gräfix 686
Fine mineral primer
Mineral-based primer without grit for interior and exterior use
gräfix 686 is a high-quality, water-glass-based primer that is ideal for priming mineral or other substrates that are not suitable for silicification.
Once dry, the primer is particularly breathable and has high water vapour permeability.
Supplied in: 5 kg and 20 kg buckets
Coverage: approx. 130–330 g/m² per coat

gräfix mineral paints
gräfix mineral paints based on silicate and lime, for interior and exterior use
Silicate paints in accordance with VOB/C DIN 18363, clause 2.4.1, for the protection and decoration of façades, and for mineral coatings in both internal and external applications. The paints are based on water glass and possess vapour-permeable properties.
The combination of selected inorganic colour pigments, mineral fillers and water glasses gives gräfix mineral paints protective and durable properties and helps to preserve the building fabric. The lightfast colour pigments ensure a striking colour effect and depth of colour.
Thanks to its high pH value, the gräfix mineral paint system requires no biocidal or fungicidal additives, nor any preservatives. The high pH value creates conditions on the wall surface that can inhibit the growth of mould. The mineral paint system is therefore particularly suitable for mineral-based wall structures in interior applications.
