Pour Aqua prime (R} and add Aqua prime [H] and mix both components thoroughly for 3 min using a low-speed drill (300 – 400 rpm) to minimize entrapping air. Always mix complete packs, never split packs. Visually ensure that the mixture has become homogeneous. Only start the application of Aqua Prime after the priming coat has dried tack-free. Otherwise, there is a risk of wrinkling or impairing the conductive properties. Apply the conductive primer to the prepared substrate, which should be pore-free and pinhole-free. Aquaprime must be applied with a 3/8″ nap roller and roller trays. 18-inch (46 cm) roller assemblies and trays are preferred. The roller should be wet in the tray, and then the excess coating is removed by lightly rolling in the tray so as to avoid drips. Then apply 3 pairs of 6 – 8 foot (approx. 1.80 m – 2.40 m) long paths onto the floor. Then spread the material with roller passes perpendicular to the paths of coating. It is extremely important to apply the coating at a rate of 4 – 6 mils (100 – 150 µm) to achieve proper appearance, texture, and color development, and consistent ESD properties. If areas are too thick, the coating may be too soft; if too thin, the coating will appear very flat in sheen and may exhibit poor electrical properties. Work evenly to avoid late “tie-in” and rerolling to adjacent previously applied material; Doing so may result in color variations.
