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.

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 !
