This class covers painting, varnishing, polishing, decorating, protective coatings, and finishes applied to any surface (new or old, internal or external).
1. Scope
Class V includes:
- Painting on all surfaces (wood, metal, plaster, concrete, masonry, etc.).
- Varnishing, polishing, oiling, waxing of timber.
- Protective coatings – bituminous, anti-corrosive, epoxy, polyurethane, enamel.
- Decorative coatings – textured paints, distemper, emulsion, plastic paints.
- Priming coats, undercoats, finishing coats.
- Special coatings – fire-retardant, anti-fungal, weatherproof paints.
- Surface preparation – cleaning, sandpapering, filling cracks, knotting, rubbing down.
- Markings – painting of lines, lettering, and numbers (roads, pavements, steelwork).
2. Subdivision of Items
Painting and finishing are divided according to:
- Type of surface
- Woodwork.
- Metalwork.
- Plastered/brick/concrete surfaces.
- Road or floor surfaces.
- Type of coating/finish
- Whitewash, color wash, cement wash.
- Oil paint (gloss, matt).
- Enamel paint.
- Acrylic or plastic emulsion.
- Textured/decorative finishes.
- Bituminous, epoxy, polyurethane paints.
- Fire-retardant/anti-corrosive coatings.
- Varnish, French polish, wax polish.
- Number of coats
- Single coat, two-coat, three-coat systems.
- Primer + undercoat + finishing coat.
- Location
- Internal walls.
- External walls.
- Ceilings.
- Joinery, doors, windows.
- Steel structures.
- Floor or road markings.
3. Method of Measurement
- Painting of surfaces (wood, metal, plaster, masonry, concrete) – measured in square metres (m²).
- Painting of pipes/railings – measured per linear metre (m) based on diameter (for pipes) or overall area developed.
- Painting of lettering, numbering, or markings – measured per number (No.) or per m² for continuous markings.
- Polishing or varnishing of timber – measured in m².
Deductions:
- Openings exceeding 0.5 m² are deducted.
- No deductions for small openings less than 0.5 m².
4. Item Coverage
Each item includes:
- Surface preparation (cleaning, knotting, priming, filling, sandpapering).
- Supply of all materials, scaffolding, staging.
- Application of primer, undercoat, finishing coats.
- Protection of adjacent works.
- Curing/drying of coatings.
- Removal of splashes and cleaning on completion.
5. Notes for BOQ Preparation
- Specify surface type (wood, metal, plaster, etc.).
- Mention paint/finish type (oil-based, emulsion, epoxy, polyurethane, etc.).
- State number of coats (primer, undercoat, finish).
- Clarify if scaffolding is included/excluded.
- For steel structures, specify corrosion protection system (zinc primer, epoxy coat, PU finish).
- For road markings, specify paint type and thickness (hot thermoplastic, reflective paint).
- For timber, specify finish (varnish, polish, wax, oil).
6. Example BOQ Items
- V.1.1: Two coats of whitewash on new plastered surface, measured per m².
- V.1.2: Three-coat plastic emulsion painting (primer + two coats) on interior walls, measured per m².
- V.2.1: Enamel painting (two coats over primer) on steel windows, measured per m².
- V.2.2: Painting 100 mm dia GI pipes with two coats of anti-corrosive paint, measured per linear metre.
- V.3.1: French polishing on teakwood doors, measured per m².
- V.3.2: Varnishing two coats on hardwood handrails, measured per m².
- V.4.1: Epoxy painting (DFT 200 microns) on structural steel, measured per m².
- V.4.2: Thermoplastic reflective road marking paint, 2.5 mm thick, 100 mm wide, measured per linear metre.
- V.5.1: Painting of letters/numbers with synthetic enamel paint, 100 mm height, measured per number.
✅ In summary:
Class V covers all painting, polishing, varnishing, decorative, and protective coatings. Measurement is generally in m², except pipes (m), markings (No. or m²), and special finishes. BOQ items must specify surface, paint type, coats, and finish.
