How much paint do you need to build a house in Saint Kitts and Nevis?
A 150 m² single-storey house in Saint Kitts and Nevis needs roughly 94 litres of paint — about 0.63 litres per m² of floor area. That is computed from Saint Kitts and Nevis construction conventions, including the local wastage allowance.
Paint quantities for a house in Saint Kitts and Nevis, computed from how buildings are actually put up here rather than from a global average. The tables below run from a small 50 m² dwelling to a 400 m² family home, and the method section shows how to reproduce every figure by hand so you can adapt it to your own plan.
Paint by house size in Saint Kitts and Nevis
| Floor area | Paint required | Per m² of floor |
|---|---|---|
| 50 m² | 54 litres | 1.08 |
| 75 m² | 67 litres | 0.89 |
| 100 m² | 77 litres | 0.77 |
| 150 m² | 94 litres | 0.63 |
| 200 m² | 109 litres | 0.55 |
| 250 m² | 122 litres | 0.49 |
| 300 m² | 133 litres | 0.44 |
| 400 m² | 154 litres | 0.39 |
Single-storey. The per-m² rate falls as the house grows — a small house has more wall and roof per square metre of floor than a large one, which is why these are computed size by size rather than scaled from a single rate.

Plaster / render area External face plus both faces of internal walls | 471.8 m² |
What drives the quantity in Saint Kitts and Nevis
| Factor | Local value | Effect |
|---|---|---|
| Paintable area | External face + both internal faces | Internal walls are painted on both sides, which is why the paint area far exceeds the floor area. |
| Coats | 2 (plus primer) | Two finish coats is the practical minimum over new plaster; a primer or sealer coat is additional. |
| Coverage | ~10 m²/litre/coat | On smooth plaster. Rough render and unsealed masonry can halve it. |
| Substrate | 12 mm plaster internally | A properly floated plaster surface uses far less paint than a rough one — the saving is in the plastering, not the paint. |
How to calculate it yourself
- 01
Measure wall areas: external face once, internal walls on both faces, plus ceilings.
- 02
Deduct doors and windows only if they total more than about 10% of the wall — below that the deduction is inside the error of the estimate.
- 03
Divide by the coverage rate on the tin, then multiply by the number of coats.
- 04
Add a sealer or primer coat separately — its coverage is usually lower than the finish coat's.
- 05
Round up to whole tins, in the largest size available, which is materially cheaper per litre.
Buying and site notes
- —New plaster needs to dry fully before painting — weeks, not days. Paint applied over damp plaster blisters and peels.
- —Buy one batch per colour for the whole house; batch-to-batch colour variation is visible on a long wall.
- —Exterior grade on exterior walls, without exception. Interior paint outdoors fails within one wet season.

How much paint does a house need in Saint Kitts and Nevis?
+
A 150 m² single-storey house in Saint Kitts and Nevis needs roughly 94 litres of paint — about 0.63 litres per m² of floor area. That is computed from Saint Kitts and Nevis construction conventions, including the local wastage allowance.
How much paint per square metre in Saint Kitts and Nevis?
+
About 0.63 litres per m² of floor area for a single-storey house. The figure is not linear across sizes — a small house has proportionally more wall and roof per m² of floor than a large one, which is why the table above is computed size by size rather than scaled from one rate.
What changes the quantity of paint needed?
+
Paintable area (External face + both internal faces) — Internal walls are painted on both sides, which is why the paint area far exceeds the floor area. Coats (2 (plus primer)) — Two finish coats is the practical minimum over new plaster; a primer or sealer coat is additional. Coverage (~10 m²/litre/coat) — On smooth plaster. Rough render and unsealed masonry can halve it.
Is wastage included?
+
Where it applies, yes — a 5% allowance is carried on the perishable materials (walling units, tiles, paint). Bulk materials like sand and stone carry handling loss instead. Ordering the theoretical quantity with no allowance reliably means a second delivery at a worse price.
How accurate is this for my own house?
+
It is a planning quantity derived from a representative rectangular footprint, so it is the right order of magnitude and internally consistent — good for budgeting and for checking a supplier's list. It is not a measured takeoff of your plan. Upload your dimensioned drawings to get quantities measured off your real geometry and priced in XCD.
Are paint prices included?
+
No, deliberately. Material prices in Saint Kitts and Nevis move week to week and vary by region, so a price printed on a static page would be wrong within a month. This page gives you the quantity — take that to two or three local suppliers and the price will be current and competitive.
