DIRECTIONS FOR USE
Untreated/sanded floors:
The surface should be clean, dry and free from dust, wax, grease, polish etc. Machine sand the surface to remove dirt and irregularities. Vacuum thoroughly and wipe off with a cloth well wrung in clean water.
The final sanding, before applying WB Primer clear, should be carried out by using sandpaper grit 120-150.
The final sanding, before applying coloured WB Primer, should be carried out by using sandpaper grit 150-180. This gives the lacquered surface a more uniform appearance.
- Apply 1 coat of WB Primer in an even layer.
- When using coloured WB Primer an additional coat can be applied to obtain more colour intensity.
- Make sure that overlapping edges on the lacquered area do not dry out during treatment.
- Do not apply more than 2 coats per day.
- When the primer is dry, sand with sandpaper grit 150-180 or a black screening pad.
- Finish with 2 coats of one of Junckers' water-based floor lacquers.
Previously sealed floors:
- Machine sand before applying WB Primer.
- Use sandpaper grit 24-36 to strip privious coats.
- Then remove abrasion marks with sandpaper grit 60-80.
- Prime the floor as described under “Untreated/sanded floors”.
