Man O' War Spar Varnish

A marine-grade varnish formulated to stand up to weather and waves.
Item #

Rating:
92% of 100

This is a fantastic alkyd-based marine-grade varnish, suitable for both outdoor and indoor use. Provides excellent protection from weathering and the elements, including UV rays and salt water. Ideal for boats, outdoor furniture, exterior doors, sills and more. Superior to polyurethane because it is flexible enough to expand with the wood, resists cracking and peeling, and adheres well to oily woods like teak and mahogany. Flows on freely for easy brushing. Not suitable for continuous submersion.

Top coats for epoxy base
I used this finish as the top coats for a classic boat wood swim platform. The base coat and sealant is a West System epoxy.

This was applied after the epoxy cured and was prepped by light sanding and an acetone wipe down. Really happy with how only a single coat held up for two months of direct sunlight exposure and regular use before additional coats were put on.

Although varnish over epoxy isn’t explicitly mentioned in the product directions, it seems to be working very well with the west systems 105 resin and 215 special clear hardener (which also has UV additives).

The product flows really well and builds nicely on horizontal surface. Vertical surfaces would need to be watched for runs.

The satin finish looks great and is not slippery when wet, which is desirable for this application.
Second coat over epoxy after first exposed to elements for about 3 months.

Easy to apply
The product was used on a original front door on a house built in the 1930’s, facing west. Application was easy and we will see how the four coats holds up.

Lifetime of various woodworking projects: lamps, gunstocks, art from found materials, trim work and refinishing/restoring
I love it. And i really love that i could find non-urethane spar varnish. Goes on beautifully with white china bristle angle trim brush. Can be cut by one third with mineral spirits (directions say 5%) for penetration AND for multiple succeeding coats.

I knew Rockler from years ago. Thank you a bunch

Have a nice outdoor project? You need this.
My wife insisted we go with a marine spar varnish for our front door. We have four coats on in- each taking it a bit "darker"- not exactly the right word. The finish is amazing, and I am confident will last a very long time, even in Colorado extremes of heat, cold, snow and sun.

Great varnish, worth every penny.
I love this varnish. Using it on an outside pine patio cover. Rough lumber soaks it up, but on the 3rd coat it is solid. I won't have to re-varnish for 8 years.
Even though EPA has banned it in several states, you can still find it at Rockler.
Use a vapor mask while applying & you'll be fine.

This is absolutely the best marine varnish I have ever used. I have my painter use it on the wood exterior doors on upper end houses. It seems to last and flex better than others.

Ken W on May 3, 2017
Can you use this on any substance other than wood? The paint store gave it to me to protect an outdoor repainted resin statue.
P A on Mar 31, 2016
BEST ANSWER: While it will protect against the elements be sure the statue is free from any loose paint before applying. If the paint currently on the statue doesn't stick to the statue then the varnish won't either. I would be certain there is no mildew and the surface is completely dry before applying. Remember to apply using several thin coats as opposed to a thick coat. Sand between coats. Hope this helps
