicated saws for cutting this as the density and strength of Knauf plasterboard means that it can blunt a normal saw pretty quickly. If you have a big job involving Knauf plasterboard, it makes sense to get one so you have the right tool for the job.

Next, you should measure the opening in the board that is needed and mark it off in pencil. If you are cutting a circle in it, you should use a plasterboard hammer 50mm inside one of the lines you have drawn in a short, swift movement in order to open up a space to insert the plasterboard saw. It is then simply a case of cutting your shape with the saw, as you would using any other material. It is possible to smooth the edges with a plasterboard plane and to seal the new edges with decorators caulk.

The plasterboard can also be scored and snapped, so no need for specialist tools required which means rapid installation.

Frequently Asked Questions about Knauf Plasterboard

How do I use Knauf Plasterboard adhesive?

Here at Materials Market we often get asked how to use Knauf plasterboard adhesive. This 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, you need to mix 10kg of plasterboard adhesive gradually into a clean bucket containing 5 litres of clean water. At this point the plasterboard adhesive should be left for three minutes before being mixed well until the texture is smooth. A power-mixing tool would be ideal for this part of the job as long as the speed is low and the revolutions per minute is kept below 200rpm.

Knauf plasterboard: Which side to plaster?

This is another frequent question about Knauf Plasterboard and as one of the places that you can find Knauf plasterboard cheapest on the internet, we are happy to oblige with an answer for you. The grey side is the one that have the plaster finish as this is the side that is easiest 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?

People who are new to installing Knauf plasterboard and are looking for assistance in getting started on their project will no doubt seek guidance on how to install it. We unfortunately don’t have the room here to produce a full installation guide and have no wish to reinvent the wheel as the manufacturers themselves provide excellent installation guides already.

As a company, Knauf is very good 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 top performance, use in conjunction with Knauf jointing compounds, finishes, fixings, plasterboard adhesive and metal systems.
