Sikagard 680 S is a one part, solvent containing coating, based on methacrylic resins resistant to weathering, alkalis and ageing. It is available in clear and coloured grades for use on mineral substrates including concrete and other cementitious surfaces.

Sikagard 680 S protects concrete against aggressive atmospheric influences and promotes a self-cleaning effect on the treated surfaces. It does not adversely influence the characteristic texture of the concrete. Sikagard 680 S complies with the requirements of EN 1504-2 as protective coating.

Available in 14 RAL colours - other colours may be available, please contact us with your requirements on 0113 2455450 (option 2) or send a message to [email protected].

  • Due to its quick drying properties, the coating is rain resistant within a short time
  • Almost no change in the texture characteristics of the concrete surface
  • Sikagard 680 S protects the concrete against aggressive atmospheric influences, which can penetrate into the concrete in the form of salts or gases
  • Very high diffusion resistance against carbon dioxide and, therefore reduces considerably the rate and depth of carbonation of the concrete
