Floors not previously sealed with PUR Professional:

  • Floors treated with wax or polish must be thoroughly cleaned with Junckers PUR Intensive Cleaner before the floor is sealed.
  • Use a mop to spread the cleaning agent and work it using a buffing machine mounted with a black nylon scouring pad.
  • Then wash the floor with clean water and make sure that no residues are left on the surface.
  • Leave to dry for 4-8 hours.

Especially for linoleum floors:
If the surface after cleaning feels rough and uneven, it may be necessary to lightly sand the surface with 150–180 grit sandpaper.

  • Apply one coat of Junckers PUR Professional.
  • Leave to dry for a minimum of 3 hours and then apply the final coat.
  • Leave to dry completely before use.
  • Before sealing the full area, it is recommended to conduct a trial application on a smaller area.

Discoloured aged linoleums floors:
The above mentioned method is a way of maintaining the surface and establishes only to some extent the original colour. More in-depth mechanical abrasion must be conducted, if the original colour is to be restored.

Previously sealed floors:

  • Mix Junckers SylvaNeutralizer in warm water and clean the floor. 
  • When the floor is dry, sand lightly using grit 150-180 sandpaper.
  • Vacuum sanding dust and wipe off with a cloth well wrung in clean water.
  • Apply one coat of PUR Professional and leave to dry.
  • Before sealing the full area, it is recommended to conduct a trial application on a smaller area. 


Before using the product, read the label on the container carefully and observe the recommended precautionary measures. See Safety Data Sheet for detailed information.
