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 !

GBEasy apply, excellent support Sealing cracks I thought was going to be a horrible task, but Radon seal made it easy! With excellent directions and video help, the process was simple and it worked perfectly. I am super happy I found this product and the purchase was simple, and applications was a piece of cake.

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.
