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 2.9 out of 5 by 69.
Rated 3 out of 5 by from Has the formula changed? I had some 5 or maybe 10 year old Thompson water seal. I put it on with my old Thomspon sprayer and it worked great. However, I swear the sealer was clear. Purchase a new can of sealer and it was milky and was very difficult to spary on my fence. The application was very blotchy. It look terrible but as it dried the apperance improved. Still have some sticky areas and wasted a lot of sealer because of how it sprayed.. I still recommend Thompson's water sealer because I have used it over 30 years with no problem. Makes me wonder if its my sprayer or if its the product. I may have to do the fence again to ensure proper coverage with a new sprayer and product.

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 5 out of 5 by from Finally waterproofed Due to many years of illness, sealing of our deck never got done. Just found someone to complete the process after a good pressure cleaning. This poor abused 10 year old deck is now looking like it was just built and sealed. Am so happy with how Thompson's performed.
Date published: 2018-11-15
Rated 1 out of 5 by from Very disappointed We power washed and cleaned our deck and it looked brand new. We waited a day to be sure it was dry and applied this clear seal and I am so disappointed. This was 3 days of work and it looks horrible!! I have used this product for 30 years and have always loved the way it brightened and refreshed our deck. How do we fix this?
Date published: 2020-06-04
Rated 1 out of 5 by from Thompson Needs to Develop a New Formula My experience is the same as the other recent reviews, i.e. leaves the concrete sticky and blotchy. Used two gallons with a garden sprayer as recommended on the can. When I ran out and had to go purchase another gallon, the nearest store didn’t carry Thompson’s. Purchased Olympic and it worked perfectly. That is the only part of my concrete that looks good. So, it appears that it is possible to develop a formula that works, even with the VOC restrictions. This is not an acceptable product.

Rated 4 out of 5 by from Good waterproof coverage I bought this product 2 years ago. I have used it on the wood plank floor to my trailer. It has been great protection for the wood in my trailer.
Date published: 2018-11-06
Rated 1 out of 5 by from Garbage Don't waste your money. No longer clear. A white pastey mix that plugs the sprayer and is way lighter finish than the same jug I bought 2 years ago. Doesn't apply very easily and will require a second coat. Totally not impressed! What a waste of time and money!!!
Date published: 2019-08-04
Rated 1 out of 5 by from Tackiness I applied this product according to the instructions. my surface was acid stained concrete which is 7 years old. I applied the sealer with a roller and the temperature was approximately 85 degrees. After over 48 hours the sealer was tacky, so much so that you could not walk on the surface. Pressure washing twice with a detergent had a minimum effect. Only after two more cleanings with a degreaser was I able to walk on the surface with still some tacky spots which needed attention. I have used other water based concrete sealers before which have all had very fast drying times and did not remain tacky even after several applications within the same day. Always used Thompson's products in the past and I thought I would revisit the product line. I am sorry I did.
