        Happy to help, Forrest! Yes, Rust-Oleum Varathane Oil-Based Spar Urethane can be used provided the areas that are coated will not be immersed in water. The constant exposure to water can cause the finish to blister and peel. - Rust-Oleum Product Support 3

            Deck, structurally sound, entirely covered by house roof. Years ago, Olympic rep sold me a lightly tinted Olympic clear oil stain, advising re-coat every few years. Just re-coated. After 2 weeks, looks good but still washes off with detergent. Varnish?

            Thanks for reaching out. Varathane Oil Based Spar Urethane cannot be applied to a deck, it is not formulated to withstand foot traffic. Give us a call at 800-373-6333 so we can hear more about your deck and provide the correct product recommendation. - Rust-Oleum Product Support 6

              Can I use this to re-coat my interior original hardwood floor.
              ByDec 29, 2021
              1 Answer | 
              Answer This Question

              Thanks for reaching out! We're so glad to hear of the success you had with the Rust-Oleum Varathane Spar Urethane. Spar's are used for exterior applications due to the flexing of the wood. The wood needs to expand and contract with temperature changes and for this reason, this product is going to remain a little softer to allow for that movement. We would advise against use of this product for an interior wood floor because it would not hold up properly and would also not handle foot traffic. Instead, consider the Varathane Oil-Based Floor Finish for your interior flooring needs. https://www.homedepot.com/p/Varathane-1-gal-Clear-Gloss-350-VOC-Oil-Based-Floor-Finish-Polyurethane-214550/305576983 - Rust-Oleum Product Support 1

                Answer This Question

                Great question! Rust-Oleum Varathane Oil-based Spar Urethane should not be thinned as it will adversely affect the product performance and drying. - Rust-Oleum Product Support 5

                      Real good company
                      [This review was collected as part of a promotion.] I haven't used the Varathane clear gloss oil based urethane yet because it's too cold outside. It says to apply between 50 and 90 degrees. It has not gotten higher than 50 degrees where I live. As soon as it gets warm enough I will be using it. I actually can't waiting to use it because this is a good company and their products get the job done.

                        Made my rocker look new again!
                        [This review was collected as part of a promotion.] This was so easy to use. It took very little of the gloss to cover the rocking chair. The odor was really strong and was strong for a few hours. The drying time was between 2 and 24 hours. The first couple hours it was sticky to the touch but was drying pretty fast. It was completely dry by the next evening. This seems to be very durable and will hold up.

                          Keeps the mildew out of outdoor projects!
                          [This review was collected as part of a promotion.] The odor for this urethane is not bad compared to other brands! i used this for my outdoor porch! it helps keep the mildew out when it rains! i put it on-top of my painted porch and it seals everything together. It dries pretty quickly if you do the job in a sunny day.

                            Great shine, quick drying!
                            [This review was collected as part of a promotion.] This spar urethane is the perfect finishing touch! It provides great coverage with very smooth application. It only took around 20 minutes to dry in the sunlight and provides a great shine. This is my go-to finisher for all my wood projects.

                              Strong and beautiful finish
                              [This review was collected as part of a promotion.] This spar urethane is great for interior or exterior. It makes the project water and UV resistant. It brushes on very smooth and covers a lot of area. It does take some time to dry between coats but has a low oder. I used this can on taking some rough sawn red oak and turning it into a floating shelf and a bench for a laundry room make over. The finish is very durable, resistant to chemicals, and nearly scratch proof. My go to choice for long life top coats.

                                Really made cedar furniture shine
                                [This review was collected as part of a promotion.] I received this for free from Influenster for my honest review. The shipping of these items were in a thin box and both quart cans were dented, but it did not affect the product. Not sure if this is normal shipping method. The product has a strong scent because well it is a “paint” product, wear a paint respirator if you use this indoors. This is exterior urethane which I needed for a project. This spread well and dried within the day where even cooler temperature the furniture was slightly tacky, prefer to use in weather over 80, it was in low 70s. The urethane really brought out the red in the cedar custom patio furniture. Looks great! It also brought my old bench back to life, it was sun beaten and I sanded it down and applied urethane. I hope the waterproofing helps to keep my patio furniture looking great, only time will tell, but right now furniture looks awesome!

                                  [This review was collected as part of a promotion.] Works great, looks great. Very happy with this product. The can was a little flimsy but it wasn’t a dealbreaker. It was very easy to apply and dried super quick. The odor was very minimal but I did apply it outside.
