Description DEHYDRATINE 75 is a VOC compliant, water based compound designed to dampproof concrete and masonry. The DEHYDRATINE formulation is derived from mineral colloid asphalt base clay emulsions which utilize a water carrier. It can be used above and below grade. DEHYDRATINE 75 is highly effective and is easily applied by trowel or spray.
