What the monsoon actually does to interior joinery
Swelling, glue line failure and the small detailing choices that prevent both.
Panels do not fail because they get wet. They fail because they get wet, dry, and get wet again, repeatedly, at an unsealed edge.
Every cut edge is an open door for moisture. Sealing them — banding, lacquer, even a coat of primer on a hidden edge — does more for longevity than moving up a grade while leaving edges raw. It is the cheapest reliability improvement available on any fit-out.
The second detail is clearance. A carcass sat flat on a floor that gets mopped will wick water upward through the base panel. A 75 mm plinth and adjustable feet solve it permanently.
The third is acclimatisation. Panels delivered in a dry month and installed immediately will take up moisture in the first monsoon and move. Letting sheets sit flat in the room for two days before cutting costs nothing and prevents a season of binding shutters.
