PRODUCT DESCRIPTION
Product: Two-component water-based polyurethane lacquer.
Package sizes: 4.95 (4.5+0.45) litres in ultra matt.
Appearance: Creamy/milky in the container. Colourless film when dry.
TECHNICAL DATA
Coverage: 10-12 m² per litre.
Mixing: 10 parts of lacquer to 1 part of hardener.
Before application:
Shake the lacquer until all sediment is dissolved and add hardener.
Shake for a minimum of 45 seconds, let the mixture rest for 10 minutes and shake again for 45 seconds.
Pot-life: The mixture should be used within 2 hours. Avoid reuse of mixed material beyond this time.
Application tools: Brush, short haired mohair roller, air/airless spray, applicator. Apply the lacquer to the floor sparingly and evenly, rolling out the lacquer promptly so as to avoid gluing the boards together.
Substrate temperature: 15-25 °C.
Dilution: Maximum 15 % dilution with water by spray application.
Drying time at 20 °C and 50 % RH:
Approx. 3 hours.
Ready for light traffic: 8 hours.
Fully cured after 72 hours.
Apply only 2 coats of lacquer per day.
RH: Water-based products have a certain gluing effect and are therefore only recommended to be used in rooms with a stable humidity. This means that the difference between the highest and lowest relative humidity should not fluctuate more than 30 % over the year.
Cleaning of tools: Soap and water before the lacquer dries. Rollers might still contain small particles after cleaning. Therefore, the roller can only be reused for Friction Floor Lacquer.
Storage: Lasts for 1 year if unopened and stored at 20 °C. Not to be exposed to temperatures below 5 °C.
SYSTEM RECOMMENDATIONS
Untreated/sanded floors:
1 coat WB Primer 8 m²/litre or 1 coat SB Primer 10 m²/litre
+ 1-2 coats HT700 Floor Lacquer or HP800 Sport 10-12 m²/litre
+ 1 coat Friction Floor Lacquer 10-12 m²/litre.
Previously sealed floors:
Cleaning with Neutralizer
+ 1 coat Friction Floor Lacquer 10-12 m²/litre.
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 1 coat of Junckers HT700 Floor Lacquer or Junckers HP800 Sport and leave to dry overnight.
- If extra wear resistance is wanted, apply a third coat of lacquer using one of the types mentioned above.
- Alternatively, directly to 1 coat of Friction Floor Lacquer as final treatment.
- Adhesion properties are optimized if the surface is sanded with sandpaper grit 150-180 before the third coat of lacquer. If the final coat of lacquer is applied after more than 24 hours, sanding must always be carried out.
Previously sealed floors:
- Wash with Junckers Neutralizer.
- Sand thoroughly using sandpaper grit 150-180.
- Vacuum sanding dust and wipe off with a cloth well wrung in clean water.
- Apply one coat of Friction 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 before lacquering. Use sandpaper grit 24-36 to strip old coats.
- Then remove abrasion marks with sandpaper grit 60-80.
- Finally, use sandpaper grit 120-150 to obtain a completely smooth surface.
- Vacuum sanding dust carefully.
- Then seal the floor as described under “Untreated/sanded floors”.
