Customer Questions & Answers

Can I use it on brick pavers

Can this be used a stained fence when not sure what was used on it before

Asked by: mona
Hello. This product is meant to be used by itself, as are our all of our products. To determine if the surface is able to accept a coat of our product, you will need to first test your surface by performing a "splash test." This will tell you if the surface is porous enough to properly absorb our products. The test is done by splashing some water on the wood. The water will do one of two things: 1.) Absorb into the surface making it slightly darker. This is a sign that our product will effectively absorb into the surface and you can apply our product successfully. 2. ) Water will puddle or just run off. This means that the surface is not very absorbent 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. Regards, Thompson’s WaterSeal Customer Support

5 gal. Sequoia Red Transparent Waterproofing Stain is rated 4.1 out of 5 by 15.
Rated 5 out of 5 by from Great product I have a 27 year old deck of wood . It has never been treated with any preservative and was looking pretty grungy. I power washed it and waited a week for it to dry. I then applied the water seal with a hand pump sprayer. @ days later we had a significant rain fall and the water just beaded up. I also used it on a glider with wooden slats. After cleaning it and spraying with the water seal it looked like new.

Rated 5 out of 5 by from Easy to use, but not quite as "red" as I expected This is a beautiful color, but not quite as red as I expected. I should have guessed, after using the product, I looked up "sequoia" and the color of the stain is similar to that of the sequoia tree-- which is more of an orange-red. It's still super beautiful, and I'm very happy with the outcome of my project. I used this waterproofing stain of my child's homemade outdoor kitchen. In my pictures you can see the before and after. The color works great for a natural look outside, while still protecting the wood. Be sure to double check your color, but this is a good option if you don't need an exact match for anything and are looking for a natural orange-red look!

Rated 4 out of 5 by from Fantastic Product This Thompson stain and seal applys so easily with my pressure pump sprayer and clean up is a total breeze due to water clean up. I got the exact color that I wanted by using the shade chart with no problem and the pricing is unbelievable!

Rated 5 out of 5 by from Renewed old lawn furniture This was easy to apply with brush and dries quickly. Clean up is easy with soap and water. It took about 0.5 gallons to cover 5 pieces of lawn furniture. 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 furniture but used no chemicals, just water. Then I applied the waterseal/transparent stain (the directions say shouldn’t be applied in direct sunlight). The small benches had an old finish (presumably some sort of shellac or polyurethane finish) that prevented the water seal to absorb into the wood so the stain didn’t really take. However, this proved to be a definite improvement to my lawn furniture, which is probably 20 years old.

Rated 5 out of 5 by from Great Waterproofing Stain Thompsons has a complete line of quality products. This one is no different, Applies easily with either brush,rag, pump sprayer.... I used my small hand pump sprayer and then wiped in with a rag to ensure complete coverage. after about 5 minutes giving it a final wipe down. one Thing you must watch out for when applying, be careful not to leave any runs... they will dry hard and you will have to sand them out. the stain must be well shaken and comes out of the can in a milky liquid,, It also looked pink and not at all like the color, But when all was said and done it looked great on the finished product and color matched fine. Im sure you will be pleased and aside from finishing or refinishing your project you will have a nice looking project that has been waterproofed and last much longer because of it
