How do I prepare and mix the LiME LiNE black basecoat?

Proper preparation ensures even color and sprayability. Begin with a clean, sanded substrate and well-mixed basecoat. Mix 1:1 with an appropriate urethane reducer as directed for your temperature and application method.

• Stir the quart thoroughly to reincorporate settled pigments.
• Mix one part basecoat to one part urethane reducer by volume.
• Strain through a 200–400 mesh filter into your spray cup to remove contaminants.
• Adjust reducer choice for ambient temperature and gun setup per technical data.

What spray equipment and settings work best with this 1K basecoat?

The product sprays well through most HVLP and conventional guns when reduced correctly. Use a 1.3–1.4 mm fluid tip for conventional setups, or 1.2–1.3 mm for HVLP, and apply thin, even coats to build color without runs.

• Typical fluid tip: 1.2–1.4 mm depending on gun type.
• Air pressure: follow gun manufacturer recommendations for even atomization.
• Flash time: short flashes between coats until full coverage is achieved.
• Finish with a compatible urethane clearcoat after proper dry time.

How durable and compatible is this basecoat with other refinish products?

As a single-component urethane basecoat, it’s formulated to be compatible with standard automotive clears and primers when system directions are followed. Durability depends on topcoat selection and proper cure; this product serves as the color layer within a multi-coat refinishing system.

• Designed to accept most 2K urethane clearcoats for top protection.
• Use over properly prepared primers or OEM surfaces according to industry practice.
• Avoid direct exposure without a clearcoat for optimal longevity.
• Test compatibility in a small area when mixing systems from different brands.

How much area will a quart cover and how many coats are needed?

Coverage depends on application technique and film build. Typically, a quart will cover a small panel or multiple spot repairs with 2–4 light coats to achieve even opacity for black shades.

• Estimate: enough for one or two panels with proper wet coats.
• Apply multiple thin layers rather than a single heavy coat to prevent runs.
• Allow appropriate flash time between coats for best flow and leveling.
• Finish with a compatible clearcoat after basecoat has flashed sufficiently.
