Customer Questions & Answers

Can you use this stain on pressure-treated wood?

Asked by: David
Yes. But read the directions first. I would let the pressure treated wood sit for a couple of months before applying a stain if it was me.

Does this product help reduce splintering of the wood? Does it fill small gaps in wood?

Asked by: jess
Hello. Our products are waterproofers, which seal out moisture. They don't reduce splintering. Also, our products are meant to be applied thinly and are not thick enough to fill in small gaps in the wood. Regards, Thompson's Customer Support

Is it water based or oil based stain?

I have old based stained deck and would continue like to use oil base stain / sealer. Is Thompson's WaterSeal Waterproofing Stain Semi-Transparent Maple Brown oil based stain ? Thanks!
Asked by: Joe
This is a water based product. That is one of the features that I liked the most about it.

Can you latex paint over the top of this semi-transparent stain?

Need to paint each picnic table with a different primary color
Asked by: wasteofmoney1
This is a water based product. If the stain is solidly adhering to the wood then you should be able to use a good latex based paint over it.

1 gal. Semi-Transparent Maple Brown Waterproofing Stain is rated 4.2 out of 5 by 21.
Rated 5 out of 5 by from Best Deck Finish Product We used Thompson's Water Seal Stain on a very large deck at a previous house that we owned and had great experience with it. At our current house we tried a new deck coating product, and it did not perform well at all. We have scraped all of that off and gone back with this Thompson's Water Seal. I love this product. I won't ever use another deck finish product again. The directions are very clear and easy to follow. The 1 gallon can works great, and pours well. The stain is easy to apply. Clean up directions are easy to follow. I simply don't have any negative experiences with this product to report.

Rated 1 out of 5 by from I live in Minnesota. Last year August 2016, I decided to use this product for staining my deck. I... I live in Minnesota. Last year August 2016, I decided to use this product for staining my deck. I put on 3 coats and followed the directions to a T. The product didn't even survive the winter before it started to flake off. I contacted Thompsons and they gave me the run around asking if I did the water test (Where you dump water on the deck to see if it beads up or soaks in. It needs to soak in to prove that it is porous enough to accept stain) and questioned me about the other directions. I told the guy who I was corresponding with that of course I followed the directions because I only wanted to do this once and have it last a few years. The guy said that the company stands by their product and that I would just have to send in the original receipt and they would gladly refund me. Who this day in age keeps a receipt for stain or paint? The answer is me from now on. I am not really as angry about the money as I am about the fact that I am going to have to redo this time consuming job. Not only will I have to restain, I have to strip off this inferior product adding more time and money. I will never again use a Thompson's product. Not only is their product inferior in the northern states, their customer service leave a lot to be desired. I bought 5 cans of this product and spent 2 weeks prepping and working on this project, since I have a large wrap around deck, just to have to do it again not even a year later. Unacceptable!

Rated 5 out of 5 by from Good stuff and good for 2~5 years depending on surface. The hardest part of doing this job is getting the weather and my available time to coincide. Cleaning up the overgrowth of plants takes more time than application. Perhaps Spring or Fall would probably be the best time to apply, when the plants can be trimmed back or not growing... Color / tone form gallon to gallon is good. They matched quite well. We used rollers, brushes and tried a 'garden sprayer' for the application. I used a 'long nap' 6" rough surface roller, and 2" 'disposable' brushes. No point in using a quality +$25 brush on the rough wood surface. I purchased a "Flo Master 1125d" specifically for this task last year. If you use a sprayer, make sure is is compatible for this task. The one I purchased at HomeDepot last year that was listed as suitable for this application. There are pictures of the paint/stain cans on the box. It proved absolutely unusable for this application; it was more of a mess than it's worth. My daughter, in her words; "I would love to write a burning review of that item", as she cleaned it.. We found the best method was: The long nap roller (with an extension pole/stick) was the fastest for the face boards, and brush to apply the product to end grain and between the boards. Pictures attached show a small section of the fence before/after. An aged, (+10 year old) section of fence (~14 feet long / 200 sq/ft) sucked in the preservative and needed almost a gallon. Obviously, your mileage will vary, perhaps I'm over applying.... But only another ~ 70' to go...

Rated 5 out of 5 by from Very easy to apply, dries fast Like that this is more of a thin paste than just a liquid, it makes it very easy to apply with a brush. We applied it to brand new pressure treated wood on a trailer deck, and it looks great. I did two boards at a time and don't see any brush marks. Not sure how long it will last on a trailer but says 4 yrs on a deck so will probably depend on how hard we use the trailer. You can see a little of the green on the pressure treated wood since this is a semi transparent. I also did a regular 2x4 piece to see the color difference and it wasn't very different, just a bit lighter on the untreated wood. Overall very pleased with the end product. Love the easy water cleanup.

Rated 5 out of 5 by from Thompsons Stain maple brown I have long been a fan of Thompson's waterseal and have used it on my deck for over 25 years. After power washing my deck back to the original wood my wife decided she wanted to use a atain instead of clear.the brown maple went on very easily using a long handle and flat deck brush. It covered very easily and because our temperatures were in the 80s it took only 15 minutes for it to dry and only one coat was needed to get full coverage. And it only needs to be repeated every four years.

Rated 5 out of 5 by from good product I recommend this waterproofing stain. For best results read and follow the instructions thoroughly. Start by preparing the surface so the stain adheres. My deck is less than 1 year old is in the sun most of the day. Once ready to go it rolled on smoothly and soaked in quickly. Coverage depends on how you apply the product. The color is light so the grain shows.

Rated 5 out of 5 by from Great easy to use stain This stain was very easy to use. After I power washed my deck I applied the stain with a brush. It applied easily and covered very well. I was very happy with the maple brown color , very similar to the color I had before. The only problem I had was that my deck was older and had some areas where the old stain had worn off and I should have chosen a solid color stain as opposed to the semi-transparent stain. Certainly not a fault of the stain I used but I had some areas where the bare spots on the deck showed lighter than the rest of the deck. I did end up doing a second coat and it covered very well but with the older deck surface a solid color stain would have been better. All in all the deck came out very nice, good coverage and great color. Clean up was a snap with just water and soap. Dried quickly as well and water beads up very nicely on the deck. I would recommend Thompson's waterproofing stain to anyone looking to stain their deck.

Rated 5 out of 5 by from Easy to work with We are very happy with this product. We used it after letting the wood dry for a day. The product was easy to use and the color was beautiful! It's only been a month so we have yet to see how long the stain will last.
