Untreated/sanded floors:
Ensure that the surface is absolutely clean, dry and free from dust, wax, grease, polish etc. Sand the surface to remove dirt and irregularities. Vacuum thoroughly and wipe off with a cloth well wrung in clean water.

  • Prime with one coat of MT400 Floor Lacquer and allow drying for 24 hours.
  • Sand with sandpaper grit 150-180 along the fibres of the wood.
  • Vacuum sanding dust and wipe off with a cloth well wrung in clean water.
  • Apply 2 finishing coats of MT400 Floor Lacquer.

Previously sealed floors:

  • Wash with Junckers Neutralizer.
  • Sand thoroughly using grit 150-180.
  • Vacuum sanding dust and wipe off with a cloth well wrung in clean water.
  • Apply one coat of MT400 Floor 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, continue as described under “Wax/polish treated floors”.

Wax/polish treated floors:

  • Machine sand using grit 24-36 to strip old coats.
  • Then remove abrasion marks with grit 60-80. Finally, use grit 120-150 to obtain a completely smooth surface.
  • Vacuum sanding dust and wipe off with a cloth well wrung in clean water.
  • Then seal the floor as described under “Untreated/sanded 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.
