Previously sealed floors:
Clean with Junckers SylvaNeutralizer. Sand thoroughly using grit 150-180. Vacuum sanding dust and wipe off with a cloth well wrung in 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 functioning and the appearance of the surface is acceptable, the floor can be sealed with one coat of Junckers Strong Premium.
If the trial application is 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”.
