Humidity in Pattaya is 70–90% year-round. That's not just a weather station number. It's an aggressive environment that destroys every finishing material designed for dry climates.
Paint, wallpaper, drywall, decorative plaster — all these materials were designed for 40–60% humidity. In the tropics, they degrade 2–3 times faster than the manufacturer states.
What Humidity Does to Standard Materials
| Material | Lifespan in Europe | Lifespan in Tropics | What Happens |
|---|---|---|---|
| Paint (latex) | 5–7 years | 1–3 years | Bubbles, cracks, yellowing, mold |
| Wallpaper | 7–10 years | 3–6 months | Peels off, mold grows underneath |
| Drywall | 15–20 years | 1–2 years | Swells, crumbles, mold from inside |
| Decorative plaster | 10–15 years | 2–3 years | Cracks, flakes off |
| PVC Stretch Membrane | 15+ years | 15+ years | Nothing — PVC doesn't react to moisture |
Why PVC Membrane?
The MSD Premium membrane is a non-porous PVC material, 0.17–0.22 mm thick. It:
- Blocks moisture — in both directions. Creates a sealed barrier
- Doesn't rot or grow mold — unlike any porous coating
- Doesn't deform — PVC is stable from 0 to 60°C
- Easy to clean — a damp cloth twice a year. No special products needed
- Holds water — during leaks the membrane holds up to 100 L/m²
How It Works on Walls and Ceilings
The stretch membrane is installed on a frame with a 2–3 cm gap from concrete. This creates:
- Air cushion — natural ventilation between membrane and concrete
- Sealed barrier — moisture from concrete doesn't enter the room
- Hidden space — for wires, pipes, and AC units
