A:  Thanks for reaching out Robin. Varathane Oil Based Spar Urethane is for use outdoors only, it cannot be used indoors, it will not dry properly. The correct product to use on indoor wood is Varathane Oil Based Ultimate Polyurethane. The Spar Urethane will need to be completely removed before applying the Polyurethane. Give us a call at 800-901-0411 so we can hear more about your application and try to make things right. https://www.homedepot.com/p/Varathane-1-qt-Clear-Semi-Gloss-Oil-Based-Interior-Polyurethane-341721/305583792 - Rust-Oleum Product Support 6

          Q:Can this be applied over wood with polyurethane finish
          by|Sep 23, 2021
          1 Answer
          Answer This Question

          A:  Thank you for reaching out! While our Varathane Spar Urethane will adhere to polyurethane that has been scuff-sanded with 220 grit sandpaper, it will not block UV from yellowing the polyurethane over time. If applying to an exterior wood surface, we would recommend removing the polyurethane prior to applying the spar urethane to ensure proper performance. - Rust-Oleum Product Support 2

            Great product for waterproofing and sealing wood exposed to the So Cal elements. We don’t have snow in San Diego. It holds up well for our local climate. I use it to protected stained structures and gates.

            Over promised under deliver - do not take a chance with this product
            Bought this product for my outdoor wooden bench as the in-store specialist highly recommended. Also suggested because it should last for years. The treated wood on which this solution was not applied is looking horrible in merely months. See attached picture for cracks and poor color output. Would not recommended to use this product as a sealer especially when the surface is exterior and expose to sun and rain.

            That was not the intention! Please keep in mind that a minimum of 3 light coats of Rust-Oleum Varathane Oil-based Spar Urethane must be applied to build up the right surface protection. - Rust-Oleum Product Support 5 Rustoleum

              Spar urethane is good for outdoor applications. It has superior water and UV protection compared to other products. I used this on an indoor application for a butcher block top for a laundry room sink, where it may be in constant contact with damp or wet clothes. The product goes on thick and streaky, however it gives poor coverage. I had to put on 4-5 coats for a good finish. I tried a disposable sponge brush applicator, but this did not work well, I had better results with a natural bristle brush applying in only one direction, and working quickly. Mineral spirits are needed for clean up of the brush. I had to wet sand from 400-2,000 grit in order to get out a few drips and brush marks. The finish looked a little matte until I completed the wet sanding. If you don't need full UV, mold & mildew resistance for an outdoor application, then I would stick to a regular polyurethane, as it gives better aesthetic results and is much easier to get a good finish. I give this a 3.5 star rating out of 5.

              Thank you for your feedback, Tom! Yes, Rust-Oleum Varathane Oil-Based Spar Urethane is intended for use on exterior surfaces only. We do not recommend it for use on interior surfaces. We do recommend applying this product with a a good quality natural bristle brush or applicator. For interior use, we recommend a Rust-Oleum Varathane Ultimate Polyurethane instead!

              It goes on with few drips. The finish is very tough and is standing up to direct afternoon sun! Four coats were applied, waiting 24 hrs. between coats then lightly sand each time. The finish, along with the gel stain, has increased the beauty of my front door!
