Q:Will it withstand a chair with casters on tempered wood?
by|Nov 22, 2023
1 Answer
Answer This Question

A:  Hi Greg, thanks for your question. Although our Spar Urethane Wood Sealer provides superior durability and abrasion resistance, it's not designed for use on floors, including tempered wood flooring. It is ideal for patio furniture, doors, and wooden handrails. Have a great day! - Randy

    Q:I used varathane classic penetrating wood stain on pine shelves we made. Can I use beer water based polyurethane satin over this?
    by|Nov 5, 2023
    1 Answer
    Answer This Question

    A:  Hi Tonya, thank you for your question. As it turns out, our Water-Based Polyurethane and Spar Urethane are not recommended to be applied over oil-based stains. Instead, it's best to use our Oil-Base Polyurethane. Have a great day! - Randy

      Q:What is drying time
      by|Nov 3, 2023
      1 Answer
      Answer This Question

      A:  Hi Francis, thanks for the question. For the drying time, you want to wait at least one hour between coats, 12-24 hours before light use, and it takes 3 days for the urethane to completely cure. Have a great day! -Ronald

        A:  Hi Johns, thanks for the question. I wouldn't recommend using our Spar Urethane over a fiberglass door. I'd recommend checking with your local home improvement store for an appropriate product. Have a great day! -Ronald

          Quick shipping and delivery. I use this water-based exterior urethane to seal my live-edge birdhouses. Goes on easy and dries quick. Two coats is needed to preserve grain and wood tone.

          Easy to use and clean up
          I applied this Spar Urethane with a synthetic brush and found it pretty easy to use. I really like that it is water based so that I didn’t need any special solvents to clean up with . The finish is satin so it has a sheen to it without making my modern outdoor wood furniture too glossy . Ill be using three coats on the wood but even after one or two you can tell that it is protecting the furniture from sun and wear.

            Oil vs water based
            Not sure what's going on. I refinished a wooden ladder. The top stair I did with water based on the underside and top side with oil based- both are Behr satin. Key thing - both were striped down and sanded and is the same wood. The one with oil based has a richer color and more visible grain. Water based is convenient to use but I'm sticking with oil.

            Excellent SPAR polyurethane finish
            I went into Home Depot to buy either a Varathane or a MinWax SPAR polyurethane, but the BEHR SPAR urethane was the only choice so I bought it. I'm glad I did; I applied it to a teak bistro table with weather damage to its previous layers of Danish oil. By the third coat the BEHR SPAR urethane sealed the inconsistencies in teakwood from sanding into the old finish, and leveled out beautifully. I applied a 4th coat just to give it extra weather protection.

              First i would like to complement Behr on their shipping methods. This can shows up set into a plastic plate top and bottom and into a tight fitting box. This protects it from denting and other damage and the cans arrived in perfect shape. That said, I have a small woodshop in my basement and any time i have tried to use an oil based finish the fumes will inevitably find their way into the rest of the house - not with this water based finish. There is still a smell, but it is minimal and easily contained to my shop space. I have used the oil based version of the spar urethane for finishing wood that will stay in my basement shop and this seems to deliver the same quality of finish without any of the drawbacks.

              I was unsure about this at first because it looked very yellow in the can and I was worried that it would bring a yellow tint to my project. However, it went on and dried very clear and does not have any yellow tinge. I suppose, on my pure white table, we will see over time whether it says pure white or turns yellow-sh... I find that most topcoats do end up making pure white things look ivory after about a year. I am already accustomed to working quickly with this type of product, so I like the fact that it dries fast. If you're new to using urethane, note that you should not do "repeating" brushstrokes... you're better off doing several very light coats. I did find that any brushstrokes (from putting on one thin coat and not going over it) did settle very nicely and dry to a smooth finish. It is a "true satin" finish... not shiny and not completely matte. Fantastic that you can clean up with water!

              This is definitely going to be my go to Wood finish for several reasons. One is the low odor. I was able to use it inside without any annoying fumes. Another is the cleanup. Just plain soap and water is all it took. No need to use solvent. Another plus is it dries to recoat in just one hour. The directions indicate three coats are required but you can use up to four if you wish. Because this is a spar urethane, I wanted to give it the outdoor test. I coated a piece of wood with three coats, allowing one hour to dry between each coat. I also lightly sanded with 220 grit sandpaper, being sure to wipe it down to remove any dust before applying the next coat. I then placed it outside for a couple of days knowing it was going to snow. I have to admit that it held up beautifully. When using this product, as with most clear finishes, you will see a slight change in the color of the wood. It makes it just a tad bit darker but not so much as to completely change the look of the wood.. My next project is to make a shower mat out of leftover bamboo flooring I used in my master bathroom. After seeing how well it held up out in the snow, I’m sure using this as a protective coating on the bamboo will allow it to withstand daily use in the shower.

              I would use an oil based product for the best results...................................................... This is an unbiased review that is unaffected by the fact that I received this product for free. As proof of impartiality, just click on my nickname and see the average of the ratings I have given over 300 reviews to date.-------- I recommend using the oil based products to obtain the best results. I sampled 3 similar Behr urethane products: 1) a gloss oil-based, 2) a semi-gloss water-based, and 3)a satin water-based.(see the photo of all 3)....... The oil-based product has a slight brown tint as we usually see with that type of "varnish". It went on virtually bubble free as opposed to the water-based products. It did result in a darker color than the "crystal clear" water-based ones. If you must have very clear appearance, use the water-based product. The water based products will appear like milk until dry, so you can see any spots that were missed although I am pretty sure that was not the intended purpose. The oil-based product will dry slower..... Clean up is as expected, water for the water based products and mineral spirits or paint thinner for the oil-based ones... Note that this urethane product is higher quality than polyurethane ones.

              Love this clear satin interior/exterior Urethane for wood out doors. Seals the wood grain completely so that water does not get in to ruin the surfaces. It is durable, easy water clan up, with great coverage. It fries quickly so that you can reapply if need be. This is a great product for all your outside wood working needs to be beautiful all year even after a hard winter.
