Rated 5.0 out of 5.0 by Love this product We love this cedar color. I was afraid it would be to red but it is just right. My poles were starting to get dark so we decided to stain them. I've used Thompson clear water sealer before so we decided to give their stain a try. It goes on very easy and a little goes a long way. Easy clean up also since it is water based. One coat will be plenty. And I am glad you can still see the wood grain. May 2, 2015
Rated 5.0 out of 5.0 by Truly satisfied with this stain This stain gave a new life to our deck, shed ramp, shed base frame and our mail post. Directions labeled on the container were very easy to follow. In fact, I did not have to do any prep work as it requires no primer. I used the spray gun on the deck, a roller on the ramp and brush on the mail post. It worked well with all three. We stained 2 coats on the deck to get a bit dark stain since it gets the sun all day. Talking about mail post, the stain looks so good that our neighbors thought we got a new post. Knowing the brand, I am not much worried about longevity. Go buy it, you will like it. July 13, 2014
Rated 5.0 out of 5.0 by Water Proof and Refresh the Look of Your Outdoor Wood I chose this product because my fences were looking pretty bad and being attacked by mason bees every spring. I decided to go with Woodland Cedar because I love cedar. I think clear would have been more the look I wanted, but I find that transparent looks very nice. It's a great way to update and refresh the look of your out door wood features, while water proofing it as well. I'm not sure if it's deterring the mason bees, but it's definitely repelling the water. I found this product went on even and smoothly and I was able to complete each fence section with ease.

Rated 4.0 out of 5.0 by Nice Transparent Color I used a brush to apply this Thompson transparent stain to treated wood that was about 2 years old. It had never been treated and I knew I needed to protect it from the elements, but also wanted to add some color. It turned out just as I had planed. The stain adds color and protection without covering the woodgrain, (see picture). It was a little hard to apply to vertical surfaces since it is the consistency of water, so put down ground protection if needed. June 11, 2015
Rated 5.0 out of 5.0 by Beautified my 1-year old deck This was easy to apply with roller and brush and dries quickly. Clean up is easy with soap and water. It took 1.5 gallons to cover my 12ft x 12ft deck (144 sq.ft),despite the specifications saying a gallon will cover 300 sq.ft. Stain finish was slightly darker than I expected but very pleasing. The water sealing is promised to last 3 years on deck surface (horizontal) and 4 years on posts/fences (vertical). See the pictures for before and after comparison. I pressure washed the deck but used no chemicals, just water, in the morning. Then in the evening I applied the waterseal/transparent stain (the directions say shouldn’t be applied in direct sunlight, hence, evening). This proved to be a definite improvement of my deck, which is one-year old. June 1, 2014
Rated 5.0 out of 5.0 by Great Product I am very happy with the result. The price is awesome 50% cheaper than other products. My deck looks amazing and from far view it looks like a resin deck. Also a few days after applying the stain it rained so hard and you can see how the water was repelled. June 12, 2015
Rated 5.0 out of 5.0 by I couldn't be happier! I bought 1 gallon of this to stain and reseal all the wood on our 8'x9' hot tub. After stripping the tub with a pressure washer and letting it dry for a day, I got started. I was a little worried when I poured it into my paint tray. It was almost a flesh color. I was even more worried when I made the first brush stroke and that fleshy color was all over the clean wood. After about 15 minutes though, the cedar color set in and it is absolutely gorgeous. Coverage was super, I did one coat and see no need for a second one. I did the entire hot tub and still have about half a gallon left. I applied this with a cheap economy 4" paint brush and it worked perfectly. So easy that I went ahead and did the picnic table really quick while I was at it. This is one of the easiest to use products I've used in a long time. I highly recommend it. May 8, 2014
Rated 5.0 out of 5.0 by Does It's Job I applied the stain with a roller on the top of the table but it left bubbles, so I switched over to a brush and it made a world of a difference. The stain looks really good and works perfectly. It rained later in the day and water did not soak in. May 26, 2015
