gräfix 687
Coarse mineral base
Mineral primer with grit, based on high-quality water glass, for interior and exterior use
gräfix 687 is a high-quality primer based on water glass that is very well suited for priming silicate-bound finishing plasters and silicifiable substrates. The primer creates a non-slip substrate and regulates the absorption behaviour.
The dried primer silicifies with the substrate, is particularly breathable and has a high water vapour permeability.

gräfix mineral paints
gräfix mineral paints based on silicate and lime for interior and exterior use
High-quality silicate paints in accordance with VOB/C DIN 18363 Para. 2.4.1. for the protection and design of facades - for a healthy interior design - for a natural exterior design - with special diffusion openness based on high-quality water-based glass.
The combination of selected inorganic colour pigments, mineral fillers and high-quality water glass gives gräfix mineral paints an extremely high protective function and durability to protect and preserve the building fabric. With great expressiveness, the lightfast colour pigments remain permanently stable and achieve an extraordinary depth of colour.
Thanks to the high pH value, biocidal and fungicidal additives as well as preservatives can be completely dispensed with. The gräfix mineral paint system works in a natural way against the formation of mould spores and ensures bacteria-free wall surfaces. Ideal for interiors and pollutant-free indoor air.
