Consolidante Silicato de Etilo

Esters in the silicic acid react with atmospheric humidity  and become silica gel and ethyl alcohol. The polycondensation reaction may be summarised as follow: [Si(OEt)4]n + 2 nH2O • nSiO2 + 4n EtOH.
Silica gel, thanks to its great chemical union with the substrate, provides the surface with new mechanic properties.

Features and applications

CONSOLIDANTE SILICATO DE ETILO can be applied on natural stones of silicic and carbonic nature, bricks and terracotta...

Instructions for use

  • CONSOLIDANTE SILICATO DE ETILO (Ethyl Silicic binder) is a ready to use product. Suitable for absorbent mineral substrates.
  • The  treated surface should be dry, cured and clean, free from efflorescence salts.
  • The product can be applied by immersion when it comes to spare pieces, or using paintbrushes or using a spray gun of low pressure (0,5 maximum) on claddings.
  • According to the type of material treated, we should always consider whether an application of the product until saturation in the substrate is adequate , or a partial priming , always assuring  we have reached the healthy nucleus of the substrate.
  • It is essential to carry out preliminary tests in order to verify:
    • The degree of consolidation or reinforcement achieved.
    • The yield of the product (generally between 0,5-3.0 l/m2)
    • The lack of chromatic variations on the treated material.
  • CONSOLIDANTE SILICATO DE ETILO (Ethyl Silicate binder) completes its reaction after 28 days approximately ( 20ºC temperature and relative humidity of 40-50%)

Cautions and recommendations

  • Room temperature should be between 10ºC and 25ºC.
  • The treated surface should not be exposed to direct sun radiation.
  • Protect the treated area from rain water for at least 7 days after its application.
  • In case  of applying an excess of product, it is possible to remove it, before its hardening,  using  compresses soaked in  mineral organic solvent (White Spirit, Ras Mineral, etc.)
  • Make sure the packaging is properly closed between applications, as the product may react with atmospheric humidity.

Consumption according to dimensions (kg/m²)

Varies  according to the product purpose. Generally  between 0,5L and 3L/m2


5 L and 25 L containers.
