SILIKATBINDER

Silicate primer

  • 1-component
  • Water-borne

Water-borne, inorganic, one component potassium waterglass-based primer for mineral surfaces.

For pretreatment and priming of mineral surfaces in- and outdoors which will be painted with SILIKATFÄRG silicate paint. See data sheet 924: SILIKATFÄRG silicate paint.

Binds and reinforces brittle substrates and enhances even absorption of the top coat.

Surface preparation

NEW SURFACES: It is recommended that new plaster surfaces are coated only after a hardening time of 6 - 8 weeks. Remove all dirt, dust and other loose impurities from the surfaces by cleaning with high pressure washer, if needed. See data sheet 924: SILIKATFÄRG silicate paint. PREVIOUSLY PAINTED SURFACES: Remove flaking and poorly adherent or chalking, pulverized (e.g. lime wash) old paint coats. The method to be used is chosen depending on the strength of the substrate and the type of the paint to be removed (e.g. wire-brushing, hot pressurized-water cleaning or water-sand cleaning).

Application

Before use stir the product thoroughly. Priming is not needed on solid cement plaster, concrete or painted surfaces. Strongly absorbent porous substrates, such as plaster and surfaces painted with lime paint, are pretreated with SILIKATBINDER Silicate Primer diluted with water in the ratio of 1:1. NB! Silicate primer and paint are corrosive. Protect glass, glazed, natural stone and metal surfaces. PRIMING is done with a mixture of SILIKATFÄRG Silicate Paint and SILIKATBINDER Silicate Primer. Mixing ratio 2:1. Apply the primer by brush, roller and/or airless spray. Recommended nozzle size for spray is 0.013 - 0.017".

Application conditions

During the application and drying period the temperature of the ambient air, the surface and the paint shall be above +10 °C and the relative air humidity below 80 %. Avoid painting in direct sunlight.
