SURFACE 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.
* Refer to the specific product data sheets
MIXING
- 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
