Concrete Moisture and Vapor Barrier DK 700 by SureCrete DK 700 Moisture Barrier and Vapor Blocker is a 2 component solvent-based urethane primer, 97% solids, low VOC ( 40 g/L), class 1 vapor barrier that meets ASTME96-E93. This Vapor Barrier stops water vapor transmission, to less then oe pound per 1,000 sq. ft. and opens up the possibility of applying high performance resinous coatings, including all Dura-Kote Systems, to uncured or moisture-laden concrete that was never before possible. It can also be used under applications of VCT, linoleum, and carpeting. Moisture barrier penetrates without blistering into the concrete?s porous surface to generate mechanical interlock and superior bonding. Bond strength exceeds that of traditional epoxy primers. DK 700 offers these advantages when applied in advance of any Dura-Kote Coatings: ? Moisture barrier ? Increased adhesion ? Better mechanical properties (including flexural and tensile strength) ? Increased working time PACKAGING - 1 gallon kit Part A 3 qts. (2.85 L) - 1 qt. Part B (.95 L) MIXING RATIO 3:1 / 3-parts A to 1-part B Coverage: Varies due to porosity of substrate, approximately 320-400 ft. (28 m) per gallon (3.8 L) or 3-4 mils wet.
