If dehumidifiers work, why don't you sell them?

They work for room humidity but not for a specific cold surface. If your ceiling is 5°C below dew point, a dehumidifier only cuts dew point by ~2°C — the ceiling still condenses. Plus S$30–60/mo forever. Shield22 Pro fixes the surface once.

Why is insulation more expensive if it's just foam?

Materials are cheap; ceiling demolition, false-ceiling framing, plasterboard, skimming, and painting is 80% of the cost.

Can I do all three at once?

Yes and some jobs do. But 90% of homes solve with one method chosen for the specific surface.

At a glance

Shield22 Pro coating: S$450–1,800 upfront, half-day disruption, exact affected surface only, zero ongoing cost, 5-yr warranty, no headroom loss, fixes cause. Insulation (PU/rockwool): S$1,200–2,500, 3–5 days disruption + ceiling demolition, whole surface, zero ongoing cost, materials warranty only, loses 100–150mm headroom, fixes cause. Dehumidifier: S$500 + S$30/mo, no disruption, one room only, S$30–60/mo ongoing, 2-yr appliance warranty, no headroom loss, fixes symptom (room humidity).

When Shield22 Pro coating wins

Isolated cold surfaces (one wall, one ceiling section, aircon ledge, cold pipe). You can't or don't want to reduce headroom. Rental / short-term. Cause is a neighbour's aircon. Want zero ongoing electricity cost.

When insulation wins

You're already renovating and adding a false ceiling. Affected area is large and you don't need the headroom. You also want noise insulation. New build — install properly during construction.

When a dehumidifier wins

Small room with general damp problem (wardrobe, bomb shelter, storeroom). Renting and can't modify surfaces. Interim measure. Walk-in wardrobe with leather goods needing low humidity year-round.

Combining options

Ceiling drip + walk-in wardrobe: coating + dehumidifier. New condo aircon room: rockwool + Shield22 Pro on aircon ledge. HDB corridor bedroom: coating + curtain repositioning + fan-only habit.

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.
