APPLICATION INFORMATION
Do not shake varnish. Stir gently before application, being careful not to introduce air bubbles into the varnish. Z-Spar Ultra Clear Varnish may be applied by
brush, conventional or airless spray. Thinning is not normally required although on warm days use Pettit 120 Brushing Thinner at 5-10% by volume to ease
brushing and maintain good flow and leveling. When spraying, use Pettit 121 Spraying Thinner up to 20% by volume. Spray one even, wet coat to minimize
orange peel. Do not apply in heavy films or build coats too quickly as solvent entrapment, blistering or wrinkling may occur. Do not apply Ultra Clear Varnish on
extremely humid days or when rain is threatening. Do not apply in the late afternoon when working outdoors as the wet film may be adversely affected by dew.
DO NOT apply this varnish to a wood hull which has been dried more than one week under conditions such as artificial heat. Do not use Ultra Clear Varnish
below the waterline on boats that remain in the water. The moisture content of the wood should be a minimum of 15% when varnished. This will eliminate
expansion cracking, micro-checking and gloss loss when the varnish is in service.
SURFACE PREPARATION
Wood must be clean, dry and properly prepared prior to varnishing. When sanding wood, always sand with the grain. Use a vacuum, air hose, or tack rag to
remove all traces of sanding residue. Follow all surface preparation steps carefully, avoiding shortcuts. Inadequate surface preparation will virtually assure
inadequate varnish performance.
SYSTEMS
Bare Wood
1. Sand surface completely smooth with 180-320 grit production paper. Wipe surface to remove sanding residue with a tack rag or rag dampened with Pettit
120 Brushing Thinner.
2. For new work on open grained wood such as mahogany, oak, ash, etc. the use of Pettit or Z-Spar Paste Wood Filler Stain is required to achieve a smooth
finish. Let dry overnight. For new work on close grained woods such as pine, maple, spruce, etc. the use of Pettit or Z-Spar Paste Wood Filler Stain is not
normally required.
3. Apply a generous covering coat of Pettit 2018 EZ WoodSealer Let it dry overnight and sand thoroughly with 220 grit sandpaper. On especially rough or
porous wood, a second coat of 2018 EZ WoodSealer may be applied. If applied, sand the second coat as well and wipe the surfac e clean with a tack rag or a
rag dampened with Pettit 120 Brushing Thinner.
4. Apply at least five coats of Z-Spar Ultra Clear Varnish. Let each coat dry overnight, sand with 220 grit sandpaper, and clean off sanding residue with a tack
rag before applying the next coat. Sand the next to last coat with 400 grit production paper and clean off sanding residue with a tack rag before applying the
final coat. *NOTE: If temperature is above 70°F recoating may be done between 12 and 24 hours without sanding. If the varnish has dried longer than 24
hours, sand and recoat.
Varnished Wood in Good Condition
1. Wipe old varnish with Pettit 120 Brushing Thinner to be sure all dirt, wax, polish and/or grease has been removed.
2. Thoroughly sand the existing varnish with 180-220 grit production paper and wipe clean with a tack rag.
3. Apply at least two coats of Z-Spar Ultra Clear Varnish Let the first coat dry overnight, sand with 400 grit sandpaper and clean off sanding residue with a tack
rag before applying the final coat.
Varnished Wood in Poor Condition
1. Remove all the old varnish with a paint and varnish remover or by sanding.
2. Bleach the wood if necessary to remove water stains.
3. Proceed with the system for bare wood shown above.
Bare Teak- (or other woods with high oil content)
1. Sand the wood smooth with 120 grit production paper to open up the grain. Wipe the surface thoroughly with Pettit 120 Brushing Thinner in an effort to
aggressively remove as much oil as possible.
2. Apply a generous coat of Pettit 2018 EZ WoodSealer. After an overnight dry, lightly sand the surface with 220 grit sandpaper and wipe it clean with a rag
dampened with Pettit 120 Brushing Thinner.
3. Apply at least five coats of Z-Spar Ultra-Clear Varnish. Let each coat dry overnight, sand with 220 grit sandpaper, and clean off sanding residue with a tack
rag before applying the next coat. Sand the next to last coat with 400 grit production paper prior to applying the final coat.
It should be noted that woods with a high oil content may eventually experience adhesion problems as there is no way to totally eliminate the oil and prevent it
