Granital Grob is formulated to prime previously painted surfaces, hairline cracks and variations in the texture of the surface, ready for the Granital top coat.
Having looked at Keim Granital, and determined its suitability for your project, the application of Granital Grob will be of great use to those who need to coat over previously painted surfaces, or surfaces which are textured. Granital Grob also acts as a mild filler, which gives peace of mind for surfaces which contain hairline cracks.
For highly absorbent substrates, you will need to use Granital Dilution (Spezial-Fixativ). This is a silicate-based dilution, and although it is not yet live on Rawlins Paints, you can email us for more information.
