SYSTEM RECOMMENDATIONS
Untreated/sanded floors:
1 coat WB Primer 8 m²/litre or 1 coat SB Primer 10 m²/litre
+ 2 coats HP800 Sport 10-12 m²/litre / 110-130 sq.ft per litre (400-490 sq.ft per gallon).
Any court line paint (HP Sport Linemarking) is applied before the final coat of HP800 Sport.

1 coat HP800 Sport 10-12 m²/litre / 110-130 sq.ft per litre (400-490 sq.ft per gallon).
DIRECTIONS 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 cloth well wrung in clean water.
- Apply one coat of Junckers WB Primer or Junckers SB Primer. Leave to dry.
- 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 one coat of HP800 Sport and leave to dry overnight.
- Then apply the final coat. Any court line paint is applied before the final coat of HP800 Sport.
-
Adhesion properties are optimized if the surface is sanded with sandpaper grit 150-180 before court line paint and the final coat of lacquer. If the final coat of lacquer is applied after more than 24 hours, sanding must always be carried out.
Previously sealed/new prefinished 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 HP800 Sport 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 before lacquering. Use 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 carefully.
- Then seal the floor as described under “Untreated/sanded floors”.
