Untreated floors:
Ensure that the surface is absolutely clean, dry and free from dust, wax, grease, polish, soap residues etc. Sand the surface to remove dirt and irregularities. Vacuum thoroughly and and make sure to take precautionary measures against new concrete where concrete slurry may have been left on the floor.

  • Apply one coat of lacquer and leave to dry according to recommendation.
  • Sand with sandpaper grit 150-180 and vacuum sanding dust.
  • Apply a second coat of lacquer and leave to dry overnight.
  • A third coat can be applied for added durability.
  • Adhesion properties are optimized if the surface is sanded with sandpaper grit 150-180 before the third coat of lacquer. If the third coat of lacquer is applied after more than 24 hours, sanding must always be carried out.

Previously sealed floors:

  • To dissolve old soap residues, first wash the floor with Junckers Neutralizer.
  • Sand thoroughly using grit 150-180 and vacuum sanding dust.
  • Apply one coat of lacquer and leave to dry.
  • Before lacquering the full area, it is recommended to conduct a trial application on a smaller area.

How to conduct a trial application:
Lacquer a couple of spots, 2 coats at 4 hours interval. After drying for 24 hours check the spots for adhesion by scraping with the edge of a coin. If the adhesion is functioning and the appearance of the surface is acceptable, the floor can be lacquered. If the result is not acceptable, sand the floor down to the bare concrete. Then apply the lacquer as described under "Untreated floors".


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