Rated 1.8 out of 5 by 39 reviewers.
Rated 1.0 out of 5.0 by Doesn't dry clear, never dries, don't risk it I just ruined a brand new $5000 concrete porch with this shoddy stuff. It doesn't dry and it leaves brush and roller marks. It is sticky after 2 weeks in the sun. First, the email address at their website kicks back all emails. Next, the phone line puts you on hold, then hangs up on you. When I got through, they wouldn't stand behind it. This was not a defective can, this is what it does, read the reviews online. September 9, 2014
Rated 4.0 out of 5.0 by Works Well if Used Correctly I saw some bad reviews for this product so I decided to test it on a piece of 2x4 that I had first. Also it is too cold here right now to treat anything outside. I applied the waterproofer according to the directions and let it dry for 24 hours. After 24 hours it was completely dry and when I dropped water on it the water beaded up nicely, check photo. The directions do say that “Tackiness will result if over applied”, so I can only believe that others have put too much on. I have used the old stuff and that is as thin as water so you can put on as much as you like. It is a little different because it looks like milk when it goes on too. The other thing that might make it tacky is if you treated an area that didn’t need it. If the water already beaded up on it. I have that problem with my deck because right behind the house where it is sheltered from the rain and sun it really doesn’t need treating. I look forward to the weather getting warmer so I can get some things done with this. This is expensive because it is 5 gallons but per gallon it works out fairly cheap. So if you have a lot to do it is good March 26, 2015
Rated 5.0 out of 5.0 by Thompson's Clear Waterproofer I love Thompson Waterproof Sealant as it never fails me. I used this on my wheelchair ramp and planned to use it on my porch also but then decided since the paint job that had been done prior to my acquiring the home had begun to chip and flake off that I would go ahead and repaint the entire porch and ramp areas then finalize all of it with the Thompson Clear Waterproof Sealant.

Rated 3.0 out of 5.0 by Not as bad as descirbed When I saw the other reviews from as long as two years ago, I was shocked to see the negative ones, almost all of the total. I wondered what went wrong so I immediately did a simple test. The test was good and dried in the 48 hours stated in the instructions. Admittedly it did feel very slightly tacky compared to a section that was bare. So I walked all over it with ordinary sneakers. I felt no stickiness that way and the surface remained unmarked or disturbed in any way. The material had a milky appearance right out of the can and did have many air bubbles, which did not affect the application with a brush. I don't know how the bubbles might affect a sprayer. The recommendation is to use a garden sprayer, so maybe that would be more appropriate than a powered one. The results after 4 hours time were satisfactory with water beading up on the part that was sealed and water soaking in on the part that was not sealed. The label on the can did not advertise the material was "low VOC" but there was a claim in fine print that it was less than 120 g/L VOC. Technically, that is low VOC and is much lower than the government requires (250 g/L). This does affect the drying time and the need to keep the coats as thin as possible. The instructions do say it is required to use a wood cleaner before application, but I did not do that. I did not find the material to be thicker at the bottom of the can even though it was not shaken or stirred before checking. Maybe the formula has changed lately. I noticed that all the negative reviews were from non-Seeds members and wanted to make sure this was a fair evaluation. That many folks can't all be wrong. So I hesitated a bit before checking the Yes button to recommendation the product. Still I rated it only 3 stars because of the limitations the new product entails. I was intending to use this material on a large outdoor desk, but now I am very hesitant; perhaps after more testing. April 23, 2015
Rated 1.0 out of 5.0 by Horrible horrible horrible product! Applied as directed on on a brick porch. 2 days now and it is still sticky / tacky and the sticky product gets all over anything it touches like the bottom of your shoes. I agree with the other 22 out of 23 posters that this is the worst product we have ever used. Now we have to figure out how to get this sticky goop off of our brick. What a nightmare and what a waste of our time. I will be returning this product for a full refund. I can't believe Home Depot or anyone else even sell the super bad product. September 3, 2014
Rated 1.0 out of 5.0 by bad the most useless item being sold today. a complete waste of money time effort, now I have to find another product to cover up the mess. save yourself the headache March 29, 2015
Rated 5.0 out of 5.0 by Saves tons of Maintenance !!!! I have been using Thompsons for at least ten years. I use the multi surface waterproofer for everything that goes outdoors from wood to cement and have used it on some patio cushions. (you have to check a small area an make sure it wont discolor fabrics first).... Every fall I coat the sidewalks around my work building, It helps shed the water as well as it seems to help keep the salt from destroying the cement. Its a good price for the future maintenance it will save you.... May 1, 2015
Rated 1.0 out of 5.0 by Use something else for your pressure treated deck I can't tell you what is best to use, but after treating my 500 square foot deck with this product, I can certainly tell you this is NOT the stuff you want to use. I concur with most of the other reviewers... this product is VERY POOR. The old clear formula was great, but this new milky colored stuff is garbage. The catch is that they did not change anything at all on the can. I thought I was buying the old formula. Nope, it's the new milky stuff and now my deck looks like a 7 year old did the work. Next year I will know better and will use a different brand. October 26, 2014
