- Direct plasterboard bonding to brick, block, or concrete masonry
- Securing metal furring channels to masonry substrates
- Internal wall lining and partition work
- Accommodating service runs (pipes, cables) up to 25mm depth
Preparation and application
Prepare the masonry surface by removing loose material, dust, and debris. The wall should be sound and reasonably dry. Mix the adhesive according to manufacturer instructions to achieve a workable consistency. Apply the adhesive in dabs directly to the back of the plasterboard or to the masonry surface using a trowel or comb. Space dabs at approximately 300mm centres vertically and horizontally. Position the board and adjust as needed before the adhesive sets. Press firmly to ensure good contact and remove excess adhesive from joints.

- Apply adhesive in dabs at 300mm centres
- Position and adjust plasterboard before adhesive sets
- Press firmly for full contact across the board face
- Allow adequate curing time before decorating or further work
Substrate compatibility and limitations
This adhesive bonds effectively to the majority of masonry backgrounds including brick, blockwork, and concrete. However, always check that the substrate is sound and not subject to rising damp or excessive moisture. Do not apply to painted, glazed, or heavily contaminated surfaces without appropriate preparation. The product accommodates background irregularities and service runs up to 25mm; deeper voids or severely uneven walls may require furring out or alternative methods.
