When Cracks Can’t Wait

A sudden wall crack after heavy rains or renovation work isn’t just ugly—it can signal serious structural issues. At Best Painting Singapore, we’ve handled over 500 emergency hacking and painting services for:

  • Post-renovation stress cracks
  • Water damage emergencies
  • Pre-sale property touch-ups

Here’s our professional guide to fixing cracks properly, plus when you need urgent professional intervention.


Emergency Crack Assessment: Is It Dangerous?

🚨 Signs You Need Emergency Hacking & Painting Services

✔ Cracks widening daily (structural movement)
✔ Water leaking through walls (pipe bursts or flooding)
✔ Plaster chunks falling off (safety hazard)

Our Emergency Response:

  • Same-day temporary sealing

Step-by-Step Crack Repair (For Non-Emergencies)

Materials You’ll Need:

  • Nippon Fine Filler ($8.90/tube)
  • Ardex K 301 (for deeper cracks)
  • Sika Crack Flex (for moving cracks)

Professional Repair Process:

  1. Widen the crack (V-shape for better adhesion)
  2. Dust removal (compressed air works best)
  3. Flexible filler application (elastomeric for Singapore’s humidity)
  4. Reinforcement (fiberglass tape for cracks >2mm)

Pro Tip: For post-hacking cracks, always use polyurethane-based fillers—they handle structural stress better.

Painting Over Repaired Cracks: The Right Way

Critical Steps Most Contractors Skip:

  1. Alkali-resistant primer (neutralizes concrete pH)
  2. Elastomeric paint (stretches with building movement)
  3. Humidity-controlled drying (prevents bubbling)

Our Emergency Painting Protocol:

  • Industrial dehumidifiers on-site
  • Fast-cure primers (4hr recoat time)
  • Scaffold-free techniques for occupied homes

Prevention: Stop Cracks Before They Start

For Recent Renovations:

  • Wait 28 days after hacking before painting (concrete curing time)
  • Install expansion joints where walls meet ceilings
  • Use crack-bridging primer on fresh plaster

Emergency Prevention Kit:

  1. Temporary waterproof sealant (for sudden leaks)
  2. Stress crack monitors (alerts when widening)
  3. Our 24/7 hotline (+65 81935251)
