Planning Interiors That Survive the Kerala Monsoon

Kerala's long monsoon and year-round humidity are hard on interiors. Most of the swelling shutters, peeling edges and black spots we are called to fix come from choices made at the design stage. Here is what we look at before we build.

Use the Right Board in the Right Place

Not every cabinet needs the most expensive board, but wet areas do. Under the kitchen sink, in bathroom vanities and in utility areas we use boiling-water-resistant (BWR/BWP) plywood. Plain MDF and particle board soak up water at the edges and do not recover once they swell.

Seal Every Edge

Moisture gets in through cut edges, not the laminate face. Machine-applied edge banding on all four sides of a shutter, including the hidden top and bottom, makes a large difference to how long a kitchen lasts.

Let the Air Move

Leave a small gap behind wardrobes on external walls so they do not trap damp air.
Add ventilation slots or louvred panels to shoe racks and store rooms.
Fit an exhaust fan in every bathroom and over the hob, and use it.

Fix the Wall Before You Finish It

Paint, wallpaper and panelling only hide seepage for a while. If a wall shows damp patches, the source (a terrace, a pipe, a gap in the window frame) needs repair first. We check walls with you during the site visit before suggesting finishes.

Choose Finishes That Are Easy to Wipe

Laminates, acrylic and lacquered glass handle humidity better than raw veneer in kitchens. Veneer works beautifully in bedrooms and living rooms when it is properly polished and sealed.
