Damp-proof plastering mortar with a smooth, gray industrial finish


The same damp-proof plastering mortar as Protech White, finished in gray — for the smooth industrial look, inside or out, without a coat of paint over it.

Use it for

  • Exterior walls where an exposed gray finish is wanted
  • Interior industrial and loft-style finishes
  • Levelling imperfections up to 2 mm
  • Walls exposed to heavy rain

Why this one

  • Built for the gray industrial look
    Smooth, ultra-fine gray finish that can be left as the final surface
  • Keeps the rain out
    Better resistance to water penetration than ordinary plastering mortar
  • No primer required
    Goes straight onto any plastered surface and takes any masonry paint
  • Resists hairline cracks
    Formulated not to shrink or sag as it cures
  • Just add water
    Dry-mixed and ready — no site batching of sand and cement
  • Paint after 24 hours
    Or leave it exposed. Non-toxic, good workability
