Make sure your tiles & grout are clean.
If there are stains, mould or mineral build-up, we strongly advise restoring the surface so it looks as good as new.
Use our Glass Restoration Stain Remover to restore the tiles or our Miracle Mould Removal Gel to remove stains and mould from grout.
Once the glass is restored as best as possible, rinse and dry the surface to remove any residue that might interfere with the Nanocoat.
