Overview:
Old Masters Exterior Oil-Based Spar-Marine Varnish is a durable exterior coating
for use on wood surfaces. It contains ultraviolet absorbers for advanced sun
protection. Use on exterior surfaces such as fences, railings, lawn furniture, doors,
boats and marine surfaces. For interior use on windowsills and door frames for
added ultraviolet protection. DO NOT USE on wooden decks or steps, wood siding, log homes or wood boats below water-line.
As with all exterior clear finishes, this product will not offer unlimited protection
against the elements. Surfaces which receive direct sunlight may have to be recoated annually to maintain gloss and to prevent cracking and peeling.

All surfaces must be clean, dry and free from dirt, wax, grease, glue and other
contaminants or penetration and adhesion will be affected.
-
Bare Wood Surfaces: Sand surface thoroughly with medium grit sandpaper and
progress to fine grit sandpaper. Always sand in the direction of the wood grain.
Remove dust with a tack rag. -
Previously Finished Wood: Surface should be sanded to remove imperfections and gloss, using extra fine sandpaper (220 grit), sanding with the grain. Remove dust with a tack rag.

conditions, allow 8 to 16 hours before recoating. Overnight drying is

finish and promote adhesion. If sandpaper gums up allow more dry time. Remove
sanding dust.
