Plastering Cost in Nigeria: Wall Prices per m², Labour and Materials

Plastering cost in Nigeria is usually compared per square metre of wall surface. The first question is whether the rate covers labour only or labour and materials. The second is whether the work is new internal plastering, external rendering, a skim finish or repairs. Those scopes should be identified before you compare prices.

Use the price panel on this page for Skillland’s published planning estimates. Select your location where available, then ask a plasterer to measure the work and give a written quotation. A general plastering estimate should not be treated as a specific price for every finish.

1. Plastering, rendering and skimming: what are you paying for?

For budgeting, describe the surface and intended finish rather than relying on a trade name alone. Internal plastering may involve bringing bare block walls to an agreed finish. External rendering covers outside wall surfaces. Skimming is a thin finishing treatment over a suitable existing surface; it is not the same scope as building up plaster on bare, uneven blockwork.

Ask the contractor to identify the proposed materials, preparation and finish. If your specification includes more than one stage, make sure the quotation covers each stage. Painting should be separately identified even when the final objective is a painted wall.

2. How to measure plastering area

Plastering is measured on the faces being finished, not simply from the floor area of the house. A wall 5 metres long and 3 metres high has a gross area of 15 m² on one face. Finishing both faces gives a gross area of 30 m² before adjustments for openings and returns.

For a rectangular room measuring 4 metres by 5 metres with walls 3 metres high, the gross internal wall area is 2 × (4 + 5) × 3 = 54 m². This excludes the ceiling and is before deductions or other agreed measurement adjustments.

These are measurement examples, not typical Nigerian room sizes. Ask how the quotation treats doors, windows, reveals, columns and small openings. Agree that measurement basis before comparing two contractors’ totals.

3. Labour only or labour and materials?

Labour only: confirm preparation, application and finishing tasks. Obtain the separate material schedule and clarify who supplies water, tools and access equipment.
Labour and materials: confirm the specified materials, delivery, handling and application scope. Check whether removal of loose existing finishes is included.
Separate items: ask about scaffolding, repairs, decorative finishes, skimming, painting and waste removal. Do not add these twice if they are already included in the agreed rate.
A low labour rate may cover fewer tasks. Compare quotations against the same measured quantities and finish before deciding which offers better value.

4. Budgeting for a three-bedroom bungalow

The number of bedrooms is not enough to calculate a plastering bill. Wall height, room layout, external wall area, openings and the faces being finished all affect the quantity. A compact bungalow and a larger house with the same bedroom count can require substantially different amounts of work.

Build a schedule with separate quantities for internal walls, external walls, ceilings if applicable, and repairs. Multiply each quantity by its own agreed rate and add separately priced work. For a larger project, ask for a measured bill of quantities rather than relying on a single whole-house allowance.

5. What can increase the quotation?

Uneven or damaged backgrounds, removal of old finishes, working at height, difficult access and small isolated repair areas can change the work involved. Explain whether the building is occupied and whether floors, doors or furniture need protection.

Show the contractor any damp areas or cracks before agreeing the scope. Ask for the cause to be assessed where needed and for preparatory repairs to be identified separately. A new finish should not be used to conceal an unresolved problem.

6. Agree the finish before work starts

Ask to see comparable completed work and agree the required appearance, corners and edges. For a large job, a sample area can help establish what both parties expect. Include the proposed sequence, drying and curing requirements for the chosen system, and the point at which the surface can receive its next finish.

Before handover, review the agreed areas with the contractor and record defects or unfinished items. If a concern may involve the underlying wall, ask the relevant building professional to assess it rather than treating every crack as a cosmetic plaster repair.

7. Get a plastering quote for your property

Send your state and town, photographs, approximate wall areas, building height and required finish. Say whether you want labour only or materials supplied. Explore plastering services or post your project on Skillland. For walls still at the construction stage, the blockwork cost guide explains how to separate wall construction from finishing.

8. Frequently asked questions

How much does plastering cost per square metre in Nigeria?
Start with the published price panel for the relevant location and scope, then obtain a measured quotation. Confirm whether the rate is labour only or labour and materials, and whether preparation, external work, skimming and access equipment are included.

How do I calculate plastering cost for a three-bedroom house?
Measure the wall faces being finished and separate internal plastering, external rendering and other work. Multiply each measured quantity by its agreed rate. Bedroom count alone does not establish the wall area or final cost.

Is skimming included in a plastering quotation?
Only if the written scope includes it. Ask what surface finish the plastering rate delivers and whether a separate skim coat and painting are required. Skimming over an existing surface is a different scope from plastering bare blockwork.
