Don’t buy! Deserves zero stars!!

26 days ago
Don’t do it! Save yourself lots of time and money! I spent the better part of a week last summer prepping my deck and staining it. It looked amazing. After the first winter, the stain literally faded away in large areas. I’m now left with a huge disaster and a huge expense to fix it. Completely devastating.

No, I do not recommend this product.

good sealer, but did not cover as much as claimed.
Helpful?

Colour not like the sample!

11 months ago
We have always used Thompsons waterseal and have been satisfied with the results. However, this time we chose the Semi-transparent in Chestnut brown according to the photos shown on the website. The colour is not brown, it is red, like a dark mahogany. I know when applying the colour looks different than it will when dry, so didnt think too much of it. But when dry it is very red. Not at all like the sample colour , not even close. Very disappointed and nothing we can do about it now but to live with this colour.

Not good for sun / weather exposed wood

a year ago
Its a 1 star in the sun, and 4 star in the shade product. So if your deck is covered it looks good, And when it first goes on it looks good, however on any wood facing south west, which is where it gets the most sun/rain/weather, doesnt even last a year. I stained my deck last May 2024, and now in April of 2025 anything that wasnt covered needs completely redone, after only 11 months in Ohio.

No, I do not recommend this product.

Thank you for taking the time to review the Semi Transparent Stain. The Thompson's products are penetrants, and should not peel or flake off. If the product is peeling, the surface was not porous enough to accept the stain. We generally recommend doing a "splash test" prior to application to ensure the surface will accept our product. At this point you can either sand the surface or use a power washer in conjunction with a chemical stripper to remove all peeling or flaking areas. Before you apply any more product, I would first test your surface by performing a "splash test." This is done by splashing some water on the surface. The water will do one of two things: *Absorb into the surface making it slightly darker. This is a sign that another coat of product will effectively absorb into the surface and you can apply our product successfully. *Water will puddle or just run off. This means that the surface is already sealed and our products will just form an oily, tacky layer on top. We would not recommend applying our products at this time. As long as the water test shows that the surface is absorbent, then you can proceed to perform a test area. This is important for two reasons -- it will help you learn how much product to apply before the surface is saturated and also show you what degree of discoloration will occur. As you will notice, once the surface has absorbed a certain amount of our product, then the remaining waterproofer just sits on the surface and can lead to oiliness, blotchiness, or discoloration. For this reason we recommend test areas to determine the porosity of the substrate and how much product you can apply in any given area. If you would like to discuss your review further or have any questions, please contact us directly at 1-800-367-6297 or info@cbgbrandreview.com. Sincerely, L.T., Digital Care Team

Deck stain project 2024

a year ago
Needed to stain my deck and got a crazy idea to tri-color it. I'm 61 years old and love this product.
