Renovation During Hong Kong’s Humid Season: 5 Essential Tips
Every year from March to April, Hong Kong enters the “Return of Southern Warmth” (回南天) season, with humidity levels consistently reaching 80-95%. While renovating during this period is entirely possible, homeowners need to take extra precautions to ensure quality results.
Paint work requires a complete moisture-resistant system — from primer to topcoat — with each layer needing 48-72 hours to dry properly. Using putty-based wall filler instead of traditional vegetable glue powder creates a crystalline waterproof layer that significantly reduces mold risk.
Woodwork demands special attention as timber naturally absorbs moisture. All wood materials should acclimatize indoors for 3-5 days before installation, and moisture-resistant E0 or E1 grade boards (around HK$180-280 per 4×8ft sheet) are strongly recommended.
Tiling work requires longer drying times — wait at least 7-10 days before grouting to prevent hollow spots. Full adhesive coverage on tile backs is essential rather than the traditional dot method.
The silver lining? March-April is the industry’s off-peak season, meaning contractors are more available, quotations can be 5-10% lower, and craftsmen can take their time for superior workmanship. A typical 400 sq ft flat renovation takes 55-70 working days during this period versus 45-60 days normally.
