Properties and Benefits: Renosil Coarse is a ready to use, breathable exterior mineral based paint. Renosil works by chemically bonding to the surface, which results in superb durability. Renosil is not classified as an ASF paint, however it does have the ability to chemically bond to old firm painted surfaces and external insulation systems (unlike Beeckosil). This chemical bond, re-mineralises the surface, offering further protection and longevity. Renosil also contains a hydrophobic element, which can reduce water ingress by up to 90%, whilst still maintaining a vapour permeability.
Coarse contains the addition of a marble dust, which can cover / hide minor surface defects or hairline cracks and also prevent existing coatings from showing through/standing out.
Renosil Coarse can only be used as a base coat and finished with Renosil Fine. Please see our Renosil System application guides.
