Application steps

EQUIPMENT

  • Manual application: stainless steel trowel/float.
  • Mechanical application:

    MECHANICAL APPLICATION

    SPRAY RENDER MACHINE

    		SPRAYING POT

    Pump pressure

    6 – 8 bars (water)

    Air flow

    60 m3 per hour minimum

    Air pressure

    4 – 6 bars

SURFACE 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.
 

NB:
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.

MIXING

  • Machine mixing time: 5 minutes.
  • Cement mixer mixing time: 5 – 7 minutes.

APPLICATION

  • 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.
  • 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.
