RAL 5018 Turquoise Blue Paint

Use this quick decision path to reduce acceptance risk. RAL codes define the target color only, not the coating process.

• Acceptance reference: If your PO/drawing says "RAL 5018" and inspection will be against the RAL standard swatch, a standard RAL 5018 finish is appropriate. If acceptance will be against an existing coated part or an OEM production finish, request a custom match to the actual part or specify the OEM powder code.
• Finish differences: Powder vs. liquid, texture, and gloss can shift appearance. For high-visibility or adjacent panel work, choose a sample-based match. For small repairs or cross-material coordination where sheen/texture already differ, a standard RAL 5018 is typically sufficient.
• Area/criticality: Large-area repaints or formal inspection programs favor a custom/OEM match. Low-criticality touch-ups (chips, protection) usually accept standard RAL.
• Documentation: State the acceptance reference (RAL card vs. existing part), required gloss/texture, and lighting for inspection to avoid disputes.

RAL 5018 is the color target; primer choice depends on substrate and service environment.

• Carbon steel: Clean to bright metal, remove rust/contamination. Use a zinc-rich or epoxy primer for corrosion resistance; topcoat with a compatible RAL 5018 system.
• Galvanized steel: Degrease and lightly abrade/sweep. Use a wash/etch or galvanized bonding primer before the color coat.
• Aluminum: Degrease and abrade. Use an etch or chromate-free epoxy primer for adhesion, then apply the RAL 5018 topcoat.
• Plastics: Confirm plastic type. Clean, scuff, and apply a plastic adhesion promoter or plastic primer compatible with the substrate, then topcoat.
• Previously coated surfaces: Clean and scuff-sand. If the existing coating is unknown, use a universal bonding primer and spot-prime any bare metal. Check a small area for lifting before full application.

Always verify primer-topcoat compatibility in product TDS and perform a small test panel when in doubt.

Lighting changes can make blue-green colors like RAL 5018 shift in hue (metamerism), and finish differences (gloss/texture; powder vs. liquid) amplify the effect.

• Control the light: Specify neutral, high-CRI inspection lighting (e.g., 5000-6500 K, high CRI) for color checks.
• Control the finish: State required gloss level and texture. Comparing a glossy spray-out to a textured powder part can appear different even at the same color target.
• Control the reference: Define whether acceptance is versus the RAL standard or an existing part. Use the same viewing angle and distance for all checks.
• Mitigate risk: Request a spray-out or drawdown of RAL 5018 and compare it next to your control part under the specified lighting. If differences remain unacceptable, order a sample-based match to the actual part.

• Temporary/urgent work: For small chips, functional corrosion control, or non-critical areas, a standard RAL 5018 touch-up or spray is typically acceptable. Expect some sheen/texture variance, especially next to powder-coated parts.
• Permanent/high-visibility work: For large areas, adjacent panel blending, or strict inspections, use a sample-based or OEM code match to the existing finish. Specify gloss, texture, coating chemistry, and inspection lighting to lock down acceptance.
• Mixed materials: If surfaces already differ (e.g., metal panel vs. plastic trim), standard RAL 5018 often achieves acceptable coordination without custom matching.
• Bottom line: Standard RAL 5018 solves speed and protection; a custom/OEM match reduces appearance risk where finish uniformity matters.

Yes, our spray paint, paint pens and touch up bottles are ideal for touching up parts of all kinds, including powder coatings. However, keep in mind that our version of RAL5018 Turquoise Blue is based on the color swatch contained in the official RAL color book. The color and sheen of your specific production parts may be different. If you need a touch up application, we can create a touch up solution precisely matching your specific parts.

While we can provide RAL5018 Turquoise Blue in paint, we don't provide any crossover information. We've found that every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another brand.

However, under the color image on a color page there is a link that says "Explore Colors". Clicking this link displays colors with similar values and you can look for any colors from the brand you want.

Keep in mind that this just shows similar colors based on the color values we have stored in our database. It doesn't mean it is the same or give any approximation about how close the color is. You can play around with the Hue, Lightness and Chroma sliders to expand the selection.
