RAL 7031 Blue Grey Paint

RAL 7031 Blue Grey defines a color target, not the coating process. Decide based on how the work will be inspected.

• Use standard RAL 7031 Blue Grey when: cross-material coordination is acceptable (powder vs. liquid, different textures/sheens), you are doing low-criticality touch-up or small chips, or close visual harmony is sufficient without sidebyside scrutiny.
• Request a sample/OEM match when: the surface is high-visibility or large-area, there are strict acceptance/inspection requirements, a known OEM powder code exists, or acceptance is defined as "match this existing coated part."

Risk note: Powder vs. liquid, sheen, and texture can make the same RAL color appear different, especially under varied lighting. If inspection is sidebyside or under controlled lighting, a sample/OEM match reduces rejection risk.

Ordering tip: State the acceptance basis on your PO-either "Target: RAL 7031 Blue Grey (RAL Classic standard)" or "Target: match customer sample/OEM powder code [specify]."

RAL 7031 Blue Grey defines color only; appearance acceptance often hinges on sheen and texture.

• Match what exists: If possible, measure the installed coating with a 60 degrees gloss meter and specify the target in gloss units (e.g., 35 GU ±5). If you cannot measure, compare to a gloss reference set in the field.
• Typical ranges (for quick orientation): flat/matte <10 GU, satin 20-35 GU, semigloss 40-60 GU, gloss >=70 GU. Powder-coated parts are commonly satin to semigloss, but verify-do not assume.
• State acceptance conditions: viewing distance, service lighting (e.g., 4000K LED shop lights vs. daylight), and whether judgment is visual or instrumented. Lighting can make RAL 7031 appear lighter/darker; evaluate under the actual service lighting.
• When uncertainty is low-risk (small touch-ups): consider ordering small quantities in two adjacent sheens for on-site trial, then document the winning sheen for production.

• Verify compatibility: Identify substrate and existing coating. Do a small solvent/rub test in an inconspicuous spot to confirm the existing finish will tolerate touch-up.
• Clean: Wash with detergent, rinse, dry. Wipe with isopropyl alcohol or a suitable solvent to remove oils/silicones. Do not use household cleaners that leave residue.
• Repair/feather: Remove corrosion to clean metal; lightly feather chip edges. Fill if needed and sand smooth.
• Scuff: Lightly abrade the repair area (e.g., 320-600 grit) to degloss and promote adhesion. Vacuum and tack-wipe.
• Prime where required: Spot-prime bare metal or plastics with an appropriate primer for the substrate and intended topcoat chemistry. Allow proper dry time.
• Mask and test: Mask adjacent areas. Apply a small test area first. Evaluate color and adhesion after the film flashes/cures and under the actual service lighting.

Note: Texture and gloss will affect the perceived color of RAL 7031 Blue Grey. Final color judgment should be made after full cure in the lighting where the part will be used.

• Color target: "RAL 7031 Blue Grey." State the match basis: "RAL Classic standard" or "Match to customer sample/OEM powder code [list code]."
• Finish: Sheen (60 degrees gloss target and tolerance) and any texture requirement.
• Coating details: Product type/form (e.g., liquid, aerosol), intended coating chemistry class (e.g., acrylic, epoxy, polyurethane) for compatibility, and application method.
• Substrate and service: Substrate type and any environmental/service constraints that influence primer/topcoat choice.
• Acceptance: Inspection method (visual/instrument), lighting conditions, viewing distance, and whether comparison is to the RAL standard or a supplied part.
• Controls: Required wet/dry film thickness, cure time/temperature if applicable, lot/batch traceability, and whether a retain panel is required for future reference.

Including these items minimizes disputes and makes future reorders of RAL 7031 Blue Grey consistent with the accepted standard.

While we can provide RAL7031 Blue 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.
