- Limitations
Lexite Conductive Primer should not be exposed to steel-wheeled traffic or temperatures above 150°F (65°C). Lexite Conductive Primer should not be applied when ambient or substrate temperature is below 50°F (10°C).
- Estimating/Coverage
The recommended application rate is 250 sq. ft./gal. (6.1 sq. m/liter) which yields a wet film thickness of 7 mils (0.18 mm) and a dry film thickness of 3 mils (0.08 mm). Lexite Conductive Primer may be installed in two applications where additional protection is required.
- Directions for Use
- Preparation: The surface to be treated must be physically sound, thoroughly clean, free of oil, wax, loose paint, rust, scale, and completely dry. New concrete must be thoroughly cured for at least 28 days before starting surface preparation. Base concrete must be shotblasted or acid-etched with Bitesin. All acid-etched concrete surfaces must be rinsed and neutralized with potable water and allowed to completely dry.
- Mixing: Thorough blending of all components is essential. the mixing ratio is 1 part binder to 1 part activator by volume. Use a power drill with a Metco Jiffy mixing paddle. First, mix the binder separately; then, mix the activator separately. Next, add the mixed activator to the mixed binder and thoroughly blend for at least two minutes at revolution speeds that will not entrap air bubbles into the freshly mixed material.
- Application: Distribute the mixed Lexi te Conductive Primer on the substrate with a short nap paint roller to insure uniformity. The rolling operation should proceed in one direction with slow, even strokes. Avoid short, quick, back-and-forth strokes such as are commonly employed in paint rolling techniques. Lexite Conductive Primer may also be applied with an airless industrial sprayer.
- Working Time/Pot Life: All mixed Lexite Conductive Primer should be applied within three hours after mixing at 70°F (21°C).
- Cure Time: Lexite Conductive Primer becomes tack-free in approximately 8 hours and may be top coated with Lexite Conductive Top Coat at this time. The Lexite Conductive Primer surface can be exposed to light traffic 24 hours after application of the coating, however prompt top coating is recommended. Final cure time requires 3 to 7 days. All cure times are based on ambient and substrate temperatures at 70°F (21°C).
- Clean-up: Ei ther DL Solvent or Waterzal l Concentrate and warm water may be used for cleaning tools and equipment.
- Maintenance: Lexite Conductive Primer surfaces should be cleaned with a Waterzall Concentrate and water solution. Waterzall Concentrate may also be used at full strength to remove built-up deposits and stains. Lexite Conductive Primer may be reapplied to itself.
