Thompson's Waterseal cleans up easily with mineral spirits followed by soap and water. If you do this the tools you use can be dependably used again.

Dear Dale,
Instructions for use indicate that a light coating for Thompson's Waterseal is all one needs to do the job. However, it also indicates that concrete, brick and masonry surfaces must be thoroughly cleaned prior to application with a concrete cleaner according to the directions and cautions on the cleaner. Concrete that has a smooth, flat finish must be opened for proper penetration by Thomson's Waterseal. This should be done using a concrete etch product following concrete etching use instructions carefully ensuring thorough rinsing and removal of the etching solution. Then allow the concrete to dry a minimum of 72 hours after etching before applying the Waterseal. I'm sorry you had the problem. I know things like this can be frustrating. I hope this helps.

Answer: 
Your results are directly related to applying it too thick.
You could try to use cleaner and powerwash it again however, I think you may have better results using something like muriatic acid then powerwashing it.

It sounds like a humiidity issue. If you are having high humidity levels where you live and had applied the waterproofing too thick then it will take added time to dry thoroughly.

Dear oh, Thompson's Water Seal is a wax-based product. Bear that in mind. It is not a permanent or long term coating such as paint or stain. You will likely need to re-apply every two years. Also note that this coating is not in solution...technically it is a dispersion which will settle in the can over time. Most likely you will need to stir the product i.e. with a stick of wood - something that will reach down to the bottom of the can. You will need to stir it a lot to get the wax back into dispersion in order to get it to a state where it will give you a uniform coating.
The waterproofing comes from the water repellent characteristics of the wax. Out of the can (after thorough stirring) it will soak into the wood providing a surface where water will bead up. Gradually, the wax will continue to penetrate deeper into the wood while some of it will evaporate especially with direct sunlight. Hence the need to re-apply periodically.
In my case, nearly ALL of the wax was in the bottom two inches of the can. Since the 5 gallon can is 'closed head' it is much more difficult to stir it to make the coating uniform for application. Plan to spend some time stirring. Read Less

Thompson's Waterseal will seal the concrete and protect it from water. This means that it would probably protect from drawing damp through the concrete under the cabinets. Surface water, however, from washing, flooding or condensation under the cabinets could still be a problem.

If it were my garage I would definitely treat that floor and check from time to time for condensation. I reapply mine every two years.

Answer: 
Yes, you can use this for your intended purpose however, seeing as it's a multi-surface waterproffer and not a purposed concrete sealer only, you would probably look at putting this down again every year, or 18-months.
Following that, it should work fine for you.

Hello Pdude, this would work however there are other products for the exact thing you are trying to do & also would be a bit less expensive. I am assuming you don't have the Thompson's Water Seal yet... If you do then prep is very important for concrete use. For Concrete/Brick/Masonry Surfaces must be thoroughly cleaned prior to application with a concrete cleaner applied according to label directions and cautions. Concrete that has a smooth, flat finish must be opened for proper penetration. This should be done using a concrete etch product. Follow etching product use instructions carefully and ensure thorough rinsing and removal of etching solution. Allow concrete to dry a minimum of 72 hours after etching before applying a waterproofer.
I would use BEHR Premium 1-gal. Protector and Waterproofer to seal underneath the cabinets. I have provided a link below. This stuff is good as it penetrates into the concrete to form a waterproof barrier & is reported to last 10 years. I hope this answered your question & helped.

