Want glass that stays cleaner for longer, resists water marks, and repels mineral deposits in Singapore’s relentless tropical climate? Lion City Glass applies professional nano hydrophobic glass coatings across Singapore — an invisible protective treatment that dramatically reduces glass maintenance, prevents hardwater staining, and makes surfaces easier to clean. Ideal for shower screens, facade glass, pool panels, skylights, and any glass surface exposed to water and the elements in our humid equatorial environment.
If you are tired of scrubbing water stains off your shower screen every week, watching your condo windows cloud up within months of cleaning, or paying for frequent professional glass maintenance — nano glass coating is the long-term solution that saves you time, effort, and money.
What Is Nano Hydrophobic Glass Coating?
Nano hydrophobic coating is a liquid treatment applied to glass surfaces that bonds at the molecular (nanoscale) level, creating an ultra-thin, invisible hydrophobic (water-repelling) barrier. When water hits a treated glass surface, it forms tight beads and rolls off rapidly — rather than spreading into a flat film that leaves behind mineral deposits when it evaporates.
The science is straightforward: Singapore’s tap water and rainwater contain dissolved minerals — primarily calcium and magnesium. When water sits on untreated glass and evaporates, these minerals are deposited on the surface as white, chalky hardwater mineral stains. Over time, these deposits build up layer upon layer until the glass appears permanently cloudy. Nano coating prevents this cycle by stopping water from adhering to the glass in the first place.
Key properties of our professional-grade nano glass coating:
- Hydrophobic — Water beads tightly and rolls off the surface, carrying dirt and contaminants with it
- Oleophobic — Resists oil, grease, and fingerprint marks for cleaner-looking glass
- Anti-mineral — Dramatically reduces calcium and magnesium deposit formation from tap water and rainwater
- UV resistant — Maintains performance under Singapore’s intense equatorial sunlight without degrading
- Optically clear — Completely invisible once cured; does not change glass appearance, colour, or transparency
- Long-lasting — Durability of 12 to 36 months depending on the application surface and exposure level
- Self-cleaning effect — Rain and rinse water actively carry away surface contaminants on coated exterior glass
Why Singapore Properties Need Nano Glass Coating
Singapore’s combination of high humidity, frequent rainfall, hard tap water, and intense UV radiation creates the perfect conditions for rapid glass deterioration. Property owners across Singapore — from HDB flat dwellers to landed homeowners to commercial building managers — face a constant battle against water stains, mineral deposits, and biological growth on glass surfaces.
Nano hydrophobic coating directly addresses this by creating a barrier between the glass and the water that causes all these problems. Property owners who apply nano coating after professional glass polishing and restoration typically experience:
- Up to 90% fewer hardwater spots on shower screens and bathroom glass within the first year
- Dramatically easier daily cleaning — a quick wipe replaces heavy scrubbing with chemical cleaners
- Longer intervals between professional restoration — extending from 6 months to 12 to 18 months in many cases
- Reduced cleaning product usage — less need for harsh chemical cleaners that can themselves damage glass over time
- Glass that looks cleaner, longer — maintaining a fresh, sparkling appearance between maintenance visits
- Lower long-term maintenance costs — the upfront coating investment pays for itself within the first year for most properties
Where We Apply Nano Glass Coating in Singapore
Nano hydrophobic coating is versatile and effective on virtually any glass surface. Here are the most popular applications across Singapore residential and commercial properties:
Shower Screens
By far the most popular application in Singapore homes. Shower screens in HDB flats, condos, and landed homes are constantly exposed to hard tap water, soap scum, and body oils. Without protection, they develop stubborn white mineral stains within weeks. Nano coating keeps shower glass clearer for months, dramatically reducing the need for professional shower screen restoration. We recommend coating as a follow-up treatment after every shower screen restoration job.
Facade and Window Glass
Condominium windows, office building facades, and shopfront glass exposed to rain and urban pollutants benefit significantly from nano coating. The hydrophobic effect causes rainwater to sheet off quickly, reducing mineral deposits and keeping the glass cleaner between scheduled facade glass cleaning and restoration visits. For high-rise buildings, this can mean significant savings on rope-access cleaning costs.
Skylights and Roof Glass
Horizontal and angled glass surfaces collect the most rainwater and suffer the worst mineral staining. Nano coating on skylights reduces water pooling, inhibits biological growth, and extends the intervals between professional skylight cleaning. Learn more about our skylight glass cleaning and restoration service.
