DesignAI suggests the right primer, finish and prep for your door material and climate — and sense-checks how much paint to buy.
Assumptions & notes
- Paintable area per door ≈ 2.2 × one leaf face — this covers both faces, the four edges and a little for the frame rebate. Heavily carved or panelled doors need a bit more.
- Coverage assumed ~12–14 sqm per litre per coat for smooth, primed surfaces. Bare, porous or rough timber drinks more — round up and keep a touch-up tin.
- Paint is sold in 1 L tins here (also 0.5 L / 4 L), so litres are rounded up to whole cans — you will usually have some left over.
- Costs are indicative India 2026 and shown including 18% GST on the paint. Brand, sheen and city change the price; primer is costed at ~₹280/L.
- This is a planning aid, not a substitute for a painter or carpenter. If the door is warped, water-damaged or the old coat is flaking, prep (sanding, filling, a fresh primer) matters more than the topcoat — a carpenter may be needed first.
