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.

GBProduct performance was very good, instructions lacking Product performance was very good. However, design function of the caulking style tube was not. A normal tube is empty when the charging rod is fully deployed inside the empty tube. Without knowing the charging rod is fully deployed at 3/4 of its normal length caused considerable delay and improper injection of the polyurethane foam into the concrete wall.

GBGood value for the price The product arrived quickly and worked as advertised. The only critique is that it would be nice if the application instructions described how much the caulking gun will travel before the tube is empty. Will recommend to others who have foundation crack issues.
