No more delaminations or hydrostatic pressure problems with Dyna-Prime Water Chasing Primer N-23. The penetrating primer 100% reactive waterproofing product achieves a vapor barrier and up to 5/8 inch penetration at an application thickness of only 6 mils. As a single-coat application, it builds a structure that is an integral part of the concrete rather than relying on simple adhesion to the concrete surface. It costs less than 20 cents/sq ft when purchased in bulk. Creative Material Technologies Ltd.
