System Recommendations

Untreated/Sanded Floors:
1 coat Junckers PreLak 8 m²/litre or 1 coat Junckers Baseprime 10 m²/litre
+ 2 coats Junckers HP Sport 10-12 m²/litre.

Previously sealed floors:
1 coat Junckers HP Sport 10-12 m²/litre.


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 Sport. Leave to dry overnight and then apply the final coat.
Apply any line markings before this 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 Sport. If not satisfactory, proceed as 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”.


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