Do not shake varnish, stir gently before application, being careful not
to introduce air bubbles into the varnish. To prevent premature failure,
ensure correct amount of coating is applied using the coverage and mil
thickness as stated. To insure proper performance
and coverage of Sea Hawk's Captain Jack's Marine Spar Varnish, take care to apply coating evenly at proper mil thickness,
even if it means applying an extra coat. Do NOT SPRAY without proper
PPE. Avoid applying coating in direct sunlight or too much wind. A rapid
loss of solvents will occur under these conditions and decrease the
flowability. If container not close tight, skin will form. Strain it
through a paint strainer to ensure there no contamination or skin left
in the varnish.
Wood must be clean, dry and properly prepared prior to varnishing. When
sanding wood, always sand with the grain, use 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.
Sand surface completely smooth with 150-220 grit and wipe surface to
remove residue with a tack rag or mineral spirit (oily wood: removing
oil on surface will allow the varnish to penetrate for better adhesion).
If using solvent, allow adequate drying time for solvent to completely
dry out of the wood; dry time will depend on temperature. Apply at least
4 coats minimum of Captain Jack’s VARNISH. Let each coat dry overnight,
sand with 180-220 grit sandpaper before each coat, sand with 320 grit
sandpaper before the last coat. Clean off sanding residue with a tack
rag before applying each coat. For faster build-up, sand the wood 80
grit paper, apply 3 coats of Sea Hawk Paints Hawk Epoxy R1:C5 Catalyst in one day (hot coated)
and allow epoxy surface to cure over night, sand (180-220 grit) and
clean. Apply 2 coats minimum of varnish and this process will provide
you with a mirror-like finish in a shorter period of time.
Previously varnished wood IN GOOD CONDITION:
Wipe old varnish with mineral spirit to be sure all dirt, wax, polish
and grease has been removed. Sand surface with 180-220 grit paper and
remove all dust with a tack rag. Apply 2 coats minimum of new varnish.
Previously varnished wood IN POOR CONDITION:
If varnish is badly checked or peeling, remove finish to bare wood by
sanding with 80 grit sandpaper. Proceed with the system for bare wood
