I'm about to install a Neff T44T43N0 induction hob. As the worktop is granite, preventing the retaining clips to be fixed by screwing into the worktop aperture edge, they need to be fixed to this edge with a temperature resistant adhesive. The granite fitting company has stressed the need to use one which won’t creep into the granite grain and rise as a stain under the sealed surface around the edge of the hob. However, neither they or Neff are able to advise on any proprietary products that meet this situation. Grateful if anyone can point me in the right direction.
