Ask three bricklayers what plastering will cost and you’ll get three different answers — because the real number hides in wall area, not room count. In 2026, internal plastering runs about ₦1,500–₦2,200 per square metre (~$1.10–$1.60) supplied and applied, and external rendering about ₦1,700–₦2,800/m² (~$1.20–$2.00). A typical 3-bedroom bungalow lands around ₦0.95M–₦1.8M (~$680–$1,290); labour-only, where you buy cement and sand yourself, is roughly ₦600–₦1,200/m² (~$0.45–$0.85). (Figures at ₦1,400/$, August 2026.)
Plastering is the stage where a build suddenly looks like a house — and where a lot of first-time builders and diaspora owners get caught out. It’s not glamorous, nobody photographs it, and yet it quietly eats one of the bigger material-and-labour bills after blockwork. Here’s the honest 2026 breakdown, in naira and dollars, with the quantities so you can sanity-check any quote you’re handed.
What does plastering cost per square metre in 2026?
Most Nigerian plasterers price by the square metre of wall face, not by room. Two coats — a scratch coat and a finish coat — on internal walls is the standard. External walls cost more because the mix is richer and has to shrug off rain and sun.
| Work type (2026) | Cost per m² (₦) | ~ USD |
|---|---|---|
| Internal plaster, supply + apply (2 coats) | ₦1,500–₦2,200 | ~$1.10–$1.60 |
| External rendering, supply + apply | ₦1,700–₦2,800 | ~$1.20–$2.00 |
| Labour only (you buy cement + sand) | ₦600–₦1,200 | ~$0.45–$0.85 |
| Skim / POP smooth finish (extra) | ₦1,200–₦2,500 [VERIFY] | ~$0.85–$1.80 |
Lagos, Abuja and Port Harcourt sit at the top of these ranges because sand and labour cost more there. A village site with a local artisan and nearby sand pit can come in under them.
How much does it cost to plaster a whole house?
To get a house-level figure you need wall area, not floor area — and wall area is usually four to five times the footprint once you count both faces of every wall. These are working estimates; your architect’s actual wall schedule is the real answer.
| House type | Approx. plaster area | Cost range (₦) | ~ USD |
|---|---|---|---|
| 2-bedroom bungalow | ~400–500 m² | ₦0.7M–₦1.3M | ~$500–$930 |
| 3-bedroom bungalow | ~550–700 m² | ₦0.95M–₦1.8M | ~$680–$1,290 |
| 4-bedroom duplex | ~1,000–1,400 m² | ₦1.7M–₦3.6M | ~$1,210–$2,570 |
Worth knowing: These are plastering-only figures. They sit on top of your blockwork, and before painting. If a single contractor quotes you one lump sum for “finishing,” ask them to itemise plastering separately — it’s the only way to compare quotes fairly.
How much cement and sand does plastering need?
As a rule of thumb in 2026, every 100 m² of wall takes roughly 8–12 bags of cement (~$46–$130 worth) for two coats at the usual 12–15 mm thickness, plus sharp plaster sand. Thicker walls, uneven blockwork and rich external mixes push you to the top of that range.
Cement is the swing factor. A 50 kg bag ran anywhere from ₦9,000 to ₦15,000 (~$6.40–$10.70) across brands and states through mid-2026, with BUA usually a little cheaper than Dangote. On a 600 m² bungalow that’s about 50–70 bags just for plaster — so a ₦2,000 move in the cement price shifts your bill by ₦100,000–₦140,000.

What most plastering estimates leave out
Here’s the part the quick online calculators skip. First, preparation and hacking: if the blockwork is poor, the mason spends days chipping high spots and dubbing out hollows before a trowel of finish goes on — that’s labour nobody quoted. Second, scaffolding for storey buildings, which can add real money on a duplex. Third, wastage: 5–10% of mortar ends up on the floor, so buy sand and cement with a margin. Fourth, water and a mixer or extra hands if you’re plastering fast to beat the rains. And fifth — the big one for remote owners — supervision. A plasterer left unsupervised can stretch cement to save bags and pocket the difference, leaving you with weak, dusty walls that fail in two years. Budget for someone you trust to count bags on site.
Frequently asked questions
Is plastering priced per room or per square metre? Per square metre of wall face is the fair way. “Per room” quotes hide the fact that rooms differ in size and wall height — always ask for the rate per m².
Does POP or screeding change the price? Yes. A smooth skim, POP ceiling or wall screeding is separate work on top of basic plaster, roughly ₦1,200–₦2,500/m² [VERIFY] depending on finish and location.
How long does plastering a bungalow take? A small team plasters a 3-bedroom bungalow in about 2–4 weeks, allowing curing time between coats. Rushing the cure is the most common cause of cracks.
Should I supply materials or give a full contract? If you’re on site, supplying cement and sand yourself and paying labour-only (₦600–₦1,200/m²) is usually cheaper. If you’re abroad, a supply-and-apply contract with a trusted supervisor removes the daily material-counting headache.
How we sourced these figures: Rates are 2026 market ranges cross-checked against Nigerian construction cost references including Structville, cement pricing from major manufacturers such as Dangote Cement, and dollar conversions at ₦1,400/$ (August 2026). Prices vary by state, brand and site condition — treat them as planning ranges, not fixed quotes. Last updated: August 2026. Next review: November 2026.
