      Q:Fencing application

      Answer This Question

      A:  This product would work fine on a fence. It soaks in and seals the wood. It does not leave a "wood under glass" appearance like a varnish would, so it is not a clear coat in that sense. I guess that it could be considered a clear coat in the sense that it protects the wood by penetrating and sealing it without altering the appearance of the wood. We have also used this product over latex paint on exterior wood railings. There too, it penetrated and sealed without altering the appearance of the surface, and it has held up well for two years so far.

      by|Nov 20, 2020

      A:  Hi there, yes, this product can be used with a pump sprayer.

        I have three 20-year-old decks made from treated lumber on my house. Every fall I apply a clear wood protector/sealant. I think the decks have held up fairly well because of that. When my decks were new, Olympic made a product that was relatively inexpensive and held up very well, easily lasting through the year, but it had high V.O.C.s and was taken off the market. Since then I've tried different products with usually unsatisfactory results, finally settling on Thompson's WaterSeal, which is fairly cheap but seems to lose a lot of its protection ability by the time we get into summer. When I saw the positive reviews for SmartGuard and its reasonable price I decided to try some although I was a bit wary because the great majority of reviews seemed to focus on its ease of application while only a few mentioned performance, and those were not very positive, with one specifically mentioning that water did not bead up on SmartGuard. I decided to do a test by applying SmartGuard to half of one of the decks and Thompson's to the other half. The remaining two decks I used only SmartGuard. I applied the SmartGuard with a pump sprayer, but found that to get good coverage I needed to also spread it out with a pad, which is what I use to apply the Thompson's. At first, water seemed to bead up equally well on both the SmartGuard and the Thompson's, but after a week or so the SmartGuard side did not bead up. One reviewer mentioned that they thought multiple applications of SmartGuard worked best, so I applied a second coating. The results were not any better. It has now been several more weeks and the SmartGuard side does not bead up at all while the Thompson's side beads up like it did in the beginning. The other two decks where I applied only SmartGuard are also not beading up at all. It's always possible that water beading does not definitely indicate water protection, but I don't know what other criterion to use. Unless some other more promising product comes out at a reasonable price I'll probably be going back to using the Thompson's on my decks next year.

          I have a deck that's pushing 20 years old and is on its last leg. As such, I'm not trying to invest a lot of time or effort in prolonging the inevitable. However, this water sealer sounded so simple I figured it was worth a shot. It was super easy to apply, just mix and spray. It took about 10 minutes to spray my deck and it was dry in an hour. After it was dry water beaded right up. Don't know how long it will be effective, but for ease of application I'll give it up a thumbs up even if it's just a season!

          Excellent sealer
          [This review was collected as part of a promotion.] So, finally we are enjoying the nice weather again, of our backyard and sitting on the deck is part of it, of course taking constantly care of it is required, but using the right products makes everything easier, using the Olympic SmartGuard Clear Multi-Surface Sealer for the first time made a big difference, it is so easy to use and apply that anyone could take care of it, definitely we will keep using it as part of the products for the regular maintenance.

            This is the easiest way to seal wood outdoors. Basically I just mixed this pack in a garden sprayer with water and sealed my kids wooden playscape. It went on super easy and coverage was perfect. At the end, cleaning the sprayer was quick and easy, just using water. After using other methods, including brushing on, this saved time and worked just as well or better. I will be using this every few years to seal the playscape.

            This "CLEAR SMARTGUARD MULTI-SURFACE SEALER" is a pretty good product. Where I used it was on my outdoor Wood/Gas Stone Pizza Oven. I had some cracks so I wanted to protect the exterior stone form rain, snow, etc.. I did not want to cover it all the time. I hope it does the trick. Easy to use and easy to clean up if anything spills. No discoloration in the stone and penetrated well. I tested it during the last rain fall and the water was beading off with no water in the oven.

              Smart Guard is a Smart Choice
              [This review was collected as part of a promotion.] I used the Olypmic SmartGuard Clear Multi-Surface Spray Sealer to reseal my fence. It was super easy to mix, and spray. I love that it is rain-ready in one hour! I can attest to this as it rained only a few hours after I finished applying! I definitely recommend for your home projects!

                  Clear multi-surface spray sealer. Description says you can use on wood, masonry, concrete and weathered composite, but the small print says NOT to use it on a garage floor. Contacted Olympic and they said that the product should not be used where cars with "hot tires" could cross over it because the tires may leave marks on the floor. This should be part of the product description on the Home Depot site. Can be sprayed but I used a roller. Mixed the SmartGuard and water in a "Home Depot" bucket. Dunked the roller in the bucketing than spread on the sealer. I used it on a pressed concrete patio and part of my basement boat garage. After drying, it does leave the concrete a little darker.
