LiME LiNE Automotive 1K Urethane Black Basecoat Quart — 1:1 Mix, Spray-Ready Deep Black

LiME LiNE Automotive 1K Urethane Black Basecoat (quart) is a one-component urethane basecoat formulated to deliver deep black color and easy 1:1 mixing with urethane reducer for automotive refinishing.

This quart of LiME LiNE black basecoat is designed for collision repair shops, body shops, and skilled DIYers who need a reliable, single-component color system that sands and lays down evenly under clear coats. The product is supplied as a base color only (1k), so it requires a urethane reducer and a compatible clearcoat to complete a durable finish. It’s formulated for spray application and intended to be mixed 1:1 with urethane reducer for optimal flow and atomization.

How should I prepare and mix LiME LiNE black basecoat?

Preparation begins with a clean, dust-free substrate and proper surface sanding. Measure precisely and mix the quart with urethane reducer at the recommended 1:1 ratio to achieve the intended viscosity and spray pattern.

• Clean and degrease the panel before sanding.
• Mask and tack cloth to remove particles.
• Mix basecoat and urethane reducer 1:1 by volume, stir thoroughly.
• Strain the mixed material before pouring into the spray gun cup.

What spray settings and application technique work best?

Use a gravity-feed or siphon spray gun with a typical basecoat nozzle (approx. 1.2–1.4 mm) and adjust air pressure for smooth atomization. Apply multiple thin, even fog coats and allow appropriate flash time between passes to avoid runs.

• Nozzle size: 1.2–1.4 mm recommended.
• Air pressure: adjust to gun manufacturer guidance for basecoats.
• Apply 2–4 light coats with 5–10 minute flash between coats.
• Allow full flash before clearcoat according to temperature.

Can this basecoat be used with different reducers and clears?

Yes — it’s compatible with urethane reducers and most single- or two-stage urethane clears, provided you follow the reducer and clear manufacturer’s guidelines. Select reducer speed to match ambient temperature for consistent drying and leveling.

• Mix 1:1 with a urethane reducer chosen for current temperature.
• Use a compatible urethane clearcoat for final protection and gloss.
• Follow recommended dry times of the clearcoat manufacturer.
• Test in a small area if using unfamiliar products together.
