Aircon Grilles Dripping Water in Your Shop, Restaurant or Clinic? Commercial Anti-Condensation Fix
Water dripping from a supply grille is not a leak and not the aircon's fault. It's condensation on the diffuser — a slip hazard, a health-inspection flag, and it makes customers walk out. Shield22 Pro treats the ducting and grille surfaces so the drip stops without replacing your HVAC. Applied overnight; you open on time.
Why supply grilles drip
Supply-side ducting and grilles run at 12–16°C. Interior air at 24°C / 60% RH has a dew point of 16°C — any grille surface below 16°C will condense. That's every well-set cold-air distribution system in Singapore. Condensation collects on louvres, forms droplets, and drips onto customers, floor, or product displays.
The three commercial patterns
Retail: linear diffusers along shopfronts dripping onto display sills; customers slip on tile floors. F&B: ceiling cassette units dripping onto prep counters, dining tables, product cases — hygiene flag. Clinics: corner-mounted grilles dripping onto exam tables, dental chairs, animal treatment areas — infection-control concern.
The commercial Shield22 Pro process (business-hours-safe)
Site inspection with thermal imaging (S$120, waived on booking). Scope grille faces, adjacent bulkhead, 1m of upstream duct if accessible. Application overnight or single closure day; mall units 10pm–6am. Two-coat Shield22 Pro at 400 microns each. Ready for business next opening. From S$28/m² for commercial spec.
Case snapshot — Bugis F&B tenant, 220 m² cold-storage ceiling
Kitchen cold-storage ceiling weeping onto prep surface. Ceiling 14°C, ambient 26°C/78% RH. Applied Shield22 Pro over two nights (110 m² per night). Ceiling surface rose to 21°C, dripping stopped within 24 hours, 12-month follow-up dry and mould-free. Representative composite based on typical Pico X commercial jobs; documented case packs on request under NDA.
Insurance & landlord documentation
Every commercial job includes pre-work thermal images, moisture readings, application log, product data sheet, post-work thermal images showing surface temperature rise. Accepted by all major Singapore commercial insurers and mall landlord teams.
Shield22 Pro — the coating that stops condensation at source
Thermal micro-ceramic coating that raises the surface temperature above dew point so airborne moisture stops condensing. From S$18/m². 5-year condensation-free warranty. Non-toxic, low-VOC, safe for occupied rooms.

Frequently Asked Questions
- Can you work while my shop / restaurant / clinic stays open?
- For small grille-only jobs (1–2 diffusers) yes, screen off and complete in 3–4 hours. Larger jobs scheduled overnight or during your closure day. Zero business disruption is our standard offer.
- Will this affect our HVAC balance / airflow?
- No. Total dry film 0.8mm. Airflow unaffected. We coat the metal face and adjacent bulkhead — not inside the airway.
- Is Shield22 Pro food-safe / clinic-safe?
- Yes. Cured coating is inert, non-shedding, low-VOC. Safe over food-prep areas and in clinical environments. Healthcare-grade variant with additional MOH documentation available.
- What warranty for commercial spaces?
- 5-year condensation-free warranty backed by written scope and thermal-imaging evidence. Warranty transfers on landlord/tenant change.
- Do you handle mall / chain deployments?
- Yes. Multi-unit retail and F&B group experience — contact for chain-wide scoping and unit-price proposal.
- Can you also fix mould already growing on my grille?
- Yes — see /mouldy-aircon-grille-vent-singapore for wash-then-coat handoff in a single visit.