Swimming Pool Glass Panels
Pool-adjacent glass panels in condominiums and landed homes are exposed to chlorinated water splashback and mineral-heavy pool water. Nano coating provides excellent protection against chlorine staining and calcium buildup on pool fencing and viewing panels.
Balcony, Terrace, and Outdoor Glass
Glass railings, balustrades, canopy panels, and terrace enclosures on Singapore properties face constant outdoor exposure. Nano coating protects these surfaces from rainwater mineral deposits, tree sap, bird droppings, and airborne pollutants, keeping them cleaner with less maintenance effort.
Our Nano Coating Application Process
For best results, nano hydrophobic coating must always be applied to thoroughly clean, contaminant-free glass. Coating applied over stained or dirty glass will seal in the existing damage and produce poor results. That is why we always assess the glass condition first and recommend completing a glass restoration treatment before coating application when necessary.
- Glass condition assessment — We inspect the glass surface for mineral stains, scratches, chemical etching, and other contamination that must be addressed before coating.
- Glass preparation or restoration — Thorough cleaning or full restoration (including polishing and scratch removal if needed) to ensure a pristine, residue-free surface for coating adhesion.
- Surface decontamination — IPA (isopropyl alcohol) wipe-down to remove any remaining oils, fingerprints, or microscopic residues from the glass surface.
- Nano coating application — Our technicians apply the nano coating evenly across the entire glass surface using professional application techniques that ensure uniform coverage without streaks or missed areas.
- Curing period — The coating is allowed to bond with the glass surface at the molecular level. Curing time varies depending on the product and ambient conditions.
- Water bead quality check — We perform a water test to verify the coating is performing correctly, checking bead formation and roll-off behaviour.
- Care instructions — We provide detailed maintenance guidance to help you maximise the coating’s longevity and performance, including which cleaning products to use and which to avoid.
Nano Glass Coating Pricing in Singapore

Frequently Asked Questions About Nano Glass Coating
How long does nano hydrophobic coating last?
Durability depends on the surface location, exposure level, and cleaning frequency. Shower screens — which face daily water exposure and regular wiping — typically maintain effective performance for 12 to 18 months. Exterior facade and window glass coatings, which are exposed to rain but wiped less frequently, may last 24 to 36 months. Re-application is straightforward and cost-effective, especially when done during a scheduled maintenance visit.
Is nano coating safe for all glass types?
Yes. Our professional-grade nano coating is compatible with standard float glass, tempered glass, laminated glass, low-E glass, and virtually all glass panel types used in Singapore residential and commercial buildings. It does not alter the glass appearance, colour, or structural properties in any way.
Does nano coating require special cleaning products?
No special products are needed. Standard, non-abrasive glass cleaners or simply water and a soft microfibre cloth are all you need for routine cleaning of nano-coated glass. The key is to avoid harsh abrasive cleaners, scouring pads, or acidic cleaning agents that can physically degrade the coating layer and reduce its lifespan. We provide specific care instructions with every coating application.
Can nano coating be applied without prior glass restoration?
Only if the glass is already clean and free from mineral stains, scratches, and chemical damage. Coating applied over stained or damaged glass will seal in the existing imperfections and produce poor results — you will have a hydrophobic coating over cloudy glass, which defeats the purpose. We always assess the glass condition before coating and will recommend hardwater stain removal or chemical stain restoration first if needed.
Is nano glass coating worth the investment?
For most Singapore property owners, absolutely. Consider the alternative: without coating, a typical shower screen requires professional restoration every 6 to 9 months at SGD 200 to 400 per visit, plus weekly scrubbing with chemical cleaners. With nano coating applied after restoration, the next professional treatment can be pushed out to 12 to 18 months, and daily maintenance becomes a 30-second wipe instead of a 15-minute scrub. The coating typically pays for itself within the first cycle.
Can I apply nano coating myself using retail products?
Consumer-grade nano coating products are available, but they typically offer significantly shorter durability (weeks rather than months) and inconsistent performance compared to professional-grade coatings. Professional application also ensures proper surface preparation — which is the most critical factor in coating performance and longevity. For the best results and longest-lasting protection, professional application is strongly recommended.
How do I know when the nano coating needs re-application?
The simplest test is the water bead test: run water over the coated glass surface. If water still beads tightly and rolls off quickly, the coating is performing well. If water begins to spread and sit on the glass in flat patches, the coating is wearing thin and should be re-applied. We also notice that cleaning becomes harder as the coating degrades — if you find yourself scrubbing harder than you used to, it is time for a re-coat.
