Current plastering prices interior walls in South Africa sit at R90 to R160 per square metre for two-coat sand-cement work in 2026, with exterior at R130 to R200 and a skim coat over sound plaster at R50 to R90.
Those are all-in figures covering materials and labour. Below is what sits behind each number, and why two quotes for the same wall can differ by half.
Plastering prices interior, exterior and ceilings
The headline rates, all per square metre of surface area, materials plus labour.
- Internal two-coat sand-cement: R90 to R160
- Internal skim coat over sound plaster: R50 to R90
- External two-coat with waterproofer: R130 to R200
- Decorative screed or textured finish: R160 to R260
- Labour only, any of the above: roughly R35 to R100
Other 2026 South African sources put labour alone at R77 to R132 per square metre and labour-plus-materials nearer R198 to R220, while national averages are often quoted as R80 to R150. The spread is real, and the drivers are below.
Ceilings are priced differently
A ceiling is not just an upside-down wall. Material has to hold overhead without slumping, the work is slower, and access equipment is needed in every room.
Most Cape Town ceilings are skimmed with a gypsum product rather than sand-cement plastered. Rates for that are set out in our ceiling skimming guide, which prices it as its own trade.
What actually moves the price
- Coat count. One coat versus two is the biggest single swing. A one-coat quote is not a cheaper contractor, it is less work.
- Wall condition. Hacking off failed plaster is a separate line item and often a large one.
- Access. Double storey means scaffolding, roughly R8 to R15 per square metre.
- Area size. Small jobs carry setup cost across fewer metres, so the rate per metre rises.
- Materials on whose account. Some rates exclude cement and sand entirely.
Wall condition is the item that ruins budgets. A house that needs its old plaster removed before anything new goes on is a different project from a new build, even though both are quoted per square metre.
Working out your own number
Measure walls, not floors. Multiply each wall’s length by its height, add them, then subtract doors and large windows.
- 4m x 4m room, 2.7m ceiling: about 43m2 of wall, minus roughly 2m2 for a door
- At R90/m2: around R3,700
- At R160/m2: around R6,600
Cape Town generally sits toward the upper half of national ranges, alongside Johannesburg. Use the top of the range for budgeting and treat anything lower as a bonus.
Materials as a share of the total
If you are buying materials yourself, the quantities are fixed and published. At 15mm thickness over 100m2 you need around 600kg of cement internally plus 2.3 cubic metres of sand — the maths is in our cement plaster mix ratio article, and sand costs are covered under plastering sand.
Reading a plastering quote
A quote worth comparing states all of these. If it does not, ask.
- Square metres, measured and listed per elevation or room
- Number of coats and total thickness
- Whether materials are included
- Preparation: hacking off, bonding agent, crack repair
- Access and scaffolding
- Whether VAT is in or out
- Curing and the wait before painting
Two quotes R50 per square metre apart are usually describing different scopes rather than different profit margins. Get both onto the same specification before you choose.
Where people overspend
- Full re-plaster when a skim would do. If the existing plaster sounds solid, R50 to R90 beats R90 to R160.
- Plastering over damp. It comes back, and then you pay twice.
- Decorative finishes on big areas. R160 to R260 per square metre adds up fast across a facade.
- Painting too early. Repainting a bubbled wall costs more than waiting 28 days.
The cheapest genuine saving is scope, not rate. Deciding room by room what really needs a full re-plaster usually beats negotiating a few rand off the metre. Mix ratios and workmanship standards are published by the South African Bureau of Standards.
Getting a firm figure
Rates like these are for planning. A real number needs someone to see the wall, because condition is the biggest unknown and nobody can price it from a photograph reliably.
Our brickwork and plastering quotes list area, coats, preparation and materials as separate lines. For the process itself see the wall plastering guide, or the plastering walls comparison for interior against exterior.

Frequently asked questions
How much is plastering per square meter in South Africa?
R90 to R160 per square metre for internal two-coat sand-cement plaster in 2026 including materials and labour, and R130 to R200 externally. Labour-only rates run roughly R35 to R100 per square metre, though some 2026 sources quote R77 to R132. A skim coat over sound existing plaster is cheaper at R50 to R90.
How much does plastering walls and ceilings cost?
Walls are quoted per square metre of wall area at R90 to R160 internally. Ceilings are priced as a separate trade because material has to hold overhead and access equipment is needed in every room. Most Cape Town ceilings are skimmed with a gypsum product rather than plastered with sand and cement, which is quoted differently again.
What is a reasonable cost to plaster a house?
Measure the total wall area rather than guessing from floor size. A modest three-bedroom home can easily run to 250 to 350 square metres of internal wall, so at R90 to R160 per square metre that is roughly R22,000 to R56,000 internally. External work is quoted separately at the higher exterior rate plus scaffolding.
What is the labour cost for plastering?
Labour alone is roughly R35 to R100 per square metre, with some 2026 South African sources quoting R77 to R132. The range depends on province, coat count and wall condition, with Cape Town and Johannesburg at the higher end. Always confirm whether a rate you are given includes cement, plaster sand and any bonding agent.
Why do plastering quotes vary so much?
Usually because they describe different work. The biggest swings are coat count, whether old plaster must be hacked off first, whether materials are included and whether scaffolding is needed. Ask every contractor to list square metres, coats, preparation, materials and VAT separately, then compare the quotes on the same specification.
