British Gypsum ThistlePro UniFinish Plaster- 25kg

Weight: 25kg

ThistlePro UniFinish is a gypsum finish plaster specially formulated for re-skimming over a wide range of backgrounds with no need for pre-treatment with PVA. It provides a smooth, inert, high quality surface to internal walls and ceilings, and a durable base for the application of decorative finishes. Thistle UniFinish is a retarded hemihydrate, pre-mixed gypsum plaster, requiring only the addition of clean water to prepare it for use. Apply with firm pressure, build out to 2mm thickness in two applications and trowel to a smooth matt finish as the plaster progressively hardens through setting or by loss of water into the background.

CHARACTERISTICS
Gypsum plasters provide good fire protection due to the unique behaviour of gypsum in fire. Materials adjacent to the unexposed side will not exceed 100°C – 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.

APPLICATION
Most backgrounds encountered in re-skimming jobs will need no pre-treatment before using Thistle UniFinish,
  • Most paints, including matt, silk, vinyl, eggshell emulsions, kitchen/bathroom paint,
  • Walls stripped of wallpaper (with minimal wallpaper adhesive remaining),
  • Painted texture compounds,
  • Undercoat plaster, except if very high suction (some lime-based or sand/cement backgrounds),
  • Skim finish plaster
  • Tile adhesive
Unsuitable backgrounds include:
  • Unpainted texture compounds – these can soften significantly when wetted, leading to adhesion failure
  • Self-cleaning or anti-graffiti paints – these are often designed to not fully harden, or to have a deliberately water-repellent or weak surface layer so that materials that stick to them are removed easily, so they are not suitable for plastering
  • Surfaces where there is flaking or delamination between layers, and poorly bonded, friable or dusty surfaces – there is a high risk of failure unless such materials are removed
INSTALLATION
  • 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,
  • 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,
  • Apply in 2 coats , each coat at a minimum of 1mm thickness,
  • For the best surface finish results use a clean, damp trowel,
  • Avoid polishing and aim for a 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 Browning, except where the system includes a bonding agent.
