Petaling Jaya is one of Malaysia’s oldest planned townships, with large swathes of SS2, SS3, PJS, Damansara Utama, Damansara Jaya and Taman Mayang terraces built between the 1960s and 1990s. These homes share a common challenge: carbonated cement render. Over decades, atmospheric CO² reacts with the lime in the original plaster, neutralising its alkalinity and making it brittle, chalky and porous. When the render becomes carbonated, paint adhesion drops sharply — even a quality repaint starts peeling within 2–3 years if the substrate is not treated first.
The second major issue in PJ is north-facing and shaded walls. PJ’s dense street-tree canopy and terraced row layout means many side and rear walls stay damp for hours after rain, creating ideal conditions for Cladosporium (black mould) and green algae. Standard paint repaints over this without treatment; the mould returns within 6–12 months. The correct approach is antifungal wash, alkali-resistant primer, then an anti-mould top coat.
Older PJ condos in PJ Old Town, SS2 and Kelana Jaya follow different rules: interior repaints are straightforward (management approval not needed for interior colour changes), but exterior facade repaints require JMB/MC sign-off. See the exterior section below.
The tables below cover typical 2026 indicative pricing for PJ properties. Cost varies by wall condition (more prep = more cost), paint tier and scaffolding requirements for upper storeys.
| Scope | Indicative cost (PJ) | Notes |
|---|---|---|
| Single room interior repaint | RM450 – RM800 | Labour + mid-range paint; basic prep |
| Whole condo/apartment interior | RM3,000 – RM7,000 | 700–1,200 sq ft; 2 coats |
| Single-storey terrace interior | RM3,500 – RM6,500 | ~1,000–1,400 sq ft built-up |
| Double-storey terrace interior | RM5,000 – RM9,000 | ~1,400–2,200 sq ft built-up |
| Terrace exterior (single-storey) | RM2,500 – RM5,000 | Masonry + fascia + parapet |
| Terrace exterior (double-storey) | RM4,000 – RM10,000 | Includes scaffolding for upper facade |
| Waterproof coating (parapet/flat roof) | RM8 – RM18 per sq ft | Elastomeric / acrylic membrane |
| Paint cost per sq ft (interior, labour + paint) | Budget | Mid-range | Premium |
|---|---|---|---|
| Rate per sq ft | RM2.00 – RM2.80 | RM2.80 – RM4.00 | RM4.00 – RM5.50 |
| Typical paint brand | Nippon Vinilex, local brands | Nippon 5-in-1, Dulux Easy Clean | Dulux Ambiance, Nippon Momento |
| Washable / anti-mould | No | Yes | Yes + better coverage |
| Expected repaint cycle (PJ humidity) | 3–5 years | 5–8 years | 7–10 years |
PJ’s age and tropical humidity call for specific product choices. Here is how the main categories compare for PJ’s typical property stock:
| Paint type | Best for | PJ suitability | Indicative cost / L |
|---|---|---|---|
| Interior emulsion (economy) | Low-traffic rooms | Poor on mouldy walls — repaints over the problem | RM18 – RM35 |
| Anti-mould interior emulsion | Bathrooms, shaded rooms, PJ terrace bedrooms | Good — fungicide additive slows regrowth | RM40 – RM75 |
| Weatherproof masonry (exterior) | All PJ exterior walls | Essential — standard paint cracks on carbonated render | RM55 – RM120 |
| Elastomeric waterproof coating | Flat roofs, parapets, water-retaining walls | Highly recommended for older PJ flat-roof terraces | RM80 – RM160 |
| Anti-carbonation coating | Carbonated render surfaces | Specialist coat — seals pores and extends repaint cycle | RM90 – RM180 |
For most PJ terraces with aged render, the most cost-effective stack is: antifungal wash → alkali-resistant primer → weatherproof masonry top coat (2 coats). Skipping the primer on carbonated render is the single biggest cause of early paint failure in this township.
A full interior repaint of a PJ terrace or condo typically covers:
What is typically not included in a standard interior repaint: kitchen tiles, bathroom tiles, roof undersides, external fascias, or feature wall textured finishes (these are priced separately).
See our house painting cost guide → for full national price ranges, and the paint types & finishes guide → for a deeper comparison of emulsion options.
PJ’s terraced rows mean exterior walls are shared or very close — scaffolding is often needed for the upper two floors of a double-storey, and access sometimes requires coordination with the neighbour. Plan for this in your timeline and budget. Key exterior considerations for PJ homes:
Mould on PJ terrace walls is not merely a cosmetic issue — it indicates a persistent moisture pathway, usually from a combination of condensation, driving rain on porous render, or minor plumbing seepage. Painting straight over it without treatment yields results that look good for 6–12 months then return visibly worse. The correct process:
If mould returns within 1–2 years even after proper treatment, the underlying render likely needs to be hacked and replaced. This is a plastering job, not a painting job — we can advise and quote both.

Petaling Jaya falls under Majlis Bandaraya Petaling Jaya (MBPJ). For a straight repaint in the same or similar colour, no formal approval is typically required. However, if you intend to change the exterior colour significantly — especially in heritage or gazetted residential areas, or if the building is commercial-grade — it is good practice to check with MBPJ’s Building Department first. Some mature PJ neighbourhoods have informal colour harmonisation guidelines maintained by residents’ associations (RA). For strata condo owners in PJ: exterior walls and facades are common property under the Strata Management Act 2013 (Act 757). You cannot repaint or alter the exterior facade without written approval from your JMB or MC. Interior repaints are at the owner’s discretion.
