### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Work Very Well!
  

*by J***L on Reviewed in the United States on September 8, 2019*

I have used the regular Thompsons wood  product on decks in the past and find it to have the best long term effectiveness for UV and wood preservation. Thompsons will not add the short term richness of an oil type product but after a year or two it will continue to keep the moisture out of the wood and preserve better in my experience. The Thompsons Advanced in this review was for a 4 year old dock on a lake in Minnesota that was part of a house purchase. The dock was a cedar wood dock that was looking very rough and had no previous treatment.  I did much research as this is a big dock and I wanted to use the best product possible for the best long term results as the labor cost was more then the product cost and don’t want to redo this very often. My bother in law and  nephew did the work. It started with a professional power wash and then a power sander on the troubled spots and bench. Then they applied the Thompsons with a roller and brushed it in. It is very easy to work with and although they say the wood can be damp we have given it time to dry well and had perfect dry weather to apply. The product says it is clear but it have a yellow/orange tint to it which I liked because it added a slight cedar wood looking color to the freshly pressure washed wood. Some reviews commented on it making for a slippery surface but this was not the case in my experience.(I wonder if they put on two coats that is not recommended in the instructions?). The dock looks beautiful and when it rains it totally beads up and does not absorb a drop of water. i gave it 4 stars on longevity because it has only been one year but if its like my past experience. With Thompsons I will go back and  change it to 5 after a few years if it holds up well. I have a before and after picture of the dock, not the best pictures but I was to lazy to go take more. Everyone that see the dock comments on how nice it looks especially the ones that saw it before. I like the product wary much and feel confident that it will hold up well. Hope this help you.  Jim

    Great product.  My deck will be nicer than my inside floors.
  

*by G***C on Reviewed in the United States on August 13, 2018*

I love the way this came out on my new deck wood.  The treatment out of the jug looks more like a fancy flavored coffee creamer than something that's clear.  The application is a little like a giant decoupage project.  You smooth this out to a thin coat and it dries nearly clear.  It does make the wood a shade darker, but it looks really nice.  It also adds a little bit of a sheen that I like too.  I hope it holds up longer than a couple of years.I've completed my first half of the deck.  I have work that's going to be done over the other half soon.  Once that's done I'll finish the rest of my project.  The product instructions said to treat right away on new wood.  I waited a couple of weeks for it to stop raining for a few days in a row.  I used a half gallon on the half that's been treated so I should be able to finish the rest with the remaining product that I have.

    Great product, exactly as advertised.
  

*by D***. on Reviewed in the United States on May 24, 2020*

Applied to a 1 year old 10’ x 20’ deck with railings in August 2018.  Took almost exactly 1 jug and lasted just around 20 months vs the advertised 24 months.  However, I did not power wash it and I applied it on a hot sunny day, so I think I’m to blame for how long it lasted.  It went on very easy with a cheap outdoor stain brush.  In the first 12-18 months after application, water would bead so much that the water would remain on the deck long after everything else outside was dry.  Getting ready to reapply now (May 2020) and I’m going to power wash it and apply during the shady part of the day.  I’ve used other stains and paints in the past, and I like this for its ease of use, low cost, and performance.
