What Types of Ceiling Water Stains Require Professional Repair?
5 types of ceiling water stains signal damage beyond surface discolouration.
- Yellow-brown ring stains: Mineral deposits from evaporated water indicate a resolved or ongoing leak above
- Expanding dark stains: Active moisture migration through insulation and drywall layers
- Paint bubbling and peeling: Water trapped between paint layers causes delamination across 0.5 to 2 square metres
- Sagging texture with discolouration: Combined water weight and staining indicates saturated drywall requiring replacement
- Mould-tinged grey or black stains: Active mould colonies feeding on wet drywall paper backing

Is Painting Over a Water Stain a Permanent Fix?
No. Standard latex paint does not block water stain minerals. The yellow-brown discolouration bleeds through regular paint within 2 to 4 weeks. A proper repair requires 3 steps: source leak repair, stain-blocking shellac primer application, and colour-matched topcoat.
Without addressing the moisture source first, stains return within 30 to 90 days. Water Damage Ceiling Repair Ajax LLC confirms zero active moisture using a Tramex meter before applying any primer or paint in Ajax homes.
