Key Differences: Interior Painting vs Exterior Painting in Singapore
Interior painting focuses on aesthetics, cleanability, and low emissions for living spaces. Use BCA-approved low-VOC paints to comply with NEA rules—formaldehyde in interior paints will be banned above 0.01% from Jan 1, 2026[3]. Popular 2025 trends include warm neutrals and biophilic greens for cozy HDBs[1].
Exterior painting requires weatherproof paint and outdoor paint to battle UV rays, rain, and humidity. Expect 4-7 year lifespan here, shorter than interior's 5-10 years due to tropical exposure[2][4]. Light colors reflect heat, essential for condos and landed homes.
| Aspect | Interior | Exterior |
|---|---|---|
| Paint Type | Low-VOC, mold-resistant | Weatherproof, UV-resistant |
| Prep | Clean, patch, prime | Power wash, treat mold |
| Timing | Year-round | Dry season (Mar-Sep)[2] |
| Lifespan | 5-10 years | 4-7 years[4] |
DIY Tips for Interior Painting: Safe for Singapore Homes
DIY shines for small interior jobs like accent walls in your HDB living room. Start with quality tools from Mustafa Centre (Little India, open 24/7, MRT Farrer Park Exit A, 5-min walk). Insider tip: Test Nippon Momento Anti-Bacterial paints—mold-resistant for humid bedrooms[1].
- Prep: Clean with sugar soap, patch holes with filler, sand smooth. Ventilate—open windows despite AC.
- Prime: Apply low-VOC primer on bare walls.
- Paint: Two coats with 4-inch roller for edges, 9-inch for walls. Dry 4 hours between coats.
- Clean-up: Use drop cloths; dispose waste per NEA guidelines.
Cost: S$200-500 for a room (paint S$50/gallon). Limit to low-risk areas—avoid kitchens/bathrooms needing pros for HDB compliance[5]. Link to costs: Interior vs Exterior Painting Cost Guide: Singapore Prices 2025 | Homejourney.
Why Skip DIY for Exterior Painting in Singapore
Exterior DIY risks safety on high-rises—ladders fail in gusts, common in windy Jurong or Changi areas. Pros use scaffolding, boom lifts, mandatory for condos over 3 stories per BCA rules[2]. Humidity demands anti-fungal priming; amateurs miss this, leading to peeling[1].
Pro tip: Schedule March-September for dry weather; use apps like WeatherSG. For landed properties, check URA for color approvals. Always hire PUB/EMA-certified for compliance[1]. See fixes: Common Interior vs Exterior Painting Problems & Fixes | Homejourney SG.