CUSTOMER REVIEWS

Rated 2.7 out of 5 by 80 reviewers.
Rated 4.0 out of 5.0 by Clearly effective This sealer was very easy to use. There was almost no change to the color of the deck with the application. Its effectiveness is evident when it rains though. Water beads dramatically on the surface. After reading the reviews of others I stayed off the surface for two days to allow to cure. When I checked after that time period the surface was not tacky to the touch. Overall happy with the product, and its application. I would recommend it. May 3, 2016
Rated 5.0 out of 5.0 by Thompson's WaterSeal Clear Multi-Surface Waterproofer I use the Thompson's® WaterSeal® Multi-Surface Waterproofer on the back yard fence. I like the clear so the wood can gray naturally. The water proofer sprays on easily for quick application. You can also brush or roll on, I just prefer to spray. The 5 gallon can covers up to 1000 square feet so the entire fence can be covered with one container front and back. I usually apply on 2 forecasted sunny days because you need to allow 24 hours for drying. March 18, 2016
Rated 5.0 out of 5.0 by Keeps my brick fieplaces clean and dry When I was prepping my house for paint I decided to pressure wash the exterior brick on my two fireplaces. I didn't realize how dirty and dull they had become. Once they dried I grabbed my pump sprayer I use for staining my fence and deck and loaded the waterproofer. I placed a ladder on each side of both chimneys so I could just keep working once I started and sprayed both from the top to the bottom. The material went on easily and dried fairly quickly. Now when it rains the water runs off and when I run my pressure washer it takes much less time and effort to rinse off any new dust and dirt. April 27, 2016
Rated 5.0 out of 5.0 by Thompson's never disappoints! I got this to use on my driveway and front porch in place of another popular brand that I had always used in the past. (Not sure if I can name other brands). I was a little weary at first using a different brand than usual, but I should have known better since every time I have used Thompson's I have always been very happy and they never disappointed me. This went on super easy and covered the area's real well. The drying time was pretty normal, which was just a little over 24 hours before I felt safe enough to park back in the driveway. That time was mainly due to the humidity by my house i'm sure. 24 hours is pretty normal for this type of product and what I used it for. I am very happy so far with this as it looks great and doesn't seem to make my driveway as slippery as the other brand after applying, which is nice. I will have to wait a while before I say how well it waterproofs the area, but Thompson's has never let me down before. I don't think that will be a problem but will update later after I have had more time to know for sure. April 13, 2016
Rated 3.0 out of 5.0 by Not crazy about this product. Not sure I can recommend this product. I usually use the Thompson's Wood Sealer each year on my deck. I power washed my deck and let it dry for over 24 hours. I rolled the Multi-survace Waterproofer on. It rolled on easily. It's kind of milky and thicker than the wood sealer. It is still tacky after four days and I don't like the appearance of the wood compared to the regular Thompson's Wood Sealer. In fact I had to go over areas with the regular wood sealer. March 1, 2016
Rated 4.0 out of 5.0 by Good product but follow the directions exactly! I have used Thompson Water Seal for Wood Surfaces for over 20 years on my wood porches and wood railings with great results. I received this multi-use product to use and review for The Home Depot Seeds /Product review program for use on wood surfaces and concrete sidewalk. I have found this multi-purpose sealer to be working well on my porches. As directed, we pressure washed, as we always do prior to using any sealant product, and allowed the wood to completely dry for 3 days before applying the sealer. We used a sprayer to lightly apply a small area as a test area. The results were good. We then sprayed 2 light coats on the porches but waited 4 days between coats to ensure it was dry and to see how the sealant responded. I read several reviews about this product so I was cautious in using. It seems the product causes more issues with concrete or stone surfaces so be sure to follow the directions! I attached a photo of the test area on my front porch that we treated with the non-treated area next to it for comparison. The water pooled up on the treated area but ran and was absorbed on the untreated area. October 23, 2015
Rated 1.0 out of 5.0 by Awful product I bought this despite the negative reviews based on Thompson's reputation and the price compared to the other big name brands. Big mistake. I applied one thin coat as the directions said but 48 hours later you can see all the roller strokes on my driveway and porch and the surface is sticky. I will give Thompson's some credit though. When I called to complain they immediately said there is a satisfaction guarantee and will refund my money. September 8, 2015
Rated 4.0 out of 5.0 by Good Sealant For Shed Outside Panels Ordered this to Seal the Wood Panels for the exterior of a Shed Project I am building. Although I am really not picky when it comes to shipping or packaging I received the 5 Gallon can all banged up & dented. Now this in no way hinders what is inside but wanted to note it for others. The Wife has been getting the Sheathing OSB Panels done to seal against any possible rain storm here in Montana before we finish with the Wood Paneling on the exterior of the Shed. June 29, 2015
