CONCRETE PHYSICS ARE UNCHANGED KEIM FINISHES ARE EXTREMELY VAPOR PERMEABLE CONCRETE BREATHES NATURALLY
Keim Concretal finishes will never blister or peel from trapped moisture. And, Concretal Paints are water repellent, keeping wind driven rain out of the concrete. The natural hydrophobic shedding action and resistance to dirt pickup, means your facades will stay cleaner looking.
Microporous mineral finishes are far more vapor permeable than concrete, meaning the concrete will stay drier. Internal moisture vapor freely escapes through the mineral finish without harm. And as mineral finishes cure, they take-on the physical properties of the surface including expansion coefficient and tensile strength.
