Fixopierre

Fixopierre is a water vapour-permeable and microporous substrate porosity regulator and key coat admixture. It is 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.

Applications:

• Substrate regulator: Depending upon substrates porosity dilute with water to concentration between 10 and 50%. Apply by brush, spray or roller.

• Bonding coat: (In small areas) make up a bonding coat of mortar and Fixopierre diluted with 20% water approx. to obtain a fluid consistency. Brush onto surface.

• 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 render to adhere well.
