Condensation-Free Ceilings for Vitasoy’s Hong Kong Warehouse

Posted on: 14/08/2025

Case Study — Vitasoy Warehouse, Hong Kong: Condensation-Free Ceilings with RD-Aquasorb

Sector: Food & beverage logistics
Location: Hong Kong
Substrate: Interior warehouse ceilings (mixed concrete/metal deck)
Solution: RD-Aquasorb, waterborne moisture-regulating coating

The Challenge

Hong Kong’s subtropical climate is tough on warehouses.

High humidity, strong daily temperature swings, and chilled or air-conditioned interiors create the perfect conditions for condensation on cold ceiling surfaces.

At Vitasoy’s distribution facility, that meant:

  • Drips onto packaging and pallets during peak humidity
  • Slippery floors and safety concerns in busy aisles
  • Higher housekeeping costs and risk of staining or microbial growth
  • Reduced visibility due to dull, stained ceilings

Vitasoy needed a hygienic, durable, and fast interior solution—one that would reduce condensation risks without long shutdowns or heavy odors.

Why RD-Aquasorb

RD-Aquasorb is a high-performance, waterborne coating designed for interiors where condensation and intermittent dampness are a concern. Unlike many mould-resistant paints, it contains no added biocides—its unique spongy microstructure physically absorbs excess moisture from the air and gradually releases it when conditions change, reducing drip formation. At the same time, it delivers a clean, bright, matte finish that improves light reflectance.

Key advantages for Vitasoy’s site

  • Condensation management: Spongy structure buffers moisture without chemical additives.
  • Hygiene & compliance: Smooth, washable, low-odor film suitable for active food & beverage environments. Does not contain biocides!
  • Speed: Rapid drying allows staged application with minimal downtime.
  • Low VOC & waterborne: Safer to apply indoors, with less disruption to operations.
  • Aesthetics: Bright white, uniform finish lifts overall visibility in racking corridors.

Scope & Preparation

  • Zones: High-traffic pallet aisles, loading bays, and staging areas beneath HVAC ducting—where cold air met humid inflow.
  • Surface prep: Localized cleaning to remove dust, loose particles, and any residues; masking of luminaires and sprinkler heads; light mechanical abrasion where needed.
  • Application method: Airless spray for speed and uniformity on large ceiling areas; rollers for edges and detail work.
  • Staging: Executed in phases to keep logistics flowing—one aisle set isolated while adjacent zones remained operational.

Application Highlights

  • Film build & uniformity: Controlled passes ensured an even, matte finish—critical for consistent condensation behavior across the surface.
  • Detailing around penetrations: Particular attention around cold bridges (steel beams, duct hangers) where condensation typically initiates.
  • Lighting boost: The fresh white ceiling noticeably improved ambient brightness, aiding barcode scanning and visual inspections.

Results

1) Less Drip, More Control
Post-installation monitoring during humid spells showed a marked reduction in drip events—especially around cold spots and air handling runs. Staff reported fewer slip-risk callouts and less need for protective sheeting over staged pallets.

2) Cleaner, Brighter Warehouse
The uniform matte white finish improved light distribution, enhancing visibility in picking aisles and loading zones.

3) Minimal Disruption
Phased, fast-dry application meant aisles returned to service quickly. The low-odor, waterborne chemistry fit seamlessly into an active food & beverage environment.

4) Easy Maintenance
The coated surface is easy to clean and refresh, supporting long-term hygiene standards.

Lessons for Similar Facilities

  • Map your cold bridges. Identify beams, ducts, and penetrations where condensation starts.
  • Choose coatings that manage moisture naturally. RD-Aquasorb’s structure controls condensation without relying on biocides.
  • Plan for phased execution. With fast-dry, waterborne systems, you can keep logistics running during upgrades.
