- Limitations
Lexite Conductive Top Coat should not be exposed to steel-wheeled traffic or temperatures above 150°F (65°C). Lexite Conductive Top Coat should not be applied when ambient or substrate temperature is below 50°F (10°C).
- Estimating/Coverage
The recommended application rate is 64 sq. ft./gal. (1.56 sq. m/liter) which yields a dry film thickness of 25 mils (0.64 mm). Do not apply Lexite Conductive Top Coat at thickness less than 20 mil or at thicknesses greater than 30 mils. Lexite Conductive Top Coat is normally applied in one application.
- 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.
- Priming: All concrete to receive Lexite Conductive Top Coat must be primed first with Lexite Conductive Primer and allowed to dry for at least 8 hours before applying the top coat.
- Mixing: Thorough blending of all components is essential. Mixing ratio is 2 parts 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 material.
- Application: After the substrate has been primed and al lowed to dry, distribute the mixed Lexi te Conductive Top Coat on the substrate with the use of a Lexite Spreader Tool. This allows the material to be applied at the recommended application rate of 64 sq. ft./gal. (1.56 sq. m/liter). The spreading operation should then be followed by rolling with a short-nap or foam-rubber type 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 technique. Lexite Conductive Top Coat is normally applied in one heavy application. Double coating may reduce the conductivity of the surface.
- Working Time/Pot Life: All mixed Lexite Conductive Top Coat should be applied within 20 minutes after mixing.
- Cure Time: Lexite Conductive Top Coat becomes tack-free in approximately 8 hours. The coated surface can be exposed to light traffic 24 hours after final application. 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 Top Coat 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. If recoating becomes necessary it may be necessary to reprime the surface. Consult a Metalcrete representative for special instructions.
