  • APPLICATION INFORMATION
    Do not shake varnish. Stir gently before application, being careful not to introduce air bubbles into the varnish. Z*Spar 1015 Captain's Varnish may be applied by brush, conventional or airless spray. Thinning is not normally required although on warm days use Pettit 120/T10 Brushing Thinner at 5- 10% by volume to ease brushing and maintain good flow and levelling. When spraying, use Pettit 121/T8 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 Captain's 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 Captain's 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.

Good results, even for a rank amateur!
By Woody from Athens, Ga

Verified Purchase

After numerous YouTubes and reading instructions on everything from brushes, dust abatement and "tipping off", I took the plunge with the Captain's varnish. After spending hours building a specialty Yacht step box, I didn't want to ruin the end result with a finish that was something less than fantastic. The varnish was great, my skills improved and the result is something I can be proud of. The next time will be even better now that I've learned lessons that only experience can teach. One of those lessons is to keep using Captain's Varnish!

By dlidster from Iowa

I'm not certain Captain's Varnish is the best on the market, but I know how it behaves and I'm very comfortable using it. I've been using it exclusively for more than 25 years. It's very predictable if I stick to my routines.

Bottom Line Yes, I would recommend to a friend

Z Spar has been a good product.
By John Dickinson from Spring Hill, Tn

Verified Purchase

Z spar has been a good choice for my needs. I am using it for my front door where the door gets a lot of sun and rain in Spring Hill Tn. I have to repaint the door every 2 or 3 years after applying 3 coats. It would be nice if there was a product that last longer.

Bottom Line Yes, I would recommend to a friend

The perfect spar varnish
By Carl from Kennebunkport, ME

Verified Purchase

I use this product on brightwork and spars. Also on stained, pine Adirondack chairs with 5-6 coats. Absolutely gorgeous deepening the color of the stain with an amber glow.
