I purchased a Yardistry Pavilion several months. In checking with Yardistry, they recommend Thompson's water based sealant. After reviewing your reviews, I don't see very many happy customers. Is this the right product for this product?

I have a insulated garage. I just want to be extra sure that no moisture go from outside brick wall to the inside of wall. Would it work for this purpose?

Asked by: GarageGod
Hello. You can use our product on the outside of the brick wall, provided it has no existing coating/product on it. Our product should seal the outside surface against any moisture or water. It will not seal any water from the inside wall though. Regards, Thompson’s WaterSeal Customer Support

I've coated my concrete with epoxy/color chips, can this be applied on top of it, for a seal (want to seal the extra loose chips). Once applied is the product slippery?

Asked by: Duffman
I believe this product needs to be applied to clean or bare wood. I would choose a thicker product for that purpose myself.

Thompson's WaterSealer Waterproofer - Multi-Surface - Clear - 3.78-L is rated 2.3 out of 5 by 15.
Rated 5 out of 5 by from Very Effective on Older Concrete Pavers I was looking for a product to bring some life and colour back to an older patio made of concrete pavers. I had tried other products with limited success. Thompson's Multi-Surface did the trick. It is cheap and very effective. It improved the colour while sealing it. To prepare all I did was used a pressure washer. I tried to roll it on with limited success so quickly discovered that spraying it with a pump sprayer worked best. I did find it useful to use a paint roller to even out the spray. Two coats were necessary. There are also good videos on Youtube to show you how to apply.the product. I have also found that the product may go a little milky if rained upon early after the application but this will disappear

Rated 3 out of 5 by from Not as happy as usual I’ve used Thompson’s deck sealer many times. On my fences and decks. They’ve always absorbed really well, and lasted a few years before starting to sort of fade away. Last year I did my deck, and we had a very mild winter. It was brand new wood a year old I left it almost 2 years before treating it. I cleaned it well let it dry thoroughly and then use the sealer. Now, it looks terrible. And I have to redo it Please advise me on how to redo it. Thank you. Very strange because the upper deck seems to be only a couple of spots. I’m just very disappointed. This has never happened before.Not as happy as usual

Rated 4 out of 5 by from It is a sealer! Unlike the water based garbage this product is solvent based and I used it on a brick-lock patio. I used a masonary roller and finished with a brush tip. A bit of a pain to apply compared to the original formula but it sank right in and works great. No wierd patchy spots or streaks but paints more like a gel than a liquid hence the brush to push it into the poors of the bricks. I am happy with this product.

Rated 4 out of 5 by from Great deck water sealer. My huge deck was built in 1988 and I have been water sealing my deck every two years since it was built. I have always used Thompson's water seal. The deck still looks new when I pressure wash it and then water seal it.

Rated 1 out of 5 by from problematic I built a deck using 2x6 PT(green) material. let it cure/dry for 2 seasons and then applied the clear waterseal every year after . Knots started raising, had to sand them down and decided to put the pre-tinted coloured version over the clear, as it is Thompson is would be the best choice for compatability(adhesion). Every year 50% plus or minus chips off and requires redoing at the cost of 3 gallons. In addition the colour on the can (Acorn Brown) appears much darker on the deck. Wife picked out the colour (really unhappy as is gets too hot) , don't want to further complicate things by putting another colour/product over it, don't want to strip/sand it down. Any suggestions? Very dissapointed in the adhesion of the product. Just a further note I have been a Journeyman painter since 1985 and used multiple products for a wide range of applications.

Rated 1 out of 5 by from Not a good product I bought Thompson's waterseal Multi surface sealer and did follow the instructions but the product dried white and streaky. It's not the 24 dollars for the can I'm out its the 5 hours of prep that we have to do again . It's is a no buy even if it's the cheaper can of product. Teck seal is the way to go , it's 55 dollars a can but works amazingly. Don't buy Thompson's, should have known better.

Rated 1 out of 5 by from Terrible product, worse support. I bought this sealer to finish off my new deck. Well great job Thompson's, you ruined a $15,000 deck.It looks awful, and the support team told me there is nothing I can do about it short of sanding it all down, or replacing all the Cedar boards. DO NOT BUY THIS PRODUCT.

Rated 1 out of 5 by from Waste of time and money!!! Its too bad I have to rate it one star, should be negative 5! This stuff is garbage! Built a beautiful Cedar deck and made the mistake of coating it with this. Followed all the directions, cleaner, brushes, etc! It started coming off before the summer was over! By the next summer more of it was gone. The only areas that stayed are the ones that were covered by matts, like where BBQ was and other areas out of direct sunlight. Emailed company to inform them and never heard back! We tried using stripper to remove it but wound up having to sand the crap that was still there. The areas where it actually stayed we had to disassemble and run through a planer! Why didn’t it stay that well everywhere???? So if you decide to use this crap and your deck is in direct sunlight then cover the whole thing and don’t use it for the first two years! Then maybe it won’t wind up looking like crap like ours did!
