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

Thompson's WaterSealer Waterproofer - Multi-Surface - Clear - 3.78-L is rated 3.3 out of 5 by 131.
Rated 1 out of 5 by from Garbage! Long couple days pressure washing our concrete driveway which made it look incredible only to use this crappy sealer that made it look horrible! Wish I would have seen these reviews first. So now we are stuck with this stained driveway and to top it off it rained today and it doesn’t even bead water. It is a complete garbage product and I will never purchase it again, lesson learned!

Rated 4 out of 5 by from Perfect for backyard deck and the concrete walkway I use this for my backyard deck and the concrete walkway. This works perfect for my needs as I have two different surfaces to process.
Date published: 2024-03-05
Rated 1 out of 5 by from Don't use it on concrete pavers I wish that I had read these reviews before buying this product. It has destroyed my patio. I've spent the last 2 weekends trying to clean it with mineral spirits and a pressure washer, per their suggestion, and it is still a mess.
Date published: 2023-11-15
Rated 5 out of 5 by from Fantastic product I purchased product a few weeks ago to seal a picnic table. Thompson is a product I’ve relied on to protect my outside items
Date published: 2023-09-30
Rated 1 out of 5 by from This is absolutely the worst product on the market This is absolutely the worst product on the market for concrete! This is the first time I have used a Thompson's product and will never use any of their products again, for any reason. I finished power washing our front entry sidewalk and a large portion of our driveway, to prepare for sealing. I applied the remainder of a GOOD sealer I had on hand to the majority of the front entry sidewalk. The building supply company where I bought the GOOD sealer was not open, so I decided to try Thompson's Multi-Surface, because it states on the can that it dries clear. This product DOES NOT dry clear and has ruined our driveway! I should have read all of the complaints and reviewed the pictures before buying. With so many complaints and customer losses of hundreds to thousands of dollars, I'm surprised that a class action lawsuit has not been filed against Thompson"s. Something worth considering. I would like a refund, so I can then take that money to buy something to remove the horrible Thompson's product from my driveway.
Date published: 2023-09-29
Rated 1 out of 5 by from This is water based not oil based! I ran out of oil based Thompson's and bought "Clear Multi-surface Waterproofer. NO WHERE ON THE LABEL DOES IT INDICATE THAT THIS IS WATER BASED SEALER! I tried using it anyway but it dried lighter and blotchy. It doesn't match the oil based sealer. Now I will need to remove the water based sealer and reseal the deck using oil based sealer. I guess I'll have to find another brand of sealer. Thompson's needs better labeling to inform the purchaser that this is water based sealer.

Rated 2 out of 5 by from Not same clear wood affect as wood only sealer. Not the same nice wood color as the one just for wood. This one is white and looks watery chalking after applied.
Date published: 2023-09-21
Rated 2 out of 5 by from Thompson's Never Dry Sealer seals good IF you can get it thin enough to apply, if too thick it will take weeks to dry and will still be a little tacky after a month, this is not the "Original Thompson's" which is a good product however I would not recommend the all purpose.
