Primer build and progressive sanding
After initial preparation, suitable sealers and primers are used to stabilise the surface and create enough build for accurate levelling. Between coats the surface can be sanded again so that edges, repaired areas and broad faces become progressively more uniform. Where the substrate remains absorbent, uneven or technically demanding, additional primer cycles may be required.
For specialist work the coating build may include high-build or polyester-based primer systems where they are appropriate to the substrate and the intended finishing system. The purpose is not simply to make the coating thicker: it is to create a stable, level foundation that can be refined without losing edge definition or introducing unnecessary distortion.
Colour depth and clear lacquer
Colour is applied only when the base is ready. The number and type of colour coats depend on coverage, shade, coating system and the visual target. Deep colours and highly reflective finishes are particularly unforgiving, so consistency of film build, curing and cleanliness matters throughout the process.
Where the specification calls for it, a compatible clear lacquer can be built over the colour to provide additional depth and a surface that can be refined after curing. Not every job needs a separate clear coat; the correct system depends on the material, colour, use and required appearance.
Flattening, compound polishing and final refinement
Once the coating has cured sufficiently, the finish can be carefully flattened with fine, progressively controlled abrasives. This stage corrects suitable texture and small surface imperfections while preserving edges and geometry. Machine compounding and finer polishing stages then develop clarity, depth and reflection.
Polishing may be repeated with progressively finer compounds and pads until the required gloss level is reached. The final surface is inspected under directional light and from different angles for haze, sanding traces, local distortion, contamination and consistency of reflection.
