Armuralia Polished Plaster



  • Suitable for use with a range of substrates, including for external use in sheltered locations in a limited range of colours.
  • For application to plastered or rendered masonry such as block, brick or concrete, taped and skimmed boards such as plasterboard and GRG (glassfibre reinforced gypsum), plasterboard surfaces prepared with Armourcoat Anti Crack skim coat, single sheet 18mm primed MDF and on previously decorated (but not papered) surfaces.
  • Not suitable for application to substrates with high water content.

Materials and number of coats:

  • On unprepared plasterboard: Armourcoat Anti Crack Skim Coat Plaster (typically 3–5 mm) applied by trowel.
  • Where surfaces are of uneven suction: One coat Armourcoat K40 Primer by brush or roller.
  • Where surfaces are not uniformly flat or smooth: Two coats Armourcoat K149 Fine Keycoat (each typically 0.5 mm) applied by trowel over primer.
  • Topcoat: Two–three coats Armuralia (approximate total 1–1.5 mm).


Proprietary multicoat self-finishing plaster system, with a silk texture and subtle tonal variations.

Partly self-polishing when trowelled, the system is water vapour permeable and suitable as a finish for traditional plastered masonry, including historic buildings.

  • Applied coating, for higher sheen or increased protection against soiling: White wax or black wax.
  • Applied coating, for breathable water repellence, frost resistance, mould inhibition: Armoursil.

Features and benefits:

  • Pencil hardness to ASTM D 3363: 5H. Surface hardness increases with age and carbonation of the material.
  • Impact resistance to ASTM D 2794: Two-inch pounds.
  • Shore D hardness when tested using Elcometer 3120 Shore Durometer D: 78.
  • Mould and mildew resistance. Tested to ASTM D 3273 and ASTM D 3274.
  • VOC content to ASTM D3960 of 22 g/L.
  • Non-Newtonian thixotropic paste viscosity 85 000 cP ± 20 000 cP.
