Gyproc Hard Coat

Gyproc Hard Coat is a gypsum undercoat plaster for use on most masonry backgrounds.  Applied in conjunction with a final coat of Gyproc Finish Plaster, it provides a smooth, inert, high quality surface to internal walls.
The combination has excellent impact resistance, quick surface drying and a high resistance to efflorescence and gives a durable base for the application of decorative finishes.
 
Key Features:
  • Superior impact resistance
  • High coverage per m²(120m²/ton @ 11mm depth)
  • Light weight for rapid application – up to 30% faster than sand & cement
  • Saving on Finish Plaster requirement – up to 30% saving
  • Fast drying for earlier painting – paint up to 15% sooner
  • Finish coat can be applied as soon as Hard Coat is set or can be wet down for later finishing
  • Air-tightness - When applied to masonry walls Gyproc Hard Coat finished with a Gyproc finishing plaster can provide a significant contribution to the overall air-tightness performance strategy of a building.  Test results undertaken in a UKAS accredited laboratory demonstrate that the application of Gyproc Hard Coat + Gyproc Skimcoat finish over 100mm concrete blocks, laid on edge, can offer an air permeability performance of 0.03m³/h.m² (50Pa)
  • No shrinkage cracking will occur with the use of Hard Coat with a Gyproc Finish Plaster, unlike sand & cement
