After waterproofing on the outside of the basement and repairing cracks on the inside, I used Thoroseal for an additional layer of moisture proofing but mostly to conceal imperfections in the walls.
I spent two days scraping and one day repairing mortar in preparation. I sprayed any bare block or mortar with a water bottle before applying, although most of the walls still had paint on them. I applied a very thick coat of Thoroseal with a masonry brush. It was difficult at first to find the correct pancake batter consistency for the best application. It was best to add the thick coat and smooth it immediately then knock off any clunkers after they dried. Brushing over recent work would tend to pull it off the wall. Again, I was coating over paint which Thoroseal does not recommend.
After one coat, I am getting some yellow efflorescence bleeding through so I will be adding a second coat, which Thoroseal recommends. I expect more to bleed through even after the second coat so I will plan on painting too.
This took longer than I thought to apply and I was tired by the end of the day. Painting with pancake batter is certainly more exhausting than painting with paint.
Overall I am pleased with the finish on my walls. I was hoping to get away with one coat instead of two, but I would like to do this project right this one time so I will be buying more today.

Rated 4 out of 5Â by John Works well.... but you'll work hard applying it
This product is an affordable, effective water-block for basement walls, but be prepared to work hard using it.
This is a powder that you need to mix..... it's really more like a cement than a paint. You almost need a trowel to put it on..... but don't use a trowel, use a wide brush.
If you're looking for n easy-to-apply solution. This isn't it. However, it does a better job of blocking water than a paint

Rated 5 out of 5Â by LiNiCoMnO2 Great product
I have used Thoroseal on my 3 previous homes and have been really pleased with the product. My last home was 50 yrs old and had some serious water leaks in the basement. I first used a bonding cement then finished with Thoroseal and the result was like a new foundation, everything was dry and clean. I have applied it to my current home that is new construction and I do not have any moisture problems, even in the summer. I recommend Thoroseal to anyone trying to reduce moisture problems in their basement. If you have serious cracks, you will need a bonding cement first.

Rated 5 out of 5 Great product for difficult challanges
I have a home with a walk out basement built on a lime stone outcrop. The walls behind the furnace and washer dryer were more akin to a dungeon then a modern day basement. After trying several of the paint based products to address the color, dampness, and dust, I used SUPER THOROSEAL.
The oil based paint like products gave me a tremendous headache and the water based ones didn't give me much confidence as a water seal.
The powder form of this product actually took advantage wet nature of the space and the thin or thick of the mix is up to you. A thinner mix on the irregular surface of my walls really brightened up the space. Any blemishes over the years were either wiped away or covered over with a quick brush on of this product.
The only caution I would give is the need to mix this powder outside.to avoid breathing in the dust while mixing with water.

Rated 1 out of 5Â by JoeVAr Poor Product and even worse customer service
I would never recommend nor would I ever use any Throseal product again. They are really good at answering your pre-sales questions but they will let you hang out to dry if you have a problem after using their product. I used their product as directed yet still got water leakage in my basement. I requested assistance as well as later requesting a refund. All of my requests went unanswered.
