KEIM Royalan Grob is a highly filled primary coat
and filler for the KEIM Royalan system which reacts
chemically with the surface.

bridging coat on previously painted surfaces or to
bridge hairline cracks and equalise the surface.
KEIM Royalan is formulated for use in extreme
climatic conditions.
The KEIM Royalan system offers water repellency,
vapour permeability and forms a chemical bond
with the mineral substrate. KEIM Royalan Grob is
made using pure inorganic mineral fillers, lightfast
inorganic pigments, additives, potassium silicate binder and glass fibres.
