HDB painting projects: Avoiding common surface preparation errors

Frequently Asked Questions

Proper surface preparation ensures the paint adheres correctly, resulting in a smooth, long-lasting finish and preventing issues like peeling or blistering.
Common mistakes include not cleaning surfaces thoroughly, skipping priming, neglecting to repair damages, and using the wrong type of preparation products.
Remove dust, dirt, grease, and mold with a suitable cleaner and rinse thoroughly. For greasy areas, use a degreaser. Ensure the surface is completely dry before painting.
Yes, priming is highly recommended. It improves paint adhesion, seals porous surfaces, blocks stains, and provides a uniform surface for the new paint layer.
Use a suitable filler to fill cracks and holes. Allow it to dry completely, then sand it smooth before priming and painting.
Use medium-grit sandpaper (120-150 grit) for general sanding and fine-grit sandpaper (220 grit) for smoothing surfaces after applying filler or primer.
Ensure proper ventilation, use mold-resistant paint, and clean surfaces regularly with a mold-killing solution. Address any underlying moisture issues.
