Applications

Work that suits a 2-pack finish

Components where the coating is part of the design — not just protection — and the colour has to match a brief, a brand or an adjoining surface.

Sign Trays & Panel Faces

Aluminium and ACM sign panels sprayed to a specified colour and gloss level before graphics or lettering are applied, so the background finish is even across the whole face.

3D Letters & Logos

Cut and fabricated letters in acrylic, metal or MDF coated on faces and returns. The paint system is chosen to suit the substrate and whether the letters live indoors or outside.

Architectural Panels & Reveals

Feature panels, trims, reveals and fit-out components finished to an architect-specified colour, where a brushed-on or aerosol finish would never pass inspection.

Joinery & Shopfitting Components

Routed MDF and plywood parts sealed, primed and topcoated for retail interiors, counters and display joinery, with the sheen level agreed before spraying starts.

Display & Exhibition Pieces

Plinths, props, sculptural forms and exhibition builds where the coating has to look consistent from every angle and survive handling, transport and repeated use.

Frames, Brackets & Fabricated Parts

Welded frames, brackets and fabricated steel or aluminium components etch-primed and topcoated so the finished assembly arrives ready for the next trade.

2-Pack Spray Painting

Why 2-pack beats ordinary paint

A 2-pack — or 2K — coating is mixed from two components: a pigmented resin and a hardener. Once combined, the film cures chemically rather than simply drying, which produces a harder, denser surface than any aerosol or single-pack paint can reach. The result holds its gloss, resists UV, cleaning chemicals and everyday abrasion, and keeps looking specified rather than touched up.

The finish is only as good as what sits underneath it, so preparation carries most of the effort. Board edges are sealed, surfaces are filled and sanded, bare metals get an etch primer, and high-build primer creates a flat base before any colour is sprayed. Application happens in a dust-controlled booth, which is the difference between a smooth architectural surface and a film full of nibs.

Because the paint shop sits beside our cutting floor, parts cut on the fiber laser, CO₂ laser and CNC router can be quoted as finished components — cut, prepared, coated and packed by one workshop instead of travelling between suppliers.

Chemically cured film

Harder and more even than air-drying paints, with stable colour and gloss in service

Preparation matched to the substrate

Sealing, filling, sanding and priming chosen for the actual material, not a generic routine

Booth-applied finish

Dust-controlled spraying keeps the surface consistent across faces, edges and returns

Sanding a primed panel before the topcoat is applied

Finishing Capabilities

Materials we finish

Most flat substrates from our cutting services can be primed and coated. Each material carries its own preparation route, confirmed at quote stage.

Metals

AluminiumEtch primed

Sign trays, panels, letters and fabricated parts. Etch priming gives the topcoat a proper key on the bare metal.

Steel & mild steelPrimed & sealed

Frames, brackets and fabricated components coated after welding and edge dressing, so the finish covers the completed part.

Stainless steelAdhesion prep required

Sprayed only after the surface is abraded and primed for adhesion. Tell us if any faces stay as raw stainless.

Plastics & composites

AcrylicCleaned & keyed

Cut letters and display parts painted on selected faces, or fully coated where the acrylic is simply the substrate.

ACM (aluminium composite)Light sand & prime

Composite panel faces sprayed to a specified colour where the stock coil colours don't match the project palette.

Foam PVCJob dependent

Selected display work only — the surface and intended use are reviewed before we commit to a finish level.

Boards

MDF & HMR MDFSealed & high-build primed

Routed letters, panels and joinery parts. Edges drink coating, so they are sealed and primed before any colour goes on.

PlywoodSealed first

Display and fit-out components sealed before priming so the grain doesn't telegraph through the finished surface.

Coating systems

  • Two-part polyurethane primer and topcoat systems
  • Gloss, satin, matte and textured finish levels
  • Colours matched to Pantone, RAL, Dulux or a supplied sample

Substrate preparation

  • Filling and surface repair before priming
  • Sanding and high-build priming for board edges and faces
  • Etch primers for bare aluminium and steel

Finish quality

  • Booth application in a dust-controlled environment
  • Smooth, even topcoat without orange peel
  • Consistent gloss and colour across a batch

Size & volume

  • Large-format panels through to small components
  • Single parts through to full production batches
  • Repeat colours recorded for later runs

These notes describe our standard finishing range, not a promise that every grade and surface will coat identically. Unusual plastics, laminated faces and customer-supplied parts may need review or sample testing before we commit to a finish level.

Why 2-Pack

Why choose a 2-pack finish?

What the process delivers that off-the-shelf paint cannot — and why finishing in the same workshop that cuts the parts matters.

Architectural-grade finish

A booth-sprayed 2K surface suits high-end signage, interiors, joinery and feature panels where the coating itself is on show.

Durable and UV-stable

The chemically cured film resists sunlight, weather, cleaning chemicals and everyday knocks far better than single-pack paint.

Colour matched to specification

Corporate colours, Pantone and RAL references, Dulux colours or a physical chip can all be matched before production.

Smooth, consistent surface

Controlled booth conditions keep dust out of the wet film, so faces, edges and returns all read as one finish.

Cut and finished under one roof

Parts cut on our lasers, CNC router and knife cutter move straight into the paint shop — one file, one supplier, one finished part.

The Process

How a part moves through the paint shop

Five stages, in order. Preparation and cure take most of the time — spraying the colour is the short part.

1

Review the parts and spec

We confirm the substrate, colour reference, finish level and which faces matter before anything is sanded or sprayed.

2

Prepare the substrate

Filling, sanding and sealing as the material requires — board edges are sealed, metals are degreased and abraded.

3

Prime

Etch primer on bare metals, high-build primer on boards and repaired surfaces, then a guide sand to a flat base.

4

Apply the topcoat

The matched 2K colour is sprayed in the booth at the agreed gloss level, with wet-film checks between coats.

5

Cure, check and dispatch

Parts cure fully before handling, are inspected against the colour reference, then packed for collection or delivery.

Quote preparation

What makes a finishing quote accurate?

Tell us the substrate, part sizes, quantity, the colour reference — Pantone, RAL, Dulux or a physical sample — and the finish level: gloss, satin, matte or textured. Say whether the work lives indoors or outside, and which faces and edges are visible in the finished job.

If we are cutting the parts as well, send the cut file with the enquiry and the whole job — cutting, preparation, coating and packing — is quoted as one piece of work through fiber laser cutting, CO₂ laser cutting or CNC routing.

Next Step

Send the parts, the colour and the finish level.

Include the substrate, sizes, quantity, colour reference and whether the work is for indoor or outdoor use. If we are cutting the parts too, attach the cut file and the job is quoted end to end.
