RAL 7004 Signal Grey Paint

RAL 7004 Signal Grey is a color target, not a coating process. Choose the approach that aligns with your acceptance criteria.

• Use standard RAL 7004 when: (1) the spec or drawing only calls out "RAL 7004," (2) cross-material coordination is needed and textures/sheens already differ, (3) the work is low-criticality (small chips, functional touch-up), or (4) close visual harmony is sufficient. Expect minor differences in hue/appearance between powder and liquid, and across gloss levels/texture.
• Request a custom or OEM match when: (1) parts sit side-by-side with existing coated components, (2) the surface is high-visibility or large-area, (3) inspection is strict (formal pass/fail), or (4) you have a known OEM powder code or a physical sample to match. This reduces risk from powder vs liquid sheen/texture differences.

To control acceptance risk, specify: target (RAL standard vs your sample), gloss (e.g., 30±5 GU @60 degrees), texture/smoothness, inspection lighting, and color tolerance (e.g., visual match to approved control panel). Provide or request a retained control sample if critical.

Yes, with correct surface prep and product selection. The goal is to ensure adhesion and manage appearance differences.

• Assess the surface: Only coat intact, clean, and sound powder. If chalked or glossy, plan to degloss.
• Prep: Clean with detergent, rinse, dry. Scuff-sand to dull the surface (e.g., 320-400 grit on smooth powder). Feather any chips to solid edges. Remove corrosion and spot-prime bare metal.
• Primer: If substrate is exposed or the existing powder's chemistry is unknown, use a compatible adhesion-promoting or epoxy primer.
• Adhesion check: Do a small masked test area before full production. Verify adhesion and appearance after full cure.
• Appearance expectations: Liquid touch-up over textured powder may look different even when the color is RAL 7004. If a seamless cosmetic blend is required, supply a part for a custom match with the desired gloss/texture.

Coverage depends on product type, application, and substrate contrast. As a mid-gray, RAL 7004 typically hides efficiently.

• Typical theoretical range: ~300-400 sq ft/gal at 1 mil DFT (varies with solids). Plan practical coverage lower due to application losses and profile.
• Coats: Over similar gray primer, 1-2 coats often achieve hide. Over high-contrast surfaces (white/black) expect 2-3 coats or use a gray-tinted primer close to RAL 7004 to reduce coats.
• Aerosol reference: A 12 oz can yields roughly 10-15 sq ft per full coat; small chip repairs use far less.
• Verification: Confirm on a test panel with your equipment, film build target, and primer to lock in actual spread rate before production.

• Color target: RAL 7004 Signal Grey (RAL Classic). State if matching the standard or a submitted sample/OEM powder code.
• Finish parameters: Gloss level (e.g., 30±5 GU @60 degrees), texture/smoothness, and any special effects.
• Coating details: Product chemistry (e.g., epoxy, polyurethane), solventborne/waterborne, application method (spray, etc.), and cure schedule.
• System context: Substrate, pretreatment, primer, and target DFT for each layer.
• Inspection criteria: Visual match under specified light (e.g., D65), tolerance to target (define pass/fail), and whether a retained control panel is required.
• Traceability: Record lot/batch numbers and request a labeled retain or drawdown panel with shipment.

Avoid using photos as acceptance references; use the RAL standard or your approved control sample instead.

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 RAL7004 Signal Grey 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 RAL7004 Signal Grey 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.
