Plastering prices per m2 in Cape Town sit at R90 to R160 per square metre for a standard internal two-coat sand-and-cement finish in 2026, with materials and labour included. External walls run higher at R130 to R200, and ceilings land between R95 and R135.
Those are the numbers. What most homeowners actually need is a way to turn them into a total for their own house, so this guide works through real examples.
Plastering prices per m2 at a glance
Every plasterer prices by area, not by room. Here is the 2026 rate card for Cape Town, all-in unless stated.
- Internal two-coat sand-cement: R90 to R160 per m²
- Interior standard wall plaster: R85 to R120 per m²
- Ceilings: R95 to R135 per m²
- External two-coat with waterproofing additive: R130 to R200 per m²
- Skim coat over sound existing plaster: R50 to R90 per m²
- Decorative screed or textured finish: R160 to R260 per m²
Labour on its own, if you buy the sand and cement yourself, is roughly R85 to R130 per m² for both coats. A scratch coat alone is R50 to R78, a finish coat alone R42 to R68.
Why the range is so wide
The same wall can be quoted at R95 or R150 without either plasterer being dishonest. Wall condition, height, access and job size all move the figure. Our guide to plastering rates per m2 South Africa unpacks exactly which factors do what.
Worked example one: a single bedroom
Take a bedroom measuring 4m by 3.5m with 2.7m ceilings, one door and one window.
- Wall perimeter: 4 + 3.5 + 4 + 3.5 = 15m
- Gross wall area: 15m × 2.7m = 40.5 m²
- Deduct openings: a door at roughly 1.8 m² and a window at roughly 2 m²
- Net wall area: about 36.7 m²
At R90 per m² that room is about R3,300. At R160 it is about R5,870. The ceiling adds 14 m² at R95 to R135, so another R1,330 to R1,890.
So a plastered bedroom, walls and ceiling, lands somewhere between R4,600 and R7,800 in 2026. That spread is normal, and it is why you compare rates rather than totals.
Worked example two: a whole house
A three-bedroom single-storey home of about 130 m² floor area typically has 320 to 400 m² of internal wall surface once you allow for internal partitions.
- 360 m² internal walls at R90: R32,400
- 360 m² internal walls at R160: R57,600
- 130 m² ceilings at R95 to R135: R12,350 to R17,550
- 150 m² external walls at R130 to R200: R19,500 to R30,000
Full-house plastering therefore runs roughly R64,000 to R105,000. Double storey pushes it up again because scaffold hire adds R8 to R15 per m² on the external elevations.
Measuring your own walls
Measure each wall length, multiply by ceiling height, add them up, then subtract doors and large windows. Do not deduct small windows, because the plasterer still has to cut and finish the reveals around them. Mix ratios and workmanship standards are published by the NHBRC.
What the per-square-metre price should include
A rate is only comparable if you know what sits inside it. Ask every quote to confirm these in writing.
- Both coats, not a scratch coat with the finish coat priced later
- Sand, cement and bonding agent where the quote says all-in
- Corner beads and angle beads on external corners
- Site clean-up and removal of plaster waste
- Making good around door and window reveals
Things usually excluded are scaffolding, chasing for electrical conduit, crack repair to existing walls, and any painting afterwards. If you need cracks dealt with first, our wall crack repair guide explains which ones matter.
Checking a plastering quote in Cape Town
Three quotes on the same wall will differ. These checks tell you which one is real.
- Does it state a rate per m² and the area? A single lump sum hides everything.
- Does it name the mix? SANS 2001-EM1 sets 1:5 cement to plaster sand internally and 1:4.5 externally.
- Does it state thickness? Internal work is typically 12 to 15mm, external 15 to 20mm.
- Does it allow curing time? New plaster needs 28 days before painting.
- Is the sand specified? Washed plaster sand, not building sand.
Sand quality is where cheap quotes quietly cut corners, and it shows up as cracking within a year. Our page on plastering sand price in Cape Town shows what the material actually costs, so you can see whether a low rate is even possible.
Getting an accurate figure for your home
Per-square-metre pricing is a planning tool, not a quote. The only way to firm it up is to have someone measure the walls and look at their condition.

Frequently asked questions
How much is plastering per square meter in South Africa for plastering prices per m2?
R90 to R160 per square metre for a standard internal two-coat sand-and-cement finish in 2026, including materials and labour. Interior standard wall plaster is often quoted at R85 to R120, ceilings at R95 to R135, and external walls with a waterproofing additive at R130 to R200 per square metre.
How much does it cost to plaster a room for plastering prices per m2?
A 4m by 3.5m bedroom with 2.7m ceilings has roughly 37 square metres of wall after deducting a door and a window. At R90 to R160 per square metre that is R3,300 to R5,870 for the walls, plus R1,330 to R1,890 for the 14 square metre ceiling. Budget R4,600 to R7,800 for both.
What does plastering cost for a whole house?
A three-bedroom single-storey home of about 130 square metres usually has 320 to 400 square metres of internal wall. Allowing for ceilings and external walls, full-house plastering runs roughly R64,000 to R105,000 in 2026. Double storey costs more because scaffold hire adds R8 to R15 per square metre externally.
Is labour-only plastering cheaper?
Labour only runs about R85 to R130 per square metre for both coats, against R90 to R160 all-in. The saving is small once you buy sand, cement and bonding agent yourself, and you carry the risk of ordering the wrong quantities or the wrong grade of sand. Most homeowners are better off with an all-in rate.
How do I measure the area to be plastered?
Measure each wall’s length, multiply by the ceiling height, and add the walls together. Subtract doors and large windows, but leave small windows in, because the plasterer still finishes the reveals around them. Ceilings are simply the floor area of the room. Give those figures to every plasterer so quotes are comparable.
