Bathroom Waterproof Paint Singapore
Bathroom Waterproof Paint Singapore: Zinsser WaterTite LX
How much does Zinsser WaterTite LX waterproofing cost?
S$488 is the starting price for a standard HDB bathroom ceiling waterproofing scope using Zinsser WaterTite LX. It is a vapour-breathable, liquid-blocking coating for wet-zone substrates, including bathroom ceilings, walls, planter walls and AC ledges. Full bathroom waterproofing starts from S,280.
The waterproof paint Pico X Health puts down before any wet-zone topcoat. Vapour-breathable, liquid-blocking, hydrostatic-rated — the right physics for bathrooms, planter walls, AC ledges, and basement concrete in Singapore's tropical climate.
✓ Every Pico X Health Signature service is applied with Zinsser.
What it solves
Most Singapore "leak" complaints aren't leaks — they are hydrostatic pressure pushing moisture through concrete from the other side of the wall (planter, balcony, neighbour's bathroom). A standard interior paint, even an anti-mould one, eventually blisters because the substrate is wet underneath the film.
WaterTite LX is the layer that stops that. It cures into a flexible film that passes vapour but blocks liquid water — the right physics for a tropical wet wall.

- Zinsser sealer where the substrate is dusty or chalky.
- Two coats Zinsser WaterTite LX at documented wet-film thickness.
- Cure window — min 24 hours before overcoat, 7 days before tile.
