Painting is often priced, advertised and compared as a rate per square metre. Published Kenyan painting rates vary widely, and the scope behind them is not always stated consistently. One rate may cover labour for a single coat; another may cover preparation, materials and a full painting system.
A painting rate per square metre is only useful when you know what the rate includes. This guide explains what sits behind a per-m² figure and how to compare two of them fairly.
Why “KSh X per m²” needs labels
On its own, a figure such as “KSh X per m²” cannot be compared with anything. Two rates can only be compared when they describe the same four things.
| Label | What to ask | Why it matters |
|---|---|---|
| Area basis | Which area has been measured: paintable wall or surface area, or floor area? | A home's floor area and its paintable wall area are different numbers. The same rate applied to each gives a different total. |
| Scope | Labour only, supply and apply, or a complete preparation-and-painting system? | A labour-only rate leaves the materials to be bought separately. A complete-system rate should include preparation, materials and every coat. |
| Coats | Is the rate per coat, or for the completed system? | A typical interior system on new plaster is an undercoat and two finish coats. A per-coat rate covers only one of them. |
| Condition | Sound repaint, new plaster, or walls needing repairs and preparation? | Preparation can cost as much as the painting itself. Skimming rough plaster is very different from repainting a sound wall. |
When someone gives you a rate per square metre, ask which area has been measured. FinishGrid estimates painting from paintable surface area rather than assuming floor area equals wall area.
How the paint part of a rate is formed
Part of any supply-and-apply rate is the paint itself. Its cost per square metre can be worked out from three things:
Paint cost per m² =
- Price per litre
- ÷ Coverage per coat
- × Number of coats
Here is that arithmetic for an interior silk or washable finish paint, using FinishGrid's figures:
| Market reference price | KSh 12,500 – 15,000 per 20 L bucket (FinishGrid market reference range) |
|---|---|
| Price per litre | KSh 625 – 750 |
| Coverage | 12–14 m² per litre per coat on a smooth, previously painted wall (FinishGrid quantity-v1 coverage, based on Kenyan technical data) |
| Paint per m², one coat | KSh 44 – 63 |
| Paint per m², two finish coats | KSh 89 – 125 |
The low end pairs the lower price with the best coverage, the high end pairs the higher price with the poorest coverage, and both are rounded outwards to the nearest shilling. The price range reflects realistic market purchasing across neutral product categories, not one manufacturer's list price.
This figure is the finish paint only. It leaves out the preparation coat, filler and other preparation materials, labour, and the fact that paint is bought in whole buckets. To turn your own wall area into litres and packs, calculate your paint quantity.
FinishGrid worked example: two scopes, two rates
Dividing a full project estimate by the wall area gives an effective cost per square metre. The FinishGrid worked example below does this for the same 150 m² of interior wall surface in two conditions. Each figure includes preparation, paint and materials, and labour.
| Item | Sound repaint | New rough plaster |
|---|---|---|
| Work assumed | Light preparation, two finish coats | Full skimming, sanding, one preparation coat, two finish coats |
| Expected project range | KSh 32,500 – 43,400 | KSh 62,000 – 102,500 |
| Effective cost per m² of wall | KSh 216 – 289 | KSh 413 – 683 |
Both examples assume an apartment, Standard finish level and one colour, with no ceilings, doors, trim or repairs. Per-m² figures are the project range divided by 150, rounded outwards. They are worked examples that show how scope changes a rate. They are not a Kenyan average and not a quotation. The full breakdown is in Cost of Painting a House in Kenya.
The same 150 m² of wall produces a very different effective rate depending on the work involved. That is why a rate quoted without its scope tells you so little.
Per coat or completed system?
A rate per coat and a rate for a completed system are easy to confuse. If one painter quotes per coat and another quotes for the complete job, the per-coat figure will look cheaper even when it is not. To compare them, work out how many coats the job needs (for example, one undercoat and two finish coats on new plaster) and whether preparation is priced separately.
Labour-only rates raise the same question from a different angle: what the labour covers and how it is priced. Painting Labour Costs in Kenya explains that side of a quotation.
Before you compare two rates
Before comparing two per-m² painting rates, ask:
- Which area is being measured?
- Is the rate labour only, or are materials included?
- Is preparation included, and how much (cleaning, filling, sanding, skimming)?
- How many coats are included?
- What paint or product specification is included?
- Is the rate per coat or for the completed system?
- Are access, transport or other project requirements included?
Frequently asked questions
Is the lowest per-m² rate the cheapest option overall?
Not necessarily. A low rate may be labour only, per coat, or exclude preparation. Once materials, every coat and preparation are added, the total can be higher than a quote with a higher all-inclusive rate.
Why do published painting rates vary so much?
Partly because they describe different things: different area bases, scopes, coat counts and wall conditions. Rates also vary between painters, products and locations.
Should I ask for a per-m² rate or a total price?
Either can work. What matters is that the scope is written down: which walls, what preparation, which products, how many coats and what is excluded. A total price with a clear scope is easier to check than a rate with no scope.
