Painting Your Home in South Africa: Interior, Exterior, Prep & Cost

A fresh coat of paint is one of the most cost-effective ways to transform a home, but the result depends far more on preparation and the right paint than on the colour you pick. This guide covers what South African homeowners need to know.

Why is preparation the most important step?

Most paint failures, peeling, flaking, bubbling, come down to poor preparation, not bad paint. Proper prep includes:

• Cleaning surfaces of dust, grease and mould (a mould killer/wash is essential in damp areas)
• Scraping and sanding loose or flaking old paint
• Filling cracks and holes with the right filler (crack filler for walls, wood filler for trim)
• Sanding filled areas smooth
• Priming bare plaster, patches, new surfaces and stains
• Masking off windows, skirtings, edges and floors

A good painter spends a large share of the job on prep. If a quote seems cheap because it skips prep, the finish won't last.

Interior vs exterior: what's the difference?

Interior painting uses paints formulated for washability and low odour. Common choices:

• Matt/velvet for walls and ceilings (hides imperfections)
• Washable/low-sheen for high-traffic areas, kids' rooms and kitchens
• Enamel or water-based enamel for doors, trim and skirtings

Exterior painting has to survive harsh South African sun, UV, rain and temperature swings. It needs:

• Quality exterior PVA or acrylic wall paint with UV and weather resistance
• Proper waterproofing where needed (parapet walls, around windows)
• A plaster primer/masonry sealer on bare or chalky surfaces
• Attention to timing: avoid painting in direct harsh midday sun or before rain

Exterior work is more demanding and often needs more coats and better-grade paint, which is reflected in the price.

How much paint and how many coats?

As a rough guide, one litre of wall paint covers around 6 to 8 m² per coat on a prepared surface. Most jobs need two coats for an even finish, and dark or strong colours over light (or vice versa) can need three. Always buy a little extra from the same batch so colour matches for touch-ups. A good painter will calculate quantities from your actual wall areas.

How long does a paint job take?

• A single average room: roughly one day including prep and two coats
• A full interior of a 3-bedroom home: roughly 4 to 7 working days
• A full exterior: roughly 4 to 10 days depending on size, height and prep needed

Weather affects exterior timelines: paint needs dry conditions and adequate drying time between coats, so a rainy week can extend the job.

How do you choose a good painter?

• Ask to see photos or addresses of recent jobs
• Get a written quote specifying prep work, number of coats, paint brand and product
• Confirm whether paint and materials are included or quoted separately
• Ask about surface repairs (crack filling, waterproofing) explicitly
• Check they'll protect floors and furniture and clean up afterwards
• Agree on a payment schedule; avoid paying the full amount upfront

Red flags to avoid

• Quotes with no mention of preparation
• Full payment demanded before work starts
• Vague paint spec ("good quality paint") with no brand or product named
• No breakdown of coats
• Rushing to start without inspecting the surfaces first

What it typically costs

Painters usually price per square metre or per room, plus materials. As an indicative 2026 guide:

• Interior painting (labour only): roughly R25 to R60 per m²
• Interior painting (labour plus paint): roughly R45 to R100 per m²
• Exterior painting (labour plus paint): roughly R60 to R140 per m² depending on prep, height and waterproofing
• Single room repaint: roughly R1 500 to R4 500
• Full 3-bedroom interior: roughly R12 000 to R35 000
• Full house exterior: roughly R20 000 to R70 000+ depending on size and condition

Extra costs come from scaffolding for double-storey work, heavy crack repair, waterproofing and premium paints. These are broad ranges for the 2026 market and vary by region, surface condition, paint grade and scope, so always get an on-site assessment and written quote rather than relying on a fixed price.

Frequently asked questions

How often should I repaint? Interiors typically last 5 to 8 years; exteriors 5 to 10 years depending on sun exposure and paint quality. West- and north-facing walls that take heavy sun tend to fade and need attention sooner.

Is expensive paint worth it? For exteriors, yes, better paint resists UV, weather and fading far longer, so it works out cheaper over time. For low-traffic interior areas you can be more flexible.

Can I just paint over mould? No. Mould must be killed and washed off first, and the underlying damp cause addressed, or it will grow back through the new paint.

Do I need to move out during painting? Usually not. Painters work room by room, and modern low-odour interior paints make it manageable to stay, though it helps to clear furniture from work areas.

Should I supply the paint myself? You can, but many homeowners let the painter supply it so colour, quantity and quality are their responsibility. Either way, agree it in writing and specify the brand and product.

Key takeaways

• Preparation determines whether a paint job lasts; never skip it.
• Exterior paint must handle SA sun and weather, so use quality products.
• Most surfaces need two coats; strong colour changes may need three.
• Get a written quote specifying prep, coats and paint brand.
• Avoid paying in full upfront and be wary of quotes that ignore prep.
