Thistle Board Finish is a gypsum finish plaster for use on low to medium suction backgrounds. It provides a smooth, inert, high quality surface to internal walls and ceilings, and a durable base for the application of decorative finishes. Thistle Board Finish is a retarded hemihydrate, pre-mixed gypsum plaster, requiring only the addition of clean water to prepare it for use.

Gypsum plasters provide good fire protection due to the unique behaviour of gypsum in fire. Materials adjacent to the unexposed side will not exceed 100C below the temperature at which most materials will ignite and far below the critical temperatures for structural components. Once the gypsum layer is fully calcined, the residue acts as an insulating layer while it remains intact.

  • Bags should be stored dry, as absorption of water shortens the setting time, causes set lumps to form in the bags and may reduce the strength of the set plasterwork,
  • Skim finishing using Thistle Board Finish should be to the smooth face of the board,
  • Thistle plasters should be mixed by adding to clean water in clean mixing equipment. Contamination from previous mixes adversely affects the setting time and the strength. Fresh contamination has more effect than old, so equipment should be washed just after mixing rather than just before.
  • Plaster is applied with firm pressure, built out to the required thickness in two applications and trowelled to a smooth matt finish.
  • Gypsum-based plasterwork must always be thoroughly dry before decorating, although a coat of permeable paint can be applied in the interim.
  • Tiles up to 20kg/m2 can be applied directly to the Thistle Board Finish, except where the system includes a bonding agent.
