Parex® FIXOPIERRE

Parex® FIXOPIERRE

SUBSTRATE POROSITY REGULATOR AND ADMIXTURE 

FIXOPIERRE is a water vapour-permeable and microporous substrate porosity regulator and key coat admixture, particularly suitable for lime or earth based substrates where high breathability of the substrate is required or where a high absorption substrate is expected. FIXOPIERRE improves the adhesion of façade renders by reducing the risk of the product drying out before hardening.

  • Microporous substrate porosity regulator
  • Key coat admixture
  • Improves the adhesion of façade renders

Usage

  • As a substrate regulator (on porous substrates: wet the substrate first).
  • Creating a key coat or bonding coat when mixed with products designed for restoration of old substrates e.g. Parex® lime range of renders.
  • Preparing substrates as a primer coat for rendering onto e.g. stone, masonry, terracotta, bare earth (cob, adobe, witchet etc), shuttered concrete, aircrete concrete, traditional or one-coat renders, decorative stones or bricks.  

Advantages

  • Microporous substrate porosity regulator
  • Key coat admixture
  • Improves the adhesion of façade renders

Consumption

This information is provided as guidance only, excludes wastage and will vary subject to the application and substrate.

  • Substrate Regulator: 0.015 to 0.125 L/m2 depending on the substrate condition and porosity
  • Key coat 0.5 to 1 L per 25 kg bag 
Application steps

APPLICATION

  • SUBSTRATE REGULATOR: depending on the substrate’s porosity, dilute the product with water in proportions from 10 to 50 % (either 1 volume of FIXOPIERRE for 9 volumes of water or 1 volume of FIXOPIERRE for 1 volume of water). Apply this solution with a brush or spray ensuring the substrate is fully coated and in order to complete the humidification process.
  • BONDING COAT: for small areas, make up a bonding coat of mortar and FIXOPIERRE diluted with approximately 20 % water to obtain a fluid consistency. Apply to substrate with a brush. The render can be applied to a dry or sticky bonding coat.
  • KEY COAT: for large areas, depending on type of substrate, directly mix in 8 to 20 % FIXOPIERRE into the mixing water for the render. Spray an even thin coat layer (no thick areas) leaving a rough surface finish to allow the renders to adhere well.
  • Waiting time before applying the render is 2 to 12 hours as a sticky substance. After 12 hours, wetting of the key coat will be necessary prior to application of the finishing layer
