Roof deck waterproofing should be completed before paint, ceiling, and interior finishing to reduce leaks and rework risks.
Waterproofing Is Not an Extra Stage
In Bali’s tropical buildings, roof deck waterproofing is an essential construction stage, not an add-on after leaks appear. If waterproofing is delayed, paint finishing, ceilings, and interiors can be damaged before the building is ready to use.
When Should Waterproofing Be Done?
Ideally, waterproofing is applied after the roof deck surface is strong, clean, and has the correct water slope. Before coating, cracks, corners, drains, and wall junctions should be inspected.
Risks of Skipping It
- Stained and damp ceilings.
- Bubbling or peeling wall paint.
- Higher rework cost because finishing must be opened again.
- Disputes between structural and finishing contractors.
Waterproofing Quality Control
Project supervision should make sure materials match specifications, critical areas receive additional treatment, and ponding tests are done when possible. Photo documentation before finishing is closed is also important for owner records.
Conclusion
Proper waterproofing protects finishing quality and property value. For renovation or construction in Bali, this stage should be controlled before painting and interior work begins.
