Right Prime does not require additional mixing or diluting before use. It can be applied on vertical or horizontal surfaces by rolling or brushing the surface after the area has been prepped for installation of our Right Roll Self-Adhering Waterproofing Membrane & Pave Patch-Gray Hot Applied Mastic. Suitable preparation includes clearing the area of unstable pavement, rocks and dust, and then drying completely. After applying, allow Right Prime to dry for one hour or until the entire surface maintains a tacky feeling. Concrete surfaces should be cured at least 72 hours before applying Right Prime. Along with being used as an adhesive, Right Prime can also dustproof any clean and smooth surface free of contaminants.
