Buyer beware. Does not protect from water
I purchased this to seal my newly installed wood fence. A month later after a little rain the fence was all warped from the water. I followed the directions and even laid it on really heavy and double coated it. I should have realized something was wrong when I noticed how thin and milky it was. I did a small portion with another brand and it did not warp. This stuff does not work and now I ruined my $7k new fence. I'm very unsatisfied does not begin to describe my feelings for this product. They should pull this junks of the market.

    Don’t buy
    Don’t waste your money. I ran out of the other brand and bought Olympic Waterguard. I had a little left of the other Brand and then started using Olympic for some pergola parts. I left it to dry for about an hour then it started raining and when I came out, Olympic didn’t repel squat!

      Caused mildew on rafters
      We applied the Waterguard clear wood sealer to our new gazebo. Now after 5 months and past the heavy rains we have mildew on the rafters. We read that this product would prevent this. We follow the directions as stated on the container.

        Easy to use!
        [This review was collected as part of a promotion.] We built an enclosed raised bed garden structure this year. A lot of hard work and am so happy to have tried this product! It looks milky (not clear) when it comes out of the can but it does dry clear. It is easy to apply, we mostly used brushes due to the size wood we had. But I'm going to use it on our deck too hopefully and I think we will try to roll it on the floor. We've had extreme weather this year - torrential rains for a month, then drought and high heat, so we've only had this on for about 2 weeks. So far, it looks great! The Garden sits out in the open ...so it will get a lot of weather! Rains, snow and sun!

          Overall good sealant
          [This review was collected as part of a promotion.] I treated my three year old deck made of pressure treated wood. It goes on milky, but does dry to clear. It dried very rapidly as well. I tested the seal with some water the next day and was happy with the difference between treated and untreated. Cleanup was also very easy. Overall a good product.

            No good for red wood
            I applied 3 coats to a beautiful hand made red wood swing built by my father. After 1 month outside it did not protect the color of the wood whatsoever ever I have attached before and after photos Very heart breaking and do not recommend this product at all !!!

              Enhances wood beauty and adds protection!
              [This review was collected as part of a promotion.] Olympic WaterGuard® for Wood Waterproofing Sealant Clear is a good wood protector and sealer that can be applied with a brush, roller, or sprayed on. I choose long handle and rolled mine on our fence. The sealer is a milky white color when applied but dried clears up after it dries.. After a few hours I checked the fence and the milky white had cleared and there was a nice waterproof sheen to the wood. It protects from water and sun damage. Yes, I would not hesitate to use again to protect my fence from harsh elements.

                Water beads right off
                [This review was collected as part of a promotion.] I like the waterproof sealer because it doesn’t actually change the color of the wood it just sheds off the water. I also find this works better than paint or stain on my deck. The stain and paint always seem to peel off. It is also very easy to apply. I used this clear wood sealer on my wooden deck and it looks amazing. I would definitely recommend it.

                  Revived my fence
                  [This review was collected as part of a promotion.] Applied Olympic WaterGuard for wood Waterproofing Sealant Clear to my 10 year old fence after I pressure washed it. It really brings out the beauty of the wood. I included a before and after picture of the results. I expect to repeat the process every two years. But it isn’t all that bad. Used a brush to apply.
