Description
Quick answer: Plasterboard bonding adhesive is a 25kg gypsum-based adhesive used for fixing plasterboard to masonry and other suitable internal backgrounds. It is designed for dry lining work, not for skimming, jointing, filling, external use or areas exposed to moisture.
What is this used for?
This plasterboard bonding adhesive is used for fixing plasterboard directly to suitable masonry walls and internal backgrounds. It can also be used for fixing metal furring channels before plasterboard is installed.
It is a practical choice for internal dry lining projects where plasterboard needs to be bonded to a suitable wall surface rather than fixed to timber or metal studwork with screws.
Is this the right product for your project?
Choose plasterboard bonding adhesive when you are dry lining an internal wall and need to bond plasterboard to a clean, sound and suitable masonry background. It is commonly used for dot-and-dab style plasterboard fixing and other internal wall lining work where adhesive fixing is appropriate.
This is not a finishing plaster, jointing compound, filler, tile adhesive, external render or general-purpose building adhesive. If you are fixing plasterboard to timber studwork or battens, suitable drywall screws will usually be the correct fixing instead.
What does bonding adhesive mean?
Bonding adhesive is used to attach plasterboard to a suitable background. It is mixed with clean water and applied by hand using standard plastering tools.
Once mixed and applied correctly, it provides a bond between the plasterboard and the wall surface. The final result depends on proper mixing, background preparation, application method, board positioning and setting time.
Coverage guide
The product page states an approximate coverage of 4–6m² per 25kg bag. Coverage can vary depending on the wall condition, background, application method and how much adhesive is needed to bring the boards level.
Uneven walls may use more adhesive, so allow extra where the background is rough, out of plumb or inconsistent.

Things to check before ordering
- Background: The wall must be suitable, clean, sound and prepared before adhesive is applied.
- Internal use: This adhesive is for internal dry lining work, not external applications.
- Moisture exposure: Do not use where the adhesive or board system will be exposed to direct or continuous moisture.
- Fixing method: If you are fixing plasterboard to timber studwork or battens, use suitable drywall screws instead.
- Coverage: Allow extra adhesive if the wall is uneven or needs more material to level the boards.
- Mixing: Mix with clean water and follow the manufacturer guidance for preparation and application.
- Setting time: Allow adequate setting time before carrying out further work.
- Storage: Store bags in a dry place and protect from moisture before use.
Complete the job
For dry lining work, you may also need plasterboard sheets, scrim tape, angle beads, finishing plaster and other plastering products. If you are mechanically fixing plasterboard rather than bonding it, use suitable drywall screws.
