DIRECTION FOR USE
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.
Prime with one coat of PreLak or BasePrime. 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 one coat of Strong Premium. Leave to dry overnight and then apply the finishing coat.
Previously sealed floors:
Clean with 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 Strong Premium. If the result is not acceptable, continue 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”.
Before using the product, read the label on the container carefully and observe the recommended precautionary measures.
