Surface preparation

Sanding scratches not visible under raking light before coatingCRITICALDust and sanding residue removed before each coatGlue squeeze-out cleaned from joints and cornersCRITICALWood fillers match grain and colour after finishingEdges and corners softened consistently to the drawingMoisture content of wood within specified range before finishingCRITICALRaised grain controlled after stain or water-based first coat

Coating defects

No runs, sags or curtains on vertical surfacesCRITICALNo orange peel beyond the approved master sampleNo fisheyes, craters or silicone contaminationCRITICALNo bubbles, pinholes or blistersNo dry spray, overspray rough or dust nibs in visible areasCoating film thickness within specification where measuredNo blushing or cloudiness in clear coatSheen level matches the approved master

Colour and appearance

Colour matches master sample under the agreed light sourceCRITICALShade variation between parts of one product is within toleranceCRITICALGrain direction and pattern consistent across visible panelsNo blotching on stained species prone to itTouch-up areas blend and are not visible at normal viewing distance

Coating performance

Cross-hatch adhesion test passed on sample from the lotCRITICALSurface fully cured, no tackiness or finger marksScratch and mar resistance per customer requirementHot, cold or chemical resistance tested where specifiedNo odour beyond the approved level after curing

Assembly, hardware and packing

Hardware fitted, tight and free of finish contaminationCRITICALDrawers and doors operate smoothly with even gapsNo exposed sharp edges, splinters or protruding fastenersCRITICALProtective felt, glides and corner guards fittedItem labels, product code and compliance markings correctCRITICALPackaging protects finished surfaces with no direct contact marksCarton marking and quantity match the packing list

Every critical item must pass for the lot to be released. Record non-critical failures as defects and compare with your agreed acceptance quality limit.

Defect trend reporting

Optional: how to turn inspection results into defect trends by line, shift and product.

Optional. The tool and every export work without this. No spam.

How to use the checklist

Inspect under consistent lighting, ideally a standard daylight booth or raking light for surface defects. Hold the approved master sample beside the piece. Work through each group, tick items that pass and note part numbers and positions for any failures. Export the completed list to PDF for the lot record or to attach to a customer shipment.

Inspect at normal viewing distance first, then closely for suspected defects.
Photograph every failure with a scale reference.
Record lot, shift and finishing line for traceability.

Understanding common defects

Orange peel is a textured, dimpled surface from poor atomisation or incorrect viscosity. Fisheyes and craters usually come from silicone or oil contamination. Runs and sags come from excess film build. Blushing is a milky haze, often from humidity during drying. Knowing the cause helps the finishing supervisor correct process settings rather than just reworking pieces.

Setting acceptance criteria

Agree visible-area definitions with the customer: top surfaces and fronts are strictest, hidden undersides are looser. Many buyers use an AQL sampling plan for appearance defects and zero tolerance for safety items such as sharp edges. Document both in the quality agreement so the checklist reflects real contract terms.

Closing the loop

Log defect types by finishing line and booth. A recurring pattern, such as dust nibs on one shift, points to a process cause. Link rework and scrap back to the work order so cost of poor quality is visible per product.

Frequently Asked Questions

What are the most common furniture finishing defects?

Orange peel, runs and sags, dust nibs, fisheyes, blushing, blotchy stain, colour mismatch and poor adhesion. Most trace back to surface prep, contamination, spray settings or booth conditions.

How do I check coating adhesion?

A cross-hatch test cuts a grid into the cured film, applies standard tape and compares the removed area with a rating chart. Follow the method named in your customer specification.

What viewing distance applies?

Many buyers specify a distance and lighting for appearance inspection, such as about one metre under good light. Use what your quality agreement states and keep it consistent between inspectors.

Can I add my own items?

Yes. Treat this as a base list and add product-specific checks, for example UV coatings, outdoor finishes or customer labelling rules, before exporting for your records.

Netray can help capture inspection results against work orders in your ERP and trend defect types by line, shift and product, without replacing your quality system.
