GBRadonSeal's eflorescence is tops Their eflorescence cleaner has little or no odor. It works effectively at neutralizing calcium bleeding through concrete block. I tried strong vinegar, it was ineffectual. Years ago I tried muriatic acid which worked about the same as RadonSeals product- but the smell was horrible. I ran short on this job, so I ordered another gallon- it works !

GBI love the product except I ran short… I love the product except I ran short of the urethane to repair my 6 ft crack with a single order of your product.

PRNot bad considering that: Not bad considering that: (a) The sales department did not know that Puerto Rico is a US possesion and we use the US dollar as currency. (b) The first invoice did not include UPS shipping (c) After paying the shipping charges invoice, I was informed that it was "cheaper" using the US postal service and was invoiced for "the difference" (d) Never got a tracking number regardless of the many times I asked for it to make sure that someone would be home. (e) It was shipped UPS Ground instead of US Postal Service s charged and the product was almost stolen. My wife arrived just in time when the driver of a pickup truck was on his way to my driveway to steal the 4 pails. He turned tails and ran away. Other than that. Peachy.

GB2 attempts, but basement is dry! My crack was difficult as it was the entire wall and it was behind the septic pipe. I was barely able to get it to work behind the pipe. The crack sealer did work, however, I did have to address one part of it 2 times. Preparing the area to accept foam again was not fun. I drilled behind the port this time and slowly injected foam untill the hydraulic pressure of the foam started to break the port off. I would have given this product 5 stars had it worked the first time. I am glad I bought the PRO kit as I used about 2.5 tubes of foam on the repair. I am still happy, it did work!!! We had over 1.5 inches one storm in an already wet week and nothing came in! Basement is dry!!!
