Suitable Substrates

• Suitable for:
  • Pisé, rammed earth, adobe, cob, witchet, clinker
  • Old masonry constructed with weak mortar
  • Masonry with plaster or lime mortar pre-treated with Gobetis Special A
  • Masonry coated with traditional mortar conforming to BS EN 459-1 or BS EN 13914-1
  • One-coat weather-resistant mortar, including Parex grey weather resistant base-coats
  • New masonry construction e.g. Concrete or aircrete blockwork
• Unsuitable for:
  • Pure hydrated lime or plaster coatings, paint, thick acrylic painted coverings - unless coated with Parinter renovation mortar (Refer to specific requirements on the Parinter data sheet)
  • Lightweight hydraulic coats with lower mechanical strength than Parlumiere Clair
  • Exposed horizontal substrates with a vertical incline above 10°- a backward incline may affect water run off and may have a tendency to hold moisture

Substrate Preparation

• Substrates must be clean, sound and dust-free
• Treat capillary rise in walls (for example with 232 Parinjection)
• Check soundness, remove all loose material e.g. paint, synthetic coverings, plaster
• Rake out joints to a depth of 2 to 3 cm
• All repairs must be carried out a minimum of 7 days before application
• Spray with water (except earth-based substrates) the day before until saturated, but not so that wall is running with water. Repeat prior to application, ensuring that substrate is wet through
• Water dosage: 4.6 – 5.6 litres per 25 kg bag
• Machine mixing time: 5 minutes
• Cement mixer mixing time: 5 – 7 minutes

Application

• For joints between bricks and facing stones: Press firmly into joints with a trowel. Brush after drying
• Coating on old masonry — thickness 15 to 30 mm: To ensure full weatherproofing, the finished coat must have a minimum overall thickness of 15 mm and must be applied in 2 or 3 compact coats:
  • 3 coats, manual: apply the first coat or key coat 48 hours before the following 2 coats in successive compact layers
  • 2 coats, mechanical: spray a 10 mm body coat and leave to dry for 3 days then apply a 5 – 12 mm finishing coat
• Very thick coating on old masonry — thickness 50 mm maximum: Apply a minimum of 2 compact coats with a minimum 7 days drying time between each coat, according to weather conditions. For coverings between 30 mm and 50 mm, use galvanised or stainless steel reinforcement mesh
• Coating on pisé, adobe, cob, witchet, clinker — thickness 10 to 25 mm maximum: Apply 2 compact coats on to a hardened key coat of Parlumiere Clair with Fixopierre added. Never dampen earth based substrates. For additional information refer to CHAUX DE PAVIER* data sheet. Loose or mixed substrates should be reinforced with a flexible large mesh
• Coating on masonry covered with plaster mortar — thickness 15 to 30 mm:
  • Rake out joints to a depth of 3 cm. Apply Gobetis Special A and leave to dry for 24 hours. Then apply 2 compact coats, with a minimum of 3 days’ drying time between them, covering the entire substrate evenly
  • Final coat — thickness of 5 to 12 mm
  • Apply a coat of Parlumiere Clair in 1 or 2 layers (2nd layer whilst 1st is still fresh)
  • Finish as required: Spray Textured, Smooth Spray, Textured Float-Smoothed, Trowel Smoothed in natural white
• FINISHES:
• Natural white or customised on site by adding 3 litres of 2 to 5 mm sand and/or a maximum of 300 g natural colouring (soil) per bag
• The top coat finish can be created with a coating from the Patrimoine Heritage lime render range (Parlumiere Moyen, Parlumiere Fin or Parexal). Other associated coverings include Cacideco, Calcilane Badigeon, Calcilane Enduit, Calcilane Antico
• Coverage: Approx. 15 kg/m2 1.6 – 1.7m2 @ 10mm per 25kg bag

Limitations

• For professional use only
• Dampen the substrate prior to application. Dampen the hardened render after application
• Protect façades throughout the work
• Do not apply to a frozen substrate. Do not use in freezing conditions
• Minimum application temperatures: +5°C. Over 30°C, special precautions must be taken
