19mm Plank is perfect for party walls and floors
19mm Plank is a thicker version of the standard wallboard. This therefore makes it the ideal choice for acoustic 'mass' layer applications such as party wall and floors.
Where and how to use them
Plank can be used for walls and ceilings.
If fixing to masonry walls, be it internal or external the usual method is to ‘dot and dab’. This means using a suitable Dri-Wall Adhesive or Bonding Compound which the boards then adhere to, keeping them firmly in place. They can also be mechanically fixed to timber battens that would be fitted to external walls.
Plank can also be mechanically fixed to timber stud partitions, metal stud partitions or metal wall lining systems.
If fixing to ceilings, mechanical fitting is the way to go. This should be done by using clout nails or drywall screws. They can be fixed to either timber joists and rafters or the metal MF ceiling system.
Once in situ, they are ready for either direct decorating, providing the correct jointing and sealing procedures have been followed or ‘skimmed’ with a suitable plaster finish such as Thistle Board Finish or Thistle Multi Finish.
