Deck Surface has grey Splotches
Our treated wood deck is less than a year old. Since it’s just my wife and I, the deck gets little use. To protect the deck, I purchased Olympic Maximum based on Consumers Report review. I power washed and cleans the deck thoroughly before applying one coat. Weather was clear for days after. After a few weeks we started noticing grey splotches all over the deck (see pictures). They can’t be removed.

    A Comprehensive Review
    After receiving some outrageous quotes and a very stretched contractor base, I decided to do the whole thing myself - approx 1400 sqft of 20-year old occasionally-watersealed deck. - Did the project over the course of a month (April/May) around perfect weather conditions. Approximately 8 full days. - Prep of old deck was Powerwashed, Stripped, Powerwashed, Cleaned, Powerwashed, and actually hit with a wire brush then vacuumed. - Painted the entire deck with a 4" brush then topped with a coarse roller. Painted all vertical services (and some rough spots) with a brush. It was absolutely backbreaking work. It came out beautiful..... and after a full Summer it still looks brand-new. Most importantly - and TBD - I hope that it lasts the 10 years advertised. Feel free to ask any questions....

      Sealeant is NOT "clear"
      As with so many other reviews that I wish I had read before buying this product (who expects something labeled “clear” to actually be orange!?), this sealant is NOT CLEAR. I don’t get it. I now have a kid’s clubhouse that is painted gray with a semi-transparent orange film overtop and now I have to repaint the whole thing because it looks horrible. There are other reviews like this from 2015. How is this still a problem? It is absolutely waterproof. But it's ORANGE not “clear”. xa

        Ugh
        Reads review of a different Olympic product but wound up with this one. ‘Clear’ is not a subjective word, and this is not clear but yellow, like wood glue. Turned my freshly planed redwood fencing into a muddy orange/red I’m very unhappy about. It doesn’t enhance wood grain like an oil but hides it under a pasty film. Too late now, never again for this brand. If you do get stuck with this, be sure your application is perfect, there’s no going back to even out coverage and any runs will be orange. I went to Home Depot for more Thompson’s oil seal, but no longer stocked and since HD put all the locally owned hardware stores out of business there was no other choice.

          Excellent Golden tone
          It took a long preparation to rebuild clean, sand and apply sealant to my deck. It has a beautiful look of natural wood. My wife and Ilikes be it.

            This is a great product for sealing outdoor decks I have two decks, a dock and several walkways. The sealer is easy to apply with a brush or short nap roller. The finished product looks amazing.

            Great finish
            I read the reviews claiming this turned their wood yellow. Well, for me, it turned my boring redwood fence into a red and honey colored masterpiece. I applied two coats with a Wagner sprayer (about six inches away) and I’m thrilled with the result. It has a light sheen and completely repels water. The spray from the sprinklers just rolls off the fence. Be aware that this is not clear. It does have a honey tone to it, but it looks great.

              Read the Reviews - THIS IS NOT/NOT CLEAR
              As so many people have already written, this product is not/not "clear" and has not been for years. I wish I had read the reviews before I purchased this. We (as others have) assumed we would apply this golden honey colored sealant and it would dry clear. NOPE! In the end it's not horrible, but it's definitely not what we were going for. Why why why after so many years and so many complaints would they continue to label something as "clear" when CLEARLY it is not??? Have to give one star for that, regardless of the quality/value.
