Substrates

Suitable For:

• Clinker, brickwork, stone etc
• Old masonry erected with weak mortar
• Masonry coated with traditional mortar conforming to BS EN 459-1

Unsuitable For:

• Masonry constructed with a gypsum based mortar

Technical Characteristics

Composition

• Binder: hydrated lime and specific binder resistant to salts (sulphates, chlorides, nitrates).

Lime/binder ratio = 55% minimum by volume

• Particle size: 0-1.6 mm
• Light mineral additives
• Organic additives: less than 0.3%

Performance

• Occluded air: 29.5%
• Water retention: 95%

Hardened product

• Density (g/cm3): 1.2
• Compression strength (Mpa): 3.10
• Rc / RT: 2.6
• Capillarity (g/dm2/m1/2): 0.35
• Diffusion of water vapour: 9
• Resistance to salts (days): >28

All of the above-mentioned values are average results of standardised laboratory procedures.

Instructions

Substrate Preparation

• Completely remove existing renders, rake out joints (to approximately 30 mm depth)
• Systematically clean and dry the substrate
• Treat any rising damp (for example with 232 PARINJECTION*)
• Masonry that is saturated with water must be dried out before being covered
• Repairs with PARLUMIERE STH must be carried out a minimum of 7 days before applying a top coat finish
• The application of an approved galvanised (internally only) or stainless steel reinforcement mesh may be necessary depending on the type and condition of the masonry

Note:

PARLUMIERE STH does not stop all, but it slows down the migration of salts and their appearance on the surface.

A long term solution is only possible after completely removing all causes of rising damp.

Equipment Required

Manual application: stainless steel trowel/float.

Mechanical application:

Product Preparation

• Water dosage: 5.4-6.25 litres per 25 kg bag
• Machine mixing time: 5 minutes
• Cement mixer mixing time: 5 – 7 minutes

Application

Suitable For

• Machine or manual applications

• Mortar should be applied to both sides of the wall
• First fill the joints, then when the mortar is dry, apply the base coat to an even depth of 20 mm
• Smooth and compact with a notched rule. The surface should be left with a roughend surface if receiving a decorative covering or float-smoothed if left as a final finish
• Height of application: minimum 1 m above signs of damp

Finishes

• Drying time before covering PARLUMIERE STH: 7 days minimum
• PARLUMIERE FIN*, PARLUMIERE MOYEN*, PAREXAL*: can be applied as a decorative layer of 5 mm plus a textured finish for sprayed finishes or a layer of 7 – 8 mm before float-smoothing or after scraping
• CALCIDECO*: 5 mm depth of covering

Consumption

These values are provided as guidance only and may vary subject to substrate conditions and thickness applied.

• 1.8 – 2m2 @ 10mm per 25kg bag.

Precautions

• Product intended for professional use.
• Protect fresh renders from running water, wind, sun, rain etc with a tarpaulin or draught stopper netting.
• Do not apply to a frozen substrate or if there is a risk of frost.
• Minimum application temperatures: +5°C. Over 30°C, special precautions must be taken.
• If treating rising damp, check drying time needed before covering.
