One Coat Lime Plaster is straightforward, no-nonsense, consistent, labour and time saving product. One Coat Plaster doesn't require an initial base coat. Applied as normal it can be finished to smooth surface. With no waiting for a first coat to go off, this makes it faster to apply so more wall area can be completed in a day, making One Coat the perfect product, especially for smaller projects where it's not possible to use ‘waiting time' to work elsewhere.

One Coat Lime Plaster can be used on a wide range of substrates including standard plasterboard, masonry, brickwork and fibre insulation panels, which can then be painted over. One coat is the perfect finish for Steico Therm and can be applied directly to the board for internal wall insulation applications.

Just as with our other lime plasters, One Coat is highly permeable to water vapour and so allows moisture to escape while also creating a healthier living environment.

Guidance notes

  • Sample trials should always be carried out to assess compatibility with substrate.
  • Porous backgrounds should be dampened before application. 
  • Do not allow Lime green one coat plaster to rapidly dry; dampen very dry backgrounds and do not force dry. 
  • Do not prime walls with PVA 
  • Not suitable for excessively wet or continuously damp backgrounds 
  • Lime green plaster should be applied to uniformly flat walls. Uneven walls should dubbed out using lime green Duro first


  • Mix with only clean water for between 3 to 5 mins. Add approx 5-7 litres of water to a 25kg sack
  • Temperature: 5˚C to 30˚C
  • Reworking: Not possible
  • Required thicknesses
  • Insulation boards typically 8 to 12mm
  • Plaster boards typically 3 to 5mm
  • Masonry typically 10-12mm


On masonry

Apply the plaster in either one pass and level the plaster with a straight edge, leave for approximately 1½ hours. Sponge float giving a light creamy texture to the plaster, leave for another few minutes after which the plaster may be closed in with a steel trowel to produce a smooth finish. Do not over work the surface or this may lead to fire cracking.

On boards and wood fibre insulation boards.

Apply Lime Green one coat plaster in 2 passes within one hour of each other with lime green 910 mesh pushed into the first pass

Finish the plaster as above
