6 problems with concrete countertop mix designs and how to

Defoamers such as Fritz-Pak Air-Minus work by preventing stable air bubbles from forming during mixing. Defoamers don't make air disappear, rather they reduce the cement paste's surface tension characteristics so bubbles are harder to form. The concrete still needs to be fluid enough to allow the bubbles to escape.
