Paint and coating coverage rates for estimation and procurement. Actual coverage depends on surface porosity, texture, application method (brush/roller/spray), and number of coats.
Interior Paints (per litre, per coat)
Smooth plastered surface, brush/roller application
| Paint / Coating | Coverage | Coats | Surface | Note |
|---|
| Cement Primer | 8–10 m²/L | 1 coat | New plaster | Apply after 28 days curing |
| Acrylic Distemper | 8–10 m²/L | 2 coats | Interior walls | Economy option, not washable |
| Interior Emulsion (economy) | 10–12 m²/L | 2 coats | Interior walls | Washable |
| Interior Emulsion (premium) | 12–14 m²/L | 2 coats | Interior walls | Better hiding, smoother |
| Interior Emulsion (luxury/silk) | 10–12 m²/L | 2 coats | Interior walls | Sheen finish |
| PVA Primer | 8–10 m²/L | 1 coat | Interior plaster | Before emulsion |
Exterior Paints (per litre, per coat)

| Paint / Coating | Coverage | Coats | Surface | Note |
|---|
| Exterior Primer | 7–9 m²/L | 1 coat | Exterior plaster | Alkali resistant |
| Exterior Emulsion (standard) | 8–10 m²/L | 2 coats | Exterior walls | Acrylic based |
| Exterior Emulsion (premium) | 10–12 m²/L | 2 coats | Exterior walls | UV + rain resistant |
| Exterior Texture Finish | 1.5–3.0 m²/L | 1 coat | Exterior walls | Thick coating |
| Cement Paint (snowcem type) | 3.5–4.5 m²/kg | 2 coats | Exterior walls | Per kg of dry powder |
| Lime Wash / Whitewash | 4–5 m²/L | 3 coats | Any plastered wall | 1 kg lime per 5L water |
Wood & Metal Paints (per litre, per coat)
| Paint / Coating | Coverage | Coats | Surface | Note |
|---|
| Wood Primer (pink/white) | 10–12 m²/L | 1 coat | New wood | |
| Enamel Paint (synthetic) | 12–14 m²/L | 2 coats | Wood, metal | Glossy finish |
| Metal Primer (red oxide) | 8–10 m²/L | 1 coat | Steel, iron | Anti-corrosive |
| Metal Primer (zinc chromate) | 10–12 m²/L | 1 coat | Aluminium, galvanised | |
| Aluminium Paint | 12–14 m²/L | 2 coats | Metal, wood | Heat reflective |
| Varnish (clear/wood) | 12–15 m²/L | 2–3 coats | Wood | French polish: lower coverage |
| Bituminous Paint (black) | 6–8 m²/L | 2 coats | Metal, concrete | Anti-corrosive for pipes, tanks |
Putty & Base Coats (per kg)
| Paint / Coating | Coverage | Coats | Surface | Note |
|---|
| Wall Putty (cement-based) | 1.0–1.2 m²/kg | 2 coats (1mm each) | Interior walls | 50–70 kg per 100 m² for 2 coats |
| Acrylic Wall Putty | 1.2–1.5 m²/kg | 2 coats | Interior walls | Better spreadability |
| Plaster of Paris (POP) | 0.5–0.8 m²/kg | 1 coat | Ceiling, walls | 1–2mm thick |
| White Cement Base Coat | 1.0–1.5 m²/kg | 1 coat | Before putty | |
Waterproofing & Specialty
| Paint / Coating | Coverage | Coats | Surface | Note |
|---|
| Waterproofing Coating (elastomeric) | 1.0–1.5 m²/L | 2 coats | Terrace, walls | 2 coats = 1 L/m² |
| Epoxy Paint (floor) | 4–6 m²/L | 2 coats | Concrete floor | Self-leveling higher coverage |
| Anti-fungal Paint | 10–12 m²/L | 2 coats | Damp walls | |
| Heat Reflective Paint (cool roof) | 3–4 m²/L | 2 coats | Terrace/roof | Ceramic-based |
| Fire Retardant Paint | 3–5 m²/L | Per specification | Steel, wood | Intumescent type |
Notes
• Coverage rates are approximate — actual coverage depends on surface condition and application method
• Spray application uses 10–15% more paint than brush/roller due to overspray
• New plaster must be cured 28 days before painting — fresh alkalinity damages paint
• Add 5% wastage factor for estimation
• For BOQ: specify paint brand, type, number of coats, surface preparation
• Surface preparation (cleaning, sanding, filling cracks) is as important as the paint itself
