Customer Questions & Answers

Will this work on a seasonal dance floor in Alaska with no heat in the winter?

Asked by: Glen
Happy to help, Glen. Varathane Oil-Based Spar Urethane is not recommended for high traffic areas. The product will crack and peel. Instead, try Varathane Water-Base Floor Finish.

Rated 5 out of 5 by from VERY Good Product Used this product on wood fence last fall. Protects the wood, nice shine and dries quick. Want to put another coat on the 3 fence sections this spring. And have new landscape timbers that have weathered over winter that are getting a coat of this Urethane late spring or early summer. Nice shine to the product. Bought 6 gallons this year. Will buy more when they are done!!

Rated 5 out of 5 by from Quality product Why I chose an oil based Urethane over the easier to use water base. I was looking for the amber tone that oil base Urethane's have. When you are re-coating a surface that has had an oil base varnish etc applied to it and some of the old coating has weathered down to the bare wood only an oil base coating will have the amber color in it to match as close as possible to the existing color. A water based coating will not have the amber color and you will get a finish coat that will be very blotchy in color. The only way to use a water based clear is to first apply a stain to match the existing color.

Rated 3 out of 5 by from Not like old Spar Varnish After applying to my replacement knotty pine siding on my house I read the label, okay, my fault, guys don't follow instructions well. The label says not intended for siding or something like that. Ooops. Additionally, after reading up on mildew information on the web, it says some varnish formulations today actually encourage mildew growth. Nice. Fortunately from my years of former professional painting I did mix in an after market mildewcide prior to application. We'll see how that works. Probably negated any implied suitability for purpose but I know that doing nothing didn't work either. So from the homeowners perspective, the EPA has taken materials out of products that actually perform, so now the result is siding that should have lasted 30 years or more looks bad in 5 years. Thus necessitating the replacement. I'd say this is a little counterproductive from an environmental standpoint. The sad thing is, there aren't many options today and no common sense. Unfortunately, it doesn't stop there either. Many products that used to work with older formulations, like resilient flooring adhesives, now often fail immediately or soon after installation so that certainly helped the environment didn't it? (Ask any flooring contractor) So the review/rating I have shared reflects more on what industry has been forced to do, rather than the product itself in its present formulation. It applied fine and leveled out well. Those are things that are somewhat important but longevity is what really matters and that I won't know for years. Given no other real options, I would say it is the best out there for the price. How's that for a treatise..........

Rated 4 out of 5 by from Rust oleum product Ok product goes on heavy straight outta the can. If it's not brushed out will Kringle dry. Sq footage not as labeled. Picked up another gallon from amazing at a lower $ and will thin that for a better flow and area. Would buy again? After the test of time
