Features & Benefits

Parinter Renovation’s composition and adhesion properties make it compatible with a large number of non-porous or smooth substrates (painted surfaces, hydraulic renders or concrete).

Suitable Parex finishes that can be applied onto Parinter Renovation:

• Decorative coatings:
  • Calicane Badigeon
  • Silicane Peinture
• Decorative finishes:
  • Calcideco
  • Cacilisse
  • Calcifin
  • Silican Taloche range of finishes
• Decorative renders:
  • Monorex GM
  • Monorex GF
  • Monoblanco
  • Monomax
  • Monomax Blanco
  • Parexal
  • Parlumiere Clair
  • Parlumiere Moyen
  • Parlumiere STH

Unsuitable finishes that MUST NOT be applied onto PARINTER due to their higher mechanical strength (they could delaminate):

• Parmurex
• Blanc Du Littoral
• Monodecor TL

Suitable For:

• Sound rendered masonry including those with a thin paint coating <300 µ (pliolite, acrylic based coatings) or with a thick acrylic covering which has passed preliminary bonding tests. Refer to the Preliminary Identification and Bonding Tests section of the Product Data Sheet
• Sound concrete
• Brick and block masonry
• Sound and well bonded Sandstone or Terracotta tiles
• Always carry out preliminary checks of the substrate and prepare thoroughly in accordance with the technical specification information

Unsuitable For:

• External insulation systems
• Substrates covered with:
  • Thick acrylic coverings that are painted with a water repellent-treatment
  • Several layers of paint or thick acrylic coverings
  • Un-sound paint or where multiple layers of paint have been applied and are de- bonding
  • Mineral paint e.g chalk based whitewashes, silicates or silicate-treated thick acrylic coverings
  • Semi-thick gloss or flexible glycerol paint
  • Impermeable and/or flexible coatings
  • Water repellent surfaces or those with anti-graffiti coatings
• Exposed substrates with a vertical incline above 10° - a backward incline may affect water run off and may have a tendency to hold moisture
• Substrates with rising damp, or where the walls are continually wet or damp

Preparation

• With a render that is painted or has a thick acrylic covering, carry out preliminary identification tests to check compatibility with Parinter. Refer to the Preliminary Identification and Bonding Tests section of this data sheet
• If the surface is compatible, wash under high pressure (140 bars) with a rotating nozzle and allow to dry for 48 hours
• If the facing is incompatible, it must be completely removed before application
• Carefully powerwash and brush to remove dirt and grease, algae, dust and any other loose materials that will affect adhesion
• If required apply a fungicidal wash using 251 Lankomousse
• Check soundness of the render and remove all loose material, powdered and hollow-sounding parts
• Treat and repair damaged areas with Monogris E, Tradirex, Parlumiere Clair or Parlumiere STH depending on the substrate or as guided on the Parex specification
• Remove any uneven surfaces or projections that may affect the surface finishes

Application

• The application of Parinter may require 1 or 2 coats, depending on the condition of the substrate, with or without TV10 Mesh embedded in the first coat. The substrate must be sound and not de-bonded
• Where there are different substrates they must be isolated from each other and the joint treated with acrylic mastic Parex Joint Acrylique
• Carry out the finish on substrates which have dried for a minimum of 24 hours
• Thickness of application without TV10 Mesh: 3 to 5 mm
• Thickness of application with TV10 Mesh: 5 to 8 mm
• Time before covering: 24 minimum to 48 hours maximum
• Thickness of decorative renders: 10 - 13mm (10 mm after scraping or 8 mm plus decorative textured finish – Tyrolean or or Spray Textured effect)
• Thickness for decorative coating: 5 to 8 mm
• Coverage:
  • Smooth substrate: 5 - 8 kg/m2 (3.75 - 6m2 per 30kg bag) for 3 to 5 mm thickness
  • Rough substrate: 8 - 13 kg/m2 (2 - 3.75m2 per 30kg bag) for 5 to 8 mm thickness

*These measures spread the stress of the fracture, but there is still a risk of cracking if the substrate continues to move.

**Refer to the specific product data sheets.

Limitations

• Product intended for professional use
• Due to the potential of heat absorbtion created with dark colours, the colours of the finish must not exceed solar absorption coefficient over 0.7 (0.5 in mountainous areas)
• It is advisable when completing the different finishes, to take into account the hardening time, which will vary according to climatic conditions
• Avoid applications on substrates exposed to direct sun or in hot drying winds
• In hot conditions dampen the substrate prior to application. Dampen the render after application
• Do not apply to a frozen substrate or on thawing substrates. Do not use in freezing conditions
• Take precautions during damp climatic conditions. Discolouration could occur)
• Do not apply on very wet substrates or where there are wet patches. (Discolouration could occur)
• Minimum application temperatures: +5°C for light colours, +8°C for dark colours
• Over 30°C, special precautions must be taken
