  • Well ventilated areas exposed to moisture, but not suitable as a waterproof finish.
  • Existing painted walls and ceilings provided the paint is well-adhered to the substrate.
  • Direct application to any stable, firm substrate that is ready for decoration such as plastered or rendered masonry (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.


  • Substrate must adhere to a tolerance of +- 1 mm/600 mm or +-3 mm/1800 mm.
  • Not suitable for papered surfaces.
  • Also available on pre-manufactured, ready to hang panels.


Materials and number of coats:

  • Plasterboard substrates to be prepared with gypsum skim coat and sealer or taped, jointed and sealed by others.
  • On unprepared plasterboard: Armourcoat AntiCrack skim coat plaster (typically 3–5 mm) applied by trowel.
  • System build-up comprising four-five coats (approximate total thickness ~1.5 mm).

Description

Armourcoat SMG is a natural lime and marble polished plaster with an ultra smooth surface that gives a seamless, high gloss lacquer effect. It is a superfine, highly reflective finish with little or no surface movement.


The lime plaster is water vapour-permeable and as such is suitable for traditional plastered masonry, including historic buildings.


It comes with Eco Wax (or black wax for deep tones) applied as standard for increased protection against soiling. For breathable water repellency, specify with Armoursil Impregnator + Aquawax.


It is also available to be used as a system with Armourcoat® AntiCrack reinforced gypsum skim coat. Please see specification data for more details.
