DIRECTION FOR USE

Untreated/Sanded 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 wipe off with a well wrung cloth and clean water.

Apply one coat of Junckers PreLak or Junckers BasePrime. Leave to dry.

Sand with 150-180 grit sandpaper along the fibres of the wood. Vacuum sanding dust and wipe off with a well wrung cloth and clean water.

Apply a coat of Junckers HP Commercial. Leave to dry overnight and then apply the final coat.

Previously sealed floors:
Wash with Junckers Sylva Neutralizer. Sand thoroughly using grit 150-180. Vacuum sanding dust and wipe off with a well wrung cloth and clean water.

Trial applications should be conducted on 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 good and the surface is acceptable, the floor can be lacquered with one coat of Junckers HP Commercial. If not satisfactory, proceed as described under “Wax/Polish Treated floors”.

Wax/polish treated floors:
​Machine sand before lacquering. Use grain size 24-36 to strip old coats. Then remove abrasion marks with grain size 60-80. Finally, use grain size 120-150 to obtain a completely smooth surface. Vacuum sanding dust carefully. Then seal the floor as described under “Untreated/Sanded floors”.
