GENERAL DESCRIPTION
Low-odour, two-component hard-wearing water-based polyurethane lacquer. Recommended for wooden floors in high wear areas such as retail, restaurants, museums and educational institutions.
Suitable for previously sealed as well as for new or fully sanded old floors.
When lacquering an untreated floor or a floor sanded to bare wood, use one of Junckers' primers prior to the finishing top seal. HT700 Floor Lacquer must be mixed with hardener before use.
HT700 Floor Lacquer has received the Danish Indoor Climate Labelling. A product with this labelling has undergone extensive volatile emission and odour tests. This ensures that there are no chemical substances in the product which adversely affect the air quality in the room.
For professional use.

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.

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 a coat of HT700 Floor Lacquer.
- Leave to dry overnight and then apply the final coat.
- Adhesion properties are optimized if the surface is sanded with sandpaper grit 150-180 before 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 floors:
- Wash with Junckers Neutralizer and 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 HT700 Floor Lacquer and leave to dry.
- Before lacquering the full area, it is recommended to conduct a trial application on a smaller area.
Tip for UV-lacquered floors: Pay particular attention to UV-lacquered engineered floors. For uptimal adhesion we recommended to replace ordinary sandpaper with a 180-240 grit diamond sanding pad.
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 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”.
