Direction For Use

Untreated/Sanded Floors:
Ensure that the surface is absolutely clean, dry and free from all dust, wax, grease, polish and soapresidues etc. Sand the surface to remove dirt and irregularities. Vacuum thoroughly and wipe off with a well wrung cloth and clean water.

Apply Junckers PreLak and 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 ProFinish. Leave to dry overnight and then apply the last coat of lacquer.

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 ProFinish. If not satisfactory, proceed as described under “Wax/Polish Treated floors”.

Wax/Polish Treated Floors:
Machine sand by first using grit 24-36 to strip old coats. Then remove abrasion marks using grit 60-80.

​Finally, use grit 120-150 to obtain a completely smooth surface. Vacuum thoroughly. Treat the floor as described under “Untreated/ Sanded floors”.
